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.
The Molten-Salt Reactor Experiment (MSRE) was an experimental molten-salt reactor research reactor at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. This technology was researched through the 1960s, the reactor was constructed by 1964, it went critical in 1965, and was operated until 1969. [ 1 ]
Molten salts (fluoride, chloride, and nitrate) can be used as heat transfer fluids as well as for thermal storage. This thermal storage is used in concentrated solar power plants. [8] [9] Molten-salt reactors are a type of nuclear reactor that uses molten salt(s) as a coolant or as a solvent in which the fissile material is dissolved ...
The U.S. Nuclear Regulatory Commission is issuing a construction permit for a new type of nuclear reactor that uses molten salt to cool the reactor core. The NRC is issuing the permit to Kairos ...
The integral molten salt reactor (IMSR) is a nuclear power plant design targeted at developing a commercial product for the small modular reactor (SMR) market. It employs molten salt reactor technology which is being developed by the Canadian company Terrestrial Energy. [1] The IMSR is based closely on the denatured molten salt reactor (DMSR ...
The Molten-Salt Demonstration Reactor (MSDR) was a semi-commercial-scale experimental molten salt reactor (MSR) design developed at Oak Ridge National Laboratory (ORNL). [ 1 ] Due to the success of both the Aircraft Reactor Experiment (ARE) and Molten Salt Reactor Experiment (MSRE), ORNL went on to design a MSDR and a Molten Salt Breeder ...
The power station would contain two 250 MWe small modular reactors. The replaceable reactors are to be removed and replaced every four years. As molten salt reactors, they are designed for the use of fuel in liquid form, which also serves as primary coolant. [4] The fuel would be about 20% enriched uranium tetrafluoride and thorium ...
The SSR design being developed by Moltex Energy Canada Inc. is the Stable Salt Reactor - Wasteburner (SSR-W), which incorporates elements of the molten salt reactor, and aims to have improved safety characteristics (intrinsically safe) and economics (LCOE of $45/MWh USD or less) over traditional light water reactors.
