Overview of Nuclear Processes and Safety Issues
As of 2011, nuclear safety considerations occur in a number of situations, including:
-
- Nuclear fission power used in nuclear power stations, and nuclear submarines and ships
- Nuclear weapons
- Fissionable fuels such as uranium and plutonium and their extraction, storage and use
- Radioactive materials used for medical, diagnostic, batteries for some space projects, and research purposes
- Nuclear waste, the radioactive waste residue of nuclear materials
- Nuclear fusion power, a technology under long-term development
- Unplanned entry of nuclear materials into the biosphere and food chain (living plants, animals and humans) if breathed or ingested.
With the exception of thermonuclear weapons and experimental fusion research, all safety issues specific to nuclear power stems from two issues - the toxicity and radioactivity of heavy fissionable materials, waste byproducts, and other radioactive materials, and the risks of unplanned or uncontrolled nuclear accidents.
Nuclear safety therefore covers at minimum: -
-
- Extraction, transportation, storage, processing, and disposal of fissionable materials
- Safety of nuclear power generators
- Control and safe management of nuclear weapons, nuclear material capable of use as a weapon, and other radioactive materials
- Safe handling, accountability and use in industrial, medical and research contexts
- Disposal of nuclear waste
- Limitations on exposure to radiation

Famous quotes containing the words nuclear, processes, safety and/or issues:
“The reduction of nuclear arsenals and the removal of the threat of worldwide nuclear destruction is a measure, in my judgment, of the power and strength of a great nation.”
—Jimmy Carter (James Earl Carter, Jr.)
“It has become a people’s war, and peoples of all sorts and races, of every degree of power and variety of fortune, are involved in its sweeping processes of change and settlement.”
—Woodrow Wilson (1856–1924)
“Love no man in good earnest, nor no further in sport
neither, than with safety of a pure blush thou mayst in
honor come off again.”
—William Shakespeare (1564–1616)
“To make life more bearable and pleasant for everybody, choose the issues that are significant enough to fight over, and ignore or use distraction for those you can let slide that day. Picking your battles will eliminate a number of conflicts, and yet will still leave you feeling in control.”
