Director, Office of Nuclear Reactor Regulation Attention: Mr. George W. Knighton, Branch Chief

Licensing Branch No. 3 U.S. Nuclear Regulatory Commission Washington, DC 20555

Gentlemen:

Subject: Environmental Qualification of Post-LOCA Hydrogen Monitors Docket Nos. 50-361 and 50-362 San Onofre Nuclear Generating Station Units 2&3

On August 25, 1983, Mr. Hukam Garg of the NRC Equipment Qualification Branch contacted SCE regarding the post-LOCA hydrogen monitor environmental qualification package submitted on April 20, 1983. Responses were requested to six items resulting from the NRC's review of the package.

The purpose of this letter is to provide responses to the six items identified below. SCE believes that this submittal should satisfy any remaining concerns on the part of the NRC staff regarding post-LOCA hydrogen monitor environmental qualification.

Responses were requested to the following items:

Item 1

How was the hydrogen sensor qualified for chemical spray? Specifically, how does chemical spray affect the various materials in the hydrogen sensor?

Response

The chemical spray parameter is not applicable to the hydrogen sensor assembly. GE evaluated the sensor's material composition and determined that it was immune to the effects of chemical spray (see Attachment 1, telex dated August 22, 1978, from GE to BPC, log XB-21743, item NBR 4). Based on this analysis, caustic spray is not considered an applicable parameter for the sensor assembly.

8404050020 840402 PDR ADOCK 05000361 1 P UPDR

Mr. G. W. Knighton -2- April 2, 1984

Item 2

Provide a copy of the point specific radiation calculation.

Response

See Attachment 2. Note that as the transducer and sensor are located together, this calculation applies to both.

Item 3

Why was the seismic qualification test performed after the LOCA test?

Response

The applicable test report, GE Report 80SDS4244, para. 3.2, responds to this question. It is provided as Attachment 3. Note that such a change to the IEEE 323-1974 test sequence is allowed by section 6.3.2 of the standard which states "the sequence used shall be justified as the most severe for the item being tested."

Item 4

Explain how the post-LOCA qualification was extrapolated from 90 days to 120 days.

Response

See Attachment 4.

Item 5

For aging, how was the activation analysis extrapolated in the arrhenius calculation?

Response

Since the sensor assembly is only qualified for two years, it is considered that it will not age during that brief of a period, therefore, thermal aging was not considered applicable. Attachment 4 describes the post-LOCA aging evaluation.

Item 6

Provide documentation to demonstrate the pressure sensor in the monitor is qualified for 40 years.

Response

Appendix I of GE Report 80SDS4244 (Attachment 5) evaluates the pressure transducer materials of construction, and determined they were not susceptible to age-related degradation. Therefore, the assembly is inherently thermally qualified for 40 years. The transducer was tested to a total integrated dose of 3.2 x 107 rads (Attachment 6) and has only a total integrated dose requirement of 2.55 x 107 rads. The total integrated dose includes both a 40-year normal dose, a LOCA dose, and a 120-day post-LOCA dose. Therefore,

Mr. G. W. Knighton -3- April 2, 1984

the transducer is radiation qualified for 40 years. These two parameters (thermal and radiation aging) are the only two aging criteria applicable to the transducer assembly. Therefore, it is considered qualified for 40 years.

If you have any questions or comments, please contact me.

Sincerely,

Enclosures

TU primary Containment Hydrogen Monitoring System utilizes a hydrogen partial pressure

sensOr in conjunction with a total pressure sensor and appropriate electronic components to

dcate the percent of hydrogen present in the primary containment atmosphere.

2.2 SENSOR ASSEMBLY

The hydrogen partial pressure sensor is galvanic in nature and consists of a platinum black

electrode and platinum oxide counter electrode within a polysulfone housing. Figure 5

is a schematic of the sensor configuration. The electrolyte providing the ion conductive

path between the two electrodes is separated from the ambient atmosphere by a gas

permeable membrane which is in contact with the sensing electrode. When. the ambient

atmosphere contains hydrogen an electrical current is generated by the sensor which is

directly proportional to the partial pressuj; of the hydrogen in the atmosphere.

Test sequence recommended in IEEE 323-74 is:

Pretest Visual Inspection Baseline Functional Test Radiation Exposure Functional Test Aging Functional Test Seismic Qualification Functional Test LOCA Environment

Justifications of variations of the test sequence conducted and those listed above are:

Radiation: Radiation was done in two steps, half before LOCA and half after LOCA followed by a performance test and seismic test. This has three advantages over doing the entire radiation before LOCA simulation:

1. It more accurately simulates the actual condition where the radiation will occur before and after the maximum temperature and pressure extremes.

