Plant Concepts and Mechanisms
This chapter introduces the required functions of the FR, namely, to breed fuel and reduce the toxicity of high-level radioactive waste. It also describes the mechanism of how this is achieved using plutonium and fast neutrons. The use of fast neutrons requires the use of liquid metal sodium as the core coolant. Sodium is also used to transport heat from the reactor core to the steam turbine which results in a unique design condition under which the entire plant becomes a elevated-temperature, low-pressure system.
