Mr. Matthew Sunseri, Chairman Advisory Committee on Reactor Safeguards U.S. Nuclear Regulatory Commission Washington, DC 20555-0001
SUBJECT:
REVIEW OF ADVANCED REACTOR COMPUTER CODE EVALUATIONS
Dear Mr. Sunseri:
On behalf of the U.S. Nuclear Regulatory Commission (NRC) staff, I am responding to your letter to Chairman Hanson dated March 1, 2021 (ML21053A024), providing your conclusions and recommendations on the staffs evaluations of computer codes to be used for analyses of advanced non-light-water reactors (non-LWRs). We greatly value the Advisory Committee on Reactor Safeguards (ACRS) review, evaluation and useful perspectives and insights on our approach to code development activities for non-LWRs.
The staff has taken into consideration your recommendations and has revised the two draft documents referenced in your letter that support Strategy 2 of the NRC Non-LWR Near-Term Implementation Action Plans (ML17165A069). Specifically, Volume 4 - Licensing and Siting Dose Assessment Codes (ML21085A484) and Volume 5 - Radionuclide Characterization, Criticality, Shielding, and Transport in the Nuclear Fuel Cycle (ML21088A047) were revised. A list of the revised documents, along with prior related code assessment reports with their Agency Document and Management System (ADAMS) Accession Numbers, is provided at the end of this letter.
The staff looks forward to continued interactions with the ACRS as we prepare for advanced reactor licensing.
Sincerely, Raymond V. Furstenau, Director Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission cc:
