20555 Attention:
Mr. B. J. Youngblood, Project Director PWR Project Directorate No. 4 Re: Catawba Nuclear Station, Unit 1 Docket No. 50-413 Technical Specification Amendment For ESF Surveillance Extension
Dear Mr. Denton:
As a supplement to my February 12, 1986 and March 11, 1986 letters please find attached clarification to the Technical Specification change request for Specification 4.6.6.2.
This clarification is intended to show that only the Engineered Safety Features actuation portion of Surveillance 4.6.6.2 is to be extended until the first refueling outage.
Also, as a-result of discussions with members of your Staff, the amendment to Specification 4.5.3.1 is not needed.
Since Specifications 4.5.2 is referenced by Specifications 4.5.3.1, the amendment to 4.5.2e. is sufficient to cover the extension necessary to 4.5.3.1.
Very truly yours, y
Hal B. Tucker RWO: sib Attachment Dr. J. Nelson Grace, Regional Administrator xc:
