3 /4. 0 APPLICABILITY LIMITING CONDITION FOR OPERATION 3.0.1 Limiting Conditions for Operation and ACTION requirements shall be applicable during the OPERATIONAL MODES or other conditions specified for each specification.

3.0.2 Adherence to the requirements of the Limiting Condition for Operation and/or associated ACTION within the specified time interval shall constitute compliance with the specification.

In the event the Limiting r

Condition for Operation is restored prior to expiration of the specified i

time interval, completion of the ACTION statement is not required.

3.0.3 In the event a Limiting Condition for Operation and/or associated ACTION requirements cannot be satisfied because of circumstances in excess of those addressed in the specification, within one hour action shall be initiated to place the unit in a MODE in which the Specification does not apply by placing it, as applicable, in:

1.

At least HOT STAND 8Y within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , 2.

At least HOT SHUTDOWN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , and 3.

At least COLD SHUTOOWN within the subsequent 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

Where corrective measures are completed that permit operation under the

(..

ACTION requirements, the ACTION may be taken in accordance with the specified time limits as measured f rom the time of f ailure to meet the Limiting condition for Operation.

Exceptions to these requirements are i

stated in the individual Specifications.

This Specification is not applicable in MODES S or 6.

[I.O.4 Entry into an OPERATIONAL MODE or other specified applicability

}

condition shall not be made unless the conditions of the Limiting Condition NU for Operation are met without reliance on provisions contained in the 1 ACTION statements unless otherwise excepted.

This provision shall not prevent passage through OPERATIONAL MODES as required to comply with ACTION statements.

3.0.5 When a system, subsystem, train, component or device is determined to be inoperable solely because its emergency power source is inoperable, or solely because its normal power source is inoperable, it may be considered OPERABLE for the purpose of satisfying the requirements of its applicable Limiting Condition for Operation, provided:

(1) its corresponding normal or emergency power source is OPERABLE; and (2) all of its redundant system (s), subsystem (s), train (s), component (s) and device (s) are OPERABLE, or likewise satisfy the requirements of this specification.

Unless both conditions (1) and (2) are satisfied, the unit shall be placed in at least HOT STANDBY within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months , in at least HOT SHUT 00WN within the next 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months , and in at least COLD SHUTOOWN within the following 30 hours3.472222e-4 days 0.00833 hours 4.960317e-5 weeks 1.1415e-5 months .

Specification 3.0.1 through 3.0.4 establish the general requirements applicable to Limiting conditions for Operation.

o These requirements are based on the requirements for Limiting Conditions for Operation stated in the Code of Federal Regulations,10 CFR 50.36(c)(2):

p L't

_ " Limiting conditions for operation are the lowest functional capability i

or perfomance levels of equipment reovired for safe operation of the L

i Conditions for Operation is required for safe operation of the facility. The i

L ACTION requirements establish those remedial measures that must be taken

, within specified time limits when the requirements of a Limiting Condition for Operation are not met.

g g

- There are two basic types of ACTION requirements. The first specifies the 7 remedial measures that pemit continued operation of the facility which is not

. further restricted by the time Ifmits of the ACTION requirements.

- <.j In this case, conformance to the ACTION requirements provides an acceptable level of l safety for unlimited continued operation as long as the ACTION reovirements continue to be met. The second type of ACTION requirement specifies a time L

uj i

l limit in which confomance to the conditions of the Limiting Condition for

. 0peration must be met. This time limit is the allowable outage time to

~ l restore an inoperable system or component to OPERABLE status or for restoring

~

~i parameters within specified limits.

If these actions are not completed within i

h_ -

the allowable outage time limits, a shutdown is required to place the facility in a MODE or condition in which the specification no longer applies.

It is not intended that the shutdown ACT!0N requirements be used as an o y

convenience which pemits (routine) voluntary removal of a system (perational i

allowed to prepare for an orderly shutdown before initiating a change in plant i --

The time limits of Specification 3.0.3 allow 37 hours4.282407e-4 days 0.0103 hours 6.117725e-5 weeks 1.40785e-5 months for the plant to be in the COLD SHUTDOWN MODE when a shutdown is required during the POWER MODE of i

If the plant is in a lower MODE of operation when a shutdown is required, the time limit for reaching the next lower MODE of operation ap-i plies.

