Gas-cooled Fast Reactor

A Gas-cooled Fast Reactor (GFR) is a type of nuclear reactor that uses fast neutrons to sustain a chain reaction and employs helium gas as its coolant. Unlike traditional reactors that slow down neutrons with water, GFRs operate at high temperatures with minimal moderation, enabling efficient fuel use and waste reduction. They are designed to produce electricity efficiently and can utilize various fuel types, including recycled materials, making them potentially more sustainable. The helium coolant is chemically inert and doesn't become radioactive, contributing to safety and longevity of the reactor.
