U-235 is the world's primary nuclear fuel and is usually used in light water reactors. U-238/Pu-239 has found the most use in liquid sodium fast breeder reactors and CANDU Reactors. Th-232/U-233 is best suited to molten salt reactors (MSR). [12] Alvin M. Weinberg pioneered the use of the MSR at Oak Ridge National Laboratory. At ORNL, two ...
The 4S is a fast neutron sodium reactor. It uses neutron reflector panels around the perimeter to maintain neutron density. These reflector panels replace complicated control rods, yet keep the ability to shut down the nuclear reaction in case of an emergency. Additionally, the Toshiba 4S utilizes liquid sodium as a coolant, allowing the ...
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 ...
Enron has announced the “Enron Egg”, a micro-nuclear reactor that the newly reformed company claims can power homes for a decade. The only catch is that the parody company’s “revolution in ...
"Introducing the Enron Egg, the world's first micro-nuclear reactor for residential suburban use." The little device, according to Gaydos, has the ability to power a home for 10 continuous years.
Example of a molten-salt reactor scheme. A molten-salt reactor (MSR) is a class of nuclear fission reactor in which the primary nuclear reactor coolant and/or the fuel is a mixture of molten salt with a fissile material. Two research MSRs operated in the United States in the mid-20th century.
Rolls-Royce has been working on nuclear-microreactor technology for over three years, first collaborating with the UK Space Agency in 2021.
The BN-350 and U.S. EBR-II nuclear power plants were sodium cooled. EBR-I used a liquid metal alloy, NaK, for cooling. NaK is liquid at room temperature. Liquid metal cooling is also used in most fast neutron reactors including fast breeder reactors such as the Integral Fast Reactor. Many Generation IV reactors studied are liquid metal cooled:
