SFR – The sodium-cooled fast reactor systems use liquid sodium as the reactor coolant, allowing high power density with low coolant volume fraction. The reactor unit can be arranged in a pool layout or a compact loop layout. Plant size options under consideration range from small (50 to 300 MWe) modular reactors to larger plants (up to 1500 MWe). The two primary fuel recycle technology options are advanced aqueous and pyrometallurgical processing. A variety of fuel options are being considered for the SFR, with mixed oxide for advanced aqueous recycle and mixed metal alloy for pyrometallurgical processing. Owing to the significant past experience accumulated in several countries, SFR systems will be deployed by 2020.
