3. 0.1 through 3. O. 4 generai-requfrements

----------/------applicable to Limiting Conditions for Operation.

These requirements are I based on the requirements for Limiting Conditions for Operation stated in I the Code of Federal Regulations, 10 CFR S0.36(c)(2):

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

When a limiting condition for operation of a nuclear reactor is I not met, the licensee shall shut down the reactor or follow any remedial I action permitted by the technical specifications until the condition can /. be met." I Specification 3.0.1 establishes the Applicability statement within each I individual specification as the requirement for when (i.e., in which */ plant condition or other specified conditions) conformance to the I Limiting Conditions for Operation is required for safe operation of the I facility.

The action requirements establish those remedial measures that I must be taken within specified time limits when the requirements of a I Limiting Condition for Operation are not met. I There are two basic types of action 'requirements.

The first specifies the I remedial measures that permit continued operation of the facility which is I not further restricted by the time limits of the action requirements.

In I this case, conformance to the action requirements provides an acceptable I level of safety for unlimited.continued operation as long as the action I requirements continue to be met. The se.cond type of action requirement

I specifies a time limit in which conformance to the conditions of the I Limiting Condition for Operation must be met. This time limit fs the I allowable outage time to restore an inoperable system or component to I OPERABLE status or for restoring parameters within specified limits. If / these actions are not completed within the allowable outage time limits, a I shutdown is required to place the facility in a plant condition in which I the specification no longer applies. 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 I in lieu of other alternatives that would not result in redundant systems I or components being inoperable.

I The specified time limits of the action requirements are applicable from I the point in time it is *identified that a Limiting Condition for Operation I is not met. The time limits of the action requirements are also applicable I when a system or component is removed from service for surveillance testing I or investigation of operational problems.

Individual specifications may I include a specified time limit for the completion of.a Surveillance I Requirement when equipment is removed from service. In this case, the I allowable outage time limits of the action requirements are applicable when I this time limit expires if the surveillance has not been completed.

When a I shutdown is required to comply with action requirements, the plant may have I entered a plant condition in which a new specification becomes applicable.

I .In this case, the time limits of the action requirements would apply from I .. the point :in time that the new specification becomes applicable if the requirements of the Limiting Condition for Operation are not met. I 3-la Amendment No. TSP0588-0025-NL02-NL04

I 'LIMITING CONDITIONS FOR OPERATION I -------------

*----Specification 3.0. 2 establishes that noncompliance with a specfficaifon

r-----

exists when the requirements of the Limiting Condition for Operation are I not met and the associated action requirements have not been implemented

/ within the specified time interval.

The purpose of this specification is I to clarify that (1) implementation of the action requirements within the I .to specified interval constitutes compliance with a specification and I (2) completion of the remedial measures of the action requirements is not I required when compliance with a Limiting Condition for Operation is restored I within the time interval specified in the associated action requirements.

I 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 pµrpose of this specification is to delineate the time limits for placing the unit in a safe shutdown condition when the 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 plant 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 thermal stress 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 Operation.

Therefore, 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 a lower operation condition when a shutdown is required,_

the time limit for reaching the next lower condition of operation applies. However, if a lower operating condition is reached in less time than allowed, the total allowable time to reach cold shutdown, or other 3-laa Amendment No. TSP0588-0025-NL02-NL04 I I I I I l I / I I I I I I I I I I I I I I I I I I I I I I I I I I I

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 plant operating condition in less than the total time allowed. The same principle applies with regard to the allowable outage time limits of the actio_n requirements, if compliance with the action requirements for one specification results in entry into a 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 reactor operating condition of operation may not be used to extend the ailowable outage time that is applicable when a Limiting Condition for Operation.

is not met in a lower plant condition of operation.

The shutdown requirements of Specification 3.0.3 do not apply during cold shutdown and refueling because the action requirements of individual specifications define the remedial measures to be taken. Specification 3.0.4 establishes limitations on reactor operating condition changes when a Limiting Condition for Operation is not met. It precludes placing the facility in a higher operational condition 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

the action requirements if a change in plant conditions were permitted.

The purpose of this specification is to ensure that facility operation is not initiated or that higher reactor operating conditions 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 acceptable level of safety for continued operation without regard to the status of the plant before or after a change in plant condition.

Therefore, in this case, entry into a reactor operating condition 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 action requirements, the provisions of Specification 3.0.4 do not apply because they would delay placing the facility in a lower plant condition of operation.

requirements I applicable to Surveillance Requirements.

These requirements-are--basea -on*-*---------;-------

the Surveillance requirements stated in the code of Federal Regulations, I 10 CFR 50.36(c)(3): . / "Surveillance requirements are requirements relating to test, calibration, or inspection to ensure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions of operation will be met." Specification

4. 0.1 establishes the requirement.

that surveillances must be performed during reactor operating conditions or other conditions for which the requirements of the Limiting Conditions for Operation apply, unless otherwise stated in an individual Surveillance Requirement.

The purpose of this 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 a reactor operating condition or other specified condition for which the associated 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 the the of a specification.*

Specification 4.0.2 establishes the conditions under which the specified time interval for Surveillance Requirements may be extended.

Item a. permits *an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be*suitable for conducting the surveillance; e.g., transient conditions 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 recognition that the most probable result of any particular surveillance being performed is the verification of conformance 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 Requirement within the allowed surveillance interval, defined by the provisions of Specification 4.0.2, as a condition that constitutes a failure to meet the operability requirements for a Limiting Condition for Operation.

