à AEP:NRC:0894Q Donald C. Cook Nuclear Plant Unit 1 Docket No. 50-315 License No. DPR-58 TECHNICAL SPECIFICATION CHANGE REQUEST CALCULATION TO SUPPORT LTOP SETPOINT U. S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, D. C. 20555 Attn:,,T...E. Murley June 18, 1991

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).
