Dear Sir or Madam:
In Reference 1, 2, and 3, Entergy Operations, Inc. (Entergy) proposed a change to the Arkansas Nuclear One Unit 2 (ANO-2) and Waterford Steam Electric Station Unit 3 (Waterford 3) Technical Specifications (TSs) associated with the Core Operating Limits Report (COLR) references.
2CAN051 001 Page 2 of 3 During the submittal review process, the Nuclear Regulatory Commission (NRC) determined that Requests for Additional Information (RAls) was required to complete the review of the Entergy submittals (Reference 4 and 5).
A draft of the responses to the RAIs was previously provided to the NRC. During the review of these draft responses, additional clarifications were provided in conference calls between the NRC and the two subject Entergy sites. The responses, in accordance with the aforementioned clarifications, are included in Attachment 1 to this letter. Attachments 2 and 3 contain revised markups of affected TS pages for ANO-2 and Waterford 3, respectively.
This letter contains no new commitments. The response is intended to support both the ANO-2 and Waterford 3 amendment requests.
If you have any questions or require additional information, please contact David B. Bice at (479) 858-5338 (ANO) or William J. Steelman at (504) 739-6685 (Waterford 3).
I declare under penalty of perjury that the foregoing is true and correct.

Waterford'3 Records Center (W-GSB-1 00) to 2CAN051001 Response to Request for Additional Information to 2CAN051001 Page 1 of 6 NRC REQUEST FOR ADDITIONAL INFORMATION The following lists Nuclear Regulatory Commission (NRC) Request for Additional Information (RAI) and the Arkansas Nuclear One Unit 2 (ANO-2) and the Waterford Steam Electric Station Unit 3 (Waterford 3) responses associated with the respective Core Operating Limits Report (COLR) reference submittals.
ANO-2 Request [Reference 61 Based on the guidance specified in Generic Letter 88-16 (GL 88-16), each approved methodology listed in Technical Specification (TS) 6.6.5.b should support a calculation for a cycle-specific core operating limit listed in TS 6.6.5.a. In other words, the methodologies listed in TS 6.6.5.b should identify its supporting role for the cycle-specific parameters listed in TS 6.6.5.a, in orderto be qualified as a part of TS 6.6.5.b.
Please provide:
(a) a description to explain why no date of approval and use of the approved methodologies are proposed for TS 6.6.5.b; (b) identification of cycle-specific parameter listed in TS 6.6.5.a corresponding to an approved methodology listed in TS 6.6.5.b with respect to a real application to the current reload analysis; and (c) a justification that all the proposed methodologies are qualified to be listed in TS 6.6.5.b.
Waterford 3 Request [Reference 71 The NRC staff has reviewed the application and determined that the following information is needed to complete its review:
- 1.
With respect to the list of core operating limits listed in Insert 1 in Attachment 2 to the May 22, 2009 letter, please provide the following information:
A clarification that the proposed list consists of all independent cycle-specific core operating limits; 0
A description of the relationship between TS 3.2.1, "Linear Heat Rate," and TS 3.6.1.5, "Air Temperature, Containment"; and The reason why a parenthesis (Linear Heat Rate, 3.2.1) follows TS 3.6.1.5.
- 2.
Based on the guidance specified in GL 88-16, each approved methodology listed in TS 6.9.1.11.1 should support a calculation for a cycle-specific core operating limit listed in the proposed Insert 1. It appears that the list of analytical methodologies in proposed Insert 2 in Attachment 2 to the May 22, 2009, letter is not in compliance with GL 88-16 guidance; therefore, please provide the following information:
Describe how each of the five methodologies listed in Insert 2 (e.g., Nuclear Engineering Methodologies) support the Insert 1 cycle-specific parameters; to 2CAN051001 Page 2 of 6 Describe the relationship between the cycle-specific parameters in proposed Insert 1 and the methodologies in proposed Insert 2; and Provide justification that all of the analytical methodologies listed in proposed Insert 2 are qualified to be listed in TS 6.9.1.11.1.
Further clarifications were obtained via several conference calls between the NRC and Entergy over the last few months. During one of the calls, following a discussion related to a draft response to address the above questions, it was agreed that the draft response would be acceptable provided Entergy Operations, Inc. (Entergy) agrees to retain the parenthetical ties currently listed in the COLR. Entergy had previously proposed to delete this information from the COLR TS. As a result of this call, Entergy agreed to formally submit the draft response letter once modified to retain the aforementioned parenthetical ties.
