Gas Cooled Fast Reactor

Conclusions: • The GFR concept is attractive as it avoids the coolant handling issues associated with liquid metal-cooled fast reactors: - Helium chemically inert; - Excellent nuclear stability avoids activation of the coolant; - Transparent coolant permits simple inspection and repair. • GFR offers a high temperature heat source for high efficiency electricity generation and high-quality process heat. • The main technical challenges lie in the development of a high-temperature, high-power density fuel and in the development of robust decay heat removal systems.
