( RAS E., i The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient power will be svailable to supply the safety related equipment required for 1) the safe l 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 Adc/ requirements of 10 CFR Part 50, Appendix A General Design Criteria 17.
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation commensurate with the levr ' of degradation. The OPERABILITY of the power 1ources are consistent wi' , the initial condition assumptions of the accident analyses and are based upon maintaining at lecst one of each of the onsite A.C. and D.C. power sources and associated distribution systems OPERABLE during accident conditions coincident with an 3ssumed loss of offsite power and single failure of the other onsite A.C. source.
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 capability is available for monitoring and maintaining the facility states, t The ACTION requirements for LCOs 3.8.1.2 and 3.8.2.2 are associated with the perfonnance of Surveillance 4.8.1.1.2.d.1 on No.12 emergency diesel generator with Unit 1 shutdown and Unit 2 at power. This requires that No.
l 31 emergency dic el generator be aligned to Unit 2. The actions specified reduce the probability of a loss of offsite power by requiring the availability of two offsite power circuits. A temporary diesel is available which has sufficient capacity to carry all required shutdown loads. This ACTION only applies to the perfonnance of Surveillance 4.8.1.1.2.d.1 on No. 12 emergency diesel generator. Perforu nce of Surveillance 4.8.1.1.2.d.1 on No.11 emergency diesel generator would not violate the LCOs for 3.8.1.2 and 3.8.2.2 because the No. 12 emergency diesel generator may be aligned to either unit.

opposite unit under normal shutdown conditions with a diesel generator load of 2,500 Kw. !
1 Additionally, the OPEllAlllLI'lY of No. 21 Fuel Oil Storage Tank ensures that in the event of a loss of offsite power, concurrent with a loss of the non. bunkered fuel oil storage tank (tornado / missile i l
event), at least 7 days of fuel oil will be available for operation of one diesel generator on each unit, assurning both diesel generators are loaded to 2,500 Kw. j

The OPERABILITY of the A.C. and D.C. power sources and associated '
distribution systems during operation ensures that se Nient power will be available shutdowntoofsupply the safety)related the facility equipment and 2 the mitigation requirwofforaccident and control 1) the safe conditions within the facility. The minimum specified independent and redundant A.C. and D.C. power sources and distribution systems satisfy the N/\ requirements of 10 CFR Part 50, Appendix A. General Design Criteria 17.
D EW F;' ~>
The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation connensurate with the level of degradation. The OPERABILITY of the power sources are consistent with the initial condition assumptions of the accident analyses and are based upon maintaining at least one of each of the 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 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 capability is available for monitoring and maintaining the facility status.
Y The ACTION requirements for LCOs 3.8.1.2 and 3.8.2.2 are associated with the perfomance of Surveillance 4.8.1.1.2.d.1 on No.12 emergency diesel generator with Unit 2 shutdown and Unit 1 at power. This requires that No.
21 emergency diesel generator be aligned to Unit 1. The actions specified reduce the probabilicy of a loss of offsite power by requiring the availability of two offsite power circuits. A temporary diesel is available which has sufficient capacity to carry all required shutdown loads. This ACTION only applies to the perfomance of Surveillance
. 4.8.1.1.2.d.1 on No.12 emergency diesel generator. Performance of Surveillance 4.8.1.1.2.d.1 on No. 21 emergency diesel generator would not -
violate the LCOs for 3.8.1.2 and 3.8.2.2 because the No. 12 emergency diesel generator may be aligned to either unit.

'Ihe OPEllAllllflY of No. 21 and No.11 Fuel Oil Storage Tanks ensures that at least 7 days of fuel oil will be reserved below the internal tank standpipes for operation of one diesel generator on cach unit, assuming one unit under accident conditions with a diesel generator load of 3,(XX) Kw, and the opposite unit under norrnal shutdown condition with a diesel generator load of 2,5(X) Kw.
Additionally, the OPEllAltilIIY of No. 21 Fuel Oil Storage Tank ensures that in the event of a loss l l
of of fsite power, concurrent with a loss of No.11 Fuel Oil Storage Tank (tornado /rnissile event), at least 7 days of fuel oil will be availhhle for operation of one diesel generator on each unit, assuming both diesel generators are loaded to 2,$tKJ Kw.
The OPEllAllllJIY of the fuel oil day tanks ensures that at least one hour of diesel generator operation is available without rnakeup to the da; tanks, assurning the associated diesel generator is loaded to 3,250 Kw.
