High-Temperature Gas-Cooled Reactor

Nuclear Reactor

A high-temperature gas-cooled reactor, or HTGR, is a type of gas-cooled nuclear reactor that uses uranium fuel and graphite moderation to produce very high reactor core outlet temperatures, between 700 and 950 degrees Celsius. Every HTGR built to date uses helium as its coolant, and a proposed very-high-temperature variant would raise the outlet temperature to as much as 1,000 degrees Celsius. The design is one of the Generation IV reactor concepts.
