Dear Mr. Mroczka:
I
SUBJECT:
MILLSTONE NUCLEAR POWER STATION UNIT 3'- RESPONSE TO STATIO!'
BLACK 0UT EVALUATION (TAC NO 68568)
By_ letter dated August 20, 1990,.the NRC staff forwarded'its evaluation of' your response to the station blackout (SBO) rule (10 CFR 50.63) for Millstone Unit 3.
Your letter of September 26, 1990, responding to our letter of August 20 1990, informed the NRC staff;that,
" Presently, the hardware modification is the insta11ation of an independent air-cooled diesel generator as the.n1 ternate AC (AAC) source for Millstone Unit No. 3.
The scheduled completion of this modification and associated procedures is the end of the11992 refueling outage, currently planned to commence October 1992. NNECO..
realizes that completion of the equf;nent and procedure modifications exceeds the two-year window as defined in 10 CFR 50;63(c)(4)."
The schedular requirement of 10 CFR-50.63 allows:the schedule for required' modifications to be "... established by the NRC staff in consultation and coordination with the affected licensee." ~ Accordingly, we have' reviewed your proposed schedule, contained in your. letter dated September 26; 1990 concerning installation of the ACC (and completion of associated procedures and' testing) for Millstone Unit 3 which provide's for an extension of a proximately two months beyond the two year requirement of 10 CFR.50.63(c)p(4).
We conclude that installation of the ACC prior to startup.following the 1992 refueling outage is acceptable. Should your schedule'for installation of the ACC change, please promptly notify us.
Sincerely, Original signed by._
