Traveling-wave reactors were first proposed in the 1950s and have been studied intermittently. The concept of a reactor that could breed its own fuel inside the reactor core was initially proposed and studied in 1958 by Savely Moiseevich Feinberg , who called it a "breed-and-burn" reactor. [ 1 ]
TerraPower is an American nuclear reactor design and development engineering company headquartered in Bellevue, Washington. TerraPower is developing a class of nuclear fast reactors termed traveling wave reactors (TWR). [1] TWR places a small core of enriched fuel in the center of a much larger mass of non-fissile material, in this case ...
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 version available in the future. [3] The 4S is a fast neutron sodium reactor
The Akademik Lomonosov, the world’s first floating nuclear power plant, sends energy to around 200,000 people on land using next-wave nuclear technology: small modular reactors. This technology ...
Nuclear reactors based on such designs "theoretically could run for a couple of hundred years" without refueling, says John Gilleland, manager of nuclear programs at Intellectual Ventures. Wave of the future: Unlike today’s reactors, a traveling-wave reactor requires very little enriched uranium, reducing the risk of weapons proliferation ...
The traveling wave reactor proposed in a patent by Intellectual Ventures is a fast breeder reactor designed to not need fuel reprocessing during the decades-long lifetime of the reactor. The breed-burn wave in the TWR design does not move from one end of the reactor to the other but gradually from the inside out.
The traveling wave reactor proposed by TerraPower is aimed to immediately "burn" the fuel that it breeds without requiring its removal from the reactor core and its further reprocessing. [ 45 ] The design of some SMR reactors is based on the thorium fuel cycle , which is considered by their promotors as a way to reduce the long-term waste ...
