NUCLEAR 101: The sodium-cooled fast reactor uses liquid metal (sodium) as a coolant instead of water that is typically used in U.S. commercial power plants. This allows the coolant to operate at higher temperatures and lower pressures than current reactors—improving the efficiency of the system. Fast reactors use fast-moving neutrons that could allow them to operate on both fissile material and used fuel from current reactors to produce electricity. | Harrisburg100

UPDATE: U.S. Department of Energy selects sodium-cooled fast reactor design for a Versatile Test Reactor in Idaho. If appropriated by Congress, VTR would be the first fast spectrum test reactor to operate in the U.S. in nearly three decades.
