October 5, 2023 Mrs. Joy L. Rempe, Chairman Advisory Committee on Reactor Safeguards U.S. Nuclear Regulatory Commission Washington, DC 20555-0001
SUBJECT:
RESPONSE TO ADVISORY COMMITTEE ON REACTOR SAFEGUARDS LETTER ON ITS REVIEW OF REGULATORY GUIDE 1.183, REVISION 1, ALTERNATIVE RADIOLOGICAL SOURCE TERMS FOR EVALUATING DESIGN BASIS ACCIDENTS AT NUCLEAR POWER REACTORS
Dear Chairman Rempe:
The purpose of this letter is to provide the U.S. Nuclear Regulatory Commission (NRC) staff's response to the Advisory Committee on Reactor Safeguards (ACRS) letter dated September 20, 2023, (Agencywide Documents Access and Management System (ADAMS)
Accession No. ML23256A179), whereby the ACRS reported on its review of the NRC staffs Regulatory Guide (RG) 1.183, Revision 1, Alternative Radiological Source Terms for Evaluating Design Basis Accidents at Nuclear Power Reactors.
In its letter, the ACRS recommended that RG 1.183, Revision 1, should be issued. Based on the information provided to the ACRS and discussions during the September 6, 2023, ACRS Full Committee meeting with external stakeholders and the NRC staff, the ACRS noted that the following two topics should also be addressed:
(1) Because of the need for regulatory stability relative to the use of alternative source terms (including high burnup and high enriched fuels), a single version (Revision 2) of the RG should be developed. The schedule for this development should be aligned with the upcoming rulemaking on increased enrichment.
(2) The staff should consider detailed comments in the September 20 letter related to alignment with emergency preparedness guidance, rationale associated with the RG, and the need for capturing lessons learned during implementation.
The NRC staff recognizes the ACRS conclusions and recommendations and will ensure there is appropriate consideration of these topics in future updates to this regulatory guidance or related documentation. The NRC staff appreciates the ACRSs timely and thorough review of RG 1.183, Revision 1, which is available in ADAMS (ML23082A305) and is expected to be issued in October 2023.
J. Rempe Sincerely, Kock, Andrea signing on behalf of Veil, Andrea on 10/06/23 Andrea D. Veil, Director Office of Nuclear Reactor Regulation cc: Chairman Hanson Commissioner Caputo Commissioner Crowell Commissioner Wright
