SUPPLEMENTAL RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION EMERGENCY DIESEL GENERATOR TESTING SALEM GENERATING STATION UNIT NOS. 1 AND 2 FACILITY OPERATING LICENSE NOS. DPR-70 AND DPR-75 DOCKET NOS. 50-272 AND 50-311 BY letter dated March 3, 1991, PSE&G proposed changes to the Salem Emergency Diesel Generator (EDG) Technical Specifications.

Based on their review of the proposed changes, NRC staff provided questions to PSE&G in a letter dated October 18, 1991. By letter dated December 19, 1991, PSE&G responded to those questions, with the exception of Question 1, which involved the recent revision of the Salem EDG load calculation. The following is PSE&G's response to Question 1 of the October 18, 1991 letter.

Question 1 The current FSAR states that the maximum load would not exceed the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating of 2750 KW for the diesel generator.

However, the current load study referenced in your submittal, identified as Salem Generating Station Diesel Generator Load study, Report No. AEI-PSEG-8811-DR-OOl, indicates credible accident scenarios or "operational cases" where the diesel generator load profile exceeds the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating of 2750 KW.

Provide a copy of the 50.59 Safety Evaluation that has been performed showing the diesel generator loading capacity is adequate under the new load profiles.

Response

Revision o of the study showed a peak load of 2872 KW for 16 minutes, which is below the one half hour rating of 3100 KW. The load dropped below the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating at the 16 minute operating point. Revision O of the load study concluded that diesel loading was acceptable because the manufacturer's

- Document Control Desk NLR-N92014 JAN 3 1 1992 specified ratings (i.e., load and duration) were not exceeded.

The original load study results were discussed in our March 3, 1991 letter, in order to support our proposal to establish surveillance test criteria consistent with the maximum calculated EDG loading conditions.

During an internal review of the load study in September 1990, PSE&G identified discrepancies in the horsepower values used for several pumps. A Discrepancy Evaluation Form (DEF) was generated in accordance with our Engineering Discrepancy Control process, requiring an operability assessment. The assessment concluded that operability was not in question because the specified EOG ratings would not be exceeded. This conclusion remains valid to date.

Longer term resolution of the DEF included revision of the load calculation based on corrected horsepower values and review of input assumptions against the emergency operating procedures. A change to the UFSAR was not initiated until after the revised calculation and 10CFR50.59 evaluation were completed.

During a safety system functional inspection (SSFI) of the RHR system in April 1991, the NRC inspection team noted the EOG load study had not undergone the necessary design verification (Inspection Report 50-272/91-80, 50-311/91-80). The inspection team concluded there was no immediate concern regarding the operational readiness of the EDG's, and issued a Notice of Violation for the lack of design verification.

The load study referenced in our submittal of March 3, 1991 has been revised, and is superseded by Salem Diesel Generator Load Calculation ES-9.002-0. The revised calculation has been used as the basis for the attached 10CFR50.59 evaluation, which addresses worst case diesel loading scenarios resulting in loads greater than 2750 KW.

The worst case (i.e., peak load) scenario has been identified as a Loss of Coolant Accident (LOCA), coincident with Loss of Offsite Power (LOOP) and failure of the Auxiliary Feedwater system (AFW) runout protection. This loading condition assumes the ECCS and motor driven AFW pumps operate in runout condition.

The resulting worst case load is 2853 KW for a maximum of 30 minutes. This load is within the two hour rating of 2860 KW.

Several other LOCA/LOOP cases result in loads approaching the two hour rating. In all cases, the EOG loads stabilize, with long term (> 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />) demand falling below the continuous rated load of 2600 KW. The load profiles for the various scenarios are attached to the 50.59 evaluation.

J.2 May the Proposal:

a. Create the possibility of an accident of a different

~ than any previously evaluated in the SAR?

YES - - - NO

b. Create the possibility of a malfunction of a

'different type than any previously evaluated in the SAR?

YES NO Discuss the bases for the determinations and identi:y the pertinent SAR sections that were reviewed to ~ake the determinations (use continuation sheets if required):

a. Al though not directly addressed in the SAR, the - i calculation considered a loss of oftsite power  !

coincident with a large pipe break and failure of an auxiliary feedwater pump controller. This scenario puts the motor driven A~W pump and all ECCS pumps in a runout condition to determine maximum diesel generator loading.

This was confirmed through iteration to result in maximum loading. The results verify that the diesel generators will operate within the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating thereby assuring that the diesel generators are capable of supplying loads during the worst case scenario. The conservative assumption used to identify the* limiting EOG load demands do not create the possibility of a new accident but, demonstrate that the worst case scenario does not result in unacceptable EDG demands. Sections 8.3 and 15 were reviewed in making this determination.

b. The diesel generators and all associated equipment is unaffected by this design change, other than the increase of the maximum kilowatt load on the diesel generator. The increased load is within the EDGs' allowable operating design parameters. Therefore, this change will not cause a malfunction not previously evaluated in the SAR. Sections 8.3 and 15 were reviewed in making this determination.

J.J 9oes the p~oposal reduce the margin of safety as defined in the basis for any Technical Specification?

