Gas Cooled Fast Reactor

Conclusions: 1. The GFR concept is attractive as it avoids the coolant handling issues associated with liquid metal-cooled fast reactors: - Chemical inertness of helium; - Excellent nuclear stability avoids activation of the coolant; - Transparent coolant permits simple inspection and repair. 2. GFR offers a high temperature heat source for high efficiency electricity generation and high-quality process heat. 4. 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. 5. An indirect combined gas/steam cycle has been chose to be the reference power conversion system as this returns good efficiency with low technological risk and good economics.
