Dear Dr.Murley:

This letter and its attachment have been prepared in response to a request by Mr.T.G.Colburn of your staff for a copy of the calculation that supports the proposed revision to the Donald C.Cook Nuclear Plant Unit 1 low temperature overpressurization protection (LTOP)setpoint submitted in our letter AEP:NRC:08940 dated October 29, 1990.A copy of this calculation is attached to this letter.Attachment 2 to this letter contains a copy of three of the four documents referenced in the above-noted calculation.

Specifically, Attachment 2 contains the following:

1)An AEPSC internal memorandum that states that the methodology used to calculate the Unit 2 LTOP setpoint is also applicable to Unit 1, 2)A Westinghouse report entitled,"D.C.Cook Unit 2 Low Temperature Overpressure Protection System (LTOPS)Setpoint Evaluation," dated June 1989, and 3)The applicable portion of the Westinghouse instruction and operating book entitled,"Controlled Leakage Seal Reactor Coolant Pump Model W-11001-Bl (PP-045)." The fourth document referenced by the subject calculation is WCAP-12483 dated January 1990.This document is not included as part of this letter as it has been previously provided (reference our letter AEP:NRC:0894M dated June 22, 1990)..t 9 1 06270 i 24 91M<8-PDR ADOCK 050003i5 I'DR
