Subject: Revision to Letter AJG-89-031, dated May 19, 1989, "Consulting Support for Qualification of Welding Technique for Temperbead Welding on Indian Point Unit 2 Steam Generator Shell"

Dear Steve:

The purpose of this letter report is to document my review of the results of the subject temperbead welding qualification test program conducted by Welding Services Incorporated (WSI) for Consolidated Edison Company. The temperbead qualification was performed for the Indian point Unit 2 (IP-2) steam generator shell. The shell material is SA302 Grade B low alloy steel, designated by the ASME Code as P-3 Group 3 material.' The purpose of the temperbead qualification was to be prepared to perform a cavity weld repair to one or more of the IP-2 steam generator shells using this welding approach, such that an elevated temperature (11500F) post weld heat treatment would not be required. ASME Code Case N-432, issued in February, 1986 [1], provided guidance for the temperbead qualification activity at WSI. Both weld parameter trial tests (on a thinner plate of SA302 B material) and procedure qualification tests (on a thicker plate) were performed in order to select a weld procedure and then to qualify it. Although a dilemma arose wherein the thicker plate was not entirely representative in terms of toughness, the results on the thinner and thicker plates, taken together, demonstrate that the procedure should be technically acceptable for use on the 3.5 inch thick steam generator shell at IP-2, as discussed in the following sections of this report.

Weld Trials

In the technical program undertaken for the qualification, WSI performed a technical evaluation of eight (8) different automatic gas tungsten arc welding (GTAW) approaches for welding the SA302 B cavity. The welding approaches included a welding technique which reproduced the Babcock and Wilcox approach which formed the basis for ASME Code Case N-432 [2], as well as modifications to that approach to improve the ease of welding in the field.

May 31, 1989 S. Burkhalter AJG-89-0 35

Following the welding of eight test coupons of SA302 B plate using these eight different welding techniques, metallurgical and microhardness measurements were performed on the test coupons [3]. The microhardness measurements revealed that three of the welding techniques produced a weld heat affected zone (HAZ) hardness well below Rockwell C hardness 37, an upper bound reference hardness used for selecting a welding process as suitable for use in the temperbead procedure qualification. These three welding techniques included the Reference 1 approach and two approaches where the travel speed was adjusted to provide for greater ease of welding. WSI selected technique P-6, one of the two travel speed adjusted welding techniques, for procedure qualification in accordance with Code Case N-432. The microhardness results for the P-6 welding approach are presented in Table 1 [3]. One notes from Table 1 that the maximum hardness in the HAZ in the technique P-6 plate is Rc 33.5, well below the Rc 37 target value. Thus, this procedure appears quite capable of meeting the HAZ requirements of this representative base material.

One additional weld trial was conducted using the P-6 weld parameters. A single bead weld was deposited on the SA302 B plate and the hardness measured in. the HAZ of the plate. This test would compare the untempered hardness with the tempering ,anticipated using the P-6 welding technique. The results of that single bead weld are presented in Table 2, from Reference 3. One observes from Table 2 that the untempered weld HAZ contains a maximum hardness of Rc 49, more than 15 hardness points higher than the tempered P-6 process HAZ. These results confirmed the fact that the temperbead process developed using the P-6 welding technique is representative of a welding process which should produce a base metal weld HAZ which is substantially softer than an untempered structure. Based upon these results and the ease of application of this welding process, the P-6 welding approach was selected as the preferred approach for the temperbead weld procedure qualification.

Weld Procedure Qualification

The Weld Procedure Qualification Record [4] specifies welding a 3 inch deep groove weld into a 7.125 inch thick plate of SA302 B material. The material type and minimum thickness of the plate and the groove for procedure qualification were specified by Code Case N-432 and by Section XI of the ASME Code [5]. The required tensile, side bend, drop weight and Charpy v-notch specimens were removed from the plate following welding and tested at Applied Technical Services, Inc. The tensile test results and the side bend test results were certified to be acceptable as presented in the Applied Technical Services, Inc. certified test reports [6].

May 31, 1989 S. Burkhalter AJG-89-035

The base metal drop weight specimens produced a no break condition in duplicate-specimens at +40OF whereas the weld metal produced a no break condition at -10°F. The Code Case requires the reference nil ductility transition temperature of the weld metal and the base metal to be no greater than +600F, and the weld HAZ to have Charpy v-notch absorbed energy and lateral expansion equal to or greater than the unaffected base metal at the nil ductility transition temperature plus 600F. Since the reference temperature from the all weld metal drop weight specimens was -206F, the Charpy tests were conducted at +40°F and the requirements of the Code Case and the Code were met. Since the reference temperature from the base metal drop weight tests was +300F, the Charpy v-notch tests for the base metal and the HAZ were performed initially at 900F. The base metal specimens did not meet the 1980 ASME Section III values for determining reference NDT at +900F. However the HAZ energy absorbed and lateral expansion were far superior to the base metal properties, thereby meeting that requirement of the Code Case. The Charpy v-notch results for these tests are presented in Attachment 1 [6).

A second series of base metal and HAZ impact tests were performed at +120°F in an attempt to meet the Code of repair requirements at the maximum temperature allowed by the Code Case for the base metal. The results of these tests are presented in Attachment 1. The base metal tests again failed to meet the Code toughness requirements at the maximum temperature alIowed by the Code Case. However, note that the HAZ impact toughness is still superior to the base metal toughness at 120°F, attesting to the adequacy of the weld procedure.

