c. Pump and Motor-Operated once/ month ,

Valve Operability except Recirculation Pump discharge valves.

2. From and after the date that one of the Core Spray 2. When it is determined that one Core Spray Subsystems is made or found to W inoperable for Subsystem is inoperable, the operable Core Spray any reason, reactor operation is permissible only Subsystem, both LPCI Subsystems (except the during the succeeding seven days unless such Recirculation System discharge valves) and the subsystem is sooner made operable, provided.that diesel generators required for operation.of such during such seven days, all active components of components if no external source of power were the other Core Spray Subsystem, the LPCI available, shall be demonstrated to be operable 1 Subsystems, and the diesel generators required for immediately. The operable Core. Spray Subsystem l operation of such components if no external source shall be demonstrated to be operable daily of power were available, shall be operable. thereafter.

3. From and after the date that one of the LPCI pumps 3. When it is determined that one of the LPCI pumps l 1s made or found to be inoperable for any reason, is inoperable, the remaining active componente of j reactor operation is permissible only during the the LPCI (except the Recirculation System  !

During the inspection / repair of the impeller wear For the purpose of performing inspection / repair of rings on each LPCI pump during the 1986-1987 the irspeller wear rings on each LPCI pump during operating cycle, the remaining active components the 1986-1987 operating cycle, reactor operation of the LPCI Subsystem (except Recirculation System.

is permissible only during the succeeding 14 days discharge valves), the Containment Cooling from the time each pump is made inoperable unless Subsystems, both Core Spray Subsystems, and the such pump is sooner made operable. Additionally,. diesel generators required for operation of such during the out-of-service time, the remaining components if no external source of power were active components of the LPCI Containment Cooling available, shall continue to be demonstrated Subsystem and all active components of both Core operable on a monthly basis as specified in Spray Subsystems and the diesel generators Technical Specifications 4.5.A.1 and 4.10.A.1.
