ELECTRICAL POWER SYSTEMS SURVEILLANCE REQUIREMENTS (Continued)

- 4. At least once per 18 months, by verifying that the battery capacity is adequaty to supply and maintain in OPERABLE status all of the actual emergency loads for 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> when the battery is subjected to a battery service test.

5. At least once per 60 months, by verifying that .the battery capacity is at least 80% of the manufacturer's rating when subjected to a performance discharge test. This performance discharge test shall be perfonned subsequent to the satisfactory completion of the required battery service test.

4.8.1.1.2 Each diesel generator shall be demonstrated OPERABLE.

a. At least once per 31 days on a STAGGERED TEST BASIS by:

1. Verifying the fuel level in the day fuel tank,

2. Verifying the fuel level in the fuel storage tank, t

3. Verifying the fuel transfer pump can be started and transfers fuel from the storage system to the day tank, 4 Verifying the diesel starts and can be accelerated to at least 900 RPM, l S. Verifying the generator is synchronized, loaded to greater than or equal to 1500 kw, and operates for greater than or equal to 60 minues, and

6. Verifying the diesel generator is aligned to provide standby power to the associated emergency busses,

b. At least once each 92 days by verifying that a sample of diesel fuel from the fuel storage tank is within the acceptable limits specified in Table 1 of ASTM D975-68 when checked for viscosity, water and sediment.

c. At least once per 184 days in lieu of surveillance 4.8.1.1.2.a.4 by verifying the diesel starts from ambient condition, without prelubing, and accelerates to at least 900 rpm in less than or equal to 10 seconds.

d. At least once per 18 months, by:

1. Subjecting the diesel to an inspection in accordance with procedures prepared in conjunction with its manufacturer's recomendations for this class of standby service, 8610210143 861015 PDR ADOCK 05000302 p PDR CRYSTAL RIVER - UNIT 3 B 3/4 8-1

..e, 3/4.8 ELECTRICAL POWER S7 STEMS BASES The OPERABILITY of the A.'C. and D.C. power sources and associated distribution 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 SD.

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 consistent with the initial condition assumptions of the safety analyses and are based upon maintaining at least one of each of the onsi te . 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.

For the purposes of the diesel generator start testing, " ambient condition" means the diesel engine coolant and oil are being continuously circulated and maintained at a temperature consistent with the manufacturer's recommendations.

Except for the 184-day cold fast diesel start, all preplanned diesel generator starts may be preceeded by prelube and or other warmup procedures recommenaed by the manufacturer. Addi tionally, except for the 18-month diesel start, all preplanned diesel generator runs may be gradually loaded, reloaded and unloading as reconenended by the manufacturer. The purpose of following these manufacturer's recommendations is to minimize the mechanical and thennal stress and wear on the diesel engine.

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 and refueling condition for extended time periods and 2) sufficient instrumentation and control capabili ty is available for monitoring and maintaining the facility status.
