BASES 3.0.5 This specification delineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION statements for 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 inoperable 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 e1ectrical power source.

It allows operation to be governed by the time limits of the ACTION statement associated with the Limiting Condition for Operation for the normal or emergency power

source, not the individual ACTIOH statements for each

system, subsystem,

train,

component or device that is determined to be inuperab'le solely because of the inoperability of its normal or emergency power source..

=

For example, Specification 3.8.1.1 requires in part that two emergency diesel generators be

OPERABLE,

'The ACTION statement provides for a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> out-of-service

. time when one emergency diese'I 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 Specification 3.0.5 permit the time limits for continued operation to be consistent with the ACTIOH 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 norma'I or one emergency power source OPERABLE). If they are not satisfied, shutdown 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 Class IE distribution system be OPERABLE.

The ACTION statement provides a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> out-of-service time when both required offsite 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, >>ould also be inoperable..

This would dictate invoking the appli'cable ACTIOti statements for each of the applicable LCOs.

However, the provisions of Specification 3.0.5 per mit the time limits for continued operation to be consistent with the ACTION statement for the inoperable normal power sources

instead, provided the other specified conditions are satisfied.

In this case, this would mean that for one division.the emergency power source must be OPERABLE (as.must be the components supplied by the emergency power source) and all redundant

systems, subsystems,

trains, components and devices in the other division must be OPERABLE, or likewise

. satisfy Specification 3.0.5 (i.e.,

be capable of performing their design functions

..and have.an emergency -power source OPERABLE).

In=-bther words; both emergency power sources must be OPERABLE and all redundant

systems, subsystems,

trains, components and devices in both divisions must also be

OPERABLE, If thes conditions are not satis

ied, shutdown is required in accordance with thiS specification.

In NODES 5 or 6 Specification 3.0.5 is not applicable, and thus the individual ACTIOH statements for each applicable Limiting Condition for Operation in these MODES must be adhered to.

PAGE REVISED DUE TO ADDITIONS ON PREVIOUS PAGE

BASES 3.0.5 This specification deIineates what additional conditions must be satisfied to permit operation to continue, consistent with the ACTION statements for power sources, when a normal or emergency power source is not OPERABLE. It specifically prohibits operation when one division is inoperable because its

nomnal or emergency power source is inoperable and a system, subsystem,

train, component or device in another division is inoperable 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 associated with the Limiting Condition for Operation for the normal or emergency power

source, not the individual ACTION statements

.for each

system, subsystem,

train,

'component or device that is determined to be inoperable solely because of the inoperability of its normal. or emergency power source.

,For example, Specification 3.8.1.1 requires in part that two emergency diesel generators be OPERABLE.

The ACTION statement provides for a 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> 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

ACTIOII statements for each of the applicable Limiting Conditions for Operation.

However, the provisions of Specification 3.0.5.permit the time limits for continued operation to be consistent with the ACTION statement for the inoperab'le 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, shutdown is required-

, in accordance with this specification.

I As a further example, Specification 3,S.l.l requires in part that two physically

~ independent circuits between the offsite transmission network and the onsite Class IE distribution system be OPERABLE.

The ACTION statement provides a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> out-of-service time when both required offsite circuits are not OPERABLE.

If the definition of OPERABLE were applied without consideration cf Specification 3.0.5, all systems, subsystems,

trains, components and devices supplied by the inoperable normal power sources, both of the orfsi te circuits, )mold 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 other specified conditions are satisfied.

In this case, this would mean that for one division the emergency power source must be OPERABLE (as must be the components supplied by the emergency power source) and all redundant

systems, subsystems,

trains, components and devices in the other division must be OPERABLE, or likewise satisfy Specification 3.0.5 (i.e.,

be capable of performing their design functions and have an emergency power source OPEPABLE).

I~ther words, both emergency power sources must be OPERABLE and all redundant

systems, subsystems, tra)ns, components and devices in both divisions must also be OPERABLE, If these conditions are not satisfied, shutdown is required in accordance with thig specification.

In HODES 5 or 6 Specification 3.0.5 is not applicable, and thus the individual ACTION statements for each applicable Limiting Condition for Operation in these HOOES must be adhered to.
