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 ...
These would be scaled-down versions of the nuclear reactors that military submarines used at the time, utilizing uranium as the fissile material. Because the entire reactor would be replaced, Ford hypothesized that the owner would have multiple choices for reactors, such as a fuel-efficient model or a high-performance model, at each reactor change.
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.
The Victoria class are British-built diesel-electric fleet submarines designed in the late 1970s to supplement the Royal Navy's nuclear submarine force. They were decommissioned at the end of the Cold War. In 1998, Canada purchased the submarines to replace the aging Oberon-class submarines. Refit for Canadian service included the removal of ...
Illustration of a light water small modular nuclear reactor (SMR) The small modular reactor (SMR) is a class of small nuclear fission reactor, designed to be built in a factory, shipped to operational sites for installation and then used to power buildings or other commercial operations.
The Canada-class submarine was a proposed class of ten nuclear-powered attack submarines to be built for Canadian Forces Maritime Command (today's Royal Canadian Navy) with an option for two more. Announced in 1987, the class was intended to provide Maritime Command with a method for monitoring Canada's Arctic Ocean area while establishing ...
In carbon dioxide-cooled reactors such as the AGR, if the solid control rods fail to arrest the nuclear reaction, nitrogen gas can be injected into the primary coolant cycle. This is because nitrogen has a larger absorption cross-section for neutrons than carbon or oxygen ; hence, the core then becomes less reactive.
The nuclear fuel cycle employs a full actinide recycle with two major options: One is an intermediate-size (150–600 MWe) sodium-cooled reactor with uranium-plutonium-minor-actinide-zirconium metal alloy fuel, supported by a fuel cycle based on pyrometallurgical reprocessing in facilities integrated with the reactor. The second is a medium to ...
