-UNIT 3/43-18b AMENDMENT NO. 47, 143, 154, 225 UNITED NUCLEAR REGULATORY WASHINGTON, D.C. 20555-0001 SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION RELATED TO AMENDMENT NO. 225 TO FACILITY OPERATING LICENSE NO. NPF-38 ENTERGY OPERATIONS, INC. WATERFORD STEAM ELECTRIC STATION, UNIT 3 DOCKET NO. 50-382

1.0 INTRODUCTION

By application dated October 19, 2009 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML092940242, Reference 1), Entergy Operations, Inc. (Entergy, the licensee), requested changes to the Technical Specifications (TSs) for Waterford Steam Electric Station, Unit 3 (Waterford 3). The proposed changes would relocate the Waterford 3 Steam Generator Level -High trip requirements from TS Sections 2.2 and 3/4.3.1 to the Technical Requirements Manual (TRM). This relocation of the Steam Generator Level -High trip requirements is consistent with Technical Specification Task Force (TSTF) 41 O-A, "Relocation of Steam Generator Level -High Trip to the TRM," and Revision 3 of NUREG-1432, "Standard Technical Specifications, Combustion Engineering Plants."

2.0 REGULATORY EVALUATION

Section 182a of the Atomic Energy Act of 1954, as amended (the Act), requires applicants for nuclear power plant operating licenses to include TSs as a part of the license. The Nuclear Regulatory Commission's (NRC) regulatory requirements related to the content of TS are set forth in Title 10 of the Code of Federal Regulations (10 CFR), Section 50.36, "Technical specifications," which requires that the TSs include items in specific categories, including (1) safety limits, limiting safety system settings, and limiting control settings; (2) limiting conditions for operation (LCOs); (3) surveillance requirements (SRs); (4) design features; and (5) administrative controls.

The regulations in 10 CFR 50.36(c)(2)(i) state that the TSs will contain LCOs which "are the lowest functional capability or performance levels of equipment required for safe operation of the facility.

When a limiting condition for operation of a nuclear reactor is not met, the licensee shall shut down the reactor or follow any remedial action permitted by the technical specifications until the condition can be met." The regulations in Enclosure 2

-10 CFR 50.36(c)(2)(i) state that an LCO must be established for each item meeting one or more of the following criteria: Installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary; A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier; A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier; A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety. Therefore, existing TS LCOs and related SRs that fall within or satisfy any of these criteria, must be retained in the TSs, while those TS requirements that do not fall within or satisfy these criteria may be relocated to other, licensee-controlled documents.

The NRC staff also evaluated the proposed changes against the following criteria in 10 CFR 50.36(c)(2)(ii): (A) Criterion

1. Installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.

(8) Criterion

2. A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. (C) Criterion
3. A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. (0) Criterion
4. A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety. TECHNICAL EVALUATION

3.1 Proposed

TS Changes As stated in its letter dated October 19, 2009, the licensee proposed the following changes: Relocate the trip setpoints and allowable values for Functional Unit 11, "Steam Generator Level-High," from TS Table 2.2-1 to the Waterford 3 TRM (page 2-3);

-3Relocate the Functional Unit 11, "Steam Generator Level -High" requirements of TS Table 3.3-1 to the Waterford 3 TRM (page 3/4 3-3); Relocate Note (g) in TS Table 3.3-1 (steam generator high level trip bypass) to the Waterford 3 TRM (page 3/4 3-4); Relocate references to the Steam Generator Level -High functional units from Actions 2 and 3 of TS Table 3.3-1 to the Waterford 3 TRM (pages 3/4 3-5 and 3/43-6); Relocate the Functional Unit 11, "Steam Generator Level -High" surveillance requirements of TS Table 4.3-1 to the Waterford 3 TRM (page 3/4 3-10); Relocate references to "Steam Generator Level -High" from Actions 19 and 20 of TS Table 3.3-3 to the Waterford 3 TRM (page 3/4 3-18b); and Relocate the TS Bases in Section 2.2.1 for "Steam Generator Level-High" trip setpoint to the Waterford 3 TRM. In addition, Table Notation (4) of TS Table 2.2-1 will be retained in the TSs, but will be copied to the Waterford 3 TRM. NRC Staff Evaluation The reactor protection system "Steam Generator Level -High" trip function is provided to protect the main turbine from excessive moisture carryover from the steam generators that may result in damage to the turbine in the event of a feedwater transient.