Conclusions

The properties of the base metal used in the temperbead qualification program did not meet all of the requirements of Code Case N-432 and the Code of repair. However, application of these requirements in this case is overly restrictive. The plant was constructed to ASME Section III, 1965 with addenda through 1966, a Code which prescribed less in the way of toughness requirements for this material than either the Code of repair, or Code Case N-432. The intent of Code Case N-432 is to assure that the weld procedure which is qualified, qualifies a process on representative material which provides assurance that the welding process has not degraded the base metal. The HAZ Charpy v-notch energy absorbed and lateral expansion were clearly greater than those of the unaffected base metal in this test program. The 7.125 inch thick SA302B plate used in this test program is representative material in that section thickness. One

ASSCIATES M


characteristic of this material is its poor through thickness hardenability, thereby resulting in plate which in this thickness, may have poor notch toughness in the 1/4t to 3/4t region. In reduced section thicknesses, this material is expected to have better toughness.

The steam generator shell at IP-2 is significantly thinner, 3.5 inches thick, and has superior Charpy v-notch impact properties compared to the test plate as would be expected for this grade of material. The steam generator shell impact strength exceeds the minimum construction code requirements of 30 ft-lbs at +10°F as contrasted to approximately 30 ft-lbs at 120°F for the 7.125 inch thick test plate. Were the test -plate a more representative thickness, I believe that the notch impact properties would have been significantly improved. This observation is substantiated by the weld trial tests in the thinner plate (2.25 inches thick), where hardness measurements revealed a softened HAZ consistent with increased toughness for a representative material. The restrictions of Code Case N-432 required a thicker plate than is to be welded to in the field thereby restricting the qualification program to use of a base metal which could not be reasonably expected to meet the notch toughness requirements in the Code Case. Consequently, while all requirements of Code Case N-432 cannot be literally adhered to, I believe that, when considering both the trial weld .tests and the procedure qualification tests taken together, a clear demonstration has been made that the HAZ properties have not been degraded in the SA302 B plate and that the temperbead process is technically qualified for use at IP-2.

I trust that this document meets your requirements regarding the qualification of this process. If you have additional questions, or require additional information, please do not hesitate to call.

Very truly yours,

SUBJECT: Relief Request Regarding Temperbead Welding on 9, /4/A Indian Point Unit No. 2 Steam Generator Shell

As a contingency measure for the 1990 mid-cycle outage for Indian Point Unit No. 2, Consolidated Edison has been planning the development and qualification of an automatic gas tungsten arc welding (GTAW) temperbead process to be available for steam generator girth weld repair. The automatic GTAW temperbead process is a welding process which produces a tempered, as deposited, heat-affected zone microstructure and weldment properties which are similar to that of GTAW weld deposits which have been post weld heat treated. The qualification requirements for the GTAW procedure cannot be met to the letter of the applicable ASME code case due to the unavailability of the test material required as stated.

Attachment A contains a brief discussion and basis upon which Consolidated Edison hereby requests that the NRC grant relief, per 10 CFR 50.55a subparagraph(6)(i), from strict interpretation of Code Case N-432 for this repair procedure.

Attachment B contains the detailed weld procedure qualification package for your review. I

Regulatory Input Related to Relief Request Regarding Temperbead Welding of Low Alloy Steel Vessel Materials

Using GTAW

Consolidated Edison Company of New York, Inc. Indian Point Unit No. 2

Docket No. 50-247 July, 1989

In anticipation of need, Consolidated Edison has developed a temperbead weld qualification program for the Indian Point Unit No. 2 steam generator shell. The shell material is SA302 Grade B low alloy steel, designated by the ASME Code as P-3 Group 3 material. The purpose of the temperbead qualification was to be prepared to perform a cavity weld repair to one or more of the IP-2 steam generator shells using this welding approach, such that an elevated temperature (llSOOF) post weld heat treatment would not be required. ASME Code Case N-432, issued in February 1986, provided guidance for the temperbead qualification activity. Both weld parameter trial tests (on a thinner plate of SA302 Grade B material) and procedure qualification tests (on a thicker plate) were performed in order to select a weld procedure and then to qualify it. Although a dilemma arose wherein the thicker plate was not entirely representative in terms of toughness, the results on the thinner and thicker plates, taken together, demonstrate that the procedure should be technically acceptable for use on the 3.5 inch thick steam generator shell at IP-2, as discussed below.

The properties of the base metal used in the temperbead qualification program did not meet all of the requirements of Code Case N-432 and the Code of repair. However, application of these requirements in this case is overly restrictive. The plant was constructed to ASME Section III, 1965 with addenda through 1966, a Code which prescribed less in the way of toughness requirements for this material than either the Code of repair, or Code Case N-432. The intent of Code Case N-432 is to assure that the weld procedure which is qualified, qualifies a process on representative material which provides assurance that the welding process has not degraded the base metal. The HAZ Charpy v-notch energy absorbed and lateral expansion were clearly greater than those of the unaffected base metal in this test program. The 7.125 inch thick SA302B plate use in this test program is representative material in that section thickness. One characteristic of this material is its poor through thickness hardenability, thereby resulting in plate ,which, in this thickness, may have poor notch toughness in the 1/4t to 3/4t region. In reduced section thicknesses, this material is expected to have better toughness.

The steam generator shell at IP-2 is significantly thinner, 3.5 inches thick, and has a superior Charpy v-notch impact properties compared to the test plate as would be expected for this grade of material. The steam generator shell impact strength exceeds the minimum construction code requirements of 30 ft-lbs at +lOOF as constrasted ;to approximately 30 ft-lbs at 120OF for the 7.125 inch thick test plate. Were the test plate a more representative thickness, we believe that the notch impact properties would have been significantly improved. This observation is substantiated by the weld trial tests in the thinner plate (2.25 inches thick), where hardness measurements revealed a softened, HAZ consistent with increased toughness for a representative material. ; The restrictions of Code Case N-432 required a thicker plate than is to be welded to in the field thereby restricting the qualification program to use of a base metal which could not be reasonably expected to meet the notch toughness requirements in the Code Case. Consequently, while all requirements of

a'I

Code Case N-432 cannot be literally adhered to, we believe that, when considering both the trial weld tests and the procedure qualification tests taken together, a clear demonstration has been made that the HAZ properties have not been degraded in the SA302 Grade B plate and that the temperbead process is technically qualified for use at IP-2.

