DRAI B.2.1.19-1b Applicability:

Byron Station (Byron) and Braidwood Station (Braidwood), Units 1 and 2

Background:

By letter dated May 23, 2014, the applicant responded to request for additional information (RAI) B.2.1.19-1a that requested an updated surveillance capsule withdrawal schedule for each unit at Byron and Braidwood.

Issue:

In its response, the applicant deleted information regarding the next capsule withdrawal schedule (e.g., capsules and capsule fluences) from the updated final safety analysis report (UFSAR) supplement, program enhancement, and commitment. The staff cannot determine the adequacy of the applicants Reactor Vessel Surveillance program because the deleted information is necessary to confirm the programs compliance with Title 10 of the Code of Federal Regulations (10 CFR) Part 50, Appendix H.

Request:

Provide a basis for the deletion of the information regarding the capsule withdrawal schedule from the UFSAR supplement, program enhancement, and commitment. In addition, provide alternative information upon which the staff could assess the programs compliance with 10 CFR Part 50, Appendix H.

Discussion: The applicant requested clarification on the staffs concern. No edits were made to this request. This question will be sent as a formal request titled: RAI B.2.1.19-1b.