Under the provisions of this specification, systems and components are assumed *to be operable when Surveillance Requirements have 4-lb Amendment No. TSP0588-0025-NL02-NL04 I I I I I I I I I I r I I I I I I I I I I I I I I I I I I I I I I I I I I I I I I

I nothing in this provision is to be construed as implying that systems or ------7-----

components are operable when they are found or known to be inoperable I although still_ meeting the Surveillance Requirements.

This specification I also clarifies that the action requirements are applicable when I Surveillance Requirements have not been completed within the allowed I surveillance interval and that the time limits of the action requirements I apply from the point in time it is.identified that a surveillance interval I was exceeded.

Completion of the Surveillance Requirement within the I allowable outage time limits of the action requirements restores compliance I with the requirements of 4.0.3. However, this does not I negate the fact that the failure to have performed the surveillance I within the allowed surveillance interval, defined by the provisions of I Specification 4.0.2, was a violation of the operability requirements of I a Limiting Condition for Operation that is subject to enforcement action. I Further, the failure to perform a surveillance within the provisions of I Specifications 4.0.2 is a violation of a Technical Specification I requirement and is, . therefore, a reportable event .under the requirements I of 10 CFR 50.73(a)(2)(i)(B) because it is a condition prohibited by the I plant's Technical Specifications.

I If the allowable outage time limits of the action requirements are less I 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, I e.g., Specification 3.0.3, a 24-hour allowance is provided to pennit a I delay in implementing action requirements.

This provides an adequate time *I limit to complete Surveillance Requirements that have not been performed.

I The purpose of this allowance

is* to p"ermit the completion of a surveillance I before a shutdown is required to comply with action requirements or before I other remedial would be required that may preclude completion of I a surveillance.

The basis for this allowance includes consideration for I plant conditions, adequate planning, availability of personnel, the time I required to perform the surveillance, and the safety significance of the I delay in completing the required surveillance.

This provision also I provides a time limit for the completion of Surveillance Requirements that I become applicable as a consequence of plant condition changes imposed by I action requirements and for completing Surveillance Requirements that are I applicable when an exception to the requirements of Specification 4.0.4 is I allowed. If a surveillance is not completed within the 24-hour allowance, I the time limits of the action requirements are applicable at that time. I When a surveillance is performed within the 24-hour allowance and the I Surveillance Requirements are not met, the time limits of the action I requirements are applicable at the time that the surveillance is I terminated.

I Surveillance Requirements do not have to be performed*on inoperable I equipment because the action requirements define the remedial measures I that apply. However, following expiration of the surveillance interval, I the Surveillance Requirements have to be met to demonstrate that I inoperable equipment has been restored to OPERABLE status.

r---------or other condition of operation specified in the Applicability statement.

I The purpose of this specification is to ensure that system and component I operability requirements or parameter limits are met before entry into an I operational condition for which these systems and components ensure safe I operation of the facility.

This provision applies to changes in reactor I operating conditions or other specified conditions associated with plant I shutdown as well as startup. I Under the provisions of this specification, the applicable Surveillance I Requirements must be perforined within the surveillance interval to ensure I that the Limiting Conditions for Operation are met during initial plant I startup or following a*plant outage. I When a shutdown is required to comply with action requirements, the I provisions of Specification 4.0.4 do not apply because this would delay I placing the facility in a lower operational condition.

I Specification 4.0.5 establishes the requirement that inservice inspection I of ASME Code Class 1, 2, and 3 components and inservice testing of ASME I Code Class 1, 2, and 3 pumps and valves shall be performed in accordance I with a periodically updated version of Section XI of the ASME Boiler and I __ Pressure Vessel Code and Addenda as required by 10 CFR 50.55a. These I requirements apply, except when relief has been provided in writing by I the Commission.

I This specification includes clarification of the frequencies for I performing the inservice inspection and testing activities required by I Section_ XI of the ASME Boiler and Pressure Vessel Code and applicabie I Addenda. This clarification is provided to ensure consistency in I surveillance intervals throughout the Technical Specifications and to I remove ambiguities relative to the frequencies for performing the I required inservice inspection and testing activities.

I Under the terms of this specification, the more restrictive requirements I of the Technical Specifications take precedence over the ASME Boiler and I Pressure Vessel Code and applicable Addenda. The requirements of I Specification 4.0.4 to perform surveillance activities before entry into I a reactor operating condition or other specified condition takes precedence I over the ASME Boiler and Pressure Vessel Code provision which allows pumps I and valves to be tested up to one week after return to normal operation.

I The Technical Specification definition operable does not allow a grace I period before a component, that is not capable of performing its specified I function, i-s declared inoperable and takes precedence over the ASME_Boiler

/ and Pressure Vessel Code provision which allows a valve to be incapable of I 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 I inoperable.

Whenever integrity of a pressure isolation valve listed in Table 4.3.1 cannot be demonstrated and credit is being taken for compliance with Specification 3.3.3.b, the integrity of the remaining check valve in each high pressure line having a leaking valve shall be determined and recorded daily and the position of the other closed valve located in that pressure line shall be recorded daily. j. Following each use of the LPSI system for shutdown cooling, the reactor shall not be made critical until the LPSI check valves (CK-3103, CK-3118, CK-3133*and CK-3148) have been verified closed. To satisfy ALARA requirements, leakage may be measured indirectly (as from the performance of pressure indicators) if supported by computations showing that the method is capable of demonstrating valve *compliance with-the leakage criteria *. (b)Reduced pressure testing is acceptable (see footnote 5 to Table 4.3.1). Minimum test differential pressure shall not be less than 150 psid. 4-17 TSP0588-0025-NL02-NL04 Amendment No 7t lJY, I I
