DAVIS-BESSE, UNIT 1 3/4 0-2 Amendment No. 7J.JM,145
3/4.0_ APPLICABILITY BASES The specifications of this section provide the general requirements applicable to each of the Limiting Conditions for Operation and Surveillance Requirements within Section 3/4.
3.0.1 This specification defines the applicability of each specification in terms of defined OPEPATIONAL MODES or other specified conditions and is provided to delineate specifically when each specification is applicable.
3.0.2 This specification defines those conditions necessary to constitute compliance with the terms of an individual Limiting Condition for Operation and associated ACTION requirement.
3.0.3 This specification delineates the ACTION to be taken for circumstances not directly provided for in the ACTION statements and whose occurrence would violate the intent of the specification.
For example, Specification 3.5.1 requires each Reactor Coolant System core flooding tank to be OPERABLE and provides explicit ACTION requirements if one tank is inoperable.
Under the terms of the Specification 3.0.3, if more than one tank is inoperable, within one hour measures must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.
As a' further example Specification 3.6.2.1 requires two Containment Spray Systems to be OPERABLE and provides excplicit ACTION requirements if one spray system is inoperable. Under the terms of Specification 3.0.3, if both of the required Containment Spray Systems are inoperable, within one hour measures must be initiated to place the unit in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, in at least HOT SHUTDOWN within the following 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />, and in at least COLD SHUTDOWN in the following 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
It is assumed that the unit is brought to the required MODE within the required times by promptly initiating and carrying out the appropriate ACTION statement.
3.0.4 This specification provides that entry into an OPERATIONAL MODE or other specified applicability condition must be made with (a) the full complement-of required systems, equipment-or components OPERABLE and (b) all other parameters as specified in the Limiting Conditions for Operation being met without regard for allowable deviations and out of service provisions contained in the ACTION statements.
The intent of this provision is to insure that facility operation is not initiated with either required equipment or systems inoperable or other specified limits being exceeded.
Exceptions to this provision have been provided for a limited numbei of specifications when startup with inoperable equipment would not affeot plant safety. These exceptions are stated in the ACTION statements of the apprapriate specifications.
DAVIS-BESSE, UNIT 1 B 3/4 0-1 Amendment No. 7J,163
APPLICABILITY BASES 3.0.5 This specificaticn delineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION statements fur power sources, when a normal or emergency power source is not OPERABLE.
It specifically prohibits operation when one division is inoperable because its normal or emergency power source is inoperable and a system, subsystem, train, component or device in another division is inoperabic for another reason.
The provisions of this specification permit the ACTION statements associated with individual systems, subsystems, trains, components,-or-devices to be consistent with the ACTION statements of the associated electrical power source.
It allows operation to be governed by the time limits of the ACTION statement asso:iated with the Limiting Condition for Operation for the normal or emergency power source, not the individual ACTION statements for each system, subsystem, train, compcnent or device that is determined to be inoper-able solely because of the inoperability of its normal or emergency power -
source.
For exaaple, Specification 3.8.1.1 requires in part that two emergency diesel generators be OPERABLE.
The ACTION statement provides for a 72-hour out-of-service time when one emergency diesel generator is not OPERABLE.
If the definition of OPERABLE were applied without consideration of Specification 3.0.5, all systems, subsystems, trains, components and devices supplied by the inoperable emergency power source would also be inoperable. This would dictate invoking the applicable ACTION statements for each of the applicable Limiting Conditions for Operation.
However, the provisions of Speci fication 3.0.5 -
permit the time limits for continued operation'to be consistent with the ACTION statement for the inoperable emergency diesel generator instead, provided the other specified conditions are satisfied.
In this case, this would mean that the corresponding normal power source must be OPERABLE, and all redundant systems, subsystems, trains, components, and devices must be OPERABLE, or otherwise satisfy Specification 3.0.5 (i.e., be capable of performing their design function and have at least one normal or one emergency power source OPERABLE).
If they are not satisfied, action is required in accordance with this specification.
As a further example, Specification 3.8.1.1 requires in part that two physically independent circuits between the offsite transmission network and the onsite i
Class 1E distribution system be OPERABLE.
The ACTION statement provides a
)
24-hour out-of-service time when both required of fsite circuits are not OPERABLE.
If the definition of OPERABLE were applied without' consideration of Specification 3.0.5, all' systems, subsystems, trains, components and devices supplied by the inoperable normal' power sources, both of the offsite circuits, would also be inoperable. This would_ dictate invoking the applicable ACTION statements for each of the applicable LCOs.
However, the provisions of Specification 3.0.5-permit the time limits for continued operation to be consistent with the ACTION statement for the inoperable normal power sources instead, provided the DAVIS-BESSE, UNIT 1 B 3/4 0-la Amendment No. 71 correction letter 8/9/84
