1.0 INTRODUCTION
This proposed License Amendment Request (LAR) is made pursuant to 10 CFR 50.90 to modify Technical Specifications (TS) requirements for surveillances in TS 4.0.a, TS requirements for missed surveillances in TS 4.0.c, and provide TS requirements for a Bases Control Program in TS 6.21.
2.0 DESCRIPTION
2.1 Consolidated Line Item Improvement The proposed changes to TS 4.0.c regarding missed surveillances, are consistent with Nuclear Regulatory Commission (NRC) approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specifications (STS) change TSTF-358 Revision 5, as modified by Federal Register Notice 66FR32400, of June 14, 2001, and in response to public comments. The availability of this TS improvement was published in the Federal Register on September 28, 2001, as part of the consolidated line item improvement process (CLIIP).
2.2 Additional Changes In addition to the above proposed changes to TS 4.0.c, TS 4.0.a will be revised to retain requirements that currently exist in TS 4.0.c. One requirement being moved from TS 4.0.c to TS 4.0.a establishes that failure to perform a surveillance requirement within the allowed interval, as defined by TS 4.0.b, constitutes a failure to meet the OPERABILITY requirements for a limiting condition for operation (LCO). The other requirement establishes that surveillance requirements do not have to be performed on inoperable equipment. This relocation of requirements from TS 4.0.c to TS 4.0.a does not result in a change to the requirements, and is being proposed to make the Kewaunee Nuclear Power Plant (KNPP) TS's more consistent with the STS. This will also enable the complete replacement .ofTS 4.0.c with the verbiage of STS SR 3.0.3.
Additionally, TS 4.0.a will be revised by adopting an STS requirement whereby failure to meet a surveillance, either during performance of the surveillance or between performances of the surveillances, shall be failure to meet the OPERABILITY requirements of the LCO. This change will provide clarification as to when surveillance requirements are required to be met, and the actions that are required when a surveillance requirement is known to not be met.
Docket 50-305 NRC-02-040 May 7, 2002 , Page 2 Because Kewaunee Nuclear Power Plant has Custom Technical Specifications (CTS) additional clarification must be added to the STS LCO wording. In KNPP CTS LCO is defined as including the OPERABILITY requirement, the conditions, the required action, and the associated Allowed Outage Time (AOT). In STS the LCO includes only the OPERABILITY requirements. To show this distinction between KNPP CTS and STS the term "LCO" is modified to show that it is only the OPERABILITY requirements of KNPP's CTS LCO is what is considered not being met.
Also, the term interval is being modified by adding the word surveillance to clarify that the interval of concern is the surveillance interval. This clarification is requested due to operator feedback questioning the term interval.
3.0 ASSESSMENT 3.1 Applicability of Published Safety Evaluation NMC has reviewed the safety evaluation dated June 8, 2001, as part of the CLIIP. This review included a review of the NRC staffs evaluation, as well as the supporting information provided to support TSTF-358. NMC has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to KNPP and justify this amendment for the incorporation of the changes to the KNPP TS.
3.2 Additional Changes KNPP TS 4.0.c differs from STS SR 3.0.3. KNPP TS 4.0.c states, "Failure to perform the surveillance requirement within the allowed surveillance interval, defined by TS 4.0.b. shall constitute noncompliance with the OPERABILITY requirements for a LIMITING CONDITION FOR OPERATION. The time limits of the action requirements are applicable at the time it is identified that a surveillance requirement has not been performed. The action requirements may be delayed for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to permit the completion of the surveillance when the allowable outage time limits of the action requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />." Therefore, the OPERABILITY requirement of the LCO is declared not met and the action requirements are applicable at the time of discovery for a missed surveillance. Additionally, although the action requirements may be delayed for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when the allowed outage time limits of the action requirements are less than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, no delay in the action requirements is provided when the allowable outage time limits of the action requirements are equal to or greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Docket 50-305 NRC-02-040 May 7, 2002 , Page 3 A proposed change to KNPP TS 4.0.a will require that failure to meet a surveillance, either during performance of the surveillance or between performances of the surveillances, shall be failure to meet the OPERABILITY requirement of the LCO.
