Content:
endorsed guidance related to 10 CFR 50.71(e) is out of date which impacts the fleet of operating reactors. Proper implementation of 10 CFR 50.71(e) by the applicant/licensee is essential to the proper maintenance of the design basis and thus impacts requirements for every license amendment approval (~500- 600 a year). Additionally, 10 CFR 50.71(e) governs updates to applications such as the COL DCD and license renewal and subsequent renewal submittals, while under review. Lack of revision of the RG would also not provide new guidance to holders of COLs issued under 10 CFR Part 52. There may also be a need to update guidance to ensure proper 10 CFR 50.59 reviews and implementation of risk-informed TS change processes related to risk-informed completion time and surveillance requirement approvals and in the inspection realm. Additionally, the proper implementation of 10 CFR 50.71(e) is essential to the proper integration of MBDBE into the design basis and other beyond design basis concepts related to 10 CFR 50.54(hh). There is also a backfit component in that a properly updated FSAR is essential to making determination regarding whether a backfit is necessary. The current RG does not comprehensively cover these concepts for compliance for a facility in initial licensing review or construction, currently operating under initial or renewed license, pursuing license renewal, or in decommissioning. - 3 - ENCLOSURE 3.
