As such, a licensee may find it prudent to save all emergency plan change documentation to facilitate the resolution of such issues. D. IMPLEMENTATION The purpose of this section is to offer information on how applicants and licensees5 may use this guide and information about the U.S. Nuclear Regulatory Commission’s (NRC’s) plans for using this regulatory guide (RG). In addition, it describes how the NRC staff complies with Title 10 of the Code of Federal Regulations (10 CFR) 50.109, “Backfitting,” and any applicable finality provisions in 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.” Use by Applicants and Licensees Applicants and licensees may voluntarily6 use the guidance in this document to demonstrate compliance with the underlying NRC regulations. Methods or solutions that differ from those described in this RG may be deemed acceptable if they offer sufficient basis and information for the NRC staff to verify that the proposed alternative demonstrates compliance with the appropriate NRC regulations. Current licensees may continue to use guidance the NRC found acceptable for complying with the identified regulations as long as their current licensing basis remains unchanged. Licensees may use the information in this RG for actions that do not require NRC review and approval such as changes to a facility design under 10 CFR 50.59, “Changes, Tests, and Experiments.” Licensees may use the information in this RG or applicable parts to resolve
