3.0.1 This specification states the applicability of each sp fication in terms of fined OPERATIONAL CONDITION or other specified app ability condition and provided te delineate specifically when each cification is applicable.

3.0.2 This spe fication defines those conditions cessary to constitute compliance with the te s of an individual Limiting Co tion for Operation and associated ACTION re irement. ,

3.0.3 This specificatio delineates the me ures to be taken for those circumstarices not directly prov ed for in the TION statements and whose occurrence would violate the inte of the s cification. For, example, Specifi-cation 3.7.2 requires two main cont I roo air conditioning subsystems to be <

OPERABLE and provides explic'it ACTION e irements if one subsystem is inoperable.

Under the requirements of Specificatio .0.3, if both of.the required subsystems are inoperable, measures must be int ate within 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months to place the unit in at least STARTUP within the next 6 ours, i t least HOT SHUT 00WN within the following 6 hours6.944444e-5 days 0.00167 hours 9.920635e-6 weeks 2.283e-6 months and in COLD SH OWN within o subsequent 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months .

3.0.4 This specificati provides that ent nto an OPERATIONAL CON 0!

4.0.1 This specification provides that surv6111ance activities, necessa to sure the Limiting Conditions for Operation are met, will be performed l durin the OPERATIONAL CONDITIONS or other conditions for which the Limiti j Conditi s for Operation are applicable. Provisions for additional surv lance activitie to be parfurmed without regard to the applicable OPERATIO CONDI-TIONS or o r conditions, are provided in the individual Surve111anc Require-sents. Surv 11ance Requirements for Special Test Exceptions need 1y be performed when he Special Test Exception is being utilized as an xception to an individual sp ification.

4.0.2 The pro fons of this specification provide all able tolerances for performing survei ance activities beyond those specif d in the nominal surveillance interval, hese tolerances are necessary t provide operational flexibility because of se duling and performance consi rations. Tha phrase "at least" associated with surveillance frequency d s not negate this allowable tolerance; instead, it permits the more f quent performance of surveillance activities.

The tolerance values, taken a her indivi ally or consecutively over three test intervals, are.sufficiently res ictive o ensure that the reliability associated with the surveillance activ ty not significantly degraded beyond II that obtained from the nominal speciffe nterval. '

4.D.3 The provisions of this sp ific ion set forth the criteria for determination of compliance with.th OPERABIL TY requirements of the Limiting Conditions for Operation. Under ese criteri equipment, systems or components are assumed to be OPERABLE if t associated sur 111ance activities have been satisfactorily performed withi the specified time nterval. Nothing in this provision is to be construed s defining equipment, stems or components OPERABLE, when such items e found or known to be in4 erable although still meeting the Surveillance equirements.

4.0.4 This spec ication ensures that survatilance ac vities associated with a Limiting Con tion for Operation have been performed thin the specifies time interval pri to entry into an applicable OPERATIONAL CO IT;0N or other specified appli 111ty condition. The intent of this provision s to ensure that surveill ce activities have been satisfactorily demonstrate n a current basis as re red to meet the OPERABILITY requirements of the Limit Condition for Operat n. i U er the terms of this specification, for example, during initial p nt l star or following extended plant outage, the applicable surveillance acJv-iti eust be performed within the stated surveillance intarval prior to pla ng o returning the system or equipment into OPERABLE status.

.0.5 This specification ensures that inservice inspection of ASME C Class 2 and 3 components and inservice testing of ASME Code Class 1, and 3 pumps an alves will be performed in accordance with a periodically dated version of tion XI of the ASME Boiler and Pressure Vessel Code Addenda, as required by CFR 50, Section 50.55a. Relief from any of above require-ments has been p ided in writing by the Comission and is n a part of these 1 Technical Specifica ns.

This specification ludes a clarification of frequencies of perform-ing the inservice inspectio nd testing activitie required by Section XI of cable Addenda. This clarifi-the ASME Boiler and Pressure el Code and ap cation is provided to ensure cons tency in veillance intervals throughout these Technical Specifications and remo any ambiguities relative to the ;

INSERT D l

Specifications 3.0.1 through 3.0.4 establish the general reouirements l applicable to Limiting Conditions for Operation. These requirements are based

, on the requirements for Limiting Conditions for Operation stated in the Code of Federal Regulations, 10CFR50.36(c)(2): ,

"Limiting conditions for operation are the lowest functional capability or i performance levels of equipment required for safe operation of the facility. ,

When a limiting condition for operation of a nuclear reactor is not met, the e licenste shall shut down the reactor or follow any remedial action permitted by the technical specification until the condition can be met."

