Web1 jul. 2016 · Generation of electricity in a nuclear reactor is similar to a coal-fired steam station. The difference is the source of heat. Fissioning, or splitting, of uranium atoms produces energy in the same way burning coal, gas, or oil is used as a source of heat in fossil fuel power plants. The fuel used in nuclear generation is 235 U and/or 239 Pu. WebCANDU reactors use natural uranium as their nuclear fuel.Natural uranium is composed of about 0.7% uranium-235, and the remaining 99.3% is mostly uranium-238 which …

WebUranium ore refers to naturally occurring rock or mineral deposits that contain a sufficient concentration of uranium, a radioactive element, to make its extraction economically viable. Uranium is a relatively rare element and is typically found in trace amounts in the Earth's crust. Uranium ore is typically mined and processed to extract uranium for various … WebPHWRs (such as CANDU reactors) normally use natural uranium as fuel which has not undergone enrichment and so can operate fuelled by the uranium and plutonium that …

WebUranium 238. Uranium 238, which alone constitutes 99.28% of natural uranium, is the most common isotope of uranium in nature. Uranium 238 has the longest half-life (4.47×10 9 years), and therefore its abundance is so high. Uranium 238 is a fissionable isotope but is not a fissile isotope. 238 U belongs to primordial nuclides because its half ...
