1.0 DESCRIPTION

The proposed amendment would modify Waterford Steam Electric Station, Unit 3 (Waterford 3)

Technical Specification (TS) requirements for inoperable snubbers by relocating the current TS 3.7.8, Snubbers, to the Technical Requirements Manual (TRM) and adding Limiting Condition for Operation (LCO) 3.0.8. In conjunction with the proposed changes, TS Bases for LCO 3.0.8 will be added, consistent with the Bases Control Program as described in Section 6.16 of the TS.

The changes relating to the addition of LCO 3.0.8 are consistent with the Nuclear Regulatory Commission (NRC) approved Industry / Technical Specification Task Forceý (TSTF) change to the Improved Standard Technical Specifications TSTF-372-A, Rev. 4, entitled Addition of LCO 3.0.8, Inoperability of Snubbers. The availability of this TS improvement was published in the Federal Register on April 27, 2005 as part of the consolidated line item improvement process (CLIIP). The change which relocates TS 3.7.8 to the TRM is consistent with the Improved Standard Technical Specification (STS), which does not contain a specification for snubbers.

2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation With regard to application-of TSTF -372 (adoption of LCO 3.0.8), Entergy Operations, Inc.

(Entergy) has reviewed the safety evaluation dated April 27, 2005 as part of the CLIIP. This review included a review of the NRC staff's evaluation, as well as the information provided to support TSTF-372. Entergy has concluded that the justifications presented in the TSTF proposal and the safety evaluation prepared by the NRC staff are applicable to Waterford 3 and justify this amendment for the incorporation of the changes to the Waterford 3 TS.

The relocation of the snubber-related requirements of TS 3.7.8 to the TRM is consistent with the original (and current) version of the STS. The NRC's Final Policy Statement states that LCOs and associated requirements that do not satisfy or fall within any of the four specified criteria presently contained in 10 CFR 50.36, maybe relocated from existing TS (an NRC-controlled document) to appropriate licensee-controlled documents. Relocation of these requirements to the TRM is acceptable, in that, changes to the TRM will be adequately controlled by 10 CFR 50.59. These provisions will continue to be implemented by appropriate station procedures (i.e., operating procedures, maintenance procedures, surveillance and testing procedures, and work control procedures).

Snubbers are used on piping systems or equipment to limit displacement from dynamic loads such as earthquake or thermal-hydraulic transient, while allowing displacement from thermal expansion. Snubbers are not active components, but are a type of support like springs, baseplates, or struts with the same potential for impact on operability as any support. The majority of snubbers at Waterford 3 are installed on Seismic Class I piping, which include all of the safety systems. Snubber testing is required by 10 CFR 50.55a to be performed in accordance with ASME/American Nuclear Standards Institute (ANSI) OM Part 4, "Examination and Performance Testing of Nuclear Power Plant Dynamic Restraints" or ASME OM Code, Subsection ISTD, "Preservice and Inservice Examination and Testing of Dynamic Restraints (Snubbers) in Light-Water Reactor Nuclear Power Plants." Thus, specifying such testing in the to W3F1 -2008-0059 Page 2 of 5 TS is unnecessary. Snubbers are not a design feature that is an initial condition of a DBA or transient. Thus, TS requirements forsnubbers do not meet the criteria of 10 CFR 50.36 for retention in the TS. In addition, snubber degradation does not necessarily render the associated safety system inoperable. Rather, it is appropriate to evaluate issues with a snubber using existing guidance for degraded or nonconforming conditions within the corrective action program. If a problem with one or more snubbers did make a system or component, inoperable, the TS for the affected system will define the appropriate remedial actions. Testing will be adequately controlled in accordance with 10 CFR 50.55a and 10 CFR 50.59. Based on the above, it is acceptable to relocate the snubber specification to the TRM.

2.2 Optional Changes and Variations The relocation of TS 3.7.8 to the TRM is not included in the CLiUP associated with TSTF-372.

However, this relocation is necessary to support application of the new LCO 3.0.8 and the intent of TSTF-372. Furthermore, this relocation is consistent with the STS.

Because Waterford 3 is a non-STS plant and because Entergy proposes to relocate TS 3.7.8 to support the adoption of LCO 3.0.8, these changes are not proposed to be approved under the normal 6-month CLIIP review process. Notwithstanding the additional review and time the NRC may require to issue the requested amendment, Entergy has confirmed that all other requirements of the CLIIP, as stated in Section 2.1 above, are met for Waterford 3. Given the necessity of TS 3.7.8 relocation in order to adopt TSTF-372, Entergy believes this deviation is minor.

