AUDIT OF THE ENVIRONMENTAL QUALIFICATION OF SAFETY-RELATED ELECTRICAL EQUIPMENT AT THE GRAND GULF NUCLEAR STATION, UNIT 1

~

1.0 INTRODUCTION

On October 19-22, 1981 a team comprised of representatives of the

, Reliability and Statistics Branch of EG&G Idaho, Inc. and Nuclear Regulatory Commission Staff conducted an audit of the environmental qualification of safety-related electrical equipment at the Grand Gulf Nuclear Station Unit 1. The work effort consisted of: (1) a pre-audit review of the licensee's submittal, (2) an audit of the licensee's central files for selected equipment items, and (3) a visual inspection of the equipment items for which the central files were audited. Qualification deficiences for individual equipment items are provided in Appendix A.

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

2.0 EVALUATION General areas of concern which remain as a result of both the audit and the pre-audit review are as follows:

1. A more detailed justification for interim operation needs to be provided for some equipment items.

2. Electrical interfaces such as splices, terminal blocks, and terminal boxes were not included in the submittal. These items should be included and qualified.

3. Radiation doses for the drywell areas appeared to be low. These values should be justified.

3.0 CONCLUSION

S As a result of the audit it was concluded that the Grand Gulf environmental qualification program was adequate and that the fourteen individual files reviewed were complete. The licensee agreed to respond to the remaining areas of concern.

APPENDIX B SUMMARIES OF CENTRAL FILE REVIEWS Item: Samuel Moore & Co. Instrument and Computer Cable Model: Dekorad ID: QSR32T004H The cable is located throughout the plant except in Room 1A105. The harsh environmental parameters specified are-30 psig; Humidity,100%; Radiation 4.21 x 10 I ads gamma, 1. Temperature, 330*F;3 Pre R Rads neutron equivalent gama, and 1.5 x 109 Beta; Spray 1gpm/ftgx10 for 12 days. The tested cable was exposed to: Temperature 340*; pressure, 103 psig; radiation 2 x 108 Rad, chemical spray .15 gpm/ft. No specific failure criteria were stated for the testing on the cable,:the analysis given by G.G. was that the cable did not have a loss of function and it held the applied voltage with no insulation failure, also the applied test potentials were many times larger that what would be applied during opera-tion. It is concluded that this cable meets the requirements of NUREG-0588.

Item: Rockbestos Multi-Conductor Control Cable Model: Firewall III ID: QSR35T007B The cable is located throughout the plant except in room 1A105. The harsh environmental parameters specified are: Pressure, 7 Temperature Rad y , 1 4 330*g; x 10 Rad 44.7 psig;equiyalent neutron Humidity,100%;

y , 1.5 Radfation 4.21 x 10 Rad 8, x 1018.8 lbm/ft $ for 5 sec Froth and I gpm/ftz spray for 12 days. The tested cable was exposed to; temper-ature, 346*F; pressure,113 psig; radiation 2.2 x 10 8 Rad y , RH,100%.

The cable in the plant is multiconductor but the tested cable was single conductor, also the test was ran for only 30 days instead of 100 days. The analysis given by GG for these items was adequate. It , concluded that the cable meets the requirements of NUREG-0588.

Item: Raychem, Speciality Cable; Coax. and Triax.

Model: Flamtrol ID: QSRT00lH This cable is located throughout the plant except in room 1A105. The harsh environmental parameters specified are: Temperaturg, 330*F; Pres-sure, 44.7 psig; Humidity,100%; and Radiation, 4.21 x 10' Rad. During testing the cable was exposed to the following environmental parameters; l temperature, 357'F; pressure, >70 psig; radiation, 2 x 108 Rad. Rela-tive humidity steam. The cable jacket shields the cable from Beta radia-tion. The GG submittal stated that the cable could be submerged for 100 days, but GG clarified this by stating that for any equipment that is required to operate after submergence, its cable is submerged for 10 sec or less, and any equipment that has cable submerged for >30 sec is not required to operate therefore the 14 day submergence of the tested cable is adequate. It is concluded that the cable meets the requirements of NUREG-0588.

Item: Raymond Control Systems Automatic Dumper Actuator Model: MAR-49-30-4 ID: Q1T48F0018 The audited actuator is located in Room 1A527. The harsh environmental parameters specLfied are: Temperature, 80*F; Pressure, atmospheric; Radic-tion, 2.88 x 10^ Rad; and Humidity, 50%. The tested actuator was exposed ,

to; temperature 264'F for 57 days; pressure,14.7 psig; radiation, 2.88 x 104 Rad; Humidity, 95%. There were some failures during the aging '

portion of the test. The lubricant was replaced by Exxon Beacon 325 hi temp grease and plastic cams were replaced by aluminum cams. The actuator has a maintenance schedule for replacement of parts. All age suseptable i parts will be changed out at least every 20 yrs and more often on some parts. Using the Arrhenius method a QL of 23.6 years at 120*F was calcu-lated for the actuator. It is concluded that the actuator meets the requirements of NUREG-0588.

Item: Electronic Signal Isolating Device Model: 70-0Cll ID: lH22-P502-1 The optical isolators are used to isolate class lE circuits from non class lE circuits. The harsh environmental pargmeters are specifed as temperature (140*F max) and radiation (5.3 x 103 RadsTID). The speci-fled operating time is 100 days. Review of the environmental qualification documentation indicated that a similar unit had been exposed to environmen-

-tal conditions which exceeded those listed above by adequate margin. It is concluded that the optical isolators meet the requirements of NUREG-0588.

Item: MSIV LCS System Heaters Model: 478518673 ID: E32-B001 The MSIV LCS Heaters are located in the Auxiliary Building. They are required to operate for 100 days following a LOCA only. The heater does not function at any other time, normal or accident. The only harsh environ-mental parameter for the equipment location is radiation (2.11 x 106 Rads TID). The EQ documentation for this item shows that a similar unit was operationaly tested for 124 days, however it was not exposed to radiation.

The only radiation susceptible part of the heaters is the Raychem Stilan insulated w to 2.0 x 10gre. This Rads type TID. of wire has Therefore, been qualified it is concluded by MSIV that the Franklin LCSInstitute heaters meet the requirements of NUREG-0588. .-

Item: LPCS and HPCS Motors .

Model: SK6348XC94A (LPCS), 5K6357XC17A (HPCS)

ID: E21-C001 (LPCS), E22-C001 (HPCS)

The LPCS and HPCS motors are located in the auxiliary building at an-elevation of 109'. The motors must be able to withstand and operate during exposure to the harsh environment created by a high energy line break and the environment occurring for 100 days following the accident. The harsh 22

l environmental pararr.eters specified are: temperature (150 F), Humidity (90%), and Radiation (2.29 x 106 Rads TID). Operability time is 100 days.

The EQ documentation for these items indicated that a similar motor was exposed to environmental conditions which exceeded those listed above by adequate margin. Documentation showing similarity of the installed

. motors to the test motor was adequate. The 100 day operating time was established by test and analysis, (216 hours0.0025 days <br />0.06 hours <br />3.571429e-4 weeks <br />8.2188e-5 months <br /> 0 383*F which is equivalent to 3000 hours0.0347 days <br />0.833 hours <br />0.00496 weeks <br />0.00114 months <br /> 0 311' [ winding temperatures]). It is concluded that these pumps meet the requirements of NUREG-0588.

Item: Kerite 9.0 kV Power Cable Model: I/C, 750 MCM and Triplex, 4/0 AWG Ir: QSR21T000C This cable is used outside containment throughout the plant to trans-umps. The harsh environmental parameters mit powerare:

specified to safety related p(340 F), Pressure (101 psig max.), Humidity Temperature (100%), and Radiation 4.21 x 107 Rad TID. The required operating time is 100 days.

The review of the EQ documentation for this cable indicated that samples of the cable were subjected to harsh environmental conditions which exceeded those listed above by adequate margin. The cables were tested for 100 days only without the 10% operating time margin. This is not con-sidered significant, however, because the cables were pre-aged before LOCA testing. It is concluded that the cable meets the requirements of NUREG-0588.

Item: ITT Electric Control Actuator Model: NH91A ID: IT48-PD2-F5008 The Electric Control Actuator is used to control the HVAC dampers in the Standby Gas Treatment Systery. The actuator is located in an environ-ment, where radiation (5.7 x 103 Rads TID) is the only harsh parameter.

Review of the EQ documen exposed to a TID of 3.96 x 10pation Rads indicated thatoccurred and a failure a similardue unittohad out-been gassing of the oil in the unit. The failure, however, occurred at a radia-tion value which exceeded the specified value, listed above, by adequate margin. Two other test failures related to relief valves were adequately addressed in the documentation. It is concluded that the actuator meets the requirements of NUREG-0588.
