High Temperature Gas-cooled Reactor Technology Training Curriculum
July 16-17, 2019
The NRC arranged for Idaho National Laboratory (INL) to develop and present a training course on high-temperature gas-cooled reactors (HTGRs). The course provides background on various HTGR concepts presently under development, including a history of earlier HTGR projects, descriptions of conceptual designs, and expected technical and regulatory challenges.

High Temperature Gas Reactors: Assessment of Applicable Codes and Standards

October 2015

This document represents an update to the original version of this report on the subject code and standards for high temperature gas reactor applications. In particular this report addresses the comments provided by INL and documented in TEV-1463 Rev. 0 (INL, 2012). In addition, this report includes updated information on codes and standards for high temperature gas cooled reactors (HTGRs) at the time of writing, as well as additional information on leak-before break (LBB) issues as applied to HTGRs, and foreign codes and standards.

2015 Report

October 2011

Current interest expressed by industry in HTGR plants, particularly modular plants with power up to about 600 MW(e) per unit, has prompted NRC to task PNNL with assessing the currently available literature related to codes and standards applicable to HTGR plants, the operating history of past and present HTGR plants, and with evaluating the proposed designs of RPV and associated piping for future plants.