Other than discussed above, the only remaining minor deviation is the maintenance of Waterford 3 custom TS wording and usage rules in the adoption of TSTF-372. Specifically:

1. TSTF-372 adds LCO 3.0.8 reference to LCO 3.0.1. Currently, the STS has reference to LCO 3.0.2 and 3.0.7 within LCO 3.0.1. Waterford 3 TS does not contain LCO 3.0.7 (associated with Special Test Exceptions); therefore, reference to LCO 3.0.7 is not included in the Waterford 3 LCO 3.0.1. However, reference to LCO 3.0.2 should be included and, therefore, Entergy is adding this reference to the Waterford 3 LCO 3.0.1 to gain consistency with the STS.
2. As discussed in Item 1 above, Waterford 3 does not have an LCO 3.0.7. However, to maintain consistent numbering (where possible) with the STS, Waterford 3 proposes to add an LCO 3.0.6 and LCO 3.0.7 placeholder which will permit using the LCO 3.0.8 designation for snubbers, consistent with TSTF-372 and the STS.
3. Item 1(e) of the model Safety Evaluation (SE), Section 3.2, contains the statement "LCO 3.0.8 does not apply to non-seismic snubbers." This does not appear to be captured in the implementation process of the TSTF. Therefore, Entergy proposes to include this statement in the LCO 3.0.8 Bases (see Attachment 5 of this submittal). Further guidance associated with the intent of this statement, as discussed in Section 3.0 of the model SE and in TSTF-IG-05-03, Implementation Guidance for TSTF-372, Revision 4, "Addition of LCO 3.0.8, Inoperability of Snubbers," is also included in the Bases. In addition, the TSTF use of "10 CFR 50.36(c)(2)(ii)" is modified to simply state 10 CFR 50.36. This is due to the recent rule change that inadvertently re-designated Part 50.36(c) as Part 50.36(d).

to W3F1 -2008-0059 Page 3 of 5

4. The footer of TS Page 3/4 7-20 is revised to account for the pages being deleted by the relocation of TS 3.7.8. This is administrative in nature.

These variations are few and insignificant with regard to ensuring proper application of TSTF-372 intent. Note that TS Page 3/4 7-20 is tied to the August 16, 2007 Entergy letter to adopt TSTF-448, which is currently under review by the NRC. The proposed changes contained within the TSTF-448 submittal are not shown on the attached mark-up or clean page for TS Page 3/4 7-20.

3.0 REGULATORY ANALYSIS

3.1 No Significant Hazards Consideration Determination Entergy Operations, Inc. (Entergy) has reviewed the proposed no significant hazards consideration determination (NSHCD) published in the FederalRegister as part of the CLIIP.

Entergy has concluded that the proposed NSHCD presented in the FederalRegister notice is applicable to Waterford 3 and is hereby incorporated by reference to satisfy the requirements of 10 CFR 50.91 (a).

3.2 Verification and Commitments As discussed in the notice of availability published in the Federal Register on April 27, 2005 for this TS improvement, plant-specific verifications were performed as follows:

In the model Safety Evaluation (SE), two Conditions [the first of the two having five parts, 1(a) through 1(e)] for application of TSTF-372 are specified. Each is discussed below.

Condition 1 Appropriate plant procedures and administrative controls will be used to implement the following Tier 2 restrictions. Tier 2 restrictions (Conditions) involve the identification of potentially high-risk configurations that could exist if equipment in addition to that associated with the change were to be taken out of service simultaneously, or other risk significant operational factors such as concurrent equipment testing were also involved.

1. Condition 1(a) assumes the availability of one Emergency Feedwater (EFW) train during application of LCO 3.0.8.a. The TSTF-372 and the model SE specify the application of LCO 3.0&8.a is contingent on the assumption that the redundant train remains available.

Even though Waterford 3 has a unique EFW system design, the plant TS LCO and ACTION statements will ensure the system remains capable of performing its safety function with various combinations of pumps and flow paths OPERABLE. Although the TS implementation process at Waterford 3 may include this restriction in other procedures or administrative processes upon approval of this amendment, Entergy does not believe further action is required to ensure compliance with Condition 1(a) since the TS inherently prevents application of LCO 3.0.8.a due to a snubber-related condition which could render the entire EFW system inoperable.

