Dear Mr. Stall:

By letter dated January 16, 2002, Florida Power and Light Company requested an amendment to Technical Specification (TS) Surveillance Requirement 4.8.1.1.2.g.7 regarding the 24-hour functional test of the emergency diesel generators. The U.S. Nuclear Regulatory Commission staff has reviewed your submittal and finds that a response to the enclosed request for additional information is needed before we can complete the review.

This request was discussed with your staff on January 28 and 31, 2002, and it was agreed that a response would be provided within 30 days of receipt of this letter.

If you have any questions, please contact me at (301) 415-1496.

Sincerely,

1. Please describe the various events that can cause loss-of-offsite power (LOOP) while the emergency diesel generator (EDG) is being tested and paralleled to offsite power.

In addition, please provide a sequence of events, including timing, assuming that the EDG protective features actuate in response to a LOOP.

2. Please discuss how many EDGs are needed to perform a safe shutdown during a design basis accident. In addition, please discuss the actions taken when one EDG is declared inoperable for testing to ensure that testing does not affect the independent safe shutdown capabilities of the remaining EDGs or the other safety systems.
