20555 Attention:

Mr. B. J. Youngblood, Project Director PWR Project Directorate No. 4 Re: Catawba Nuclear Station, Unit 1 Docket No. 50-413

Dear Mr. Denton:

i On February 12, 1986, Duke Power Company (Duke) requested that certain Technical Specification surveillances associated with the Engineered Safety Features be extended until the Unit 1 first refueling outage. The postponement of Surveillance Requirement 4.6.6.2 for the Containment Valve Injection Water System also requires on exemption from the requirements of 10 CFR 50 Appendix J,.Section III.C.2.(b).

In the previous letter, a safety analysis was provided. The conclusion reached was that given the short duration of the extension (at most 5 months) along with the testing that would be done on individual circuits and components, there would be no significant reduction in the margin of safety provided.

Based on the justification provided in the February 12, 1986 letter an exemption from the requirements of Appendix J should be granted in accordance with 10 CFR 50.12(a)(2)(v). Special circumstances exist in that the exemption would provide only temporary relief (5 months) from the requirements of Section III.C.2.(b) of Appendix J in order to avoid a reactor shutdown. Duke has and will make a good faith effort to comply with the regulations.

It is our intent to conduct the surveillances as soon as possible.

If the unit is placed in a condition where the tests can be conducted (i.e., Cold Shutdown for at least 2 weeks), the surveillance will be performed.

Based on the previous submittal, and the above justification, it is our conclusion that the requested exemption is authorized by law, will not

present an undue risk to the public health and safety and is consistent L

with the comn defense and security.