In addition, the ASME Section XI Special Working Group on Repair by Welding will formally include the use of automatic GTAW temperbead in the code. This will be addressed during the summer 1989 meeting. Additionally, the ASME has realized that the present N-432 code case for automatic GTAW temperbead, as it now exists, is unworkable, specifically for thick section plate qualification. As a result, the committee is recommending the following changes to the weld qualification requirements:

o The test assembly shall be of the same "P" number and Group number as the component being repaired.

o The base metal impact properties shall meet the design specification.

o The average of the three charpy V-notch HAZ results shall be equal or greater than the average of the three base metal impact values.

In conclusion, Consolidated Edison believes that the strict interpretation of Code Case N-432 for this temperbead repair of SA302 Grade B steam generator shell material is clearly impractical and that the weld procedure, as prepared, is technically adequate.

Consolidated Edison, therefore, requests relief from the full requirements of Code Case N-432 such that the weld procedure already developed is acceptable and qualified.

Subject: Additional Information Regarding Through Thickness Properties of A302 B in Thick Sections

Dear Steve:

As a result of our telephone conversation of May 25, 1989, and your request for additional data regarding the through-thickness properties of A302 Grade B pressure vessel steels in thick sections, I have performed an additional literature review, with the assistance of Fred Copeland, of the properties of this class of lowalloy steel. -As you know, A302-B isrepre-s-entativ-. off -a' pressure vessel steel which is not generally used today inthick nuclear vessel applications due to its lack of through-thickness hardenability. Consequently, -a literature review involves examination of relatively old data from limited sources. Two reference documents were located from which this letter report was prepared (References 1 & 2). Reference 1 is a background technical report from Lukens Steel entitled "Heavy Gage Plate Steels for Nuclear Service". Reference 2, appended to this letter report, is entitled "Utilization of Quenching and Tempering for Improvement of Low Alloy Steels in Heavy Thickness for Welded Construction".

One of the characteristics of most steels is the fact that in the solid state, minor changes in composition and/or in heat treatment can produce dramatic changes in properties of the steel. For example, in a carbon or low alloy steel, a rapid cooling from. above the austenitizing temperature can produce a very strong bainitic or martensitic structure, whereas slower cooling will produce a ferrite-pearlite microstructure. The bainitic or martensitic structure, once properly tempered, will produce a high yield strength, high-toughness material, whereas, the ferrite-pearlite structure will have lower toughness and lower yield and ultimate tensile strength. One notes that the only fabrication differences between the high strength, high toughness structure and the low strength, low toughness structure is cooling rate. This cooling rate from austenitizing heat treatment temperature. is a function of quench medium, plate thickness and location in the plate through-thickness direction (surface vs. mid-wall, etc.) However, for a given cooling rate

S. Burkhalter May 31, 1989 AJG-89-034

(defined by the above parameters), the tendency of a steel to transform to bainite and/or martensite can be enhanced by further increasing the alloying or carbon content to increase the hardenability of the steel. Hardenability, therefore, can be defined as an index of the depth to which martensite or bainite can be formed in a given steel as the result of a given hardening treatment and cooling rate.

The A302 Grade B low alloy steel pressure vessel material has somewhat limited hardenability in: thick sections as illustrated in Figures 1 through 3, from Reference 1. One notes from Figure 1 for A302-B plate with additional nickel, that the. Charpy-v-notch toughness decreases dramatically as plate thickness is increased. Figures 2 and 3 illustrate that the yield and ultimate tensile strengths are also dramatically decreased as plate thickness increases. Even in the quenched and tempered condition, the notch toughness of the A302-B steel is degraded in thicker sections as illustrated in Figure 4 (Reference 2).

As a result of the toughness and hardenability problem in thick sections., steel producers developed a second -generation _of__. reactor steels (Reference 1), steels which included the A543, A542 and A533.designation of low alloy steels. The A533 Grade B became the modern generation replacement material to A302 Grade B. The basic difference between A533-B steel and A302-B is the fact that the second generation material contains some nickel which lowers the nil ductility transition (NDT) temperature and improves notch toughness of the A533-B material (Reference 1). Although some through-thickness problems do indeed still exist in the second generation A533-B materials, the dramatic reduction in the NDT temperature (typically to less than 0°F), and the large improvement in notch toughness due to the nickel addition, more than compensate for the through-thickness hardening deficiency in thick sections.

In summary, the through-thickness hardenability problem which exists in A302 Grade B low alloy steel pressure vessel material also exists to a lesser degree in the modern generation replacement material, A533 Grade B. However, the nickel addition produces such a dramatic increase in upper shelf notch toughness and dramatic decrease in NDT temperature that the hardenability problem can be tolerated in this modern material. For applications involving thick section plates, the residual elements, such as Cr, and other elements are also typically mainatined near the top end of permitted limits, in order to get an additional "boost" in hardenability and, thus, in through-thickness strength and toughness. The lower toughness A302-B material does not provide the toughness margin provided in the A533-B. It is for that reason that we had difficulty meeting the base metal toughness requirements in thick sections in the A302-B material.

