REFERENCES:
- 1. TSTF-358, Revision 5 as fully modified by Federal Register Notice 66FR32400, dated June 14, 2001

Dear Sir or Madam:
By letter (Reference 2), Entergy Operations, Inc. (Entergy) proposed a change to the Waterford Steam Electric Station, Unit 3 (Waterford 3) Technical Specifications (TSs) to incorporate TSTF-358 (Reference 1), Technical Specification Change Regarding Missed Surveillances Using the Consolidated Line Item Improvement Process.
The standard format of NUREG 1432, Rev. 2 Surveillance Requirement (SR) 3.0.1 is proposed for adoption into the Waterford 3 TS 4.0.1 equivalent. The purpose of this adoption is in support of an NRC request made in a telephone conversation on November 8, 2002.
Although the model application and NRC Safety Evaluation (SE) supporting approval of TSTF 358 did not require non-standard TS plants to adopt this change in conjunction with TSTF 358, the SE did contain the same clarifications found in the standard SR 3.0.1 wording.
Entergy agrees that adoption of SR 3.0.1 (Waterford 3 TS 4.0.1) would provide added clarification relevant to the application of SR 3.0.3 as modified by TSTF-358, and therefore, proposes to incorporate this change. Because the adoption of the standard wording of NUREG 1432, Rev. 2 into Waterford 3 TS 4.0.1 does not change current regulation or practice and the intent of the specification was discussed in the NRC approval of TSTF-358, the original No Significance Hazards Consideration (NSHC) is not impacted by this change.
The proposed change contains only minor variations or deviations from the wording of NUREG 1432, Rev. 2, in order to ensure clarity in light of the current (non-standard)
Waterford 3 TS format. The font and other page formatting options are converted to mimic the standard format as closely as possible. The variations are limited to the following:
Coo
W3FI-2002-0102 Page 2 of 3 December 19, 2002
" The acronym "SR" used in standard SR 3.0.1 and SR 3.0.1 Bases is replaced with
"=Surveillane" or 'Surveillance Requirement" as appropriate in the Waterford 3 TSs and Bases. This is an administrative change only to support Waterford 3 TS accepted wording.
" The term "Frequency" in standard SR 3.0.1 and SR 3.0.1 Bases is changed to "interval" to be consistent with the Waterford 3 TSs and Bases. This is an administrative change only and does not change the meaning or intent of the specification.
"* Reference to SR 3.0.2 or SR 3.0.3 in the standard SR 3.0.1 or SR 3.0.1 Bases is changed to the Waterford 3 equivalent of 4.0.2 or 4.0.3, respectively. This is an administrative change only.
" The phrase "Required Actions" or "ACTIONS" found in the standard SR 3.0.1 Bases is replaced with the phrase "LCO Action Statements" or "Action Statements" in the Waterford 3 TS 4.0.1 Bases to be consistent with Waterford 3 TS terminology. This is an administrative change only.
" Reference to an "Auxiliary" feedwater pump and the acronym "AFW" in the standard SR 3.0.1 Bases is replaced with Waterford 3 system terminology of "Emergency" feedwater pump and the corresponding acronym *EFW." This is an administrative change only.
" The example of testing an AFW pump at steam generator pressure of > 800 psi in the standard SR 3.0.1 Bases is changed to > 750 psig in the Waterford 3 4.0.1 Bases to be consistent with Waterford 3 EFW Surveillance Requirement 4.7.1.2b. This is an administrative change only and does not change the intent of the respective Bases.
The last sentence of the current TS 4.0.3 is also deleted because it is redundant to a sentence added to TS 4.0.1 during the above incorporation of standard TS wording.
Additionally, the addition of the revised 4.0.1 wording necessitated that the portion of 4.0.5 on page 3/4 0-2 be moved to the top of page 3/4 0-3. Markups of the affected TS pages are included in Attachment I and revised TS pages are included in Attachment 2. Markups of the affected TS Bases pages are provided in Attachment 3 for information only.
