WebJul 13, 2024 · This Working Group was created in 1978, with the purpose of advising the IAEA on how to promote the exchange of technical information and international cooperation on gas cooled reactors, in particular for … A high-temperature gas-cooled reactor (HTGR), is a nuclear reactor that uses a graphite moderator with a once-through uranium fuel cycle. The HTGR is a type of high-temperature reactor (HTR) that can conceptually have an outlet temperature of 750 °C (1,380 °F). The reactor core can be either a "prismatic … See more The HTGR is a type of high-temperature reactor that conceptually can reach high outlet temperatures (up to 750 °C). There are two main types of HTGRs: pebble bed reactors (PBR) and prismatic block reactors … See more The HTGR design was first proposed by the staff of the Power Pile Division of the Clinton Laboratories (known now as Oak Ridge National Laboratory ) in 1947. Professor See more The design takes advantage of the inherent safety characteristics of a helium-cooled, graphite-moderated core with specific design optimizations.
