SUSQUEHANNA STEAM ELECTRIC STATIONNSSS EQUIPMENT FATIGUE EVALUATION-SUPPLEMENTARY DATALICENSE CONDITION (23)(a) AND SER ITEM 3.10.1(3)ER 100450 FILE 148-01PLA-1698

Reference: 1) PLA-1222, dated 7/29/82 from N. W. Curtis to A. Schwencer

Dear Mr. Schwencer:

This letter and its attachments contain the data requested by the NRC tosupplement our response (Reference,l) to your concerns regarding the fatiguecycling effects on NSSS equipment due to SRV loads (License Condition 23(a)and SER Item 3.10.1(3)) .

1.0 Number of SRV Events for BWR-4 Reactors

Derivation of the HPCI turbine fatigue test requirements indicatedthat 900 SRV actuations were appropriate for equipment fatigue designin BWR-4 plants. This value is based on empirical data from theoperation of Browns Ferry and Peach Bottom.

Based on observed response time histories of components due to SRV

loads, two (2) significant peak load cycles on equipment outsidecontainment and four (4) significant peak load cycles on equipmentinside containment can be expected for one (1) SRV actuation.Consequently, the number of peak load cycles due to SRV actuationspostulated for the 40 years of plant operation is 3600 for equipmentinside containment and 1800 for equipment outside containment.Observing that the significant load cycles from an SRV dischargeoccur within the first half second of the event, the fatigue agingrequired time in a response spectrum test is approximately 450 seconds(7.5 minutes) .

2.0 E ui ment Fati ue Anal sis and Testin — Su lementa Information

The following information is provided as a quantitative backup todemonstrate that the SRV fatigue aging requirement of Paragraph 1.0 ismet for'he equipment previously identified in Reference 1.

2.1 ~anal sls:

Fatigue analyses were performed for the five components listed insection 1 of Reference l. Based on an environment with 1800 significantstress cycles (as explained above for equipment outside containment),the maximum usage factor (or cumulative damage factor) was 0.33 whichoccurred on the RCIC pump holddown bolts (5500 cycles allowed for thecalculated fatigue stress) . The calculations are contained withinAttachment l.

2.2 Test:

Supportive data is given below for equipment whose fatigue lifeadequacy was demonstrated using methods of extended duration testing.

2.2.1 MSIV-LCS Blower (E32-C001/C002)

Extended duration testing was performed on the blower. The total testtime was 40 minutes and was achieved as follows:

a) 4 Upset Condition Tests (OBE + SRV) for 5 minutes each at 2g'sinput.

b) 4 Faulted Condition Tests (SSE + SRV + LOCA) for 5 minutes eachat 3g's input.

These g-levels are far in excess of the O.llg ZPA of the required SRV

spectra. See the SQRT form in Attachment 2. For the sine sweep testmethod which was performed in the range of 3.8 to 33 hertz, severalthousand cycles minimum per each 5 minute test was imposed on the testspecimen such that the cumulative number of cycles greatly exceededthe required 3,600 cycles from Section 1.0. Neither structural noroperability failure occurred during this testing.

2.2.2 Electrical Cabinets

Additional extended duration testing of the cabinets with mounteddevices was performed to demonstrate fatigue life adequacy of thisequipment. Test programs and results are described below.

2.2.2.1 4.16KV Switchgear

The extended duration test is verified on- pages 2 and 3 of the SQRT

form in Attachment. 3. A biaxial sine sweep test covering the ampli-fied portions of the SRV spectrum (4 to 70 Hz) was performed inboth the side-to-side/vertical and front-to-back/vertical orienta-tions in the single cell configuration and in the front-to-back/

@i

1I ~

V



vertical orientation only for the multiple cell configuration. TheSRV fatigue tests were performed by sweeping up and down at a sweeprate of one octave per minute for 30 minutes. The input accelerationlevel was approximately 0.08 g. This sinusoidal input level wouldproduce a spectral acceleration level of approximately 2 g at 2%

damping, which is well above the SRV + LOCA levels of approximately0.9 g.

2.2.2.2 125 VDC Power Distribution Panel

Upon completion of the first combined load qualification test, SRV

fatigue tests were performed using multi-frequency biaxial motion(XY and ZY). Each test was run for 60 minutes by repeating the testtable input motion which had a TRS enveloping the required SRV RRS.

Enveloping was checked at the beginning, middle, and end of eachtest. Refer to the SQRT form and spectra in Attachment 4.

2.2.2.3 Power Ran e Monitorin Cabinet

Qualification, testing of this NSSS cabinet was completed in the weekof March 27, 1983. Successful fatigue cycling tests were performedusing two biaxial time history motions (HGV) for 15 minutes in eachplane. The input waveforms had a TRS designed to envelope thefollowing RRS.

The test plan and panel RRS .were determined to be adequate forSusquehanna prior to the test.

2.2.3 Valve Motor 0 erators

Extended duration testing was conducted during dynamic qualificationof Limitorque motor operators as follows.

Fatigue was not considered a concern for the metal parts of theactuator due to the low stresses involved. The critical parts are theplastic parts, limit switch rotors, limit switch finger base andtorque switch. For the unit selected, an SMB-2-60, the orientationmost severe for fatigue is the vertical direction. Therefore the testwas done only in the vertical direction. The g loading of 3g was aconservative load based on the fact that the actual SRV-only loads areless than 3g.

