The Very High Temperature Reactor
The VHTR is the next generation of high-temperature gas-cooled reactors (HTGRs). The VHTR uses helium as coolant, with design temperatures breaking 1000°C (eventually slated to reach 1500°C). [5] Such high temperatures allow for higher thermal efficiencies (>50%), and therefore more electricity output per unit of nuclear fuel.
