Use of nonmandatory Appendix A, “Alternate Requirements for NDE and Monitoring,” is not endorsed by the NRC, and use of Appendix A will need to be submitted to the NRC for review and approval. Use of Appendix A may involve complex analysis and warrants review by the NRC to ensure that NDE and monitoring continue to provide adequate safety. The OARs and NIS-2 forms that are generated through implementation of the RIM program, along with any analytical evaluations of inspection results that are conducted in accordance with ASME Code, Section XI, Division 2, should be submitted to the NRC. Although ASME Code, Section XI, Division 2 specifies in nonmandatory Appendix B, “Regulatory Administrative Provisions for Nuclear Plants Using RIM Program,” to submit the OAR 90 days after completion of an outage, the staff finds120 DG-1383, Page 9 days to be acceptable as the 120-day frequency is consistent with ASME Code, Section XI, Division 1. This is an administrative process that should be the same for non-LWR as for LWR licensees and providing this information within 120 days after an outage has been found by the NRC staff to be acceptable for licensees implementing Division 1 without placing undue burden on the licensee. For plants that do not have regularly scheduled refueling outages at frequencies of 5 years or less, applicants should propose frequencies for the submission of OARs and NIS-2 forms.