This change clarifies that surveillances are required to be met at all times during the applicable MODES or specified conditions of the LCO. If it is known that a surveillance requirement cannot be met, the OPERABILITY requirement of the LCO shall be declared not met.
A proposed change to TS 4.0.c will allow equipment to be considered OPERABLE until a missed surveillance is performed (with risk management applied). However, the proposed change will not allow equipment known to be inoperable to be considered OPERABLE until the missed surveillance is performed. If it is known that the missed surveillance could not be met, TS 4.0.a will require the OPERABILITY requirement of the LCO to be declared not met. This change is acceptable, because the most likely outcome of any surveillance is verification that the OPERABILITY requirement of the LCO is met. Furthermore, failure to perform a surveillance within the allowed interval does not cause equipment to become inoperable.
Finally, TS 4.0.c is proposed to be changed such that the application of a delay period in which a missed surveillance is allowed to be performed is associated with the allowed surveillance interval, rather than the allowed outage time limit of the associated action. This change will also result in extending the application of a delay period for performing the missed surveillance to surveillances with associated actions that have allowed outage time limits greater than or equal to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Extending the performance of surveillances requires planning, personnel, preparation, and appropriate plant conditions. Some surveillances, when discovered missed, may require a change in the MODE of the facility to perform the surveillance. When faced with a missed surveillance that may require a change in MODE, operations personnel would have to either: 1) declare the OPERABILITY requirement of the LCO not met and enter the actions which could ultimately require a plant shutdown, 2) determine a method to perform the surveillance requirement in the current MODE, or 3) request a Notice of Enforcement Discretion - all potentially in the space of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. Adopting this change will reduce the need to apply for regulatory relief for the performance of these missed surveillances.

4.0 REGULATORY ANALYSIS
4.1 No Significant Hazards Determination NMC has reviewed the proposed no significant hazards consideration determination (NSHCD) published in the Federal Register as part of the CLIIP. NMC has concluded that the proposed NSHCD presented in the Federal Register notice is applicable to Kewaunee Nuclear Power Plant and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91(a).
4.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on September 28, 2001, for the missed surveillance TS improvement, plant-specific verifications were performed as follows:
NMC has established TS Bases for TS 4.0.c, which state that use of the delay period established by TS 4.0.c is a flexibility, which is not intended to be used as an operational convenience to extend surveillance intervals, but only for the performance of missed surveillances.
The modification will also include changes to the Bases for TS 4.0.c that provide details on how to implement the new requirements. The Bases changes provide guidance for surveillance intervals that are not based on time intervals but are based on specified unit conditions, OPERATING situations, or requirements of regulations. In addition, the Bases changes state that NMC is expected to perform a missed surveillance test at the first reasonable opportunity, taking into account appropriate considerations, such as the impact on plant risk and accident analysis assumptions, consideration of unit conditions, planning, availability of personnel, and the time required to perform the surveillance. The Bases also state that the risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risks Before Maintenance Activities at Nuclear Power Plants," and that the missed surveillance should be treated as an emergent condition, as discussed in Regulatory Guide 1.182. In addition, the Bases state that the degree of depth and rigor of the evaluation should be commensurate with the importance of the component and that missed surveillances for important components should be analyzed quantitatively. The Bases also state that the results of the risk evaluation determine the safest course of action. In addition, the Bases state that all missed surveillances will be placed in the licensee's Corrective Action Program. Finally, NMC has a Bases Control Program consistent with Section 5.5 of the STS.
Docket 50-305 NRC-02-040 May 7, 2002 , Page 5 5.0 ENVIRONMENTAL EVALUATION NMC has reviewed the environmental evaluation included in the model safety evaluation dated June 8, 2001, as part of the CLIIP. NMC has determined that the staff's findings presented in that evaluation are applicable to Kewaunee and the evaluation is hereby incorporated by reference for this application.
