1. Nuclear Fact Sheet Matthew Pigott EGRS 352 Professor Nicodemus Process: Nuclear energy results from the splitting of uranium atoms in a process called fission. Fission releases energy to make steam to power a turbine that generates electricity. Types: Boiling Water Reactor- The same water loop serves as a moderator, coolant for the core, and steam source for the turbine. Pressurized Water Reactor- The water which flows through the reactor core is isolated from the turbine. Liquid-Metal Fast-Breeder Reactor- The fission reaction produces heat to run the turbine while at the same time breeding plutonium fuel for the reactor. Nuclear Energy & the Environment Emissions: Nuclear reactors produce neither air pollution nor carbon dioxide in operation. Wastes: Include uranium mill tailings, spent reactor fuel, and other radioactive wastes. Spent radioactive fuel is initially stored in specially designed pools or dry concrete or steel storage containers until sufficient radioactive half-life decay levels are reached. Land: To produce approx. 1,800 MW of nuclear power with two reactors, 1,100 acres of land is needed. World Statistics Electricity Supplied (GWh) Total Net Electrical Capacity (MW) Economics Costs: Costs of electricity are measured in cents per kWh. Capital costs – waste disposal an decommissioning of plants Fuel costs Insurance costs Operations and maintenance Nuclear vs. Other Energy Sources: Nuclear energy’s cost ranges from 104.40 to 115.30 in $/MWh On average nuclear energy is the eighth cheapest energy source Of the top eight, geothermal technology is the only source with a greater capacity factor than nuclear (92% vs. 90%) Nuclear Energy & the Community Safety: U.S. Nuclear Regulatory Commission regulates the handling, transportation, storage, and disposal of nuclear wastes. Large range surrounding nuclear power plants is restricted and guarded by armed security teams. U.S. reactors have containment vessels designed to withstand extreme weather events and earthquakes. Risk: The NRC uses Probabilistic Risk Assessment to evaluate overall nuclear energy risk. Risk is reduced by making an undesirable event less likely or by making its outcome less serious.
