What the agency says
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft Regulatory Guide (DG), DG-1436, "Acceptability of ASME Code, Section III, Division 5, "High Temperature Reactors.' " This DG is proposed Revision 3 of Regulatory Guide (RG) 1.87, "Acceptability of ASME Code, Section III, Division 5, 'High Temperature Reactors,' " and describes an approach that is acceptable to the staff of the NRC to assure the mechanical/structural integrity of components that operate in elevated temperature environments and that are subject to time-dependent material properties and failure modes. It endorses, with conditions, the 2023 Edition of the American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel (BPV) Code (ASME Code) Section III, "Rules for Construction of Nuclear Facility Components," Division 5, "High Temperature Reactors," and several related code cases.
