Mr. B. D. Kenyon President - Nuclear Group Northeast Utilities Service Company c/o Mr. Terry L. Harpster Director - Nuclear Licensing Services P.O. Box 128 Waterford, CT 06385
SUBJECT:
MILLSTONE UNIT 3 - REQUEST FOR ADDITIONAL INFORMATION RELATED TO 3 ALTERNATE AC POWER SOURCE REQUIREMENTS (TAC NO. M96054)
)
j
Dear Mr. Kenyon:
1 During a review of the Millstone Unit 3 station blackout (SB0) systems, the special inspection team (SIT) identified a concern with the design of the 4 alternative ac (AAC) power source, the SB0 diesel generator (SBO-DG), and its dedicated battery. The AAC power source may not be available if SB0 occurs due to a loss of onsite power (emergency diesel generators) after one hour of loss of offsite power (LOOP). The AAC power source at Millstone Unit 3, is 4
controlled and monitored by a computer. The AAC power system design includes two batteries (one 48-volt for the computer and the other 125-volt for DG field flashing, oil pump, and breaker control power). The battery chargers for these batteries are fed from offsite power when the AAC power is not ,
operating. If the LOOP occurs first, these batteries will be depleted due to '
connected loads (computer for 48-volt battery and oil pump for 125-volt ;
battery). Northeast Nuclear Energy Company (NNECO) determined that if the loss of onsite power occurs after one hour of the LOOP event, the batteries will be drained sufficiently so that the SB0-DG cannot be started,
~
l By letter dated March 30, 1990, NNEC0 stated that the AAC power source will meet the criteria specified in Appendix B to NUMARC 87-00. By letter dated '
! August 27, 1996, the NRC staff requested additional information on how Millstone Unit 3 meets the NUMARC 87-00, Appendix B criteria; specifically items B.8(e) and B.8(f). By letter dated October 18, 1996, NNECO agreed that the SB0-DG design and/or operation should be modified to ensure availability of the SB0-DG at any time during the postulated 8-hour LOOP, regardless of the j relative timing of emergency diesel generator failure / unavailability. NNEC0 stated that several options were under consideration to achieve this. NNECO committed to identify to the NRC staff by December 31, 1996, the specific design / operation modification required to be made to ensure the availability j of the SBO-DG at any time during a postulated 8-hour LOOP.
In a letter dated December 20, 1996, NNEC0 stated that it has completed its review of the options available to ensure the availability of the SB0-DG and 4
has determined that the best solution is to modify the design of the SB0
- system. The modification may require operator actions within the first hour NRC HLE CMSCSM D0065 9701210073 970113 PDR ADOCK 05000423 P PDR r

ALTERNATE AC POWER SOURCE REQUIREMENTS i
MILLSTONE UNIT 3 By letter dated December 20, 1996, Northeast Nuclear Energy Company (NNECO) i stated that it has completed its review of the options available to ensure the availability of the station blackout diesel generator (S30-DG) and has i determined that the best solution is to modify the design of the SB0 system.
! The modification may require operator actions within the first hour after a 1
loss of offsite power (LOOP) to power the SBO-DG auxiliaries from either the 1
- SBO-DG or from another diesel generator. The staff has several concerns about j the proposed modification and NNECO's responses to the following requests are ,
j needed:
! l j 1. After a LOOP, how soon will the SB0-DG auxiliaries be powered from the I
! SBO-DG or ant,ther diesel generator? Also, which procedure will cover i j this requirememi.i
) 2. If the SBO-DG is used to power the auxiliaries:
j a. How long will the SB0-DG be running and at what load?
l j b. What are the consequences of running the SB0-DG at light load 4 conditions? !
j c. What is the impact on the SBO-DG fuel supply in view of the fact
- that the SBO-DG may be running for an additional 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />?
$ 3. If another diesel generator is used to power the auxiliaries:
- a. Provide details of this diesel generator (capacity, connectability, availability, reliability, etc.)
- b. Is this a new diesel generator?
- c. Provide details on how it will be interfaced with existing switchgear and equipment.
- 4. Provide details regarding the testing and operator training requirements resulting from this modification.