Additionally, with respect to the proposed changes to TS 4.0.a, TS 4.0.c and TS 6.21, the NMC has determined that the proposed amendment involves no significant hazards considerations and no significant change in the types of any effluents that may be released off-site and that there is no significant increase in the individual or cumulative occupational radiation exposure. Accordingly, this proposed amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with this proposed amendment.

4.0 SURVEILLANCE REQUIREMENTS APPLICABILITY
- a. Surveillance requirements shall be met during the operational MODES or other conditions specified for individual LIMITING CONDITIONS FOR OPERATION (LCO) unless otherwise stated in an individual surveillance requirement. Failure to meet a surveillance requirement, whether such failure is experienced during the performance of the surveillance or between performances of the surveillances, shall be failure to meet the OPERABILITY requirements for the LCO. Failure to perform a surveillance within the allowed surveillance interval, defined by TS 4.0.b, shall be a failure to meet the OPERABILITY requirements for the LCO except as provided in TS 4.0.c.
Surveillance requirements do not have to be performed on inoperable equipment.
- b. Each surveillance requirement shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25% of the specified surveillance interval.
- c. If it is discovered that a surveillance was not performed within its allowed surveillance interval, then compliance with the requirement to declare the OPERABILITY requirements for the LCO not met may be delayed from the time of discovery up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, or up to the limit of the allowed surveillance interval, whichever is greater.

Amcndmcnt Ne. 11!Proposed Amendment 180 TS 4.0-1 04A-W9505/7/2002
BASIS - Surveillance Requirements (TS 4.0)
TS 4.0.a establishes the requirements that surveillances must be performed during the operational MODES or other conditions for which the requirements of the LIMITING CONDITIONS FOR OPERATION (LCO) apply unless otherwise stated in an individual surveillance requirement. The purpose of this TS is to ensure that surveillances are performed to verify the operational status of systems and components and that parameters are within specified limits. This ensures safe operation of the facility when the plant is in a MODE or other specified condition for which the associated LCOs are applicable. Surveillance requirements do not have to be performed when the facility is in an operational MODE for which the requirements of the associated LCO do not apply unless otherwise specified. Surveillance requirements do not have to be performed on inoperable equipment because the action requirements define the remedial measures that apply. However, the surveillance requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABLE status.
TS 4.0.b establishes the limit for which the specified time interval for surveillance requirements may be extended. It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operation conditions that may not be suitable for conducting the surveillance (e.g., transient conditions or other ongoing surveillance or maintenance activities). It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18-month surveillance interval. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling outages. The limitation of TS 4.0.b is based on engineering judgement and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the surveillance requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.
TS 4.0.c establishes the flexibility to defer declaring affected equipment inoperable or an affected variable outside the specified limits when a surveillance has not been completed within the allowed surveillance interval. A delay period of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the allowed surveillance interval, whichever is greater, applies from the point in time that it is discovered that the surveillance has not been performed in accordance with TS 4.0.b, and not at the time that the allowed surveillance interval was not met.
This delay period provides adequate time to complete surveillances that have been missed. This delay period permits the completion of a surveillance before complying with required actions or other remedial measures that might preclude completion of the surveillance.
,Amcndmcnt No. 11 Proposed Amendment 180 TS B4.0-1 0Q1W9517/2002
The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the surveillance, the safety significance of the delay in completing the required surveillance, and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the requirements. When a surveillance with an allowed interval based not on time intervals, but upon specified unit conditions, OPERATING situations, or requiremen s of regulations (e.g., pnor to entering OPERATING MODE after each fuel loading, or in accordance with 10 CFR 50, Appendix J, as modified by approved exemptions, etc.T is discovered to not have been performed when specified, TS 4.0.c allows for the full delay period of up to the allowed surveillance interval to perform the surveillance. However, since there is not a time interval specified, the missed surveillance should be performed at the first reasonable opportunity.