Subject: Consulting Support for Qualification of Welding Technique for Temperbead Welding on Indian Point Unit 2 Steam Generator Shell

Dear Steve:

The purpose of this letter report is to document my review of the results of the subject temperbead welding qualification test program conducted by Welding Services Incorporated (WSI) for Consolidated Edison Company. The temperbead qualification was performed for the Indian point Unit 2 (IP-2) steam generator shell. The shell material is SA302 Grade B low alloy steel, designated by the ASME Code as P-3 Group 3 material. The purpose of the temperbead qualification was to be prepared to perform a cavity weld repair to one or more of the IP-2 steam generator shells using this welding approach, such that an elevated temperature (1150 F) post weld heat treatment would not be required. ASME Code Case N-432, issued in February, 1986 [1], provided guidance for the temperbead qualification activity at WSI. Both weld parameter trial tests (on a thinner plate of SA302 B material).and procedure qualification tests (on a thicker plate) were performed in order to select a weld procedure and then to qualify it. Although a dilemma arose wherein the thicker plate was not entirely representative in terms of toughness, the results on the thinner and thicker plates, taken together, demonstrate that the procedure should be technically acceptable for use on the 3.5 inch thick steam generator shell at IP-2, as discussed in the following sections of this report.

Weld Trials

In the technical program undertaken for the qualification, WSI performed a technical evaluation of eight (8) different automatic gas tungsten arc welding (GTAW) approaches for welding the SA302 B cavity. The welding approaches included a welding technique which reproduced the Babcock and Wilcox approach which formed the basis for ASME Code Case N-432 [2], as well as modifications to

,-"that approach to improve the ease of welding in the field.


Following the welding of eight test coupons of SA302 B plate using these eight different welding techniques, metallurgical and microhardness measurements were performed on the test coupons [3]. The microhardness measurements revealed that three of the welding techniques produced a weld heat affected zone (HAZ) hardness well below Rockwell C hardness 37, an upper bound reference hardness used for selecting a welding process as suitable for use in the temperbead procedure qualification. These three welding techniques included the Reference 1 approach and two approaches where the travel speed was adjusted to provide for greater ease of welding. WSI selected technique P-6, one of the two travel speed adjusted welding techniques, for procedure qualification in accordance with Code Case N-432. The microhardness results for the P-6 welding approach are presented in Table 1 [3]. One notes from Table 1 that the maximum hardness in the HAZ in the technique P-6 plate is Rc 33.5, well below the Rc 37 target value. Thus, this procedure appears quite capable of meeting the HAZ requirements of this representative base material.

One additional weld trial was conducted using the P-6 weld parameters. A single bead weld was.deposited on the SA302 B plate and the hardness measured in the HAZ of the plate. This test would compare the untempered hardness with the tempering anticipated using the P-6 welding technique. The results of that single bead weld are presented in Table 2, ofrom Reference 3. One observes from Table 2 that the untempered weld HAZ contains a maximum hardness of Rc 49, more than 15 hardness points higher than the tempered P-6 process HAZ. These results confirmed the fact that the temperbead process developed using the P-6 welding technique is representative of a welding process which should produce a base metal weld HAZ which is substantially softer than an untempered structure. Based upon these results and the ease of application of this welding process, the P-6 welding approach was selected as the preferred approach for the temperbead weld procedure qualification.

Weld Procedure Qualification

The Weld Procedure Qualification Record [4) specifies welding a 3 inch deep groove weld into a 7.125 inch thick plate of SA302 B material. The material type and minimum thickness of the plate and the groove for procedure qualification were specified by Code Case N-432 and by Section XI of the ASME Code [5]. The requiredtensile, side bend, drop weight and Charpy v-notch specimens were removed from the plate following welding and tested at Applied Technical Services, Inc. The tensile test results and the side bend test results were certified to be acceptable as presented in ,-the Applied Technical Services, Inc. certified test reports [6). The base metal drop weight specimens produced % --- a /STU CTdMU

• .- TE IIM


condition in duplicate specimens at +40°F whereas the weld metal produced a no break condition at -10°F. The Code Case requires the reference nil ductility transition temperature of the weld metal and the base metal to be no greater than +600 F, and the weld HAZ to have Charpy v-notch absorbed energy and lateral expansion equal to or greater than the unaffected base metal at the nil ductility transition temperature plus 600F.

Since the reference temperature from the all weld metal drop weight specimens was -200F, the Charpy tests were conducted at +40°F and the requirements of the Code Case and the Code were met. Since the reference temperature from the base metal drop weight tests was +30°F, the Charpy v-notch tests for the base metal and the HAZ were performed initially at 900F. The base metal specimens did not meet the 1980 ASME Section III values for determining reference NDT at +90°F. However the HAZ energy absorbed and lateral expansion were far superior to the base metal properties, thereby meeting that requirement of the Code Case. The Charpy v-notch results for these tests are presented in Attachment 1 (6].

A second series of base metal and HAZ impact tests were performed at +1200F in an attempt to meet the Code of repair requirements at the maximum temperature allowed by the Code Case for the base metal. The results of these tests are presented in Attachment 1. The base metal tests again failed to meet the Code toughness requirements at the maximum temperature allowed by the Code Case. However, note that the HAZ impact toughness is still superior to the base metal toughness at 1200F, attesting to the adequacy of the weld procedure.

Conclusions

The properties of the base metal used in the temperbead qualification program did not meet all of the requirements of Code Case N-432 and the Code of repair. However, application of these requirements in this case is overly restrictive. The plant was constructed to ANSI Code B31.1 which prescribed much less in the way of notch toughness requirements for this material. The intent of Code Case N-432 is to assure that the weld procedure which is qualified, qualifies a process on representative material which provides assurance that the welding process has not degraded the base metal. The HAZ Charpy v-notch energy absorbed and lateral expansion were clearly greater than those of the unaffected base metal in this test program. The 7.125 inch thick SA302B plate used in this test program is representative material in that section thickness. One characteristic of this material is its poor through thickness hardenability, thereby ,-resulting in plate which in this thickness, may have poor notch

toughness in the 1/4t to 3/4t region. In reduced section thicknesses, this material is expected to have better toughness.

