Dear Mr. Sylvia:
SUBJECT'LECTRICAL DISTRIBUTIONSYSTEM FUNCTIONALINSPECTION (EDSFI) FOR NINE MILEPOINT UNIT2 This letter confirms the dates of November 29 - December 3, 1993, and December 13-17, 1993, for a partial EDSFI at Nine Mile Point Unit 2. A partial EDSFI is being conducted because a self-assessment EDSFI was conducted by Niagara Mohawk from, March 16, 1992 to May 1, 1992.
Our plans for the inspection were discussed with your staff during a telephone call between Messrs. A. Pinter and A. Raju of your organization and Mr. Leonard Cheung of the NRC Region I office. The inspection willtake place at the engineering office in Salina Meadow and at the plant site.
A management entrance meeting is scheduled for 1:30 p.m., on November 29, 1993, at the engineering office in Salina Meadow, New York. The management exit meeting is tentatively scheduled for 10:30 a,m., on December 17, 1993, also at the Salina Meadow office.
The purpose of this inspection is to assess the adequacy of your EDSFI and to determine whether the electrical distribution system at Nine Mile Point Unit 2 is capable of performing its intended functions as designed, installed, and configured during all plant operating and accident conditions.
To support the scope of the inspection, we request that you provide us at least two copies of the documents identified in the enclosure by November 12, 1993, to be picked up by Mr. Leonard Cheung at the Salina Meadow office. We also request that Niagara Mohawk be prepared to provide, on November 29, 1993, following the entrance meeting, a brief presentation to the inspection team, which addresses the design of the station electrical distribution system and associated support systems, and your self-assessment EDSFI.
