Small modular reactors (SMR s) are a class of small nuclear fission reactors, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations. The term SMR refers to the size, capacity and modular construction. Reactor type and the nuclear processes may vary.
The cost of raw uranium contributes about $0.0015/kWh to the cost of nuclear electricity, while in breeder reactors the uranium cost falls to $0.000015/kWh. [ 54 ] Nuclear plants require fissile fuel. Generally, the fuel used is uranium, although other materials may be used (See MOX fuel).
The technical specifications of the 4S reactor are unique in the nuclear industry. [2] The actual reactor would be located in a sealed, cylindrical vault 30 m (98 ft) underground, while the building above ground would be 22×16×11 m (72×52.5×36 ft) in size. This power plant is designed to provide 10 megawatts of electrical power with a 50 MW ...
Nuclear microreactor. A nuclear microreactor is a plug-and-play type of nuclear reactor which can be easily assembled and transported by road, rail or air. [1] Microreactors are 100 to 1,000 times smaller than conventional nuclear reactors, and range in capacity from 1 to 20 megawatts, compared to 20 to 300 megawatts for small modular reactors ...
Critical fission reactors are built for three primary purposes, which typically involve different engineering trade-offs to take advantage of either the heat or the neutrons produced by the fission chain reaction: power reactors are intended to produce heat for nuclear power, either as part of a generating station or a local power system such ...
The Chernobyl sarcophagus, built to contain the effects of the 1986 disaster. A nuclear reactor is a device used to initiate and control a fission nuclear chain reaction. Nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion. When a fissile nucleus like uranium-235 or plutonium-239 absorbs ...
The stable salt reactor (SSR) is a nuclear reactor design proposed by Moltex Energy. [115] 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.
Kilopower is an experimental U.S. project to make new nuclear reactors for space travel. [1][2] The project started in October 2015, led by NASA and the DoE ’s National Nuclear Security Administration (NNSA). [3] As of 2017, the Kilopower reactors were intended to come in four sizes, able to produce from one to ten kilowatts of electrical ...
