Argonne National Laboratory Experimental Breeder Reactor II, EBR II, and Integral Fast Reactor, IFR The Experimental Breeder II or EBR II reactor was the prototype for the Integral Fast Reactor (IFR), a reactor fueled by metal alloy and cooled by liquid sodium. This video describes the fuel fabrication and recycling for the Integral Fast Reactor developed at Argonne National Laboratory. These are key factors to the success of this nuclear power technology that can meet a lot of the world’s electrical energy needs for a long time to come. https://www.youtube.com/watch?v=cBThTwFhRlA