]

l Specification 3.0.1 establishes the Applicability statement within each I individual specification as the requirement for when (i.e., in which OPERATIONAL CONDITIONS or other specified conditions) conformance to the Limiting Conditions for Operation is required for safe operation of the ,

, facility. The ACTION requirements establish those remedial measures that must l

be taken within specified time limits when the requirements of a Limiting !

Condition for Operation are not met. It is not intended that the shutdown i ACTION requirements be used as an operational convenience which permits i (routine) voluntary removal of a system (s) or component (s) from service in !

lieu of other alternatives that would not result in redundant systems or ,

components being inoperable. l

. t There are two basic types of ACTION requirements. The first specifies the remedial measures that permit continued operation of the facility which is not further restricted by the time limits of the ACTION requirements. In this '

] case, conformance to the ACTION requirements provides an acceptable level of l safety for unlimited continued operation as long as the ACTION requirements

~

4 continue to be met. The second type of ACTION requirement specifies a time I i

limit in which conformance to the conditions of the Limiting Condition for !

Operation must be met. This time limit is the allowable outage time to i I

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

the allowable outage time limits, a shutdown is required to place the facility l in an OPERATIONAL CONDITION or other specified condition in which the '

specification no longer applies, i

The specified time limits of the ACTION requirements are applicable from the 1

point ' t time it is identified that a Limiting Condition for Operation is not met. The time limits of the ACTION requirements are also applicable when a

, system or component is removed from service for surveillance testing or

investigation of operational problems. Individual specifications may include j a specified time limit for the completion of a Surveillance Requirement when

, equipment is removed from service. In this case, the allowable outage time J limits of the ACTION requirements are applicable when this limit expires if

{ the surveillance has not been complete 6 When a shutdown is required to

! comply with ACTION requirements, the plant m, uve entered an OPERATIONAL i CONDITION in which a new specification becon. plicable. In this case, the i time limits of the ACTION requirements would app./ from the point in time that l the new specification becomes applicable if the requirements of the Limiting Condition for Operation are not met.

Saecification 3.0.2 establishes that noncompliance with a specification exists w1en the requirements of the Limiting Condition for Operation are not met and the associated ACTION requirements have not been implemented within the specified time interval. The purpose of this specification is to clarify that (1) implementation of the ACTION requirements within the specified time interval constitutes compliance with a specification and (2) completion of the remedial measures of the ACTION requirements is not required when compliance with a Limiting Condition of Operation is restored within the time interval specified in the associated ACTION requirements.

Specification 3.0.3 establishes the shutdown ACTION requirements that must be implemented when a Limiting Condition for Operation is not met and the condition is not specifically addressed by the associated ACTION requirements.

The purpose of this specification is to delineate the time limits for placing the unit in a safe shutdown CONCITION when plant operation cannot be maintained within the limits for safe operation defined by the limiting Conditions for Operation and its ACTION requirements. It is not intended to be used as an operational convenience which permits (routine) voluntary removal of redundant systems or components from service in lieu of other alternatives that would not result in redundant systems or components being inoperable. One hour is allowed to prepare for an orderly shutdown before initiating a change in plant operation. This time permits the operator to coordinate the reduction in electrical generation with the load dispatcher to ensure the stability and availability of the electrical grid. The time limits specified to reach lower CONDITIONS of operation permit the shutdown to proceed in a controlled and orderly manner that is well within the specified maximum cooldown rate and within the cooldown capabilities of the facility assuming only the minimum required equipment is OPERABLE. This reduces themal stresses on components of the primary coolant system and the potential for a plant upset that could challenge safety systems under conditions for which this specification applies.

If remedial measures permitting limited continued operation of the facility under the provisions of the ACTION requirements are completed, the shutdown may be terminated. The time limits of the ACTION requirements are applicable from the point in time there was a failure to meet a limiting Condition for Opera tion. The re fore , the shutdown may be terminated if the ACTION requirements have been met or the time limits of the ACTION requirements have not expired, thus providing an allowance for the completion of the required actions.

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 COLD SHUTDOWN when a shutdown is required during POWER OPERATION. If the plant is in d lower CONDITION of operation when a shutdown is required, the time limit for reaching the next lower CONDITION of operation applies.

However, if a lower CONDITION of operation is reached in less time than allowed, the total allowable tine to reach COLD SHUTDOWN, or other OPERATIONAL CONDITION, is not reduced. For example, if STARTUP is reached in 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months , the 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 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 .

Therefore, if remedial measures are completed that would permit a return to POWER OPERATION, a penalty is not incurred by having to reach a lower CONDITION of operation in less than the total time allowed.

The same nrinciple 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 an OPERATIONAL CONDITION 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 CONDITION of operation may not be used to extend the allowable outage time tha t is applicable when a Limiting Condition for Operation is not met in a lower CONDITION of operation.

The shutdown requirements of Specification 3.0.3 do not apply in CONDITIONS 4 and 5, because the ACTION requirements of individual specifications def f ne the remedial measures to be taken.

Specification 3.0.4 establishes limitations on a change in OPERATIONAL CCNDIT:0NS when a Limiting Condition for Operation is not met. It precludes placing the facility in a higher CONDITION 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 teh ACTION requirements if a change in CONDITIONS were permitted. The purpose of this specification is to ensure that facility operation is not initiated or that higher CONDITIONS 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 spectiled limits. Compliance with ACTION requirements that permit continued operation of the facility for an unlimited period of time provides an acceptable level of safety for continued operation without regard to the status of the plant before or after a change in OPERATIONAL CONDITIONS. Therefore, in this case, entry into an OPERATIONAL ,

CONDITION or other specified condition may be made provided the ACTION requirements are being complied with exclusive of the allowable outage time limits. The provisions of this specification should not, however, be interpreted as endorsing the failure to exercise good practice in rettoring systems or components to OPERABLE status before plant startup.

When a shutdown is required to comply with ACTION requirements, the provisions of Specification 3.0.4 do not apply because they would delay placing the facility in a lower CONDITION of operation.

Specifications 4.0.1 through 4.0.5 establish the general requirements applicable to Surveillance Requirements. These requirements are based on the Surveillance Requirements stated in the Code of Federal Regulations, 10CFR50.36(c)(3):

"Surveillance requirements are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components 1 I

is maintained, that facility operation will be withir. safety limits, and that )

the limiting conditions of operation will be me+ " '

Specification 4.0.1 establishes the requirement that surveillances must be l pe rfo rved during the OPERATIONAL CONDIT!0h or other conditions for which the i

requirerents of the Limiting Conditio".s for Operation apply unless otherwise j stated in an individual Surveillance Requirement. The purpose of this Page 3 of 6 l

l l

specification is to ensure that surveillances are performed to verify the operational status of systems and components and that parameters are within specified limits to ensure safe operation of the facility when the plant is in an OPERATIONAL CONDITION or other specified condition for which the individual Limiting Conditions for Operation are applicable. Surveillance Requirements do not have to be performed when the facility is in an OPERATIONAL CONDITION for which the requirements of the associated Limiting Condition for Operation do not apply unless otherwise specified. The Surveillance Requirements associated with a Special Test Exception are only applicable when the Special Test Exception is used as an allowable exception to the requirements of a specification.

Specification 4.0.2 establishes the conditions under which the specified time interval for Surveillance Requirements may be extended. Item a. permitt an al?owable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not 60 suitable for conducting the surveillance; e.g., transient conditiont or other ongoing surveillance or maintenance activities. Item b.

limits the use of the provisions of item a. to ensure that it is not used repeatedly to extend the surveillance interval beyond that specified. The limits of Specification 4.0.2 are based on engineering judgment and the i

recognition that the most probable result of any particular surveillance being performed is the verification of confonnance with the Surveillance Requirements. These provisions are sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.

Specification 4.0.3 establishes the failure to perform a Surveillance I Requirement within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, as a condition that constitutes a failure tu meet the OPERABILITY requirements for a Limiting Condition for Operation.

Under the provisions of this specification, syscems and components are assumed to be OPERABLE when Surveillance Requirements have been satisfactorily performed within the specified time interval. However, nothing in this provision is to be construed as implying that systems or components are OPERABLE when they are found or known to be inoperable although still meeting the Surveillance Requirements. This specification also clarifies that the ACTION requirements are applicable when Surveillance Requirements have not been completed within the allowed surveillance interval and that the time ,

limits of the ACTION requirements apply from the point in time it is identified that a surveillance has not been performed and not at the time that '

the allowed surveillance interval was exceeded. Completion of the Surveillance Requirement within the allowable outage time limits of the ACTION requirements restores compliance with the requirements of Specification 4.0.3.

