REQUESTS FOR ADDITIONAL INFORMATION FOR THE REVIEW OF THE WATERFORD STEAM ELECTRIC STATION, UNIT 3, LICENSE RENEWAL APPLICATION - SET 17 (CAC NO. MF7492)
Dear Mr. Chisum:
By letter dated March 23, 2016, Entergy Operations, Inc. submitted an application pursuant to Title 10 of the Code of Federal Regulations Part 54, to renew the operating license NPF-38 for Waterford Steam Electric Station, Unit 3. The staff of the U.S. Nuclear Regulatory Commission (NRC or the staff) is reviewing the information contained in the license renewal application and has identified areas where additional information is needed to complete the review.
The enclosed requests for additional information were discussed with Mr. Alan Harris and a mutually agreeable date for the response is within 30 days from the date of this letter. If you have any questions, please contact me at 301-415-6447 or by e-mail at Phyllis.Clark@nrc.gov.
Sincerely, Phyllis Clark 1

WATERFORD STEAM ELECTRIC STATION, UNIT 3 LICENSE RENEWAL APPLICATION REQUESTS FOR ADDITIONAL INFORMATION - SET 17 (CAC NO. MF7492)
RAI 4.3.3-2a
Background:
By letter dated October 12, 2016, the staff issued RAI 4.3.3-2, requesting the applicant to provide additional information on its methodology to identify and evaluate plant-specific locations for environmentally-assisted fatigue (EAF). By letter dated December 12, 2016, the applicant responded to RAI 4.3.3-2 stating that its methodology will be based on EPRI Report 1024995, Environmentally Assisted Fatigue Screening, Process and Technical Basis for Identifying EAF Limiting Locations. The applicant stated that this screening process will determine the sentinel locations that will bound and appropriately represent each thermal zone.
Per 10 CFR 54.29(a)(1), the staff needs reasonable assurance that the effects of aging will be managed for the period of extended operation. In addition, per SRP-LR Section 4.3.2.1.3, the applicant should address the effects of the coolant environment on component fatigue life. One acceptable approach (which the applicant is using) is to assess the impact on a sample of critical components. This sample should include, as a minimum, those selected in NUREG/CR 6260. Applicants should also consider adding additional plant specific component locations if the locations might be more limiting than those in NUREG/CR-6260.
The applicant has not provided reasonable assurance that their methodology will successfully and appropriately identify plant-specific component locations that may be more limiting than those identified in NUREG/CR 6260.
Issue:
As of April 2016, EPRI Technical Report 1024995 has not been submitted to the NRC for review and approval and, therefore, has not been endorsed by the NRC. The applicant did not define a plant-specific methodology and criteria to select the most limiting locations for EAF. The licensee has not demonstrated that a plant-specific screening methodology has been developed in a manner that conservatively evaluates EAF effects, with the same degree of analytical rigor for all locations, to identify the bounding locations.
For the step in the methodology that computes the estimated EAF value (Uen*), the applicant stated that it will calculate Uen* using a fatigue correction factor (Fen) that is the average of the Fen determined for the strain rate of the predominant thermal transient and the maximum Fen determined by the minimum strain rate. The term predominant thermal transient is not defined, nor how the predominant thermal transient will be determined for each component. Further, the applicant does not provide a basis for why the resulting Uen* is a conservative value that can be used to compare the locations in an appropriate manner. Also, within each thermal zone, the applicant stated that the CUF values are determined on a common basis (i.e., unbundled transients) so that valid rankings can be achieved. The staff is unclear what specific
parameters will be used. The staff needs additional information to determine if the components will be assessed similarly.
For the step in the methodology that examines the relative rankings and selects the sentinel locations, the staff also needs additional information to determine if the applicant selection of sentinel locations within a thermal zone is conservative and appropriate. The applicant did not define the specific selection criteria in its further study to determine the sentinel locations.
Also, the staff is unclear on the term, close-coupled, in terms of determining the number of sentinel locations within a thermal zone.
The applicant also did not clarify if material type is one of the criteria when selecting sentinel locations (i.e., a sentinel location of one material can bound a location of a different material within a thermal zone). The staff noted that the Uen* of different materials may respond differently when the EAF is being refined in the future. The staff noted that refinement of the Uen* value sentinel location of one material may not correspond to an equivalent reduction of the Uen* value of a bounded location of a different material. The applicant did not justify that the refinement of the higher Uen* of one material would ensure the reduction of Uen* values for another material within the same transient section.
Request:
- 1. Confirm if components in different thermal zones will be compared to each other. If they will be or can be, describe the methodology that will be used to make the comparison, including any assumptions, and provide a technical justification that the comparison can be made in an appropriate manner.
- 2. For the step in the methodology that compares locations within a thermal zone:
- a. Define the term, predominant thermal transient, and how it will be determined for each component.
- b. Justify that calculating the Uen* using an average Fen is conservative and appropriate.
- c. In addition to use of unbundled transients, define other relevant parameters that will be used to ensure that the CUF values can be determined on a common basis (i.e.,
amount of rigor, use of the same ASME code fatigue curves).
- d. Justify that the parameters used above will provide a conservative and appropriate comparison between locations within the same thermal zone.
- 3. For the step in the methodology that selects sentinel locations:
- a. Define the term, close-coupled, and how it will be applied in determining the number of sentinel locations within a thermal zone.
- b. Provide the selection criteria that will be applied to each thermal zone to select the sentinel locations.
- c. If material type is not a selection criterion (i.e., a sentinel location of one material can bound a location of a different material within a thermal zone), justify that the refinement of the Uen* value of a sentinel location of one material would ensure the reduction of the Uen* of a bounded location of a different material.
