MEMORANDUM TO:
Mohammed Shams, Director Division of Advanced Reactors and Non-Power Production Utilization Facilities Office of Nuclear Reactor Regulation FROM:
Louise Lund, Director Division of Engineering Office of Nuclear Regulatory Research
SUBJECT:
TECHNICAL LETTER REPORT (TLR-RES/DE/REB-2022-11) GRAPHITE DEGRADATION MODELING AND ANALYSIS The technical letter report Graphite Degradation Modeling and Analysis has been completed and is to be published on the Agencywide Documents Access and Management System (ADAMS) under ADAMS accession number ML22346A082. The report was completed as a part of work aimed at developing expertise and tools to model graphite behavior in advanced non-light water reactors.
The report describes a tool developed at Idaho National Laboratory for the assessment of graphite components. The tool includes models for thermo-mechanical and oxidation behaviors. A reliability model implementing the American Society of Mechanical Engineers Boiler and Pressure Vessel Code,Section III, Division 5 is used for final assessment. The report also includes a user guide that describes how to use the tool.
Staff representatives from the Division of Advanced Reactors and Non-Power Production and Utilization Facilities have reviewed a draft of this TLR, and the enclosed final TLR reflects the resolution of their comments. Nonetheless, please feel free to notify the responsible RES contact if you have any questions concerning the impending public release of this TLR.
RES has established an online quality survey to collect feedback from user offices on the usefulness of RES products and services. This survey can be found online at the hyperlink: RES Quality Survey.