TS 4.0.c provides a time limit for, and allowances for the performance of, surveillances that become applicable as a consequence of MODE changes imposed by required actions.
Failure to comply with allowed surveillance intervals for SRs is expected to be an infrequent occurrence. Use of the delay period established by TS 4.0.c is flexibility which is not intended to be used as an operational convenience to extend surveillance intervals.
While up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the limit of the allowed interval is provided to perform the missed surveillance, it is expected that the missed surveillance will be performed at the first reasonable opportunity. The determination of the first reasonable opportunity should include consideration of the impact on plant risk (from delaying the surveil ance as well as any plant configuration changes required or shutting the plant down to perform the surveillance) and impact on any analysis assumptions, in addition to unit conditions, planning, avai lability of personnel, and the time required to perform the surveillance. This risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants." This Regulatory Guide addresses consideration of temporary and aggregate risk impacts, determination of risk management action thresholds, and risk management action up to and including plant shutdown. The missed surveillance should be treated as an emergent condition as discussed in the Regulatory Guide. The risk evaluation may use quantitative, qualitative, or blended methods. The degree of depth and rigor of the evaluation should be commensurate with the importance of the component. Missed surveillances for important components should be analyzed quantitatively. If the results of the risk evaluation determine the risk increase is significant, this evaluation should be used to determine the safest course of action.
All missed surveillances will be placed in the licensee's Corrective Action Program.
If a surveillance is not completed within the allowed delay period, then the equipment is considered inoperable or the variable is considered outside the specified limits and the completion times of the required actions for the applicable LCO conditions begin immediately upon expiration of the delay period. If a surveillance is failed within the delay period, then the equipment is inoperable, or the variable is outside the specified limits and the completion times of the required actions for applicable LCO conditions begin immediately upon failure of the surveillance.
Amcndmcnt No. 11 WProposed Amendment 180 TS B4.0-2 04-1-89505/7/2002
Completion of the surveillance within the delay period allowed by this Specification, or within the completion time of the actions, restores compliance with TS 4.0.a.

This TS also clarifies that thc ACTION rcquircmcnts arc applicable whcn sur.'cillanee rcquremits have not bccn complcted within thc allowcd sur.eillanee interval. Thc time limits of thc- ACTION requirements apply fro)m thc timc it iidtfedthat a surweillanec has not bcc pc~frmcnd and not at the timc that thc allowcd suR'eillancc intcR'al was cxcecdcd.

If thc allowable outagc timc limits of thc ACTION rsquirments arc 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or a shutdown is rcquircd to comply with ACTION rcquircmcnts (c.g., TS9 3.0.c), a 21 hour2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> allowance is providcd.
This providcs, an adequate time limit to complete surveillance requirements that have not been pe~frmed. The purpose of this allowance is to pcFrmit the completion of a surveillance before -a shutdown is required to comply with ACTION requirements Or before othcr remedial mneasure would be required that mnay preclude completion of a surveillance. The basis for this allowance includes consideration for plant conditions, adequatc planning, availability of personnel and tim required to pefeffor the surveillance, and the safet significance of the delay in completingth required surveillance. This provision also provides a time limit for the completion of Sur.eillanc requremets that become applicable as a consequence of MOICDE changes imfposed by ACTION r-equiremnents and for comRplefing surveillance requirements that are applicable when an excseption to the rcquiremcnts of T-S 4.0.d is allowed. if a surveillance is not completed within the 21 hou allowance, the time limits of the ACTIOQN requiremcnts are applicable at that timc. When a surveillance is pertormned within the 21 hour2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br /> allowance and the surveillanc rqireents are not mnet, the time limits of the ACTION requiremnents are applicable at the time that the surveillance is te~nineted.
Surveillanc reurmnts do not have to be pertormed on inoperable equipment because the ACT-ION reureet define the remnedial mneasurcs that-apply. However, the surveillance requremets have to be mnet to demonstrate that inoperable equipment has been restored to O06PERABE status.
TS 4.O.d establishes the requirements that all applicable surveillance must be met before entry into an operational MODE or other condition of operation specified in the applicability statement.
The purpose of the TS is to ensure that system and component operability requirements or parameter limits are met before entry into a MODE or condition for which these systems and components ensure safe operation of the facility. This provision applies to changes in operational MODES or other specified conditions associated with plant shutdown as well as startup.
Amendment No. 11 @Proposed Amendment 180 TS B4.0-3 94914W9.505/7=20
Under the provisions of the TS, the applicable surveillance requirements must be performed within the specified surveillance interval to ensure that the LCOs are met during initial plant startup or following a plant outage.
When a shutdown is required to comply with AaGcltfiGoNn requirements, the provisions of TS 4.0.d do not apply because this would delay placing the racilrty in a lower MODE of operation.

4.0 SURVEILLANCE REQUIREMENTS APPLICABILITY
- a. Surveillance requirements shall be met during the operational MODES or other conditions specified for individual LIMITING CONDITIONS FOR OPERATION (LCO) unless otherwise stated in an individual surveillance requirement. Failure to meet a surveillance requirement, whether such failure is experienced during the performance of the surveillance or between performances of the surveillances, shall be failure to meet the OPERABILITY requirements for the LCO. Failure to perform a surveillance within the allowed surveillance interval, defined by TS 4.0.b, shall be a failure to meet the OPERABILITY requirements for the LCO except as provided in TS 4.0.c.
Surveillance requirements do not have to be performed on inoperable equipment.
- b. Each surveillance requirement shall be performed within the specified surveillance interval with a maximum allowable extension not to exceed 25% of the specified surveillance interval.
- c. If it is discovered that a surveillance was not performed within its allowed surveillance interval, then compliance with the requirement to declare the OPERABILITY requirements for the LCO not met may be delayed from the time of discovery up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, or up to the limit of the allowed surveillance interval, whichever is greater. This delay period is permitted to allow performance of the surveillance. A risk evaluation shall be performed for any surveillance delayed greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the risk impact shall be managed.
If the surveillance is not performed within the delay period, the OPERABILITY requirements for the LCO must immediately be declared not met, and the applicable conditions(s) must be entered.
When the surveillance is performed within the delay period and the surveillance is not met, the OPERABILITY requirements for the LCO must immediately be declared not met, and the applicable conditions(s) must be entered.
- d. Entry into an operational MODE or other specified condition shall not be made unless the surveillance requirement(s) associated with a LIMITING CONDITION FOR OPERATION have been performed within the stated surveillance interval or as otherwise specified. This provision shall not prevent passage through or to operational MODES as required to comply with action requirements.
Exceptions to these requirements are stated in the individual Technical Specifications.
TS4.0-1
BASIS - Surveillance Requirements (TS 4.0)
TS 4.0.a establishes the requirements that surveillances must be performed during the operational MODES or other conditions for which the requirements of the LIMITING CONDITIONS FOR OPERATION (LCO) apply unless otherwise stated in an individual surveillance requirement. The purpose of this TS is to ensure that surveillances are performed to verify the operational status of systems and components and that parameters are within specified limits. This ensures safe operation of the facility when the plant is in a MODE or other specified condition for which the associated LCOs are applicable. Surveillance requirements do not have to be performed when the facility is in an operational MODE for which the requirements of the associated LCO do not apply unless otherwise specified. Surveillance requirements do not have to be performed on inoperable equipment because the action requirements define the remedial measures that apply. However, the surveillance requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABLE status.
TS 4.0.b establishes the limit for which the specified time interval for surveillance requirements may be extended. It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operation conditions that may not be suitable for conducting the surveillance (e.g., transient conditions or other ongoing surveillance or maintenance activities). It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18-month surveillance interval. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling outages. The limitation of TS 4.0.b is based on engineering judgement and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the surveillance requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.
