SUBJECT:

ELECTRICAL DISTRIBUTION SYSTEM FUNCTIONAL INSPECTION This letter confirms the dates of May 3 - 7, and May 17 - 21, 1993, for a special electrical distribution system functional inspection at the Seabrook Station. A pre-inspection visit by l

the team to the plant site is also scheduled on April 19 - 22,1993, to gather information for this inspection, for a plant tour and badging of the inspectors. Our plans were discussed with your staff during telephone calls with Mr. J. Peschel of your organization.

The inspection will take place at the Seabrook Station, New Hampshire, where an entrance meeting is scheduled for 1:00 p.m. on May 3,1993. The exit meeting is tentatively scheduled for 11:00 a.m. on May 21,1993, at the Seabrook Station.

The primary objective of the inspection will be to determine whether the electrical distribution system (EDS), as designed, installed, and configured at the Seabrook Station is capable of performing its intended functions during all plant operating and accident conditions. In addition, an assessment of the engineering and technical support provided to ensure continued operability of the EDS will be performed.

To support the comprehensive scope of this inspection, we request that your staff be prepared to provide, on April 19, 1993, a presentation which addresses, as a minimum, the following i

areas:

1.

Seabrook's organization, clearly identifying responsibility, accountability, and flow of authority.

2.

Station ac and de distribution systems arrangements.

3.

Lineup of breakers during startup, normal, and emergency operation of the plant.
