Amendment Number 167 Implementation Additional Condition Date WCNOC will revise the WCGS containment isolation fault tree model prior to utilization of the requested cointainment-isolation valve Completion Time extensions by either: 1) modeling containment isolation valves for at least one of each WCAP-1 5791 penetration type applicable to WCGS, including penetrations to the containment atmosphere greater than 2 inches in diameter or 2) modeling all containment isolation valves associated with this license amendment request, including penetrations to the containment atmosphere greater than 2 inches in diameter. A peer revi 'ew of the changes to the containment isolation fault tree model, including addressing Category A and Category B findings, will be completed following revision to the containment isolation fault tree model.

Prior to implementation of the amendment WCNOC Will implement in its procedures the requirement to confirm that the remaining containment isolation valve(s) in the affected penetration(s) are in their correct position(s) prior to performing maintenance on a containment isolation valve.'

Prior to the start of Refueling Outage 16 Prior to the start of Refueling Outage 16 167 Amendment No. 167 Amendment.

Number Implementation Additional Condition Date 123 163 163 For SRs that existed prior to this amendment whose intervals of performance are being extended, the first extended surveillance interval begins upon completion of the last surveillance performed prior to implementation of this amendment..

The licensee will perform a one-time load acceptance test of the Sharpe Station prior to the first use of the 7-day Completion Time of Required.

Action B.4.2.2 of TS 3.8.1. The test shall utilize a nearby large -motor for the purposes of simulating a large plant load. This test will be performed in conjunction with a dynamic voltage flow analysis.

The licensee will coordinate with KEPCo to ensure the load capability testing/verification is performed within 8 months prior to utilization of the 7-day Completion Time of Required Action B.4.2.2 in TS 3.8.1. The load capability testing/verification will consist of either crediting a running of the gensets for load for commercial reasons for greater than 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months or tested by loading of the gensets for greater than 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months to a load equal to or greater than required to supply safety related loads in the event of a station blackout.

The licensee will ensure the RCP. seal model from WCAP-1 5603, Rev. 1 -A, "WOG 2000 Reactor Coolant Pump Seal Leakage Model for Westinghouse PWRs" is utilized in the -2002 WOGS PSA Model. The licensee will verify that the utilization of the Sharpe Station for supporting an extended DG Completion Time in the 2002 WCGS PSA Model meets the risk acceptance guidelines of Regulatory Guide 1.174 and Regulatory Guide 1.177. Additionally, the licensee will include the risk impact of the Sharpe Station in the Safety Monitor, i 'ncluding adding an activity to the Activity Table that will account for the impact of the plant configuration associated with crediting the Sharpe Station during the use of an extended Completion Time for pre-planned maintenance activities.

This amendment shall be implemented by December 31,i 1999.

Prior to the first use of the 7-day Completion Time of Required Action B.4.2.2 of TS 3.8.1.

Prior to the use of the 7-day Completion Time of Required Action B.4.2.2 of TS 3.8.1.