The steam generator shell at IP-2 is significantly thinner, 3.5 inches thick, and has superior Charpy v-notch impact properties compared to the test plate as would be expected for this grade of material. The steam generator shell impact strength exceeds the minimum construction code requirements of 30 ft-lbs at +10°F as contrasted to approximately 30 ft-lbs at 1200F for the 7.125 inch thick test plate. Were the test plate a more representative thickness, I believe that the notch impact properties would have been significantly improved. This observation is substantiated by the weld trial tests in the thinner plate (2.25 inches thick), where hardness measurements revealed a softened HAZ consistent with increased toughness for a representative material. The restrictions of Code Case N-432 required a thicker plate than is to be welded to in the field thereby restricting the qualification program to use of a base metal which could not be reasonably expected to meet the notch toughness requirements in the Code Case. Consequently, while all requirements of Code Case N-432 cannot be literally adhered to, I believe that, when considering both the trial weld tests and the procedure qualification tests taken 'together, a clear demonstration has been made that the HAZ properties have not been degraded in the SA302 B plate and that the temperbead process is technically qualified for use at IP-2.

I trust that this document meets your requirements regarding the qualification of this process. If you have additional questions, or require additional information, please do not hesitate to call.

Summary

Dr. Giannuzzi has been involved in solving materials and corrosion problems for the nuclear industry since 1969. One of the world's leading authorities on intergranular stress corrosion cracking of stainless steel in aqueous systems, Dr. Giannuzzi was employed by the Electric Power Research Institute in the Nuclear Systems and Materials Department for three and one-half years prior to joining Structural Integrity Associates in 1983. At EPRI, Dr. Giannuzzi was task leader and principal investigator involved in development and qualification of all the Boiling Water Reactor IGSCC piping remedies. This activity included primary responsibility for qualifying and producing material specification for the alternative materials (Types 316NG and 304NG stainless steels), qualifying the induction heating stress improvement (IHSI) remedy, qualifying heat sink welding, last pass heat sink welding and the weld overlay and performing the investigations to determine the causes of and remedies to IGSCC in Type 304 stainless steel pipe.

In addition to his BWR IGSCC responsibility at EPRI, Dr. Giannuzzi has had the lead responsibility for investigating the causes of low pressure large steam turbine stress corrosion cracking in nuclear and fossil steam turbines and has been involved in projects associated with bolt and fastener reliability, steam and water piping erosion-corrosion and has been active in projects related to primary and secondary side corrosion of steam generators. Dr. Giannuzzi has also been the lead project manager responsible for all

-materials related failure analysis activities in the Nuclear Systems and Materials Department and was a member of.the EPRI Three Mile Island Unit 2 task force.

Prior to his employment at EPRI, Dr. Giannuzzi was employed as a senior consultant at NUTECH. While at NUTECH, he formed the stress corrosion cracking group and developed the methodology used to estimate likely locations of IGSCC in stainless steel piping systems. He also was involved in the earliest investigations involving PWR boric acid corrosion and assisted in the final formulation of the NRC I-E Bulletin 79-02 which established criteria for inspection of the boric acid system piping.

From 1972 to 1978, Dr. Giannuzzi worked as a principal development engineer at the General Electric Company Nuclear .Energy Division. His responsibilities while at GE involved investigation of alternative materials and processes to alleviate the IGSCC problem in stainless steel piping. He managed the initial weld residual stress measurement and analyses activities which lead to the development of the residual stress remedies to IGSCC.

From 1969 to 1972, Dr. Giannuzzi worked for the Aerojet Nuclear Systems Company developing materials for use in the nuclear rocket engine (NERVA).

In 1983, Dr. Giannuzzi founded Structural Integrity Associates with Dr. P. C. Riccardella and Dr. T. L. Gerber. His activities at Structural Integrity have included nuclear plant life extension studies, temper bead weldinig development on low alloy steels and selecting of remedies to IGSCC in BWRs.

ossible Future Usage The properlies available through

, ,u ,IIU;e structures exhibiting these properties has awaited developments in procedures for welding and in procedures of control for assurance of required properties. ASME Code approval of the quenched and tempered materials to limited thick. nesses was 'given only after extensive testing was performed, involving not only tests of welded samples but also tests to destruction of relatively large vessels. Service experience of these materials has now been obtained with pressure vetisel and structural applications.

Lower alloy modifications of the materials have been proposed for use for the thinner thicknesses, heat treated to the same strength levels, to allow use of more economical materials. Conversely, the original alloy range has been proposed for usage at thicknesses greater than 2' 7 in. Requests for ASME Code approval of other low alloy steels up to various thickness levels have been made.

Several of the ASME Code materials presently used in the normal-

quenched" and tempered condition which would exhibit improved mechanical properties. Some of these materials would exhibit this improvement throughout thicknesses heavier than 2';: in. Most would exhibit variation in properties from center of thickness to surface. What are the maximum thicknesses which would exhibit improved properties throughout their thickness? What variations are exhibited? Is it possible to utilize any improved tensile properties in design?

There is a present need for large diameter vessels of an operating pressure which requires thickness of plates of present ASME Code materials heavier than the capabilities of mills to produce iwith sufficient degree of hot working; but which may be produced in usable thickneses and sizes with quenched and tempered materials. Although satisfying this need is not entirely limited by economics, the wider use of quencied and tempered materials may allow more economical finished products for other needs through

Both procedures may be applicable dependent upon the finished product. Both procedures, however. require close control of all the variables of the quenching process to the same extent as those applied by the material producer at his mill. For some designs, it may be advantageous to apply quenching to shapes prior to joining them by welding than to apply quenching to a completed vessel. Distortion due to heat treatment of shapes can be removed by cold or warm shaping. In either case, the weld metal must he specifically tailored for the applicable heat treatment of tempering only or quench and temper. Also in either case, the required properties must also be met in the heat-affected zone.

