March .3, 2023 MEMORANDUM TO: Luis Betancourt, Chief Accident Analysis Branch Division of Systems Analysis Office of Nuclear Regulatory Research Signed by Nosek, Andrew FROM: AJ Nosek, Reactor Systems Engineer on 03/03/23 Accident Analysis Branch Division of Systems Analysis Office of Nuclear Regulatory Research
SUBJECT:
COMPLETION OF WHITE PAPER, MACCS CONSEQUENCE ANALYSIS DEMONSTRATION CALCULATIONS FOR AN EXAMPLE HEAT PIPE REACTOR SOURCE TERM The Office of Nuclear Regulatory Research (RES) staff completed an evaluation to demonstrate the capabilities of the MACCS code in analyzing the offsite consequences of an example postulated heat-pipe reactor (HPR) accident release, which is available in the Agencywide Documents Access and Management System (ADAMS) under Accession Number ML23045A044. This report describes a demonstration of MACCS capabilities using as input the core radionuclide inventory and atmospheric release from example SCALE and MELCOR demonstration calculations by Oak Ridge National Laboratories (ADAMS Accession No. ML22158A054) and Sandia National Laboratories (ADAMS Accession No. ML22144A188),
respectively, for a publicly available heat-pipe-reactor conceptual design.
The results of our evaluation confirm that the MACCS code is flexible in analyzing the offsite consequences of an example postulated HPR accident release. The code includes flexible input decks that can be made plant-specific, site-specific, and accident specific by modifying a subset of input parameters and input files. As new information becomes available, RES staff may assess whether further enhancements to the MACCS code are needed.