TS 4.0.c establishes the flexibility to defer declaring affected equipment inoperable or an affected variable outside the specified limits when a surveillance has not been completed within the allowed surveillance interval. A delay period of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the allowed surveillance interval, whichever is greater, applies from the point in time that it is discovered that the surveillance has not been performed in accordance with TS 4.0.b, and not at the time that the allowed surveillance interval was not met.
This delay period provides adequate time to complete surveillances that have been missed. This delay period permits the completion of a surveillance before complying with required actions or other remedial measures that might preclude completion of the surveillance.
TS B4.0-1
The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the surveillance, the safety significance of the delay in completing the required surveillance, and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the requirements. When a surveillance with an allowed interval based not on time intervals, but upon specified unit conditions, OPERATING situations, or requirements of regulations (e.g., prior to entering OPERATING MODE after each fuel loading, or in accordance with 10 CFR 50, Appendix J, as modified by approved exemptions, etc.) is discovered to not have been performed when specified, TS 4.0.c allows for the full delay period of up to the allowed surveillance interval to perform the surveillance. However, since there is not a time interval specified, the missed surveillance should be performed at the first reasonable opportunity.
TS 4.0.c provides a time limit for, and allowances for the performance of, surveillances that become applicable as a consequence of MODE changes imposed by required actions.
Failure to comply with allowed surveillance intervals for SRs is expected to be an infrequent occurrence. Use of the delay period established by TS 4.0.c is flexibility which is not intended to be used as an operational convenience to extend surveillance intervals.
While up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the limit of the allowed interval is provided to perform the missed surveillance, it is expected that the missed surveillance will be performed at the first reasonable opportunity. The determination of the first reasonable opportunity should include consideration of the impact on plant risk (from delaying the surveillance as well as any plant configuration changes required or shutting the plant down to perform the surveillance) and impact on any analysis assumptions, in addition to unit conditions, planning, availability of personnel, and the time required to perform the surveillance. This risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, "Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants." This Regulatory Guide addresses consideration of temporary and aggregate risk impacts, determination of risk management action thresholds, and risk management action up to and including plant shutdown. The missed surveillance should be treated as an emergent condition as discussed in the Regulatory Guide. The risk evaluation may use quantitative, qualitative, or blended methods. The degree of depth and rigor of the evaluation should be commensurate with the importance of the component. Missed surveillances for important components should be analyzed quantitatively. If the results of the risk evaluation determine the risk increase is significant, this evaluation should be used to determine the safest course of action.
All missed surveillances will be placed in the licensee's Corrective Action Program.
If a surveillance is not completed within the allowed delay period, then the equipment is considered inoperable or the variable is considered outside the specified limits and the completion times of the required actions for the applicable LCO conditions begin immediately upon expiration of the delay period. If a surveillance is failed within the delay period, then the equipment is inoperable, or the variable is outside the specified limits and the completion times of the required actions for applicable LCO conditions begin immediately upon failure of the surveillance.
TS B4.0-2
Completion of the surveillance within the delay period allowed by this Specification, or within the completion time of the actions, restores compliance with TS 4.0.a.
TS 4.0.d establishes the requirements that all applicable surveillance must be met before entry into an operational MODE or other condition of operation specified in the applicability statement.
The purpose of the TS is to ensure that system and component operability requirements or parameter limits are met before entry into a MODE or condition for which these systems and components ensure safe operation of the facility. This provision applies to changes in operational MODES or other specified conditions associated with plant shutdown as well as startup.
Under the provisions of the TS, the applicable surveillance requirements must be performed within the specified surveillance interval to ensure that the LCOs are met during initial plant startup or following a plant outage.
When a shutdown is required to comply with action requirements, the provisions of TS 4.0.d do not apply because this would delay placing the facility in a lower MODE of operation.
