  Nuclear power - Wikipedia, the free encyclopedia
Nuclear power is the controlled use of nuclear reactions to release energy for work including propulsion, heat, and the generation of 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.
Nuclear power, coal, and wind power are currently the only realistic large scale energy sources that would be able to replace oil and natural gas after a peak in global oil and gas production has been reached (see peak oil).

In the U.S., a consortium of six major companies is planning construction of a new nuclear power plant, which would be the first since the 1970s.) [5], [6], [7] Almost all the advantages and disadvantages of commercial nuclear power are disputed in some degree by the advocates for and against nuclear power.
Disposal of spent fuel and other nuclear waste is claimed by some as an advantage of nuclear power, claiming that the waste is small in quantity compared to that generated by competing technologies, and the cost of disposal small compared to the value of the power produced.

 (S-8) Nuclear Energy
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.
Power reactors in the US use ordinary water as a moderator, inside a "pressure vessel" made of thick steel, with rod-like fuel elements and control rods fitted through openings in its lid.
The power level surged, the reactor vessel burst, and the hot steam and graphite (as well as combustible zirconium metal used in the fuel rods) reacted with hot steam and with oxygen of the atmosphere to produce an intense fire, whose plume rose to high altitudes and spread radioactive debris over a wide area.

 The Future of Nuclear Power
An interdisciplinary MIT faculty group decided to study the future of nuclear power because of a belief that this technology is an important option for the United States and the world to meet future energy needs without emitting carbon dioxide and other atmospheric pollutants.
But the prospects for nuclear energy as an option are limited, the report finds, by four unresolved problems: high relative costs; perceived adverse safety, environmental, and health effects; potential security risks stemming from proliferation; and unresolved challenges in long-term management of nuclear wastes.
The authors of the study emphasized that nuclear power is not the only non-carbon option and stated that they believe it should be pursued as a long term option along with other options such as the use of renewable energy sources, increased efficiency, and carbon sequestration..