During a feedwater malfunction, the steam generator level may rise to the point that excessive moisture entering the steam line could cause potential damage to components within the main turbine and failure of the turbine itself. The moisture mist entering the steam line could cause increased vibration, blade wear, and eventual permanent damage to the main turbine. Therefore, upon the steam generator level exceeding the steam generator high level trip setpoint, a reactor trip is initiated, which in turn automatically trips the main turbine. However, the main turbine is not a safety-related component and its loss does not impact the safety of the reactor core. The high steam generator level trip function does not act to protect the reactor core. This trip function is not credited in any design-basis accident and transient analysis, nor does it correspond to any safety limit. The steam generator high level trip function was evaluated against the four criteria stated in 10 CFR 50.36(c)(2)(ii).

The NRC staff's evaluation determined the following: The steam generator high level trip does not provide control room instrumentation that is used to detect a significant abnormal degradation of the reactor coolant pressure boundary.

Based on the licensee's November 22, 1994, response (Reference

2) to NRC Generic Letter (GL) 89-19, "Safety Implication of Control Systems in LWR Nuclear Power Plants," dated September 20, 1989 (ADAMS Legacy Library Accession No. 890920223), appropriate provisions have been met and maintained which adequately

-4 address the concerns of GL 89-19 without the reliance on the steam generator high level trip function. The steam generator high level trip is not a process variable, design feature, or operating restriction that is an initial condition of a design-basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The steam generator high level trip function supports main turbine protection and is not credited in any accident analyses nor does it correspond to any safety limit. The steam generator high level trip is not a structure, system, or component that is part of the primary success path which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The steam generator high level trip function provides main turbine protection and is not analyzed to mitigate the consequences of a design-basis accident that threatens the integrity of a fission product barrier. The steam generator high level trip is not a structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety. The steam generator high level trip function supports main turbine protection.

In its response to GL-89-19 (Reference 2), the licensee stated that it had reviewed the Combustion Engineering Owners Group's (CEOG) report and verified that the generic aspects of the report are applicable to Waterford

3. As discussed in its January 3, 1995, safety evaluation (Reference
3) on the CEOG's response to GL 89-19 regarding the steam generator overl:ill protection, the NRC staff accepted the CEOG's contention from a probabilistic risk assessment viewpoint that steam generator overfill events do not have a significant impact on the public health and safety. The Waterford 3 Final Safety Analyses Report (FSAR), Section 13.7.1.2, states that the TRM is administered as part of the FSAR, changes to the TRM are subject to the criteria of 10 CFR Section 50.59, "Changes, tests and experiments," and administrative controls for processing TRM changes are included in the Waterford 3 site procedures.

Therefore, the NRC staff concludes that sufficient regulatory controls exist for the TRM. Based on the above, the NRC staff concludes that the proposed TS changes are acceptable.

The NRC has also concluded that sufficient controls exist to maintain regulatory requirements via the TRM. Summary The NRC staff concludes that the above requirements associated with the steam generator high level trip function may be deleted from the TSs because (1) the 10 CFR 50.36 TS inclusion criteria are not applicable to the steam generator high level trip function, and (2) these requirements have been appropriately relocated to the licensee's TRM. The NRC staff has reviewed the licensee's request to relocate the portions of the Waterford 3 TSs associated with the steam generator high level trip function to the TRM and, based on its evaluation, the staff concludes that the requested TS changes are acceptable.

-In addition, the staff concludes that the licensee has provided adequate justification to support the requested changes and reasonable assurance that Waterford 3 will be able to comply with the regulatory requirements and, therefore, meets 10 CFR 50.36. Therefore, the NRC staff concludes that the proposed TS changes are acceptable. Regulatory Commitments In its letter dated October 19, 2009, the licensee made the following commitment:

Upon NRC approval of the proposed TS change, Entergy will relocate Waterford 3 Steam Generator Level -High trip function to the Technical Requirements The NRC staff concludes that the proposed commitment is acceptable. STATE CONSULTATION In accordance with the Commission's regulations, the Louisiana State official was notified of the proposed issuance of the amendment.

The State official had no comments. ENVIRONMENTAL CONSIDERATION The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20. The NRC staff has determined that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure.

The Commission has previously issued a proposed finding that the amendment involves no significant hazards consideration, and there has been no public comment on such finding published in the Federal Register on December 1, 2009 (74 FR 62834). Accordingly, the 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 the issuance of the amendment. CONCLUSION The Commission has concluded, based on the considerations discussed above, that: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendments will not be inimical to the common defense and security or to the health and safety of the public.
