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.
The stable salt reactor (SSR) is a nuclear reactor design proposed by Moltex Energy. [118] 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.
Russian nuclear microreactor Shelf-M. A nuclear microreactor is a 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 MWe (megawatts of electricity), compared to 20 to 300 MWe (megawatts of electricity) for small modular reactors (SMRs ...
According to the patent application [5] the reactor design has some notable characteristics, that sets it apart from other reactor designs. It uses uranium hydride (UH 3) "low-enriched" to 5% uranium-235—the remainder is uranium-238—as the nuclear fuel, rather than the usual metallic uranium or uranium dioxide that composes the fuel rods of contemporary light-water reactors.
A sample of thorium. Thorium-based nuclear power generation is fueled primarily by the nuclear fission of the isotope uranium-233 produced from the fertile element thorium.A thorium fuel cycle can offer several potential advantages over a uranium fuel cycle [Note 1] —including the much greater abundance of thorium found on Earth, superior physical and nuclear fuel properties, and reduced ...
Rolls-Royce has been working on so-called nuclear microreactors for more than three years. The company said the reactors could provide energy for data centers, mining, and space missions.
A single Rolls-Royce SMR power station will occupy the footprint of two football pitches and power approximately one million homes.
NuScale's SMR designs employ 9 feet (2.7 m) diameter by 65 feet (20 m) high reactor vessels that use conventional cooling methods and run on low enriched uranium fuel assemblies based on existing light water reactor designs. Each module is intended to be kept in an underground pool and is expected to produce about 77 megawatts of electricity.
