the splitting of atoms of a heavier element into lighter elements
the joining of two lighter atoms into a heavier element
nonrenewable fuel used in nuclear production.
Fission reactions occur as
particles called neutrons are released. The reactions are controlled when control rods are lowered between the fuel rods.
Fission reactions release heat which boils water which produces steam which drives a turbine which produces an electrical current
fissionable isotope used in nuclear energy production
converted into Plutonium in a breeder reactor making it fissionable
Coal V Uranium
COAL- causes 1/3 of air pollution in US. Emits sulfur dioxide which causes acid rain
URANIUM- produces little air pollution but extremely hazardous radioactive material. Costs less to produce than coal but the costs of building a safe nuclear reactor are very high
Low-level radioactive waste
wastes from nuclear power plants, research labs, hospitals, and industry
High-level radioactive waste
wastes from nuclear fission, cooling fluids found in a nuclear reactor (longer half life)
Radiation is released when the structure containing the uranium field melts, releasing radiation into surrounding environment