2. In exposing the sensor to radiation after the stresses of temperature and pressure, any unanticipated synergistic effects of the three stresses are more likely to be identified.

3. By dividing the radiation testing and making a performance measurement after each radiation exposure, any performance degradation trends could be identified. These would be useful in predicting end of life. No degradation due to radiation was detected at after either radiation exposure.

Aging: Because of the limited life of the sensor, aging is not an essential-step in the qualification testing. Appendix K provides further data on sensor aging.

The pressure transducer aging is described in Appendix I.

LOCA Before Seismic: The.H 2 Sensor is a simple device stable in structure and unlikely to be affected by the levels specified for a seismic event. It would be in a most susceptible condition for seismic damage after a LOCA type maximum temperature excursion. Therefore, the seismic testing was conducted post LOCA with subsequent performance testing and inspection.

sequence. Operability during the remaining 90 days of post-DBA operation

can be demonstrated through use of the Arrhenius equation and taking credit

for the remaining 60 days of test data.

The Arrhenius equation is used to establish a time equivalency between two

data points using the activation energy of the age-susceptible material.

Since the two data points are defined (required operation of 90 days at

120 F, test operation of 60 days at 200 F), solving the Arrhenius equation

yields a required activation energy of only 0.092 ev in order to establish

a time equivalency between the two data points. 0.092 ev is essentially a

negligible requirement since most materials have activation energies from

0.6 to 1.3 ev, therefore, an age equivalency between the two data points

is established.

Attachment " Page -L '-I

As demonstrated pages 3 and"L) the SONGS 2 and 3 temperature

and pressure design envelope curves provide some margin over the actual tem

perature and pressure transients for the worst case LOCA scenario.

On pages I and q of this Attachment, the actual test curve, as described in

is superimposed on both the design envelope and actual transient

curves (for both temperature and pressure) in order to graphically demonstrate

the available margin for these parameters.

ACCELERATED LIFE TEST REPORT - CEC-1000 PRESSURE TRANSDUCER

INFORMATION REQUESTED/RELEASED

The aging procedure defined in PIR 1B90-CAMS-205 was completed on CEC Pressure Transducer

Part Number 1000-173, S/N 4240.

RESULTS

* Overall worse case change in performance occurred at 350*F and was a zero shift

of -. 413% of Full Scale. * Unit aging is unnecessary since pressure transducer contains

no age sensitive materials.

* Aging test served to increase confidence in component reliability.

SPECIMEN

The specimen included CEC Transducer S/N 4240, (see Attachment 1) mating connector P/N 170200

and -50 feet of cable fabricated from Raychem Spec. 44 twisted shielded pair.

DISCUSSION

Log of key test activity is summarized in Table 1 and followed by a brief description of

each.

0 0 Pre and Post Performance Tests

Both tests were performed at CEC to the 1000-04 (173) Acceptance Test Procedure dated 7/7/77 modified to include the linearity and hysteresis run at 250*F. Results were excellent with maximum deviation occurring at 350*F as a zero shift of -.413% of full range relative to the 4/9/79 test. The CEC calibration data summary is included with this report as Attachment 2.

Accelerated Life Environment, PIR 1B90-CAMS-205

To verify the long term operation requirements, the pressure transducer was subjected to the procedure presented in Attachment 3. The aging of the pressure transducer was performed by using present state-of-the-art aging technology. This technology allows acceleration of the time/temperature aging effects artificially by increasing the temperature. The pressure transducer contains both metallic and non-metallic components. The deterioration due to aging effects on the metallic components is judged to be insignificant. The aging of the pressure transducer was therefore based on its non-metallic materials only.

It is known for many non-metallic materials, that the degradation process can be defined by a single temperature-dependent reaction that follows the Arrhenius equation:

Ea - kBT

k = Ae (1)

where,

k = reaction rate

A = frequency factor

Ea = activation energy

kB = Boltzmann's Constant (8.617 x 10-5 eV/*K)

T = absolute temperature

1-2

PIR 1B50-CAMS-235 PAGE 3

It is further noted that, for many reactions, the activation energy can be considered to be constant over the applicable temperature range. Equation (1) can be transformed into a form which yields an acceleration factor to define a given amount of thermal degradation. The form is:

T (T T2 (2) *tl/t2 * e

where,

t1 accelerated aging time at temperature T1

t2 - normal service time at temperature T2

Ti - accelerated temperature T1 (OK)

T2 = normal service temperature T2 (oK)

Equation (2) can be used to derive the accelerated aging times for materials with known activation energies.