YES NO Discuss the bases of the determination and identify the pertinent Technical Specification sections that were reviewed to make the determination (use continuation.

sheets if required):

The Diesel Generator Loading Calculation verifies that the ~axirnurn loading demand would remain w{thin the manufacturers ratings, which establish the margin of safety for EDG capability. Testina perfor:ned per Unit 2 Technical Spe**:.fication, 4.8.1.1.2.c.7, (24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> endurance test) presently den- _ns tra tes the ability of the diesels to operate at > 2860 kW for two hours. Although not required by Technical Specifications, Unit 1 testing performed in June, 1991, demonstrated the diesels ability to operate at their approximate maximum calculated load demand for one hour. The following chart compares Unit 1 test figures to the calcul~tion's (ES-9.002) worst case one hour load transient.

EDG lA EDG lB EDG lC June '91 2850 kW 2800 kW 2600 kW ES-9.002 2824 kW 2798 kW 2673 kW As is apparent the le EDG calculated load is greater than the test figure, however, *due to the uniformity of all six diesels for both uni ts and the testing of EDG' s lA and lB to values greater t:han the calculated lC load of 2673 kW the unit (lC) is deemed acceptable. The ability of the EDG's to support their design load requirements will be demonstrated by periodic testing. Therefore, there is no reduction in the margin of safety associated with this change.

If ALL answers in Section J are "NQ", the proposal does NOT involve a USQ.

If ANY answer in Section 3 is "ll.§", the proposal involves a USQ.

10C7llS0.59 RBVJP AJ1D SAJT!'T mLUATIO* CCOll'l'IlluBDl 4.0 TECHNICAL SPECIFICATION REVISION DETERMINATION -Does the proposal involve a Technical Specification change?

YES NO Identify the pertinent Technical Specification sections that were reviewed to make the determination:

Section 4.8.1.1.2, Surveillance Requirements, was reviewed and found to require revisions to address the following issues:

For both units the Load Rejection Surveillance must be changed to address the loss of the largest load, the Service Water Pump, at 1030 HP, 809 kW. Unit 1 Technical Specifications presently require a surveillance test to verify load rejection without tripping using a load of 785 +/- 40 kW to simulate the loss of the largest load, a 1000 HP Service Water Pump. The Unit 2 Technical Specifications stipulate a load ~ 785 kW. The Service Water Pumps are now rated at 1030 HP and the load rejection test must be increased to > 809 kW.

However, load rejection tests accounting for .the revised service water pump motor rating may be performed with the Technic~l Specifications as written. For Unit l, the high end of the tolerance is 825 kW, which exceeds the 809 kW rating of the pump motor. Unit 2 Technical Specifications do not specify a maximum load for the test (ie. > 785 kW).

CONTINUATION SHEET 2.0 10CFR50.59 REVIEW (Continued from page 2)

a. Section 8.3, Onsite Power, and associated tables will change to incorporate the results of the diesel genera tor load study. Results of the study indicate that for a Blackout all diesels operate below their continuous rating, 2600 kW. For some Blackout coincident with LOCA scenarios there will be a maximum load of 2853 kW for a maximum of 30 minutes, which is within the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating of 2860 kW. Finally, the study concludes that all diesel loadings will stabilize and the Diesel Generators will be operated below their continuous rating for all accident conditions.

b. Al though this eval ua ti on does not directly involve any procedure changes, it may be used to support EDG test procedure revisions consistent with the results of the Load Calculation.

c. Section 8. 3 .1. 5, Standby Power Supplies, was reviewed and the results of the diesel generator load calculation proposes no tests or experiments not described in the SAR. Tests required to demonstrate acceptable EDG operation are not precluded by the Technical Specifications as written.

3.1 USQ DETERMINATION {Continued from page 3) 3.1 a. This evaluation addresses increased Emergency Diesel Genera tor loading as presented by the Diesel Genera tor Loading Calculation (ES-9. 002). Increased loading has -

no impact on the initiation of any previously evaluated accident. Therefore, there is no increase in the probability of an accident previously evaluated in the SAR.

<'- . 10Cl'R50. 51 CONTIHUATION SHEET 3.1 USQ DETERMINATION (Continued from page 7) 3.1 b. The Diesel Load Calculation (ES-9~002) has determined that the diesels will operate safely within their 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> operating range. The results of the calculation determine the maximum loading to be 2853 kW for a maximum of 30 minutes. Although the 2853 kW loading is greater than the 2750 kW of the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating it is within the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating of 2860 kW. Presently the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating is not in the SAR, but has been part of the baseline documentation since the plants inception and has been verified through OEM (ALCO) documentation, copy attached. The 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating is being added as part of this change. The diesel generator ratings for Units 1 &

2 are:

1/2 hour 3100 kW 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> 2860 kW 2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> 2750 kW continuous 2600 kW Accordingly there is not an increase in the consequences of an accident previously evaluated in the SAR.

Sections 8.3, onsite Power Supply, and 7.1 Instrumentation and Control of the SAR were reviewed in making this determination.

3.1 c. As a result of this Diesel Loading Calculation the maximum load has increased to 2853 kW. Since this maximum load is within the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating of the diesel generator there is no increase in the probability of an occurrence of a malfunction of equipment important to safety. Sections 8.3, Onsite Power Supply, and 7.1 Instrumentation and Control of the SAR were reviewed in making this determination.

3.1 d. The Diesel Loading Calculation analyzed the effects of equipment failures following a OBA/LOOP and found that in all cases the remaining two diesel generators would successfully supply power to the vital buses. The Diesel Generator Loading Calculation identified an increase in the single largest emergency load, service water pump, from 785 kW to 809 kW. Inadvertent rejection of the pump is a less limiting failure than the loss of a diesel. Therefore, there is not an increase in the consequences of a malfunction of equipment important to safety.