This sequence of events has resulted in a need for development of material procurement specifications specifically designed for quenched and tempered steels, heat treated

It aL , h.ls resul.ed in a need for further devlpmient of codes regulating safe '",islruition rules and procedures. [raditionally this has been a funclion of the American Society of Mechanival Engineers Boiler and Pressure Vesse'l Code and various Government agencies. All of these groups are active in this subject.

Development of high strength weld metal deposits has kept pace with quenched and tempered base metal development., What remains to be done for heavy thicknesses is to determine properties which ar' a-vatable and possible, to determin,, limits of controls necessary for n.suranre of these properties, and to polie purchase and fabrication such that these are obtained.

.Hardenability

/7 An approximation of the depth of hardening capabilities of various ImateriaLs can be obtained from the %work of M. A. Gro.ssmann.: The range of minimum and maximum hardenability calculated frrn the range of chemical analysis of *veral presently used and proposvd type pressure vessel steels is shown in Fig. 1. The chemical analyses and multiplying factors used in these calculations are given in Table 1 of the 'Appendix.

Design Presently approved ASME

quenched and tempered materials, as other Code materials, are assigned an allowable maximum design stress of i/, of their minimum ultimate tensile strength to a specified temperature limit. Where allowable stresses are assigned above this limit, they are progressively decreased dependent upon criteria based upon yield strength, stress rupture strength or creep strength at each temperature.

New design criteria, which conBider yield strength as well as tensile strength and which additionally consider su perimlosed service stresses such as thermagl stresses and low cycle fatigue and more rigorously define allowshle design details, are about to be lresented in a new ASME Code stction.

This requires a material capable. of meeting minimum design strength at the center of the thickness of the quenched and tempered single thickness material.

Cooling Rate The means available for cooling

from the auListenitizing temperature consist of air cooling, oil quenching and water or brine quenching. The quenchini can be acomplished by either a spray or by dipping in the quenching medium. Dip quenching should be (lone in a medium which is agitated to avoid vapor blanketing. Agitation can be accomplished by circulation of the medium by pumping or by agitation with air.

Literature data is available concerning cooling rates of various shapes and sizes of samples subject.ed to cooling in still air and various quenching methods:...

The pertinent variables involved \ in slprav and dip quenching are:

1. Austenitizing temperature and I ,me.

\ 2. 'rime from furnace to start of quench and temperature at start of qiench.

\.- 3. Surface condition of the metal degree of scale:.

\. 1. Volume of spray per unit time J or unit area per side and for dip

ai'lli'ation the ratio of quenching ,n..djum volume to metal volume.

jrkinew: ha:s been performed at 1A4..gh I niversity, on normalizing

and spray quenching cooling rates. Cooling rates obtained by dip

quenching of plates in agitated water and comparable cooling rates obtained by normalizing have been investigated. This has been done with various sizes and thicknesses of plates with thermocouples placed at the center of the thicknesw and at the' , thickness level at various locations in the plates. These locations varied from the center of the width and length to near the edges of the plates as indicated in photograph of Fig. 2.

Figure 3 shows the time required to reach a specific temperature during dip quenching at various distanms from the quenched edge for two heavy thicknesses of a range of thicknesses tested. This time becomes uniform at a distan rom the quenched edgeof---ap1 proxji 'rr elvz_ t gthe _plate_ thick..et. A test plate size of width and length of three times the plate thickness would exhibit a cooling rate at the center of its width, length and thickness approximating that of a larger production-size plate. A specimen of larger size than.2TY 3 would required, hoever, if any appreciabl.e volume of metal is required for re s.entatet ng samles. ''his is also dependent upon the hardenability characteristics of the material.

Figure 12 shows the strencti of A387B and A302B mat-erial(,,.de,: at rates shown in Figs. F and 10 respectively. It can be not,.d t i:at -. A387B material is not v-iliy strengthened by these co,,lini ri i's

but that the A302B matermi is. Figure 13 shows similar d ,La - r

Figs. 7 and 11 respectively. Here A212B shows no improvement. whereas 1204 material does and it retains its strength after tempering for 20 hr at temperatures of 1000 and 1100' Fand for5 hr at 1200' F but loses appreciable strength at 10 and 20 hr tempering at 1200' F.

Figure 14 shows similar data for A387D material cooled at rates shown ili Fig. 9. It exhibits an increase in strength on tempering at 1000 - F for up to 20 hr with strength rapidly decreasing after 10 hr or longer at 1100' F and 5 hr or longer at 1200" F. The maximum strength level exhibited, however, is higher than that exhibited by the Case 1204 or A302B material.

Figure 15 shows data for a 71, in. thick A387D dip quenched plate at the center of the thickness and at the I ', thickness level at the cooling rate of point 43 as shown in Fig. 9. Here, also. an increase in strength is exhibited at 1000' F temper for up to 20 hr. This high strength is retained up to 10 hr at 11000 Ftemper but drops below 140,000 psi tensile strength at the center of the thicki ss after 20 hr at 1100 " F. Further decrease is exhibited after only 1 hr at 12000 F. These properties, however, are quite high for such thick material.

analyses are available and will deposit sound weld metal exhibiting a variety of ranges of high strength tensile and impact properties in the as-welded and as-welded and tempered conditions. These can be chosen of various diameters and resultant operating amperages and used at selected travel speeds to regulate heat input to tolerances required for control of properties of the base metal heat-affected zone.

Multilayer gas metal-arc automatic processes are also available and require similar heat input control for maintenance of heat-affected zone properties. Flux cored wires and strips. are also available and usable for alloy additions. Multilayer submerged-arc processes, using bare electrode of the proper alloy content and. or alloy additions to the-flux or braided wires for regulation of the alloy content, either as a directly consumable electrode or as an additive to the molten pool, are also available. In all cases, however, the use of these processes for welding on steels previously quenched and tempered must observe proper heat input control to preserve the base metal heat-affected zone properties.I. '.. .:1.'. 1:14

Preheat and interpass temperatures must also be closely controlled -above a minimum to prevent cracking and below a maximum to prevent excessive loss of properties.

