WebbOur Reactor X-energy’s nuclear reactor designs are based on HTGR technology — a Generation-IV reactor technology with a proven operational pedigree. Xe-100 220,000 Graphite Pebbles with TRISO Particle fuel High temperature tolerant graphite core structure ASME compliant reactor vessel, core barrel & steam generator 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 … Visa mer 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 … Visa mer 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 Rudolf Schulten in Germany also played a role in development during the 1950s.
