Nuclear power plants are base load stations, which work best when the power output is constant (although boiling water reactors can come down to half power at night). Their units range in power from about 40 MWe to over 1200 MWe. New units under construction in 2005 are typically in the range 600-1200 MWe. The largest nuclear reactors currently in operation are the Tokyo Electric Power Company's 1356 MWe advanced boiling water reactors at Kashiwazaki-Kariwa, Japan, built by Toshiba, Hitachi and General Electric.

Nuclear power plant accidents such as the explosion and fire in the Chernobyl Nuclear Power Plant[5] and radioactive waste[6] make nuclear power a controversial topic, enough so that the building of new commercial nuclear power plants has ceased—at least temporarily—in the U.S. and most of Western Europe.[citation needed] However, 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.

Main article: Nuclear reprocessing

Reprocessing of spent nuclear fuel can extend the usefulness of mined uranium. However, it is generally conceded that reprocessed fuel is more expensive than fuel from mined uranium (providing that adequate disposal space is available). Such processing of civilian fuel has long been employed in Europe (at the COGEMA La Hague site) and briefly at the West Valley Reprocessing Plant in the U.S. // Nuclear reprocessing separates any usable elements (e. ... The COGEMA La Hague site is a nuclear fuel reprocessing plant near La Hague on the French Cotentin Peninsula that currently has over half of the worlds light water reactor spent nuclear fuel reprocessing capacity. ... West Valley Reprocessing Plant is a spent nuclear fuel reprocessing plant at West Valley, New York, USA, was operated successfully from 1966-72. ...

Reprocessing of spent fuel to obtain plutonium for nuclear weapons has been done in a number of countries: however these programs are typically separate from civilian activities, and usually cloaked in secrecy.

Use of breeder reactors combined with reprocessing could extend the usefulness of mined uranium by more than 60 times. [1] However, breeder reactors, not yet well developed, are currently significantly more difficult to operate. A breeder reactor is a nuclear reactor that breeds fuel. ...

Accident indemnification

The Vienna Convention on Civil Liability for Nuclear Damage puts in place an international framework for nuclear liability [10]. However states with a majority of the world's nuclear power plants, including the U.S., Russia, China and Japan, are not party to international nuclear liability conventions.

Per the Energy policy of the United Kingdom through its Nuclear Installations Act of 1965, liability is governed for nuclear damage for which a UK nuclear licensee is responsible. The Act requires compensation to be paid for damage up to a limit of £150 million by the liable operator for ten years after the incident. Between ten and thirty years afterwards, the Government meets this obligation. The Government is also liable for additional limited cross-border liability (about £300 million) under international conventions (Paris Convention on Third Party Liability in the Field of Nuclear Energy and Brussels Convention supplementary to the Paris Convention). [11] Energy policy of the United Kingdom is a set of official publications and activities directed at the present and future production, transmission and use of various power technologies. ...
