.APPLICABILITY BASKS

~

The same pr inciple applies with regard to the allowable outage Mme limits of the ACTION requirements, if compliance with the ACTION requirements for one specification results in entry into a

MODE or condition of operation for another specification in which the requirements of the Limiting Condition for Operation are not met.

If the new specification becomes applicable in less time than specified, the difference may be added to the allowable outage time limits of the second specification.

However, the allowable outage time limits of ACTION requirements for a higher MODE of operation may not be used to extend the allowable outage time that is applicable when a Limiting Condition for Operation is not met in a lower MODE of operation.

The shutdown requirements of Specification 3.0.3 do not apply in MODES 5

and 6, because the ACTION requirements of individual specifications define the

, remedial measures to be taken.

3.0.4 This specification establishes limitations on MODE changes when a Limiting Condition for Operation is not met.

It precludes placing the facility fn a higher,')ODE of operation when the requirements for a Limiting Condition for Operation are not met and continued noncompliance to these conditions would result in a shutdown to comply with the ACTION requirements if a change in MODES were permitted.

The purpose of this specification'is to ensure that facility operation is not initiated or that higher MODES of operation are not entered when corrective action is being taken to obtain compliance with a specification by restoring equipment to OPERABLE status or parameters to specified limits.

Compliance with ACTION requirements that permit continued operation of the facility for an unlimited period of time provides an accept-able level of safety for continued operation without regard to the status of the plant before or after a

MODE change.

Therefore, in this case, entry into an OPERATIONAL MODE or other specified condition may be made in accordance with the provisions of tHe ACTION requirements.

The provisions of this specification should not, however, be interpreted as endorsing the failure to exercise good practice in restoring systems or components to OPERABLE status before plant startup.

When a shutdown is required to comply with the ACTION requirements, the provisions of Specification 3.0,4 do not apply because they would delay placing the facility in a lower MODE of operation.

Exceptions to this provision have been provided,or a limited number of specifications when startup with inoperable equipment would not affect plant sa ety.

These exceptions are stated in the ACTION statements of the appro-

. riate specifications.

sr 3/4.8 ELECTRICAL POWER SYSTEMS BASES The OPERABILITY of the A.C. and O.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 faci lity.

The minimum specified independent and redundant A.C.

and O.C.

power sources and distribution systems satisfy the requirements of General Oesign 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 consis-tent 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.

When one diesel generator is inoperable, there is an additional 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, and that the steam-driven auxiliary feedwater pump is OPERABLE.

This requirement is intended to provide'ssurance 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 requi rements needed to demonstrate the OPERABILITY of the component.

Ambient conditions are the normal standby conditions for the diesel engines.

Any normally running warmup systems should be in service and operating, and manufacturer's recommendations for engine oi 1 and water temperatures and other parameters should, be followed.

s The OPERABILITY of the minimum specified A.C.

and O.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.

The Surveillance Requirements for demonstrating the OPERABILITY of the diesel generators are in accordance with the recommendations of Regulatory Guide 1. 108, "Periodic Testing of Oiesel Generator Units Used as Onsite Electric Power Systems at Nuclear Power Plants,"

Revision 1, August 1977, Regulatory Guide 1. 137, "Fuel Oil Systems for Standby Oiesel Generators,"