RESPONSE
The ANO-2 and Waterford 3 methods listed in the response are from the COLR changes submitted in letter 2CAN 110901 (ANO-2) [Reference 3] and W3F1-2009-0017 (Waterford 3)
[Reference 5].
The response to ANO-2 Request Part (a) provides the background information and justification for not including approval dates of the listed methodologies, as previously approved by the NRC [Reference 3]. However, with regard to describing the use of each methodology, Entergy agrees that this information may be retained in the TSs without undue burden to the licensee.
As a result, revised markup pages of the affected TS pages are included in Attachment 2 of this letter.
The response to Waterford 3 Request Part 2 of Question 1 associated with the relationship between containment air temperature and linear heat rate is contained within a previous submittal letter W3F1-2007-0037 [Reference 8].
W3F1-2007-0037 states that the limitation on containment minimum average air temperature ensures that the Emergency Core Cooling System (ECCS) is capable of maintaining a Peak Clad Temperature (PCT) less than or equal to 2200°F during large break Loss of Coolant Accident (LBLOCA) conditions. A higher containment average air temperature results in a higher post accident containment pressure, a higher reflood rate, and therefore a lower PCT.
With regard to Waterford 3 Request Part 1 and 3 of Question 1, the proposed list consists of all independent cycle specific core operating limits. The parenthesis (Linear Heat Rate, 3.2.1) was added for clarification because TS 3.6.1.5 is tied to the TS 3.2.1 COLR requirements.
TS 3.2.1 COLR restricts linear heat rate requirements when TS 3.6.1.5 Action A is entered.
Based upon one of the aforementioned conference calls with the NRC, the response to ANO-2 Request Part (b) and (c) and Waterford 3 Request Question 2 will be limited to a summary of the methodologies used for each parameter.
A summary of how the listed methodologies and analyses for a given parameter are used to determine the associated operating limit listed in the COLR is provided below.
to 2CAN051 001 Page 3 of 6 SHUTDOWN MARGIN The value for Shutdown Margin (SDM) is determined via the PHOENIX-P / ANC methodology.
The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC). The NRCapproved the PARAGON topical for this purpose.
The cycle specific value for SDM is confirmed by the transient analyses performed in accordance with the CENTS methodology to meet all appropriate licensing criteria provided the COLR-specified SDM is maintained.
MODERATOR TEMPERATURE COEFFICIENT The values for Moderator Temperature Coefficient (MTC) are determined via the PHOENIX-P / ANC methodology. The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC). The NRC approved the PARAGON topical for this purpose.
The values for MTC determined as stated above are confirmed by the large break and small break LOCA (LBLOCA and SBLOCA) and the transient code (CENTS). The Zirconium Diboride (poison), fuel cladding (ZIRLO and Optimized ZIRLO) and the design of the fuel assembly (Next Generation Fuel [NGF]) analyses have a secondary (minor) effect on the specific values and, therefore, are also used to confirm the MTC values to be acceptable throughout the new operating cycle.
The applicability of the methodologies listed above for the NGF and reactor cores incorporating NGF assemblies is documented in the NGF topical. The NRC Safety Evaluation (SE) for the NGF topical contained a condition requiring the NGF topical to be included in the COLR listing.
CEA POSITION The transient analyses performed using the CENTS methodology demonstrate that all appropriate licensing criteria is met assuming the plant is operated within the COLR-specified power reduction requirements for Control Element Assembly (CEA) position deviations.
INSERTION LIMITS The CEA insertion limits are specified following an iterative process that balances reactivity management during normal operations with the consequences of off-normal occurrences that initiate from partially rodded conditions. The transient analyses are performed in accordance with the CENTS and CEA Ejection methodologies to confirm the effects of CEA insertion.
to 2CAN051 001 Page 4 of 6 The cycle specific effects of CEA insertion on the reactor core are determined via the PHOENIX-P / ANC methodology. The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC). The NRC approved the PARAGON topical for this purpose.
LINEAR HEAT RATE The Linear Heat Rate (LHR) limits are specified following an iterative process that balances fuel rod power peaking with the consequences of off-normal occurrences that initiate from peak fuel rod power conditions. LBLOCA and SBLOCA, which use as input certain outputs from the Fuel Rod Design analysis, demonstrate that all appropriate licensing criteria are met assuming the plant is operated below the COLR-specified LHR limit.
The Fuel Rod Design analyses (performed in accordance with the Fuel Rod Maximum Allowable Gas Pressure methodology for Waterford only) assume that the peak power fuel rod in the core may operate at the COLR LHR limit for a period of time.
