SUBJECT:

FARLEY UNIT 1: EVALUATION OF THE ELECTRICAL, INSTRUMENTATION AND CONTROL (EI&C) ASPECTS OF THE DELETION OF REACTOR TRIP ON TURBINE TRIP BELOW 50 PERCENT POWER (TAC 11053)

In accordance with your request per TAC 11053, enclosed is the Plant Systems Branch Safety Evaluation Report pertaining to the Farley license amendment request for deletion of reactor trip on turbine trip below 50 percent pcwer.

As indicated in the Safety Evaluation Report, we have concluded that the change is acceptable. However, this review was done prior to the B&O effort. The approval of this change may not be consistent with the B&O ef fort. Namely, that this modification deletes reactor trip on turbine trip below 50% power. We would recomend your holding the enclosed Safety Evaluation Report pending completion of the B&O effort, and that the licensee be so notified.

In any event, we consider this TAC completed.
