Dear Hr. Sylvia:
SUBJECT:
STATION BLACKOUT RULE SUPPLEMENTAL SAFETY EVALUATION RESPONSE CLOSURE NINE MILE POINT NUCLEAR STATION, UNIT 2 (TAC NO. M68571)
On July 21,
- 1988, the Code of Federal Regulations at 10 CFR Part 50, was amended to include a new Section 50.63, entitled, "Loss of All Alternating Current Power," (Station Blackout).
The station blackout (SBO) rule requires that each light-water-cooled nuclear power plant be able to withstand and recover from an SBO of specified duration.
The SBO rule also requires that information defined in the rule be provided to the staff for review.
By letters dated April 13,
- 1989, and April 3,
The NRC staff's Safety Evaluation (SE) pertaining to NMPC's initial responses was transmitted to you by letter dated May 29, 1991.
The NRC staff found the proposed method of coping with an SBO to be acceptable, subject to the satisfactory resolution of several recommendations which were itemized in the staff's SE.
NHPC responded to the staff's SE, and specifically to the recommendations, by letter dated July 1, 1991.
The NRC staff reviewed NHPC's response and found it to be acceptable as documented in a Supplemental Safety Evaluation (SSE) dated November 21, 1991.
However, this acceptance was based on the resolution of several additional recommendations which were itemized in the SSE.
By letter dated January 2,
- 1992, NHPC addressed the additional recommendations which were itemized in the SSE issued by the NRC staff:
The NRC staff reviewed the confirmations and commitments concerning the recommendations and finds them to be acceptable.
This completes our review under TAC No. H68571.
Please notify the NRC in writing when NMPC has completed all analyses, evaluations, and procedural changes committed to by NHPC.
