    Nov 22, 2020 · How Nuclear Power Works . All power plants heat water to produce steam, which turns a generator to create electricity. In nuclear power stations, that steam is made by the heat generated from nuclear fission.   It’s when an atom is split, releasing enormous amounts of energy in the form of heat.

    Nov 23, 2020 · Nuclear power is the second largest source of clean energy after hydropower. The energy to mine and refine the uranium that fuels nuclear power and manufacture the concrete and metal to build nuclear power plants is usually supplied by fossil fuels, resulting in CO2 emissions; however, nuclear plants do not emit any CO2 or air pollution as they operate.

    Assessing The Costs of Nuclear PowerCapital CostsPlant Operating CostsExternal CostsOther CostsElectricity MarketsComparing The Economics of Different Forms of Electricity GenerationEconomic Implications of Particular PlantsFuture Cost CompetitivenessMajor Studies on Future Cost CompetitivenessThe economics of nuclear power involves consideration of several aspects: 1. Capital costs, which include the cost of site preparation, construction, manufacture, commissioning and financing a nuclear power plant. Building a large-scale nuclear reactor takes thousands of workers, huge amounts of steel and concrete, thousands of components, and several systems to provide electricity, cooling, ventilation, information, control and communication. To compare different power generation technologies the capital costs must be expressed in terms of the generating capacity of the plant (for example as dollars per kilowatt). Capital costs may be calculated with the financing costs included or excluded. If financing costs are included then the capital costs change materially in relation to construction time of the plant and with the interest rate and/or mode of financing employed. 2.

These are the different uranium isotopes. Isotopes of uranium contain 92 protons in the atomcenter or nucleus. (The number of protons in the nucleus is what makes the atoms \\"uranium.\\") The U238 atoms contain 146 neutrons, the U235 atoms contain 143 neutrons, and the U234 atoms contain only 142 neutrons. The total number of protons plus neutrons gives the atomic mass of each isotope that is 238, 235, or 234, respectively. On an atomic level, the size and weight of these isotopes are slightly different. This implies that with the right equipment and under the right conditions, the isotopes can be separated.
