Subject:

Catawba Nuclear Station, Units 1 and 2 Docket Nos. 50-413 and 50-414 Proposed Changes to Technical Specifications 3/4.3.1 and 3/4.3.2 Increased Surveillance Test Intervals and Allowed Outage Times for Reactor Trip System (RTS) and Engineered Safety Features Actuation System (ESF/.S)

1. Letter from M.S. Tuckman to NRC, dated January 25, 1993

2. Letter from Charles E. Rossi to Roger A. Newton, dated February 22,1989 Gentlemen:

During a recent conversation between R.E. Martin (NRC) and L.J. Rudy (DPCo), it was noted that in Reference 1, the proposed Action 14a of Table 3.3-3 (Engineered Safety Features Actuation System Instrumentation, Containment Sump Recirculation Functional Unit 9a, Automatic Actuation Logic and Actuation Relays) contained an eight-hour requirement to be in hot standby when the conditions of the action statement are not met. In Reference 2, a twelve-hour requirement to be in hot standby had been previously approved by the NRC for this functional unit. Therefore, the proposed Action 14a is actually more conservative than what was previously approved by the NRC. Also, the proposed Action 14a contains a two-hour allowance for bypass of a channel for surveillance testing whereas Reference 2 previously approved a four-hour allowance.

By this letter, Catawba is modifying the technical specification amendment request submitted in Reference I to request the full amount of relief previously approved by the NRC for this functional unit. The marked-up technical specification pages which reflect this request are attached. (Note that Functional Unit 9a will now refer to Action 14 of the Reference I submittal; Action 14a of Reference I will be deleted; and Action 14b of Reference I will be renumbered as the new Action 14a.) The conclusions of the original safety analysis and No i

Significant Hazards Consideration Analysis continue to remain valid as a result of tids additional 750 5 (6 O I5 9 5 ff,