~ l ~ lI

JUN,O g ]9,8BPage 4 SSES PLA-1699


The test excitation was in the form of a sine sweep from 10 to 70 to10 hertz at a sweep rate of one octave per minute which imposedapproximately 30,000 cycles on the operator. These load cycles aresignificant regardless of frequency because the operator fundamentalfrequency was previously found to be in excess of- 100 hertz. The testunit was operated after this testing.

2.2.4 MSIV Actuator

The referenced letter describes that credit was taken for additionaltesting to cover SRV fatigue cycling on the actuator.

Since the required vertical input motion to the inclined actuator isapproximately an order to magnitude greater than the horizontalcomponent, it, dominates the critical stress in the yoke rods. Repeatingthis input after horizontal rotation of the test specimen for each

upset'nd

faulted condition test, therefore, results in twice as many yoke rodstress cycles than will occur on the SSES MSIV actuator for the designcondition of five upset and one faulted-condition load events. Thehorizontal and vertical upset and faulted RRS and TRS for the actuatorare shown in Attachment 5.

Therefore, credit for SRV aging is taken for 5 upset tests and 1

faulted test. Since an upset test is equivalent to 60 SRV events whilea faulted test is equivalent to 50 SRV events, this additional qualifi-cation testing is equivalent to 350 SRV events.

Further testing run on the test specimen is equivalent to another 390SRV events as shown below, giving a total of 740 equivalent SRV eventsproduced by the testing.

120 SRV events120 SRV events100,SRV events

50 SRV events390 Total

In regard to test levels, the MSIV upper mass g-level calculated inthe piping analysis was approximately 9 g's using an SRSS combination.With an actuator fundamental frequency of 10 hz, the full levelfaulted testing subjected this mass to more than twice this value asshown by the TRS in the attachment, and this was verified by theaccelerometer records.

Therefore, the above-reduced level tests are sufficient to cover SRV

excitation while the higher g-levels associated with the qualificationtests can be considered equivalent to additional SRV stress cycles ona fatigue usage factor basis, concluding that the required number of900 SRV events were met by the testing.

2.2.5 CRD Vent and Drain Valves

SRV fatigue cycling will be part of the upcoming dynamic, qualificationtest on the SSES CRD vent and drain valves. The current test plancalls for horizontal and vertical time history waveforms simultaneouslyinput to the test table for a cumulative time of 15 minutes. Thistest will be repeated after a 90 degree rotation of the test specimen.The TRS will envelope the following generic RRS during testing ofthe later model valves in SSES Unit 2:

higher~ength irons, stress con-~tration factors associated Trlthchanges of shape in the past are im-

rtant for torque loads~ well asor bending and tension loads.Isodulus of ElasQcity. Typical

stress-szrain curves for gray ironare shown in Fig. 10. Gray iron doesnot obey HooRe's law and the znodu-hls in Sentdon ls usually dctermiztedarbitrarQy as the slope of the lineconnecting the regin of the s~-strain curve with the point corre-sponding to 4 of the tensQCstrength. Some engineers uac'-theslope of the stress-strtLin curve nearthe origin for determining themodulus of elftsticity.

As indicated in Table 12, the mod-ulus of gray iron varies considerablymore than for most metals. Thus, inutdng observed strain to calculatestress, it is esaen(ial to measure themodulus of the particular gray ironspecimen being considered. The nu-merical value of the modulus intorsion is always less thrn in ten-(don. lusl as it ls fo. SteeL

Hardness of gzay iron, as meas-ured by BrincQ or RocRwcll tcsters,is an aveztage result of the softgraphite in the izon and the metallicmatrix. Vttriations in graphite ldseand distribution wQ) cause wide var-iations in hardnesa (particularlyBocRsoell hardness) even thoughthe hardness of the metallic matrixis constant. To Qlustrnte this effect,the miczohardncss of the matrix offive types of hardened iron, as com-pared with ItocRwcll C measure-ments on the same iron, is shown inTable 13.

It is apparent that ifany hardnesscorrelation is to be tsttempted, thegraphite must be constant as to typeand amount in the irons being com-pared. It is recommended that Brin-ell hardness be used when possible.

Fatigue Limit in ReversedIleftding

Because fatigue limits are expen-sive to determine, the designer usu-ally has incomplete information onthis property. Typical 8-N curves for

gray iron under completely reversedcycles of bending stress are thotrnin the graph on left in Fl . 11, tnwhich each point represents thedata from one spcclznen. The cffc:tsof temperature on fatigue liznlt andtensQe strength are shown in thcright-hand graph in Fig. 11.

, Axial loading or torsional ]~~cycles are frequently encountered ia "

.

designiug pazts of cast iron, and lnmany instances these are not cout-pletely reversed loads. Types of reg-ularly repeated sees'ariatlon ustt-ally can be expressed as a functionof a mean stress and a stress range.

'rlhereverpc+sible thc designershould use actual data from thc 1Ln-ited information avaQable. Wllhotttprecisely applicable test data, an es.timate of the reversed bcndiagfatigue limitof machined parts tnaybe made by utdng about SS% of thcminimum specif)ed tensQc szrtngaof the paMcular grade of gray izoabeing coruddered. This is probably sas.fe value rather than an averageof the few data avaQable concerningthe fatigue limit for gray iron.