Material, which is to be welded in the annealed or normalized and tempered condition followed by quenching and tempering heat treatment of the welded part. requires an analysis of . weld metal, different from that above, which will develop properties equal to those of the base metal upon being subjected to quenching and tempering.

arc and electroslag or electrogas methods are usable for this type application.

Heavy thicknesses subjected to tempering or stress relieving heat treatments must be designed such that no welding is applied after the. final heat treatment, or such that welding is applied only to previously prepared attachment areas engineered so that the later applied aswelded attachment will not affect the integrity of the part. This necessitates careful design and selection of weld metal and attachment material with respect to ma-

terial strength and resistance to brittle fracture.

Service Criteria

Brittle Fracture Quenched and tempered materials

are advantageous not only for utilization of higher tensile properties but also for utilization of improved resistance to brittle fracture.'3-141 Whether such improved resistance to brittle fracture is necessary or not depends upon several factors. It may not be necessary for materials which operate warm, and which

High rebistance to brittle fracture may not be necessary for materials whichi are stress relieved and are adequately nondestructive tested to assure sufficient freedom from "crack starter" type discontinuities. The carbon steel and low alloy steels, of a low hardenability analysis not appreciably improved in tensile properties by quenching and tempering, are appreciably improved in impact properties in heavy thicknesses by accelerating cooling. only if they are melted to fine grain practice. Such deoxidation practice also minimizes deleterious effects from strain aging and quench aging.141

The range of Charpy V-notch properties of quenched and tempered plate of A212B and A302B materials and similar forging material analyses, tested in large production quantities, are shown in Fig. 16.

The more hardenable quenched and tempeied materials, however, generally show a greater degree of improvement in impact property values, although they also generally require higher impact values for equivalent degree of resistance to brittle fracture. The work of Pellini and Puzak and their colleagues, and Stout and his colleagues, has been particularly illuminating to this subject.

Temperature Limits The maximum temperature and

times at which quenched and tempered materials will retain their improved tensile properties is not known precisely. Design is generally based upon a factor of the yield strength at temperature, the tensile strength at tempelature, the stress rupture strength at temperature and the creep strength at temperature. The temperature at which each criteria becomes controlling must be determined for each material and condition. It is generally believed that, in the absence of such factors as temper embrittlement, the tensile properties are controlling up 'to possibly 700 or 800" F and that stress rupture and creep properties become controlling at above this temperature. At higher temperatures, the material will revert toward its normalized and tempered or annealed properties. Since most pressure vessels are designed for long life, on the order of 20 years or more, quenching and tempering

als and to allow application of the quenching and tempering at the fabricators shops. It also is awaiting the formulation of Code rules regulating safe construction pro. cedures.

Successful construction is dependent upon maintaining close control of material chemical analysis, heat treatment, welding procedure and all aspects of fabrication forming, heating and cooling. This requires closer control of techniques and procedures than those generally required for annealed and normalized and tempered material. This requires closer control in procedures of obtaining test samples for destru. tive testing which are representative of the larger mass of the prod urtion materials. Information which will be helpful in determining degree of control necessary in some oft hese aspects is given.

It is believed that the quality control assurances necesar. for proper application will cokint ul specific rules regulating and defining material procurement specifications, design aspects, and Iuihrici-

Appendix AL the cooling data were obtained from time-temperature traces

produced with an oscillograph recorder. Time zero was chosen as the moment just before immersion in the quenchant. Depending upon specimen size, chart speeds of 3 to 30 ipm were used. Recording ceased, when the center thickness of the plate reached 400: F.

The oscillograph recorder was initially calibrated with a millivoltage Source to establish a correlation between deflection and temperature. Subsequently, zero settings Were checked and adjusted, if necessary, prior to each cooling cycle. In all (-ss, 32' F was used as a reference Junction.

All thermocouples were of the standard -chromel-alumel type, insulated with ceramic beads and

w'lded to the test prlte as shown in Fig. 2. The tuhing plrevented water from 'ontacting the thermocouple junction and leads. Hot junctions were made by peening the wire into adjacent holes at the base of . 4 in. nominal diameter access holes. The above pro(edure exhibited satisfactory reliability.

Each test plate was grit blasted before entering the furnace. Heating time to austenitizing temperature was dependent upon the maximum rate of the furnace and a holding period was maintained until equilibrium was obtained.

All dip quenching was done in water agitated with air. Quenching was done in a water volume of either 69 or 131 cu ft. Air cooling consisted of suspending each piece in still air.

Figures 17, 18 and 19 show cooling rate data for the specific point numbers described in Table 2 and mnterial analyses described in Table 3. Cooling rate curves for other point numbers described in Tables 2 and 3 are shown in Figs. 7 through 11. Figures 20 and 21 show comparable cooling rate data obtained from the literature at various distances from the quenched end of Jominy test bars.

Figures 22 through 26 show thickness vs. average 'F per second cooling rate from 1750 to 400, 600, 1000, 1200 and 1400: F respectively.

Figures 27 through 31 show the same data plotted with relation to ratio of surface area to volume vs. cooling rate.

Attn: Mr. Steve Burkhalter

Subject:

CMS 405-89

Microhardness Testing of Various Welds Involved in Temper Bead Pass Welding.

Dear Steve:

At your request we have performed microhardness surveys through the HAZ of various weld samples that you had welded with different parameters in order to determine the required technique for proper temper bead welding of SA 302 grade A with ER 805-D2 filler metal. We used a Knoop indenter with a 500 gram load, observed at 200 x magnification, in locations A, B, C, and D as shown in the attached sketch.

