Web5 okt. 2016 · The nuclear reactors that use the regular water in a purified form are called Light Water Reactors. On the other hand, some reactors such as CANDU (Canada Deuterium Uranium), employ natural Uranium, which is not enriched, and use “heavy water”. They are called Heavy Water reactors. Contents hide Light Water Reactors Heavy … WebPlutonium-239 is primarily used as a fuel to power nuclear reactors. In fact, it enters into the composition of MOX fuel – mixed uranium and plutonium oxide. By combining the Pu 239 produced by nuclear reactors with depleted uranium, MOX can be used to fabricate one new fuel assembly from every 8 used fuel assemblies.
