Opponents believe that nuclear power poses many threats to people and the environment. These threats include the problems of processing, transport and storage of radioactive nuclear waste, the risk of nuclear weapons proliferation and terrorism, as well as health risks and environmental damage from uranium mining. They also contend that reactors themselves are enormously complex machines where many things can and do go wrong; and there have been serious nuclear accidents.
S. government military project to make enriched uranium and by building large production reactors to produce (breed) plutonium for use in the first nuclear weapons. The United States would test an atom bomb in July 1945 with the Trinity test, and eventually two such weapons were used in the atomic bombings of Hiroshima and Nagasaki.

Analysis of the economics of nuclear power must also take into account who bears the risks of future uncertainties. To date all operating nuclear power plants were developed by state-owned or regulated electric utility monopolies where many of the risks associated with construction costs, operating performance, fuel price, accident liability and other factors were borne by consumers rather than suppliers. In addition, because the potential liability from a nuclear accident is so great, the full cost of liability insurance is generally limited/capped by the government, which the U.

In 2016 the BN-800 sodium cooled fast reactor in Russia, began commercial electricity generation, while plans for a BN-1200 were initially conceived the future of the fast reactor program in Russia awaits the results from MBIR, an under construction multi-loop Generation IV research facility for testing the chemically more inert lead, lead-bismuth and gas coolants, it will similarly run on recycled MOX (mixed uranium and plutonium oxide) fuel.
International research is continuing into additional uses of process heat such as hydrogen production (in support of a hydrogen economy), for desalinating sea water, and for use in district heating systems. Industry
Following faça um link the 2011 Fukushima Daiichi nuclear disaster, costs are expected to increase for then-operating and new nuclear power plants, due to increased requirements for on-sitio spent fuel management and elevated design basis threats. Life cycle of nuclear fuel
Abaixo temos 1 exemplo por fusão nuclear em de que se fundem dois núcleos, 1 do deutfoirio e 1 do trítio, produzindo átomos do hélio:
No sistema secundário, a água aquecida pelo sistema primário transforma-se em vapor por água em 1 sistema chamado gerador por vapor. O vapor produzido pelo sistema secundário é aproveitado para movimentar a turbina de um gerador elé especialmentetrico.
Nuclear power plants are therefore typically run as much as possible to keep the cost of the generated electrical energy as low as possible, supplying mostly base-load electricity.
Essas condições sãeste atingidas, por exemplo, pelo interior dos núcleos das estrelas ou durante reações nucleares artificiais, tais como nos casos DE ogivas nucleares.