During the November 8, 2002 call, the NRC noted that Entergy had not included a Bases Control Program in the submittal (Reference 2) for Waterford 3. A Bases Control Program was not included in the submittal because Entergy previously implemented a Bases Control Program, consistent with NUREG 1432, at Waterford 3 in Amendment 161. The NRC approved Amendment 161 on May 9, 2000.
Finally, the original submittal (Reference 2) contained a commitment that read, "The modification will also include changes to the Bases for Specification 4.0.3 that provide details on how to implement the new requirements. This commitment is being revised to read, "The modification will also include changes to the Bases for Specifications 4.0.1 and 4.0.3 that provide details on how to implement the new requirements." This revised commitment is identified in Attachment 4.

Soecification4.0.2 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 operating conditions that may not be suitable for conducting the surveillance; e.g., transient conditions or other ongoing surveillance or maintenance actvities. It also provides f*xibility 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 Specification 4.0.2 Is 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. 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.
This extension allowed by Specification 4.0.2 Is also applicable to Surveillance Requirements required in Technical specification Actions. However, the extension does not apply to the initial performance. The extension only applies to each performance after the Initial performance.
The Initial performance required by the Action, whether it is a particular Surveillance or some other remedial action, is considered a single action with a single completion time. One reason for not allowing the extension to this completion time is that such an action usually verifies that no loss of function has occurred or accomplishes the function of the inoperable equipment in an alternative manner.

Page 3 of 6 Surveillance Requirements do not have to be performed on inoperable equvpment because the ACTION requirements define the remedial measures -hat apply. However, the Surveillance Requirements have to be met to demonstrate that inoperable equipment has been restored to OPERABL status.
SDetiflcatlon 4.0.4 establishes the requirement that all applicable surveillance must be met before entry into an OPERATIONAL NWDE or other condition of operation specified in the Applicabflity statement. The purpose of this specification is to ensure that system and comonent OPERABILITY requirements or parameter linits are met before entry into a NODE or condition for which these systems and components ensure safe operation of the facility.
This provision applies to changes in OPERATIONAL HOOES or other specified conditions associated witt, plant shutdown as well as startup.
Under the provisions of this specification, the applicable Surveillance Requirements must be performed within the specified surveillance interval to ensure that the Limiting Condition for Operation are met daring Initial plant startup or following a plant outage.
.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 facility in a lower NODE of operation.
Sipefictation 4.O.1 establishes the requirement that inservice inspection of ASME Code Class I1, 2, and 3 components and Inservice testing of AS*E Code Class 1) 2 and 3 pumps and valves shall be performed In accordance with a periodically updated version of Section X1 of the ASME Boiler and Pressure Vessel Code and Addenda as required by 10 CFR 50.SSa. These requirements apply except when, relief has been provided in writing by the Commission.
This specification includes a clarification of the frequencies for performing the inservice inspection and testing activities required by Section XI of the ASHE Boiler and Pressure Vessel Code and applicable Addenda.
This clarification Is provided to ensure consistency In surveillance intervals throughout these Technical Specifications and to renove any ambiguities relative to the frequencies for performing the required Itnservice Inspection and testing activities.
Under the terms of this specification, the aore restrictive requirements of the Technical Specifications take precedence over the ASHE Boiler and Pressure Vessel Code and applicable Addenda. For examle, the requirements of Specification 4.0.4 to perform survetllance activities pr1or to entry into an OPERATIONAL WE or other specified applicability condition takes precedence over the ASHE Boiler and Pressure Vessel Code provision which allows pumps to be tested up to one week after return to norsea operation. And for example, the Technical Specification definition of OPERABLE does not grant a grace period before a device that Is not capable of performing Its specified function is declared inoperable and takes Orecedence over the ASME Boiler and Pressure Vessel Code provision which allows a valve to be incapable of performing Its specified function for up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before being declared inoperable.