In addition we performed microhardness surveys in locations A, B, and C on P-2 and P-6 single bead weldments in order to determine the highest hardness produced in the HAZ without tempering.

Photomacrographs and photomicrographs of the areas that you requested are enclosed.

Respectfully submitted,

William .Jo es III Consultin tallurgical Services

Relief Request 29

I. Request for Which Relief is Requested

(a) Name: Automatic Gas Tungsten Arc Welding (GTAW) Temperbead Process

(b) Function: Facilitate repairs involving welding on ASME Section III Class I Components

(c) ASME Section XI Code Case N-432, Repair Welding Using Automatic or Machine Gas Tungsten - Arc Welding (GTAW) Temperbead technique Section XI, Division 1.

2. Reference Code Requirements That Have Been Determined to be Impractical

The Code case weld procedure qualification required the test material be of the same specification type, grade, and class as the material to be repaired. Indian Point 2 steam generators were built to the requirements of ASME Section III 1965 edition including addenda through summer 1966. The steam generators were fabricated from ASME Section III SA 302 Grade B material which has an impact value requirement of 30 ft-lbs absorbed energy (N-330). The test specimen also used SA302 Grade B material and met the 1965 code edition of Section III impact requirement of 30 ft-lbs. However, the operative Section XI Code edition is 1980; the corresponding ASME Section I1 (1980 edition) imposes a 50 ft-lb requirement from which relief is requested. Achievement of this impact strength in a thick test piece is impractical.

3. Alternative proposal

It is proposed that Automatic Gas Tungsten Arc Welding (GTAW) Temperbead Process be accepted on the premise that the qualification procedure utilized test material whose properties correspond to the original code, ASME Section III, 1965 edition. Furthermore, the test results verify that the impact strength of the heat affected zone (HAZ) of the base metal is enhanced, as illustrated by the following test results:

Weld Metal HAZ Base Metal (400F) (90°F) (90°F)

Ft-lbs 83 44 32 Lateral exp 65 39 31

Material records on file indicate that the impact strength of the material actually used in steam generator construction corresponded to values ranging from 55 ft-lbs to 105 ft-lbs. Based on the test results, any repair using the GTAW method should result in improved values.

It is understood that the difficulties presented by Code Case N-432 are acknowledged by ASME personnel and that a Code change is currently under way incorporating the current proposed code modification for Shielded Metal Arc Welding (SMAW). The proposed changes in the code, as presently stated for SMAW, and as are to be proposed for GTAW, include:

o The test assembly shall be of the same P number and Group number as the component and will be post weld heat treated in a manner which is similar to the component (on the order of 80% of the heat treatment time at temperature).

o The Charpy-v-notch impact requirements of the test assembly shall meet the following:

- The base metal impact properties shall meet the design specification.

- The impact properties of the heat affected zone shall be taken at or below the lowest service temperature.

- The average of the three charpy-v-notch heat affected zone results shall be equal or greater than the average of the three base metal test results.

The results of the qualification process for the proposed GTAW in general meet these requirements.

4. Basis for Requesting Relief

Consolidated Edison has developed a temperbead weld qualification program for the Indian Point Unit No. 2 steam generator shell. The shell material is Section III SA302 Grade B low alloy steel, designated by the ASME Code as P-3 Group 3 material. The purpose of the temperbead qualification is advance preparation for performing a cavity weld repair to one or more of the IP-2 steam generator shells using this welding approach. ASME Code Case N-432, issued on February 1986, provided guidance for the temperbead qualification activity. Both weld parameter trial tests (on a thinner plate of section II SA302 Grade B material) and procedure qualification tests (on a thicker plate) were performed in order to select a weld procedure and then to qualify it. Although the thicker plate was not entirely representative in terms of toughness, the results on the thinner and thicker plates, taken together, demonstrate that the procedure is technically acceptable for use on the 3.5 inch thick steam generator shell at IP-2.

I

The properties of the base metal used in the temperbead qualification program did not meet all of the requirements of Code Case N-432 and the Code of repair. However, application of these requirements in this case would be overly restrictive and unnecessary. The plant was constructed to ASME Section 111, 1965 with addenda through 1966, a Code which prescribed less in the way of toughness requirements for this material than either the Code of repair or Code Case N-432. The intent of Code Case N-432 is to assure that the weld procedure is qualified as a process on representative material which provides assurance that the welding process will not degrade the base metal. The HAZ Charpy-v-notch energy absorbed and lateral expansion were clearly greater than those of the unaffected base metal in this test program. The 7.125 inch thick SA302B plate used in this test program is representative material in that section thickness. One characteristic of this material is its poor through thickness hardenability, thereby resulting in plate which, in this thickness, may have poor notch toughness in the 1/4t to 3/4t region. In reduced section thicknesses, this material is expected to have better toughness.

The steam generator shell at IP-2 is significantly thinner, 3.5 inches thick, and has superior Charpy-v-notch impact properties compared to the test plate, as would be expected for this grade of material. Were the test plate of a more representative thickness, it is believed that the notch impact properties would have been significantly improved. This observation is substantiated by the weld trial tests in the thinner plate, 2.25 inches thick, where hardness measurements revealed a softened HAZ consistent with increased toughness for a representative material. The restrictions of code Case N-432 required a thicker plate than is to be welded to in the field, thereby restricting the qualification program to use of a base metal which could not be reasonably expected to meet the notch toughness requirements in the Code Case. Consequently, while all requirements of Code Case N-432 could not be literally adhered to in this instance, the trial weld tests and the procedure qualification tests taken together demonstrate that the HAZ properties have not been degraded in the SA302 Grade B plate and that the temperbead process is technically qualified for use at IP-2.

Enclosed are records pertaining to the test plate.