The failure to have performed the surveillance within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, constitutes a failure to reet the OPERABILITY requirements for a Limiting Condition for ,

Operation and any reports required by 10 CFR 50.73 shall be detennined based I on the length of time the surveillance interval has been exceeded, and the corresponding Limiting Conditions for Operation ACTION time requirements, as discussed in HUREG 1022. Supplement 1.

If the allowable outage time limits of the ACTION requirements are less than 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or a shutdown is required to comply with ACTION requirements, e.g.,

Specification 3.0.3., a 24-hour allowance is provided to pennit a delay in implementing the ACTION requirements. This provides an adequate time limit to complete Surveillance Requirements that have not been performed. The purpose of this allowance is to penni t the completion of a surveillance before a shutdown would be required to comply with ACTION requirements or before other remedial measures would be required that may preclude the completion of a surveillance. The basis for this allowance includes consideration for plant conditions, adequate planning, availability of personnel, the time required to perform the surveillance, and the safety significance of the delay in completing the required surveillance. This provision also provides a time limit for the completion of Surveillance Requirements that become applicable as a consequence of CONDITION changes imposed by ACTION requirements and for i completing Surveillance Requirements that are applicable when an exception to '

the requirements of Specification 4.0.4 is allowed. If a surveillance is not completed within the 24-hour alluwance, the time limits of the ACTION i requirements are applicable at that time. When a surveillance is performed within the 24-hour allowance and the Surveillance Requirements are not met, the time limits of the ACTION requirements are applicable at the time that the !

surveillance is terminated.

! Surveillance Requirements do not have to be performed on inoperable equipment l l

because the ACTION requirements define the remedial measures that apply, t

, However, the Surveillance Requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABLE status.

d Specification 4.0.4 establishes the requirement that all applicable surveillances must be met before entry into an OPERATIONAL CONDITION or other [

J condition of operation specified in the Applicability statement. The purpose of this specification is to ensure that system .ind component OPERABILITY requirements or parameter limits are met before entry into an OPERATIONAL CONDITION or other specified condition for which these systems and components !

ensure safe operation of the facility. This provision applies to changes in ;

OPERATIONAL CONDITIONS or other specified corditions associated with plant !

shutdowi, as well as startup.

l Under the provisions of this specification, the applicable Surveillance I l

Requirements must be performed within the specified surveillance interval to I

assume that the Limiting Conditions for Operation are met during initial plant i

, startup or following a plant cutage. '

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

! of Specification 4.0.4 do not apply because this would delay placing the i

facility in a lower CONDITION of operation.

I Specification 4.0.5 establishes the requirement that inservice inspection of l ASME Code Class 1, 2, and 3 components and inservice testing of ASME Code I Class 1, 2, and 3 pumps and valves shall be perfonned in accordance with a periodically updated version of Section XI of the ASME Boiler and Pre',sure Vessel Code and Addenda as required by 10C/R50.55a. These requirements spply

except when relief has been provided in writing by the Comission.

l This specification includes a clarification of the frequencies for perfonning the inservice inspection and testing activities required by Section XI of the l ASME Boiler and Pressure Vessel Code and applicable Addenda. This 1

clarification is provided to ensure consistency in surveillance intervals i throughout the Technical Specifications and to remove any ambiguities relative l to the frequencies for perfoming the required inservice inspection and '

testing activities.

Under the tems of this specification, the more restrictive requirements of l the Technical Specifications take precedence over the ASME Boiler and Pressure Vessel Code and applicable Addenda. The requirements of Specification 4.0.4 .

to perfom surveillance activities before entry into an OPERATIONAL CONDITION '

or other specified condition takes precedence over the ASVE Boiler and Pressure Vessel Code provision that allows pumps and valves to be tested up to one week after return to nortnal operation. The Technical Specification definition of OPERABLE does not allow a grace period before a component, which is not capable of performing its specified function, is declared inoperable i and takes precedence over the ASME Boilee and Pressure Vessel Code provision !

that allows a valve to be incapable of performing 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. '
