![]() Each kWh of nuclear electricity requires 0.1-0.3 kWh of life cycle energy inputs.16 Typical reactors hold 18 million pellets. height and diameter) contains the energy equivalent of one ton of coal or 149 gallons of oil. Uranium is mostly extracted by in-situ leaching (ISL) (58.3%), open pit mining (18.7%), and underground mining (16.1%).plants currently use “once-through” fuel cycles with no reprocessing. Powering a one-gigawatt nuclear plant for a year can require mining 20,000-400,000 t of ore, processing it into 27.6 mt of uranium fuel, and disposing of 27.6 t of highly radioactive spent fuel, of which 90% (by volume) is low-level waste, 7% is intermediate-level waste, and 3% is high-level waste.12,13 U.S. ![]() The nuclear fuel cycle is the entire process of producing, using, and disposing of uranium fuel. nuclear plants have typically been 2 to 3 times higher than original estimates. Estimated LCOE for new nuclear plants built in the near future are about two times higher than estimates for wind and about three times higher than solar.Estimated LCOE for plants built in the near future are: combined cycle natural gas: 4.27 ¢/kWh advanced nuclear: 7.10 ¢/kWh and biomass: 7.72 ¢/kWh. Levelized cost of energy (LCOE) includes the lifetime costs of building, operating, maintaining, and fueling a power plant.Countries generating the next largest amounts of electricity using nuclear were China, France, and Russia. generated nearly a third of the world’s nuclear electricity. 3,4 As of May 2023, 59 reactors were under construction, including 1 in the U.S. 667 reactors have been built worldwide since the first was built in 1954 in Obninsk, Russia, though currently, there are only 436 in operation, 93 of which are in the U.S.2 During the 1970s, more than 50 nuclear reactors went online.1 Presently, 28 states have at least one nuclear plant and 32 plants have two or more reactors. nuclear power plant began commercial operations in 1958. Nuclear power plants had a capacity factor of 92.6% in 2022. electricity, and this share has remained stable since around 1990. Nuclear energy provides about 19% of U.S.and other nations search for low-emission energy sources, the benefits of nuclear power must be weighed against the operational risks and the challenges of storing spent nuclear fuel and radioactive waste. Nuclear is often labeled a “clean” energy source because no greenhouse gases (GHGs) or other air emissions are released from the power plant. Nuclear power plants generate electricity by using controlled nuclear fission chain reactions (i.e., splitting atoms) to heat water and produce steam to power turbines.
