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. 'Jenton:
On February 12, 1986, Duke Power Company requested that certain Technical Specification surveillances associated with the Engineered Safety Features be extended until the Unit I first refueling outage.
Included in this letter was a request to extend the time to perform Technical Specification Surveillance Requirment 4.6.6.2 concerning the Containment Valve Injection Water (NW) System. Surveillance Requirement 4.6.6.2 calls for three separate surveillance which require that each train of the NW System be demonstrated OPERABLE by varifying proper flow rates, proper tank pressure and correct valve position upon receipt of a Containment Pressure High or High-High test signal.
To allow an extension of time to conduct the flow rate portion of Surveillance 4.6.6.2, an exemption from certain requirements of Appendix J would be necessary. This is to clarify that the February 12, 1986 letter requested an extension to the ESF integrated test portion of the surveillance, which is only the part of the surveillance which verifies correct valve position upon receipt of the containment pressure test signals. This part of Surveillance 4.6.6.2 is not required by Appendix J.
Ar. extension of time for the other parts of the surveillance which verify _
the flow rates and tank pressure is not needed. Therefore, no exemption from any Appendix J requirement is necessary.
For the above reasons, the exemption from Appendix J requirement III.C.2.(b) as requested by my March 3, 1986 letter is not necessary and is hereby rescinded.
Very truly yours, fA. /"c