The ZIRLO and'Optimized ZIRLO, and the Zirconium Diboride methodologies have a secondary (minor) impact on the limits and, therefore, are also used to confirm the LHR limit to be acceptable throughout the new operating cycle.
The applicability of the methodologies listed above for the NGF and reactor cores incorporating NGF assemblies is documented in the NGF topical. The NRC SE for the NGF topical contained a condition requiring the NGF topical to be included in the COLR listing.
AZIMUTHAL TILT Tilt limits are specified following an iterative process that balances the need to accommodate some degree of tilt with the consequences of off-normal occurrences that initiate from such tilted conditions. Transient analyses including CEA Ejection (and CENTS for Waterford),
LBLOCA, and SBLOCA demonstrate that all licensing criteria are met assuming the plant is operated within the COLR-specified tilt limits.
The ZIRLO and Optimized ZIRLO, and the Zirconium Diboride methodologies have a secondary (minor) impact on the limits and, therefore, are also used to confirm the tilt values to be acceptable throughout the new operating cycle.
The applicability of the methodologies listed above for the Next Generation Fuel (NGF) and reactor cores incorporating NGF assemblies is documented in the NGF topical. The NRC SE for the NGF topical contained a condition requiring the NGF topical to be included in the COLR listing.
to 2CAN051001 Page 5 of 6 DNBR MARGIN The Departure from Nucleate Boiling Ratio (DNBR) is calculated by using the ABB Critical Heat Flux and the WSSV methodologies for the NGF assembly. The reactor core power distributions used to determine the DNBR are determined via the PHOENIX/ANC methodology. The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC).
The NRC approved the PARAGON topical for this purpose. The Modified Statistical Combination of Uncertainties (MSCU) methodology is used to calculate the uncertainty for the DNBR margins. These uncertainties are associated'with the Core Protection Calculators (CPCs) used to calculate DNBR during power operation. Transient analyses using the CENTS methodology provide input.into the DNBR calculations to demonstrate that the minimum DNBRs predicted to occur during all Anticipated Operational Occurrences (AOOs) remain above the DNBR limit.
The applicability of the methodologies listed above for the NGF and reactor cores incorporating NGF assemblies is documented in the NGF topical. The NRC SE for the NGF topical contained a condition requiring the NGF topical to be included in the COLR listing.
AXIAL SHAPE INDEX Axial Shape Index (ASI) limits are specified following an iterative process that balances the need to define a region of acceptable axial power distribution behavior during normal operation with the consequences of off-normal occurrences that initiated from the defined ASI range.
The MSCU methodology is used to calculate the uncertainty in the ASI range (also a CPC monitored parameter). The LBLOCA and SBLOCA analyses demonstrate that all appropriate licensing criteria are met assuming the plant is operated within the COLR-specified ASI limits.
The ZIRLO, Optimized ZIRLO, and the design of the fuel assembly methodologies have a secondary (minor) impact on the limits and, therefore, are also used to confirm the ASI values to be acceptable throughout the new operating cycle.
The full range of ASIs allowed by the COLR limit is considered in the thermal-hydraulic analyses performed in accordance with the ABB Critical Heat Flux methodology. The Zirconium Diboride (poison) methodology has a secondary (minor) effect on the values and, therefore, is also used to confirm the ASI values to be acceptable throughout the new operating cycle.
BORON DILUTION (Waterford 3 only)
The boron dilution limits are created using reactivity inputs determined via the PHOENIX-P / ANC methodology., The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC). The NRC approved the PARAGON topical for this purpose.
to 2CAN051 001 Page 6 of 6 BORON CONCENTRATION (Waterford 3 only)
The Mode 6 RCS boron concentration limits are created using reactivity inputs determined via the PHOENIX-P / ANC methodology. The neutron cross sections used in ANC are calculated by the PARAGON methodology in lieu of the PHOENIX-P methodology. The primary use of PARAGON is to generate nuclear data for use in Westinghouse core simulator codes (PHOENIX-P / ANC). The NRC approved the PARAGON topical for this purpose.
Conclusion Based on this information, Entergy believes the listed methodologies are relevant and necessary to envelope the processes required to ensure core operating limits are derived and appropriately verified to be acceptable prior to each restart following a core design change (such as a refueling outage). Without the application of any one methodology, the associated final core operating limit may not be sufficient to protect the specified acceptable fuel design limits (SAFDLs).
