Background:
By letter dated December 8, 2016, the staff issued RAI B.1.34-1a regarding the absence of a staff-approved withdrawal schedule for Capsule 277° (i.e., the surveillance capsule representing the period of extended operation). In its response dated January 19, 2017, the applicant identified a program exception to GALL Report AMP XI.M31, Reactor Vessel Surveillance. The program exception, in part, indicates that the applicant will submit the revised capsule withdrawal schedule separate from the license renewal application, but prior to implementation.
In its previous letter dated November 10, 2016 (i.e., response to RAI B.1.34-1), the applicant stated that, for the capsule located at 277°, WCAP-18002-NP suggested a removal time of the reactor vessel refueling outage nearest to 48 EFPY. The applicant also stated that the estimated fluence for the capsule at 48 EFPY is 4.51x1019 n/cm2 providing a fluence greater than the reactor vessel inner radius fluence calculated for 55 EFPY of 4.32x1019 n/cm2.
Issue:
In its response, the applicant did not describe the current EFPY of the unit as baseline information. In addition, the staff notes that, since the Reactor Vessel Surveillance Program is an existing program as required by Appendix H to 10 CFR Part 50, the program establishes and maintains staff-approved reactor vessel surveillance capsule withdrawal schedules for the license term. Given the applicants program exception that a withdrawal schedule for Capsule 277° is not submitted as part of the license renewal application, the staff notes that Waterford Unit 3 should submit the capsule withdrawal schedule for staffs review and approval (in accordance with 10 CFR Part 50, Appendix H) within a specific time period following the receipt of a renewed license (e.g., within 1 year following the receipt of a renewed license).
Request:
- 1. Provide the current EFPY of the unit.
- 2. Identify a program enhancement to submit a withdrawal schedule for Capsule 277° for staffs review and approval (in accordance with 10 CFR Part 50, Appendix H) within a specific time period following the receipt of a renewed license (e.g., within 1 year following the receipt of a renewed license). If such a program enhancement is not necessary, provide justification.

- 2. The Reactor Vessel Surveillance Program will be enhanced to specify submittal of a withdrawal schedule for review and approval within one (1) year following the receipt of the renewed license. The surveillance capsule located at 277° will be removed at approximately 48 EFPY with a neutron fluence of between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended operation.
LRA Section A.1.34, Reactor Vessel Surveillance Program, LRA Section A.4 License Renewal Commitment List, LRA Table B-3, WF3 Program Consistency with NUREG-1801, and LRA Section B.1.34, Reactor Vessel Surveillance, are revised as follows. Additions are underlined; deletions are lined through.

- 1. The Reactor Vessel Surveillance Program includes a commitment to specify submittal of a withdrawal schedule for review and approval within one (1) year following the receipt of a renewed license. The surveillance capsule located at 277° will be removed at approximately 48 EFPY with a neutron fluence of between one and two times the peak reactor vessel wall neutron fluence at the end of the period of extended operation.WF3 commitment management system includes a commitment to submit a reactor vessel surveillance capsule withdrawal schedule for future removal of the capsule located at 277°. The commitment specifies submitting the schedule along with its technical justification for NRC approval. In accordance with 10 CFR 50, Appendix H, Entergy will obtain NRC approval of the revised reactor vessel surveillance capsule withdrawal schedule prior to implementation.