Normal operating temperature for the transducer is 1200F. The transducer was operated for 14 days at 300*F as presented in Table 2. From equation (2), this would age to greater than 40 years any material with an activation energy less than .81 eV. This would include most organic materials.

Aging Analysis

Table 3 describes the non-metallics in the pressure transducer. Both materials are included in the following list of materials that are considered to not have significant aging characteristics:

Silicon semi-conductors, resistors; tantalum dry electrolytic capacitors; ceramic capacitors; dry paper and plastic film capacitors; mica capacitors; glass capacitors; integrated micro-electronic devices; hybrid micro-circuits; steel, aluminum, copper, epoxy fiberglass GI1, Gl, or equivalent; brass, ceramic, and glass-filled diallylphthalate.

Since there are no age sensitive materials in the transducer, no aging prior to seismic is required. The temperature aging test serves as a confidence test in the pressure transducer reliability. A detailed "aging" test log is presented in Table 2.

No detectable change observed in unit performance or visual appearance.

Available in many standard ranges from 15 to 10,000 psi, the CEC 1000 Series also feature an innovative double-case

* Rugged Dual COse Isolation isolation. The basic sputtered sensor is electron beam welded to the pressure chamber/adapter which also provides a high degree of mechanical isolation from mounting torque effects. The sputtered sensor is well isolated from external case effects since the case is welded to the pressure chamber/adapter and not in contact with any portion of the sensor.

CEC Sputtered Gage Pressure Transducers are manufactured in accordance with the program quality requirements of MIL*Q-9858A.

For further information about this pressure transducer, or special application designs, contact the nearest Bell & Howell/CEC Division Sales Office or factory in Pasadena. California.

Dear Mr. Collery:

This will summarize parameters pertinent to the irradiation of CEC XDUCER, calibration cap and cylinder, as per your purchase order A28-A10311, dated August 28, 1979.

The specimens were exposed for 37 hours at-an average dose rate of 1.0 Megarads per hour, yielding a dose of 37 Megarads. The. specimens were over-irradiated to account for the t3% accuracy of the the dosimetry system; the reported dose is 32.Megarads.

Halfway through the exposure, the specimens were rotated 1:800 to give a more uniform dose distribution.

Dosimetry was performed using Harwell Red 4034 Perspex dosimeters, utilizing a Bausch and Lomb Model .710 spectrophotometer as the readout instrument. This system is calibrated directly with NBS, with the last. calibration being May 30, 1979.. A copy of the dosimetry correlation report is available upon request.

Irradiation was conducted in air at ambient temperature and pressure. Radiant heat from the source heated the samples somewhat, but the temperature did not exceed 1300F, as indicated by previous measurements on an oil solution in the same relative position.

Irradiation.was initiated on August 31, 1979, and was completed on September 2, 1979.

. Sincerely yours,

ISOMEDIX, INC.

Chemical spray was not included in the LOCA testing because the exposed materials are the same as those used in Oxygen Sensors which contains a much stronger basic solution of 50% KOH.

3.3 SUPPLEMENTARY TESTS

1. Top Assembly Seismic Test - This test was performed to demonstrate the H2 Containment Atmosphere Monitoring System ability to withstand simulated seismic vibration. Note that all analyzer components described in Paragraph 1.3.4 were included. Detailed test results are presented in Appendix F.

2. Pressure Transducer Tests - The pressure transducer underwent an aging test to demonstrate long term operation. The environment included elevated temperature of 300*F and a radiation exposure of 3.2 x 107 Rads TID. Detailed description of the test and results are presented in Appendix I.

The transducer was not subjected to a separate LOCA pressure and temperature profile. The CEC predelivery test environment, Appendix G, exceeds the maximum predicted LOCA conditions for temperature and pressure. The testing in Appendix I includes 14 days of continuous operation above 300*F and 48 PSIA. In addition, the acceptance test on the pressure transducer (Appendix G) includes short term testing at 400*F and two times rated pressure (200 PSI). These combined conditions stress the pressure transducer far beyond the conditions of the SONG 2 and 3 LOCA profile.
