The stable salt reactor (SSR) is a nuclear reactor design proposed by Moltex Energy. [117] It represents a breakthrough in molten salt reactor technology, with the potential to make nuclear power safer, cheaper and cleaner. The modular nature of the design, including reactor core and non-nuclear buildings, allows rapid deployment on a large scale.
Economic factors of scale mean that nuclear reactors tend to be large, to such an extent that size itself becomes a limiting factor. The 1986 Chernobyl disaster and the 2011 Fukushima nuclear disaster caused a major set-back for the nuclear industry, with worldwide suspension of development, cutting down of funding, and closure of reactor plants.
In commercial nuclear power plants carbon dioxide has usually been used, for example in current British AGR nuclear power plants and formerly in a number of first generation British, French, Italian, and Japanese plants. Nitrogen [44] and helium have also been used, helium being considered particularly suitable for high temperature designs. Use ...
Hanford’s historic B Reactor, the world’s first full-scale nuclear reactor, went critical on Sept. 26, 1944. Wigner’s team had designed the Hanford reactors to house 1,600 process tubes.
Nuclear microreactors, a subcategory of Small Modular Reactors (SMRs), are a developing type of nuclear power plant that is designed to generate electricity on a smaller scale than traditional nuclear reactors.
This table lists all currently operational power stations. Some of these may have reactors under construction, but only current net capacity is listed. Capacity of permanently shut-down reactors is not included, but capacity of long-term shut-down reactors (today mainly in Japan) is included.
NuScale Power and Oklo specialize in the development of small modular nuclear reactors, designed to produce a fraction of the power output of a traditional 1 gigawatt-plus nuclear power plant.
The Generation IV International Forum (GIF) is an international organization with its stated goal being "the development of concepts for one or more Generation IV systems that can be licensed, constructed, and operated in a manner that will provide a competitively priced and reliable supply of energy ... while satisfactorily addressing nuclear safety, waste, proliferation and public perception ...
