on the time of the initial loss of the remaining inoperable offsite a.c. circuit. A successful test (s) of diesel OPERABILITY per Surveil-lance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.a.5 performed under

{ this ACTION Statement for the OPERABLE diesels satisfies the diesel generator test requirement for ACTION Statement a.

f. With two of the above required diesel generators inoperable, demonstrate the OPERABILITY of two offsite A.C. circuits by performing the require-ments of Specification 4.8.1.1.1.a. within I hour and at least once per 8 hours9.259259e-5 days 0.00222 hours 1.322751e-5 weeks 3.044e-6 months thereafter; restore at least one of the inoperable diesel generators to OPERABLE status within 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months or be in at least HOT STANDBY within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months .

A successful test of diesel DPERABILITY per Surveillance Requirements 4.8.1.1.2.a.4 and 4.8.1.1.2.a.5 performed i under this ACTION Statement for a restored to OPERABLE diesel satisfies j the diesel generator test requirements of ACTION Statement b.

a. Determined OPERABLE at least once per 7 days by verifying correct breaker alignments, and indicated power availability.

4.8.1.1.2 Each diesel generator shall be demonstrated OPERABLE:

a. In accordance with the frequency specified in Table 4.8-1 on a STAGGERED TEST BASIS by:

1) Verifying the fuel level in the' day tank (LI-9018, LI-9019),

2) Verifying the fuel level in the fuel storage tank (LI-9024, l LI-9025),

3) Verifying the fuel transfer pump starts and transfers fuel from the storage system to the day tank,

4) Verifying the diesel starts and that the generator voltage and frequency are 4160 + 170, -135 volts and 60 + 1.2 Hz within 11.4 seconds" after the start signal. The dTesel generator shall be started for this test by using one of the following signals:

3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.1, 3/4.8.2, and 3/4.8.3 A.C. SOURCES, D.C. SOURCES, and DNSITE POWER DISTRIBUTION The OPERABILITY of the A.C. and D.C power sources and associated distribu-tion systems during operation ensures that sufficient power will be available to supply the safety related equipment required for: (1) the safe shutdown of the facility, and (2) the mitigation and control of accident conditions within the facility. The minimum specified independent and redundant A.C. and D.C.

power sources and distribution systems satisfy the requirements of General Design Criterion 17 of Appendix A to 10 CFR Part 50.

4 The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the level of degradation. The OPERABILITY of the power sources are con-sistent with the initial condition assumptions of the safety analyses and are based upon maintaining at least one redundant set of onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an assumed loss of offsite power and single failure of the other onsite A.C. source. The A.C. and D.C. source allowable out of-service times are based on Regulatory Guide 1.93, " Availability of Electrical Power Sources," December 1974 and Appendix A to Generic Letter 84-15, " Proposed Staff Position to Improve and Maintain Diesel Generator Reliability." When one diesel generator is inoperable, there is an additional ACTION requirement to verify that all required systems, subsystems, trains, components and devices, that depend on the remaining OPERABLE diesel generator as a source of emergency power, are also OPERABLE, and that the steam-driven auxiliary feedwater pump is OPERABLE. This requirement is intended to provide assurance that a loss-of- l cffsise power event will not result in a complete loss of safety function of critical systems during the period one of the diesel generators is inoperable. i ine term. verify, as used in this context means to administratively check by '

examining logs or other inf ormation to determine if certain components are out-of service for maintenance or other reasons. It does not mean to perform the Surveillance Requirements needed to demonstrate the OPERABILITY of the component.

C The OPERABILITY of the minimum specified A.C. and D.C. power sources and associated distribution systems during shutdown and refueling ensures that:

(1) the facility can be maintained in the shutdown or refueling condition for atended time periods, and (2) sufficient instrumentation and control capa-bility is available for monitoring and maintaining the unit status.

The Surveillance Requirements for demonstrating the OPERABILITY of the c.iesei generators are based on the recommendations of Regulatory Guides 1.9, ;

Revision 2 " Selection of Diesel Generator Set Capacity for Standby Power Secolies," December, 1979; 1.103, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants," Revision 1 August 1977; and 1.137, " fuel-Oil Systems for Standby Diesel Generators."

Insert page B 3/4 8-1 The ACTION times specified for an inoperable automatic load sequencer are based on the times allowed when a combination of one diesel generator and one offsite circuit is inoperable. This conservatively addresses any consequential effects of an inoperable '

load sequencer on other engineered safety features and avoids having to evaluate the ACTION based on table 3.3-2.
