- 1 ELECTRICAL POWER SYSTEMS A.C. SOURCES - SHUT 00WN LIMITING CONDITION FOR OPERATION 3.8.1.2 As a minimum, the following A.C. electrical power sources shall be OPERABLE:

a. One circuit between the offsite transmission network and the onsite Class IE distribution system, and
b. Two diesel generators, one of which shall be diesel generator A or diesel generator B, each with:

INSERP 2

1. A separate fuel oil day tank containing a minimum of 200 gallons of fuel.
2. A fuel storage system consisting of two storage tanks containing a minimum of 48,800 gallons of fuel,
3. A separate fuel transfer pump for each storage tank.

APPLICABILITY: OPERATIONAL CONDITIONS 4, 5 and *.

ACTION:

a. With less than the above required A.C. electrical power sources OPERABLE, suspend CORE ALTERATIONS, handling of irradiated fuel in the secondary containment, operations with a potential for draining the reactor vessel and crane operations over the spent fuel. storage pool when fuel assemblies are stored therein. In addition, when in OPERATIONAL CONDITION 5 with the water level less than 22'-2" above the reactor pressure vessel flange, immediately initiate corrective action to restore the required power sources to OPERABLE status as soon as practical.
b. The provisions of Specification 3.0.3 are not applicable.

SURVEILLANCE REQUIREMENTS 4.8.1.2 At least the above required A.C. electrical power sources shall be demonstrated OPERABLE per Surveillance Requirements 4.8.1.1.1, 4.8.1.1.2, and 4.8.1.1.3, except for the requirement of 4.8.1.1.2.a.5.

3/4.8 ELECTRICAL POWER SYSTEMS BASES 3/4.8.l u 3/4.8.2 and A.C. SOURCES, D.C. SOURCES and DNSITE POWER 3/4.8.3 DISTRIBUTION SYSTEMS The OPERABILITY of the A.C. and D.C. power sources and associated distribution systems during operation ensures that sufficient powlir will be available to supply the safety related equipment required for (1) the safe shutdown of the facility and (2) the mitigation and contrcl 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 are con-sistent with the initial condition assumptions of the safety analyses and are 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 loes of offsite power and single. failure of the other onsite A.C. or D.C. source.

The A.C. and C.C. source allowable out of-service times are based on Regulatory Guide 1.93, " Availability of Electrical Power Sources", December 1974 as modified by plant specific analysis and diesel generator manufacturer recommendations. Wh::n two diesel generators are. inoperable, there is an'addi-tional ACTION requirement to verify that all required systems, susbsystems, trains, components and devices, that depend on the; remaining OPERABLE diesel generators 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 two or more of the diesel generators are inoperable. The term verify as used in this context means to administrative 1y 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 lfor extended time periods and (2) sufficient instrumentation and control 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.

Guide 1.9, " Selection of-Diesel Generator Set Capacity for Standby Power o Supplies",' March 10, 1971, Regulatory Guide 1.108, " Periodic Testing of Diesel L Generator Units Used as.Onsite Electric Power Systems.at. Nuclear Power Plants",

Revision 1, August 1977 and Regulatory Guide 1.137" Fuel-Oil.' Systems for'Standb Diesel-Generators". Revision 1, October'1979 as: modified by wplant =-
