AEP:NRC:1169B Donald C. Cook Nuclear Plant Units 1 and 2 Docket Nos. 50-315 and 50-316 License Nos. DPR-58 and DPR-74 UPDATE FOR TECHNICAL SPECIFICATIONS CHANGE TO INCREASE THE ALLOWABLE TOLERANCES FOR MAIN STEAM SAFETY VALVES (TAC NOS. M84979 and M84980)

U. S. Nuclear Regulatory Commission Document Control Desk Washington, D. C. 20555 Attn: W. T. Russell March 29, 1994

Dear Mr. Russell:

This letter is submitted in response to Ms. Beth A. Wetzel's November 3, 1993 letter, requesting a revision to our previously proposed amendment request for technical specification to increase the allowable tolerances for main steam safety valves.

Our amendment request (AEP:NRC:1169) provides justification that a safety valve is operable with a lift setting of +3%, and further indicates our intention to reset any value tested to the nominal value of +1% to provide assurance that any setpoint drift will not continue substantially outside the +3% analyzed range.

In addition to stating this requirement in the bases of the respective specifications, a statement has been placed in the surveillance requirements of Specification 4.7.1.1 of both Unit 1 and Unit 2, as requested.

One administrative change has been made in the proposed Technical Specifications 3.7.1.1 and 4.7.1.1 to make them consistent between Units 1 and 2. Specifically, the reference to Table 3.7-4, in the Unit 2 specification, was moved to the Surveillance Requirements of Specification 4.7.1 1 after renumbering Table

~

3.7-4 to Table 4.7-1. Renumbering the table provides consistency between Units 1 and 2. Also on this table, the valve designations have been updated to make them consistent with plant component numbers. A typographical error was corrected in the second sentence of Unit 1 Specification 3.7.1.1.a, which replaced the word "many" with "may."

Mr. W. T. Russell 2 AEP'NRC'1169B to this letter contains marked up copies of the existing specifications. Attachment 2 contains the proposed revised specification pages. It should be noted that these attachments also contain copies of the revised and marked up Specification 3.5.2 and Bases, which were discussed in the original submittal.

The amendments discussed above do not change the results of our analyses concerning significant hazards considerations discussed in the original submittal. Since the changes from our original submittal are administrative in nature, it is our belief that publication of the changes in the Federal Register is not required. Therefore, we believe that the proposed changes will not result in (1) a significant change in the types of effluents or a significant increase in the amount of any effluent that may be released offsite, or (2) a significant increase in individual or cumulative occupational radiation exposure.

This letter is submitted pursuant to 10 CFR 50.54(f) and, as such an oath statement is attached.

Sincerely, PC Vice President Attachments cc: A. A. Blind G. Charnoff J. B. Martin - Region III NFEM Section Chief NRC Resident Inspector J. R. Padgett
