AUDIT OF THE ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT AT THE SUSOUEHANNA STEAM ELECTRIC STATION

1.0 INTRODUCTION

On May 3-7, 1982, a team comprised of representatives of the Reliability and Statistics Branch of EG&G Ioaho, Inc. and NRC staff conducted an audit of the environmental qualification of safety related electrical equipment at the Susquehanna Steam Electric Station. The work effort consisted of:

(1) a pre-audit review of the licensee's submittal (Ref.1), (2) an audit of the licensee's central files for selected equipment items, and (3) an onsite visual inspection of tne equipment items for which the central files were audited. Qualification deficiencies for individual equipment items are provided in Appendix A.

Summaries of the central file reviews are provided in Appendix B.

2.0 EVALUATION General concerns and comments resulting from both the audit and the pre-auait review of the SSES submittal are as follows:

(1) Due to the obvious intensive effort by the applicant, many minor errors were noted, particularly in the various lists and SCEW sneets.

These should be corrected.

l (2) The maintenance and surveillance program, which was still ir.

development, needed improvement in the following areas:

(a) Any waiver on scheduled equipment qualification related main-tenance must have the approval of the engineering department, i

with analysis of effects on equipment qualification and e

I justification for any waiver.

l 1

1 L

(b) The identical process should be followed if nonidentical replacement parts are considered for use, i.e., changes in gasket types or vendors, changes in lubricants, etc.

(c) Procedures should be initiated to allow engineering analysis of trend data accumulated during preventive maintenance, scheduled calibrations, and scheduled surveillance.

(3) Components whose qualified lives are less than 40 years, and those needing periodic replacement of parts to attain a 40 year qualified life should have notes added specifying replacement intervals, future qualification plans, or a plan of action.

Where replacement is scheduled, the qualified replacement should be identifiea.

(4)

Testing is listed under qualification method in some cases, with-out the type of test, (i.e. sequential test, simultaneous test, etc.) being noted. This shoulu be corrected.

3.0 CONCLUSION

S As a result of the audit it was concluded that SSES has demonstrated a high level of effort toward the E.Q. program. When SSES resolves the concerns noted above, their programs should be complete and in accordance with NUREG-0588.

APPENDIX B SUMMARIES OF SSES CENTRAL FILE REVIEWS

,loni/ation Chamber: General E lectric Model No. NA05 237X731G001 0

The ionization chambers are located in tne concrete wall of the steam tunnel.

Thej are used to detect abnormal radiation in the main steam lines.

The specified accioent erivironmental parameters are as follows:

Temperature, 130 F, Pressure,

.005 PSIG, Humidity, 100%, Radiation 6

1.9 x 10 Rads TID, and operating time, < l second.

The chamber nas been qualified to environmental parameters which exceeo those listed above by adequate margin by testing (GE Design Memo. 2.1/, October 4, 1972), analysis, and Peach Bottom operating experience.

The parameters are; Temperature, 160 F Ly test and experience, Pressure, 284 psig by test, Humidity, 100% by analysis, Radiation, 1.0 x 10 Rads TID by analysis and experience, and Operating Time, one hour by analysis.

The qualified life claimed is five years which will be extended to 40 years by type testing in conjunction with LaSalle.

It is concludeo that the General Electric Ionization chambers are environmentally qualified for tive years and that evidence ot qualification is provided in the applicants files.

Solenoid Valve: ASCO Model No. HT 8323A22 The valve is located in the reactor building and is used to isolate the scram discharge volume piping, The specified acciaent environmental parameters are as follows:

Temperature, 104 F, Pressure, atmos., Humidity, 90%, Radiation, 3

9.3 x 10, Raos TID, and Operating Time,10 minutes.

17

The valve nas been qualified to environmental parameters which exceed those listed above bv adequate margin by testing (GA Report, Gulf-GA-Al205, Mdy 30, 1972) and by analysis. The parameters are: Temperature, 330 F, Humidity, 100%, and Operating Time, <70 minutes; all by testing.

Radiatinn is 2 x 10 Rads, by analysis.

The qualified life claimed is 40 years provided the solenoid valve is rebuilt every 7 years, s

!L is concluded that the ASCO Solenoid valve is environmentally qualified and that evidence of qualification is provided in the applicants files.

Pressure Switch:

Stat.c "0" Ring Model No. 12N-AA4-X10TT 145C30ll These pressure switches are used to provice high drywell pressure signals and are located in the reactor building.

The specified accident environmental parameters are as follows:

Temperature, 104 F, Pressure,.25" WG, Humidity, 100%, Radiation 6

3.5 x 10 Rads TID, and Operating Time, <l hour.

Environmental testing of this type pressure switch is recorded in Viking Test Labs Report 30203-2 (G.E. DRF #A00-1084, index 38), 11-20-73.

A sunimary of this test report is included in the applicants files. The maximum environmental parameters that the switch was subjected to are as follows:

Temperature, 212 F, Pressure, 7" WG, and Humidity, 100%. The test duration was six hours. Radiation was not addressed in the test; 6

however,the applicant has qualified the switch to 3.85 x 10 Rads TID by analysis. Trie triargins for all parameters are considered acequate. The qualit ied life established is 40 years provided that a maintenance schedule is followed. This scheoule is based an analysis of noametalic parts.

It is concluded that the Static "0" Ring pressure switches are environmentally qualified and that evidence of qualification is provided in the applicants files.

18

Actuator Damper:

ITT General Control, Model No. NH-90 Series Used for damper control in the Reactor Building HVAC System and the Standby Gas Treatment System.

The specified accident environmental parameters are as follows:

5 Temperature, 104 F, Pressure, atmospheric, Humidity, 100%, Radiation 6

7.57 x 10 Rads TID, and Operating Time, intermittant use for 100 days.

Environmental testing of a similar unit is recorded in ITT General Control Report #721.77.095 (with Addendum #5). The maximum environmental parameters to which the unit was subjected to are as follows: Temperature 7

212 F, Pressure, 9" WG, Humidity, 100%, Radiation, 2.3 x 10 Rads TID, Test duration, 31 days. The testing envelopes the accident with adequate margin. Aging for three months @ 140 C yielded a qualified life of 40 years with recommended maintenance.

It is concluded that the Actuator Damper is environmentally qualified and that evidence of qualification is provided in the applicants files.

radiation aging and no thermal or radiation aging was performed. A gamma heating analysis inaicates that the highest temperature reached inside the detector during a LOCA is 460 F and the nearest heat sensitive material is the Raychem splices over the connectors attaching the Rockbestos cable to the " pigtails" coming out of the detector. The Raychem splices are qualified to 400 F and it is concluded that the temperature at that distance from the detector centerline will not reach 400 F.
