Due to the extra thermalization, these types can use natural uranium /unenriched fuel. 25 Not all reactors need to be shut down for refueling; for example, pebble bed reactors, rbmk reactors, molten salt reactors, Magnox, AGR and candu reactors allow fuel to be shifted through the reactor while it is running. The government has ignored these recommendations. 7, 25 September 2003": "Etienne Pochon, CEA director of nuclear industry support, outlined EPR's improved performance and enhanced safety features compared to the advanced Generation II designs on which it was based."

See also: Nuclear fission History The neutron was discovered in 1932 by British physicist James Chadwick. The extracted uranium, called yellowcake, undergoes many chemical transformations. Lake open-pit uranium mine in Northern Saskatchewan. Nuclear fuel cycle edit Main article: Nuclear fuel cycle Thermal reactors generally depend on refined and enriched uranium.