2. Condition 1(b) requires either one EFW train or some alternative means of core cooling must be available when one or more snubbers are inoperable that affect both trains of a to W3F1 -2008-0059 Page 4 of 5 given system. As described in Condition 1(a) above, there are no instances where the EFW system or both trains of any system being relied upon as the only core cooling method would be removed from service or any work permitting both at the same time during its associated Modes of Applicability that require these systems. Again, such a plant configuration would result in LCO 3.0.3 entry or plant shutdown, which prevents the utilization of the 12-hour allowance of LCO 3.0.8.b. Although the TS implementation process at Waterford 3 may include this restriction in other procedure or administrative processes upon approval of this.amendment, Entergy believes the TS LCO and ACTION statements will ensure the system remains capable of performing its safety function with no further action required to ensure compliance with Condition 1 (b).
3. Conditions 1(c) and 1(d) are only applicable to west coast plants and boiling water reactors, respectively, and therefore, are not applicable to Waterford 3.
4. Condition 1(e), first part, relates to Conditions 1(a) and 1(b) discussed above. The statement "LCO 3.0.8 does not apply to non-seismic snubbers" is added to the TS Bases (see markup in Attachment 5 of this submittal). This is a minor deviation from TSTF-372 and is discussed in Section 2.2 aboye. The second part of Condition 1(e) requires that the design function of the inoperable snubber (i.e., seismic vs. non-seismic), implementation of any Tier 2 restrictions during the use of LCO 3.0.8, and the associated plant configuration are recoverable (e.g. can be produced) for staff inspection. Entergy will ensure, during the relocation of the TS 3.7.8 snubber requirements to the TRM, that the TRM Actions are modified, in accordance with 10 CFR 50.59, to require a record of the design function of the inoperable snubber (i.e.,

seismic vs. non-seismic), implementation of any Tier 2 restrictions each time a required snubber is rendered inoperable and the associated plant configuration are available for NRC staff inspection. This commitment is included in Attachment 4 of this submittal.

Condition 2 Implementation of the provisions of LCO 3.0.8 must be performed in accordance with an overall Continuous Risk Management Program (CRMP). Waterford 3 has and continues to maintain a CRMP and associated risk-related tools to meet the intent of 10 CFR 50.65(a)(4) of the Maintenance Rule. Entergy will revise plant procedures or administrative process to ensure seismic risks are considered in conjunction with other plant maintenance activities and integrated into the existing 10 CFR 50.65(a)(4) process during application of the LCO 3.0.8 delay period when one or more snubbers are inoperable. This commitment is included in Attachment 4 of this submittal.

In addition to the above Conditions, Entergy will establish TS Bases for'LCO 3.0.8 which provide guidance and details on how to implement the new requirements. This commitment is included in Attachment 4 of this submittal. LCO 3.0.8 requires that risk be managed and assessed. The Bases also state that while the Industry and NRC guidance on implementation of 10 CFR 50.65(a)(4) (the Maintenance Rule) does not address seismic risk, LCO 3.0.8 should be considered with respect to other plant maintenance activities, and integrated into the existing Maintenance Rule process to the extent possible so that maintenance on any unaffected train or subsystem is properly controlled, and emergent issues are properly addressed. The risk assessment need not be quantified, but may be a qualitative assessment of the vulnerability of systems and components when one or more snubbers are not able to perform their associated to W3F1 -2008-0059 Page 5 of 5 support function. Finally, Waterford 3 has a Bases Control Program consistent with Section 5.5 of the STS and is contained in Waterford 3 TS Section 6.16.

4.0 ENVIRONMENTAL EVALUATION Entergy has reviewed the environmental evaluation included in the model safety evaluation dated April 27, 2005 as part of the CLIIP. Entergy has concluded that the staff's findings presented in that evaluation are applicable to Waterford 3, and the evaluation is hereby incorporated, by reference for this application.

Attachment 5 To W3F1-2008-0059 Proposed Technical Specification Bases Changes (for information only) to W3F1 -2008-0059 Page 1 of 3 BASES 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 MODE of operation.

Specification 3.0.5 establishes the allowance for restoring equipment to service Under administrative controls when it has been removed from service or declared inoperable to comply with ACTIONS. The sole purpose of this Specification is to provide an exception to Specification 3.0.2 (e.g., to not comply with the applicable Required Action(s)) to allow the performance of Surveillance Requirements to demonstrate:

a. The OPERABILITY of the equipment being returned to service; or
b. The OPERABILITY of other equipment.

The administrative controls ensure the time the equipment is returned to service in conflict with the requirements of the ACTIONS is limited to the time absolutely necessary to perform the allowed Surveillance Requirements. This Specification does not provide time to perform any other preventive or corrective maintenance.

