The integral fast reactor
- Argonne National Lab., IL (United States)
The Integral Fast Reactor (IFR) is an innovative liquid metal reactor concept being developed at Argonne National Laboratory. It seeks to specifically exploit the inherent properties of liquid metal cooling and metallic fuel in a way that leads to substantial improvements in the characteristics of the complete reactor system. The IFR concept consists of four technical features: (1) liquid sodium cooling, (2) pool-type reactor configuration, (3) metallic fuel, and (4) an integral fuel cycle, based on pyrometallurgical processing and injection-cast fuel fabrication, with the fuel cycle facility collocated with the reactor, if so desired. The single most significant property of liquid metal cooling is that it allows an atmospheric-pressure primary system. There is ample margin between the boiling temperature of sodium ({approximately}900 {degrees}C) and the coolant operating temperature (typically 350 {degrees}C inlet and 510 {degrees}C outlet). The thick-walled pressure vessels that are needed to contain the high pressures in water cooled systems are unnecessary here. This in turn allows a pool configuration with its accompanying large thermal inertial. To fully capitalize on the potential advantage offered by these properties requires complementary selection of fuel material. 23 refs., 7 figs., 5 tabs.
