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.
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), a reactor design from Oak Ridge National Laboratory. In addition, it incorporates some elements found in the small modular advanced high temperature reactor ...
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 coolant salt in the SSR-W reactor tank is a chloride-based coolant salt. The coolant also contains an agent to reduce its redox potential, making it virtually non-corrosive to standard types of steel. The reactor tank, support structures and heat exchangers can therefore be built with standard 316L stainless steel.
The company is developing a 195 MWe Integral Molten Salt Reactor (IMSR) design [2] and completed its Pre-Licensing Vendor Design Review [3] in 2023 with the Canadian Nuclear Safety Commission. [4] The IMSR uses molten salt reactor technology and is one example of a small modular reactor (SMR) characteristic of Generation IV nuclear reactor designs.
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 ...
MoltexFLEX is a British nuclear energy company developing small modular molten salt reactors.Their reactor designs, termed "FLEX reactors", are stable salt reactors, and feature a hybrid approach whereby fuel assemblies similar to current light water reactors containing the liquid salt fuel mixture are submerged in a pool of liquid salt coolant.
Natura Resources, LLC is one of the nation's leaders in the deployment of small, modular nuclear reactors with the deployment of its Gen. IV Molten Salt Reactor (MSR-1) system.
