- 420 volts and 60 i 1.2 Hz within 10 seconds after the start signal. The diesel generator shall be started for this test by using one of the following signals:
a) Manual, b) Simulated loss-of-offsite power by itself.
c) Simulated loss-of-offsite power in conjunction with an ESF actuation test signal.
d) An ESF actuation test signal by itself.

- 6. Verifying the diesel generator is aligned to provide standby power to the associated emergency busses.
- 7. Verifying the pressure in all diesel generator air start receivers to be greater than or equal to 215 psig.
- All diesel generator starts for the purpose of this Surveillance Requirement may be preceded by an engine prelube period. The diesel generator start (10 sec) from ambient conditions shall be performed at least once per 184 days in these surveillance tests. All other engine starts for the purpose of this surveillance testing may be preceded by other warmup procedures recommended by the manufacturer so that the mechanical stress and wear on the diesel engine is minimized.

- M.4 28 ELECTRICAL p0WER SYSTEMS I BASES 3/4.8.1. 3/4.8.2 and"3/4.8.3 A.C.' SOURCES. D.C. SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS 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 Criteria 17 of Appendix "A" to 10 CFR 50.
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 is consistent with the initial condition assumptions of the safety analyses and is based upon maintaining at least one of the onsite A.C. and the corresponding 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. or D.C. source.
The A.C. and D.C. source allowable out-of-service times are based, in t part, on Regulatory Guide 1.93, " Availability of Electrical Power Sources",
December 1974. When one diesel generator is inoperable, there is an additiont 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. This requirement is intended to provide assurance that a loss of offsite 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. The 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 perform the surveillance requirements needed to demonstrate the OPERABILITY of the component.
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 ;
extended time periods and (2) sufficient instrumentation and control 1 capability is available for monitoring and maintaining the unit status. !
The surveillance requirements for demonstrating the OPERABILITY of the ,
diesel generators are in accordance with the recommendations of Regulatory l Guide 1.9, " Selection of Diesel Generator Set Capacity for Standby Power l Supplies", December 1979; Regulatory Guide 1.108, " Periodic Testing of Diesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power i Plants", Revision 1, August 1977; and Regulatory Guide 1.137, " Fuel-0il l Systems for Standby Diesel Generators", Revision 1, October 1979, as modified by Generic Letter 94-01, " Removal of Accelerated Testing and Special Reporting Requirements for Emergency Diesel Generators," May 1994. l FERMI - UNIT 2 B 3/4 8-1 Amendment No.
