 EPA - Clean Energy - Electricity from Nuclear
Nuclear energy originates from the splitting of uranium atoms in a process called fission.
Although the nuclear reactor is radioactive, the water discharged from the power plant is not considered radioactive because it never comes in contact with radioactive materials.
Currently, the radioactive waste is stored at the nuclear plants at which it is generated, either in steel-lined, concrete vaults filled with water or in above-ground steel or steel-reinforced concrete containers with steel inner canisters.

Note: This is a side-excursion into the basics of nuclear energy, beyond the main scope of "from Stargazers to Starships." It is included because nuclear energy is important to modern society, and because section S-7 "The Energy of the Sun" has already provided many of the basic ideas.
The nuclear forces apparently prefer equal numbers of each kind, and light nuclei--helium, carbon, nitrogen, oxygen--usually maintain a 50:50 ratio, although nuclear variants ("isotopes") with small deviations from equality may exist and may be stable.
However, nuclear waste is still kept in temporary storage, as the national policy for its treatment and disposal continues to be debated.

 Nuclear Binding Energy
The binding energy curve is obtained by dividing the total nuclear binding energy by the number of nucleons.
The fact that there is a peak in the binding energy curve in the region of stability near iron means that either the breakup of heavier nuclei (fission) or the combining of lighter nuclei (fusion) will yield nuclei which are more tightly bound (less mass per nucleon).
The binding energies of nucleons are in the range of millions of electron volts compared to tens of eV for atomic electrons.

Nuclear power is used to power most military submarines and aircraft carriers and provides 7% of the world's energy and 15.7% of the world's electricity.
The use of nuclear power is controversial because of the problem of storing radioactive waste for indefinite periods, the potential for possibly severe radioactive contamination by accident or sabotage, and the possibility that its use in some countries could lead to the proliferation of nuclear weapons.
