The denatured molten-salt reactor (DMSR) was an Oak Ridge theoretical design that was never built. Engel et al. 1980 said the project "examined the conceptual feasibility of a molten-salt power reactor fueled with denatured uranium-235 (i.e. with low-enriched uranium) and operated with a minimum of chemical processing."
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 ...
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 Reactor (MSBR). The MSDR is a 750 MW th MSR design that uses LiF-BeF 2-ThF 4-UF 4 (71.5-16.0-12.0-0.5 mole %) as the primary fuel salt.
The reactor is proprietary molten salt reactor design that builds on two existing designs: the Denatured Molten Salt Reactor (DMSR) and Small Modular Advanced High Temperature Reactor (smAHRT). Both designs are from Oak Ridge National Laboratory. The key technology of the IMSR® is the integration of the primary reactor components, the ...

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 tetrafluoride. The ThorCon design is a floating power station to be built in a ...
FLiBe is a molten salt made from a mixture of lithium fluoride (LiF) and beryllium fluoride (BeF 2). It is both a nuclear reactor coolant and solvent for fertile or fissile material. It served both purposes in the Molten-Salt Reactor Experiment (MSRE) at the Oak Ridge National Laboratory .
The IMSR belongs to the denatured molten salt reactor (DMSR) [7] class of molten salt reactors (MSR). It is designed to have all the safety features associated with the Molten Salt class of reactors including low pressure operation (the reactor and primary coolant is operated near normal atmospheric pressure), the inability to lose primary ...