An example of demonstrating the OPERABILITY of the equipment being returned to service is reopening a containment isolation valve that has been closed to comply with Required Actions and must be reopened to perform the Surveillance Requirements.

An example of demonstrating the OPERABILITY of other equipment is taking an inoperable channel or trip system out of the tripped condition to prevent the trip function from occurring during the performance of a Surveillance Requirement on another channel in the other trip system. A similar example of demonstrating the OPERABILITY of other equipment is taking an inoperable channel or trip system out of the tripped condition to permit the logic to function and indicate the appropriate response during the performance of a Surveillance Requirement on another channel in the same trip system.

Specification 3.0.8 LCO 3.0.8 establishes conditions under which systems are considered to remain capable of performing their intended safety function when associated snubbers are not capable of providing their associated support function(s). This LCO states that the supported system is not considered to be inoperable solely due to one or more snubbers not capable of performing their associated support function(s). This is appropriate because a limited length of time is allowed for maintenance, testing, or repair of one or more snubbers not capable of performing their associated support function(s) and appropriate compensatory measures are specified in the snubber requirements, which are located outside of the Technical Specifications (TS) under licensee control. The snubber requirements do not meet the criteria in 10 CFR 50.36, and, as such, are appropriate for control by the licensee.

If theI allowed time expires and the snubber(s) are unable to perform their associated support function(s), the affected supported system's LCO(s) must be declared not met and the ACTIONS entered in accordance with LCO 3.0.2.

WATERFORD - UNIT 3 B 3/4 0-4 AMENDMENT NO. 62,,-1-04 Changed by letter dated August-22,4QQ0 CHANGE NO. 3G, to W3F1 -2008-0059 Page 2 of 3 BASES LCO 3.0.8.a applies when one or more snubbers are not capable of providing their associated support function(s) to a single train or subsystem of a multiple train or subsystem supported system or to a single train or subsystem supported system. LCO 3.0.8.a allows 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to restore the snubber(s) before declaring the supported system inoperable. The 72-hour allowed outage time (AOT) is reasonable based on the low probability of a seismic event concurrent with an event that would require operation of the supported system occurring while the snubber(s) are not capable of performing their associated support function and due to the availability of the redundant train of the supported system.

LCO 3.0.8.b applies when one or more snubbers are not capable of providing their associated support function(s) to more than one train or subsystem of a multiple train or subsystem supported system. LCO 3.0.8.b allows 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to restore the snubber(s) before declaring the supported system inoperable. The 12-hour AOT is reasonable based on the low probability of a seismic event concurrent with an event that would require operation of the supported system occurring while the snubber(s) are not capable of performing their associated support function.

LCO 3.0.8 requires that risk be assessed and managed. Industry and NRC guidance on the implementation of 10 CFR 50.65(a)(4) (the Maintenance Rule) does not address seismic risk. However, use of LCO 3.0.8 should be considered with respect to other plant maintenance activities, and integrated into the existing Maintenance Rule process to the extent possible so that maintenance on any unaffected train or subsystem is properly controlled, and emergent issues are properly addressed. The risk assessment need not be quantified, but may be a qualitative awareness of the vulnerability of systems and components when one or more.

snubbers are not able to perform their associated support function.

LCO 3.0.8 does not apply to non-seismic snubbers. The provisions of LCO 3.0.8 are not to be applied to supported TS systems unless the supported systems would remain capable of performing their required safety or support functions for postulated design loads other than seismic loads.

The risk impact of dynamic loadings other than seismic loads was not assessed as part of the development of LCO 3.0.8. These shock-type loads include thrust loads, blowdown loads, water-hammer loads, steam-hammer loads, LOCA loads and pipe rupture loads.

However, there are some important distinctions between non-seismic (shock-type) loads and seismic loads which indicate that, in general, the risk impact of the out-of-service snubbers is smaller for non-seismic loads than for seismic loads. First, while a seismic load affects the entire plant, the impact of a non-seismic load is localized to a certain system or area of the plant. Second, although non-seismic shock loads may be higher in total force and the impact could be as much or more than seismic loads, generally they are of much shorter duration than seismic loads. Third, the impact of non-seismic loads is more plant specific, and thus harder to analyze generically, than for seismic loads. For these reasons, every time LCO 3.0.8 is applied, at least one train (or subsystem) of each system that is supported by the inoperable snubber(s) should remain capable of performing their required safety or support functions for postulated design loads other than seismic loads.
