DOCKET NO. 50/395 OPERATING LICENSE NO NPF-12 TECHNICAL SPECIFICATION CHANGE - TSP 930002 LIMITING SAFETY SYSTEM SETTINGS - REACTOR TRIP SYSTEM INSTRUMENTATION TRIP SETP0INTS ENGINEERED SAFETY FEATURES ACTUATION SYSTEM INSTRUMENTATION SETPOINT

]

In accordance with 10 CFR 50.90, South Carolina Electric & Gas Company (SCE&G) is submitting an amendment request to License NPF-12 to change the Technical Specifications (TS) for VCSNS. The proposed change revises TS Tables 2.2-1, Reactor Trip System (RTS) Instrumentation Trip Setpoints, and 3.3-4, Engineered Safety Feature Actuation System (ESFAS) Instrumentation Setpoints,'and associated Bases.

SCE&G requests NRC review and approval of this change by August 31, 1994, in order to support Refueling Outage 8 activities.

The purpose of this change is to include additional Process Measurement Accuracy (PMA) uncertainties for the narrow range steam generator water level low-low trip functions for the Model D3 steam generators and to change Tables 2.2-1 and 3.3-4 to a two column format.

The amendment request is contained in the following enclosures:

Enclosure 1 - Proposed TS Change Enclosure 2 - Description and Safety Evaluation Enclosure 3 - Determination of No Significant Hazards Consideration The proposed TS change has been reviewed and approved by the Plant Safety Review Committee and the Nuclear Safety Review Committee.
