Document Control Desk Washington, D.C. 20555 Gentlemen:
Subject:
Docket No. 50-206 Amendment Application No. 188, Supplement 3 San Onofre Nuclear Generating Station, Unit 1
Reference:
Amendment Application No. 188, Supplement 2, dated September 9, 1991 Enclosed is Supplement 3 to Amendment Application 188, which is a revision to our previous submittal for Emergency Core Cooling System (ECCS) Technical Specifications (see reference).
We have reduced the scope of our previous request to limit the changes to those which are needed to provide relief from unnecessary plant shutdowns under Specification 3.0.3, and to satisfy prior commitments made in Licensee Event Reports for the Containment Spray and Recirculation Systems (see enclosure).
The enclosed change affects Section 3.3.1, "Safety Injection and Containment Spray Systems -
Operating Status."
The existing specifications were written prior to the Standard Technical Specifications (STS), and therefore do not contain standard 72-hour action statement time limits. As a result, we have needed a Waiver of Compliance from Technical Specification 3.0.3 to perform routine maintenance or surveillances for Emergency Core Cooling System (ECCS) components. The proposed changes to the specifications will eliminate the need for additional waivers and the potential for unnecessary plant shutdowns.
We had previously requested extensive changes to Section 3.3 (ECCS) and several other specifications.
Since we plan to shutdown Unit 1 at the end of the current fuel cycle, we are limiting our requested changes to a minimum to reduce the amount 9206120232 920605 PDR ADOCK 05000206
