MF1879, MF1880, MF1881, MF1882) RAI 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 applicant's Reactor Vessel Surveillance program because the deleted information is necessary to confirm the program's 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 program's compliance with 10 CFR Part 50, Appendix H.
