Agenda for May 11, 1992, meeting with Public Service Electric and Gas Company on Diesel Generators
- 1.
Discuss the basis for changing the power factor from 0.5 (1988 load study) to 0.4 (ES-9.002 load study) for MOVs.
Load study ES-9.002 noted that Limitorque reported a power factor range of 0.2 to 0.8. Also, there were many small loads that have had their KW requirements revised down without a basis for the revision being clearly stated in load study ES-
.9.002.
- 2.
Discuss how representative, in terms of population and expected load conditions, the assumption that the 230 volt motors will be loaded on the EDG at an average of 80% of their nameplate rating, given the 10% sample that was used in load study ES-9.002.
- 3.
Discuss the basis or assumption supporting the timing of the following loads in ES-9.002:
- a.
Cabinet space and jacket water heaters,
- b.
Reactor nozzle support fan, and
- c. Charging pump.
- 4.
Discuss what analyses or tests were performed to ensure that the EDG load accepting capabilities were not adversely impacted in terms of frequency and voltage regulation requirements as described in Regulatory Guide 1.9, Section C.4, given the revised load value for the service water pump (809 KW now vs 785 KW before).
- 5.
Verify that the performance tests conducted by Alco adequately demonstrated the KVA rating of the diesel generator. The staff has noted through EDSFI activities that Alco has used, for qualification testing of safety grade diesel generators, resistiva loads rather than reactive loads.
In addition, discuss whether those tests which established the diesel generator ratings were conducted under anticipated site conditions (i.e., cold start, step load increases).
- 6.
Identify what loads have been added and/or computational errors made since the initial licensing basis that have contributed to the present load profile which is contrary to the UFSAR statements (Section 8.3.1.5.1) that 11 *** the maximum load to be 2750 KW for a maximum of about 30 minutes duration... The time period below 30 minutes, however, is characterized by a load no greater than 2600 KW".
- 7.
Are loads that are sequenced ON at 30 seconds considered auto-connected loads? What is the auto-connected load total, under worst case design basis conditions?
- 8.
The 50.59 evaluation, denoted IEA-1025, indicates that the current surveillance requirement 4.8.1.1.2.b.5 (Unit I) and 4.8.1.1.2.c.8 (Unit

- how the existing surveillance procedure, as currently implemented, meets the 2750 KW limit and how you will assure that future load growth will not exceed the 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> limit.
- 9.
The staff has noted via Information Notice 91-13 and through EDSFI activities that some licensees have not adequately addressed environmental factors that might impact the actual performance of the EDG.
Discuss what derating factors {i.e., ambient room temperature, combustion air temperature) have been considered concerning operation under accident conditions and when the EDG is tested.
- 10.
On page 5 of the Salem Station 50.59 evaluation, IEA-I025, the worst case one hour transient is 2824 KW, 2798 KW, and 2673 KW for EDG IA, EOG 18 and EOG IC, respectively.
However, the load study, ES-9.002, shows the worst case value {i.e., highest value in the first hour) to be 28I2 KW, 2838 KW, and 2687 KW for EDG lA, EDG 18, and EDG lC, respectively.
Please discuss.
