Liquid Fuel Nuclear Reactors

The American Physical Society forum on Physics and Society has just published its quarterly newsletter, containing two articles about nuclear power, including one by Robert Hargraves and Ralph Moir, Liquid Fuel Nuclear Reactors. Today’s familiar pressurized water nuclear reactors use solid fuel -- pellets of uranium dioxide in zirconium fuel rods bundled into fuel assemblies. These assemblies are placed within the reactor vessel under water at 160 atmospheres pressure and a temperature of 330°C. This hot water transfers heat from the fissioning fuel to a steam turbine that spins a generator to make electricity. Alvin Weinberg invented the ...
