A fission fragment reactor is a nuclear reactor that generates electricity by decelerating an ion beam of fission byproducts instead of using nuclear reactions to generate heat. By doing so, it bypasses the Carnot cycle and can achieve efficiencies of up to 90% instead of 40–45% attainable by efficient turbine-driven thermal reactors.
This is a list of all the commercial nuclear reactors in the world, sorted by country, with operational status. The list only includes civilian nuclear power reactors used to generate electricity for a power grid. All commercial nuclear reactors use nuclear fission. As of December 2024, there are 419 operable power reactors in the world, with a ...
Hahn ultimately hoped to create a breeder reactor, using low-level isotopes to transform samples of thorium and uranium into fissile isotopes. [5] His homemade neutron source was often incorrectly referred to as a nuclear reactor, but it did emit measurable levels of radiation, likely exceeding 1,000 times normal background radiation.
Editor’s note: On Oct. 16, 2024, about 100 Tri-Cities area leaders and people who worked to preserve Hanford’s historic B Reactor as part of the Manhattan Project National Historical Park ...
The smaller reactors created by Kairos, a nuclear-energy startup, are different from the towers most people think of when they conjure up an image of a nuclear reactor.
The goal of small modular reactors is to create mini versions of larger nuclear fission generators at a lower cost and with more flexibility, Kairos CEO Mike Laufer told Yahoo Finance. But SMRs ...
The Lungmen Nuclear Power Plant under construction (now halted) This table lists stations under construction stations without any reactor in service. Planned connection column indicates the connection of the first reactor, not thus whole capacity.
NS Savannah was the first nuclear-powered merchant ship. She was built in the late 1950s at a cost of $46.9 million (including a $28.3 million nuclear reactor and fuel core) and launched on July 21, 1959.
