The Integral Fast Reactor (IFR) is a revolutionary reactor design concept developed at Argonne National Laboratory. The IFR is a reactor fueled by metal alloy and cooled by liquid sodium. On April 3, 1986, two tests demonstrated the inherent safety of the IFR concept. These tests simulated accidents involving loss of coolant flow. Even with its normal shutdown devices disabled, the reactor shut itself down safely without overheating anywhere in the system.