WATERFORD - UNIT 3 B3406AEDETN.9 6 3/4 0-6 AMENDMENT NO. 99 to W3F1-2002-0102 4.
Page 4 of 6 BASES INSERT 4.0.1 Specification 4.0.1 establishes the requirement that Surveillances must be performed during the MODES or othri specified conditions in the Applidability for which the requirements of the LCO apply, unless otherwise specified in the individual Surveillance Requirements. This specification is to ensure that Surveillances are performed to verify the OPERABILITY of systems and components, and that variables are within specified limits.
Failure to meet a Surveillance within the specified interval, in accordance with 4.0.2, constitutes a failure to meet an LCO.
Systems and components are assumed to be OPERABLE when the associated Surveillance Requirements have been met. Nothing in this Specification, however, is to be construed as implying that systems or components are OPERABLE when either:
- a. The systems or components are known to be inoperable, although still meeting the Surveillance Requirements or
- b. The requirements of the Surveillance(s) are known to be not met between required Surveillance performances.
Surveillances do not have to be performed when the unit is in a MODE or other specified condition for which the requirements of the associated LCO are not applicable, unless otherwise specified. The Surveillance Requirements associated with a special test exception (STE) are only applicable when the STE is used as an allowable exception to the requirements of a Specification.
Unplanned events may satisfy the requirements (including applicable acceptance criteria) for a given Surveillance. In this case, the unplanned event may be credited as fulfilling the performance of the Surveillance. This allowance includes those Surveillances whose performance is normally precluded in a given MODE or other specified condition..
Surveillances, including Surveillances invoked by LCO Action Statements do not have to be performed on inoperable equipment because the Action Statements define the remedial measures that apply. Surveillances have to be met and performed in accordance with 4.0.2, prior to returning equipment to OPERABLE status.
Upon completion of maintenance, appropriate post maintenance testing is required to declare equipment OPERABLE. This includes ensuring applicable Surveillances are not failed and their most recent performance is in accordance with 4.0.2. Post maintenance testing may not be possible in the current MODE or other specified conditions in the Applicability due to the necessary unit parameters not having been established. In these situations, the equipment may be considered OPERABLE provided testing has been satisfactorily completed to the extent possible and the equipment is not otherwise believed to be incapable of performing its function. This will allow operation to proceed to a MODE or other specified condition where other necessary post maintenance tests can be completed.
Some examples of this process are:
- a. Emergency feedwater (EFW) pump turbine maintenance during refueling that requires testing at steam pressures > 750 psig. However, if other appropriate testing is satisfactorily completed, the EFW System can be considered OPERABLE. This allows to W3FI-2002-0102 Page 5 of 6 startup and other necessary testing to proceed until the plant reaches the steam pressure required to perform the testing.
- b. High pressure safety injection (HPSI) maintenance during shutdown that requires system functional tests at a specified pressure. Provided other appropriate testing is satisfactorily completed, startup can proceed with HPSI considered OPERABLE. This allows operation to reach the specified pressure to complete the necessary post maintenance testing.
BASES INSERT 4.0.3 Specification 4.0.3 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 its specified 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 specified 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 Specification 4.0.2, and not at the time that the specified interval was not met.
This delay period provides an 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.
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 interval based not on time intervals, but upon specified unit conditions, operational situations, or requirements of regulations (e.g., prior to entering MODE I 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, Specification 4.0.3 allows for the full delay period of up to the specified 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.
Specification 4.0.3 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 specified intervals for surveillance requirements is expected to be an infrequent occurrence. Use of the delay period established by Specification 4.0.3 is a 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 specified 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 to W3FI-2002-0102 Page 6 of 6 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 allowed outage times of the required actions for the applicable LCO 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 allowed outage times of the required actions for the applicable LCO begin immediately upon the failure of the Surveillance.
Satisfactory completion of the Surveillance within the delay period allowed by this Specification, or within the allowed outage time of the actions, restores compliance with Specification 4.0.1.
