ELECTRICAL POWER SYSTEMS LIMITING CONDITION FOR OPERATION (Continued)
- For a 30 day period for diesel generator 2A during the Unit 2 first refueling outage, with Unit 2 in operational condition 4 or 5 or defueled, only 3 diesel generators, 1B and 1A, and 0 are required to satisfy the standby AC onsite power requirements for Unit 1.
Surveillance requirements, 4.8.1.1.la and 4.8.1.1.2a.4 shall be performed within 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> prior to removal of the 2A diesel generator from service.
During the 30 day period, the remaining 3 diesel generators will be verified 1 operable at least once per day (in addi-tion to any testing required by Table 4.8.1.1.2-1).
The control circuit for the unit cross-tie circuit breakers between buses 142Y and 242Y shall be temporarily modified to allow the breakers to be closed with the diesel gen-erator feeding the bus.
In the event these conditions are not met, Unit 1 will be brought to HOT SHUTDOWN within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and COLD SHUTDOWN within the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
The provisions of Technical Specification 3.0.4 do not apply.
1The term verify as used in this context means to administratively check by examining logs or other information to determine if certain components are out-of-service for maintenance or other reasons.
It does not mean to per-form the surveillance requirements needed to demonstrate the OPERABILITY of the components.