However, if a lower MODE of operation is reached in less time than P

R 1,_ MODE, is not reduced. allowed, the total allowable time to reach COLD SHUTDOWN o l

For example, if HOT STANDBY is reached in 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , the l time allowed to reach HOT SHUTDOWN is the next 11 hours1.273148e-4 days 0.00306 hours 1.818783e-5 weeks 4.1855e-6 months because the total time!

oi to reach HOT SHUTDOWN is not reduced from the allowable limit of 13 hours1.50463e-4 days 0.00361 hours 2.149471e-5 weeks 4.9465e-6 months .

F

,; ~

Therefore, if remedial measures are completed that would pemit a return to l

POWER operation, a wnalty is not incurred by having to reach a lower MODE of H operation in less tian the total time allowed.

m.

F The same principle applies with regard to the allowable outage time 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 h

~

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 i1 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.

i z

1 The shutdown requirements of Specification 3.0.3 dB not apply in MODES S and 0

1~

6, because the ACTION requirements of individual specifications define the l,-

remedial measures to be taken.

_ Specification 3.0.4 establishes limitations on MODE changes when a Limiting condition for Operation is not met.

It precludes placing the facility in a

+

p higher MODE of operation when the requirements for a Limiting Condition for C

Operation are not met and continued noncompliance to these conditions would I

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 LJ ~, facility operation is not initiated or that higher MODES of operation are not L

j entered when corrective action is being taken to obtain compliance with a H q specification by restoring equipment to 0PERABLE status or parameters to specified limits. Cospliance with ACTION requirements that perwit continued q operation of the facility for an unlimited period of time provides an accept-l 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 trith the provisions of the ACTION requirements. The provisions of this 3

i 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.

1 Exceptions to this provision have been provided for a limited number c

of specifications when startup with inoperable equipment would not af fect plant safety. These exceptions are stated in the ACTION statements of l-

,the appropriate specifications, l.

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 associ-ated 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 state--

ments for each system, subsystem, train, component or device that is determined to be inoperable solely because of tne 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 hours8.333333e-4 days 0.02 hours 1.190476e-4 weeks 2.7396e-5 months out-of-service time when one emergency diesel generator is not OPERABLE.

If the definition of OPERABLE were applied without considera-tion 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 state-ments for each of the applicable Limiting Conditions for Operation.

However, the provisions of Specification 3.0.5 permit the time limits I 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, shutdown is required in accordance with this specification.

As a f urther example, Specification 3.8.1.1 requires in part that two

associated with plant shutdown as well as startup.

J w -

Under the provisions of this specification, the applicable Surveillance Requirements must be performed within the specified surveillance interval to ensure that the Limiting Conditions for Operation are met during initial

,l plant startup or following a plant outage.

When a shutdown is required to comply with ACTION requirements, the provisions l

~~

of Specification 4.0.4 do not apply because this would delay placing the facility in a lower MODE of operation.

~

Specification 4.0.5 establishes the requirement that inservice inspection of 4

A5M Code class 1, 2. and 3 components and inservice testing of ASME Code Class 1, 2, and 3 pumps and valves shall be performed in accordance with a periodically updated version of Section XI of the ASME Boiler and Pressure vessel Code and Addenda as required by 10 CFR 50.55a. These requirements apply except when relief has been provided in writing by,the Commission.

This specification includes a clarification of the frequencies for perfoming i-the inservice inspection and testing activities required by Section XI of the ASME Boiler and Pressure Vessel Code and applicable Addenda. - This clarification

-is provided to ensure consistency in surveillance intervals throughout the Technical Specifications and to remove any ambiguities relative to the e

x,

frequencies for perfoming the required inservice inspection and testing activities.

_m. y 1 Under the terms of this specification, the more restrictive requirements of i

the Technical Specifications take precedence over the ASME Poiler and Pressure 4

Vessel Code and applicable Addenda. The requirements of Specification 4.0.4

- 4 to perform surveillance activities before entry into an OPERATIONAL MODE or other specified condition takes preceder.ce over the ASME Boiler and Pressure i

Vessel Code provision which allows pumps and valves to be tested up to one week after return to normal operation. The Technical Specification definition of OPERABLE does not allow a grace period before a component, that is not capeble of performing its specified function, is declared inoperable and takes

~'

precedence over the ASME Boiler and Pressure Vessel Code provision which allows a valve to be incapable of perforsing its specified function for up to 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months before being declared inoperable.
