1 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 I shutdown of the facility and 2) the mitigation and control of accident l conditions within the facility. The minimum specified independent and l redundant A.C. and D.C. power sources and distribution systems satisfy the I requirements of 10 CFR Part 50. Appendix A, General Design Criteria 17. I l

The OPERABILITY of No. 21 and No. 11 Fuel Oil Storage Tanks ensure that at least 7 days of fuel oil will be reserved below the internal tank standpipes for operation of one diesel generator on each unit, as ing one unit under accident conditions with a diesel generator load of . Kw, and the opposite unit under nonnal shutdown conditions with a diese1%@h generator load af/E555JKw. Additionally, the OPERABILITY of No. 21 Fuel h000,f 011 Storage Tanrensures that in the event of a loss of offsite power, concurrent with a loss of the non-bunkered fuel oil storage tank 4

(tornado / missile event), at least 7 days of fuel oil will be available for operation of one diesel gener tor on each unit, assuming both diesel generators are loaded to ,

t .-

The OPERABILITY of the fuel oil day tanks ensures that at least one hour of diesel generator operation is available without makeup to_ the day tanks, assuming: 1 :::ickd dibel g: . 7:t;r 4 ::: :: Tc 3,25@ t The ACTION requirements specified for the levels of degradation of the power sources provide restriction upon continued facility operation

. the onsite A.C. and D.C. power sources and associated distribution systems 0PERABLE 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.

INSERT E Surveillance 4.8.1.1.2.d.3.c demonstrates that diesel generator noncritical protective functions are bypassed on a Safety Injection Actuation Signal. The diesel generator availability to mitigate the Design Basis Accident is more critical than protecting the engine against problems that are not immediately detrimental to emergency operation of the diesel generator. The automatic trips that are required to be bypassed on a Safety Injection Actuation Signal are identified in the Updated Final Safety Analysis Report.

Surveillance 4.8.1.1.2.a.5 for No. l A Emergency Diesel Generator ensures that at least once per month the diesel generator is loaded to greater than the load required during accident conditions. For No. IB Emergency Diesel Generator, Surveillance 4.8.1.1.2.a.5 verifies that this diesel generator is capable of synchronizing with the offsite electrical system and accepting loads greater than or equal to 90 percent of the diesel generator's continuous rating for a period of greater than or equal to 60 minutes.

Surveillance 4.8.1.1.2.d.4 ensures that at least once per REFUELING OUTAGE each diesel generator is loaded to greater than the load required during accident conditions.

BASES l The OPERABILITY of the A.C. and D.C. power sources and associated i distribution systems during operation ensures that sufficient power will be l

available to supply the safety related equipment required for 1) the safe j shutdown of the facility and 2) the mitigation and control of accident i conditions within the facility. The minimum specified independent and

! redundant A.C. and D.C. power sources and distribution systems satisfy the rements of 10 CFR Part 50 Appendix A General Design Criteria 17.

i t 3000 3500 i r e OPERABILITY of No. 21 and No. 11 Fuel Oil Storage Tanks ensures that l 1 east 7 days of fuel oil will be reserved below the internal tank standpipes for operation of one diesel generator on each unit, i one j unit under accident conditions with a diesel generator load of Kw,

and the oppositt der normal shutdown conditions with a d ese i generator load Kw. Additionally, the OPERABILITY of No. 21 Fuel l Oil Storage Tank res that in the event of a loss of offsite power,

concurrent with a loss of No. 11 Fuel Oil Storage Tank (tornado / missile j event), at least 7 days of fuel oil will be available for operation of one

! dies enerator on each unit, assuming both diesel generators are loaded to , Kw. goco i The OPERABILITY of the fuel oil day tanks ensures that at least one hour of i diesel generator operation is available without makeup t the day tanks

( assuming the associated diesel generator is loaded to w.

j Tha ACTION requirements specified for the levels of degradation of the j power sources provide restriction upon continued facility operution commensurate with the level of degradation. The OPERABILITY of the powr i sources are consistent with the initial condition assumptions of the i accident analyses and are based upon maintaining at least one of each of i the onsite A.C. and D.C. power sources and associated distribution systems j OPERABLE during accident conditions coincident with an assumed loss of i 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 J

1) the facility can be maintained in the shutdown or refueling condition 4 for extended time periods and 2) sufficient instrumentation and control capability is available for monitoring and maintaining the facility status.

! Surveillance 4.E.1.1.2.d.3.c demonstrates that diesel generator noncritical protective functions are bypassed

. on a Safety injection Actuation Signal. The diesel generator availability to mitigate the Design Basis l Accident is more critical than protecting the engine against problems that are not immediately detrimental J to emergency operation of the diesel generator. The automatic trips that are required to be bypassed on a 7

Safety Injection Actuation Signal are identified in the Updated Final Safety Analysis Report.

i i Surveillance 4.8.1.1.2.a.5 verifies that the diesel generators are capable of synchronizing with the offsite

~

electrical system and accepting loads greater than or equal to 90 percent of the diesel generator's continuous rating for a period of greater than or equal to 60 minutes. Surveillance 4.8.1.1.2.d.4 ensures that at least once per REFUELING OUTAGE the diesel generator is loaded to greater than the load ,

i required during accident conditions.

BASES M CTION re d ements I LCOs 3.8 1 2 and 3.8.2.2 are associated with I the performance '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 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 performance of Surveillance 4.8.1.1.2.d.1 on No. 12 emergency diesel generator.

Perfomance 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.
