During 2017, members of the Nuclear Energy Institute (NEI) ATF Licensing Task Force undertook a review of 10CFR50 excluding the appendices, of selected sections of the Standard Review Plan (SRP), and of selected Regulatory Guides (RG). Following the issuance of the NRC’s first draft plan, Subcommittee 1 was formed under the NEI ATF Licensing Task Force to screen for potential ATF impacts in the 10CFR50 Appendices, the unreviewed sections of the Standard Review Plan, and the reactor-related Regulatory Guides. This document presents the results of the screening completed in 2017 by the NEI ATF Licensing Task Force and in 2018 by Subcommittee 1 of the NEI ATF Licensing Task Force.
