Subject:

Docket Nos. 50-361 and 50-362 Amendment Application Nos. 151 and 135 Supplement 1 Extension of Completion Time for Low Pressure Safety Injection Train San Onofre Nuclear Generating Station Units 2 and 3

Reference:

CE0G CE NPSD-995, " Joint Applications Report for low Pressure Safety Injection System A0T Extension," May 1995 Enclosed are Amendment Application Nos.151 and 135, Supplement I to Facility Operating Licenses NPF-10 and NPF-15 for the San Onofre Nuclear Generating Station Units 2 and 3, respectively. These amerdment applications consist of Proposed Change Number (PCN)-452, Supplement 1.

PCN-452 proposes to modify Technical Specification (TS) 3.5.2 to extend the allowed outage time from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 7 days for. a single Low Pressure Safety Injection (LPSI) train. This license amendment is a collaborative effort by participating Combustion Engineering Owners Group (CE0G) members based on an integrated review and assessment of plant operations, deterministic and design basis considerations, and plant risk. The above reference, which was submitted to the NRC staff for review and approval under separate cover, supports this change.

Supplement I adds a new TS 5.5.2.14, " Configuration Risk Management Program."

The purpose of the Configuration Risk Management Program (CRMP) is to ensure that a proceduralized Probabilistic Risk Assessment-informed process is in place that assesses the overall impact of plant maintenance on plant risk.

Implementation of the CRMP will enable appropriate actions to be taken or decisions to be made to minimize and control risk when 3erforming on-line maintenance for Systems, Structures, and Components wit 1 a risk-informed Completion Time. . TS 5.5.2.14 will be applicable to TS 3.5.2 because the -1 I

Completion Time for TS 3.5.2 is a " risk-informed Completion Time." i 1
