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."
The reactor will utilise a reactor pressure vessel made of 20MnMoNi55 steel [7] also known as “APURVA” (Advanced Purified Reactor Vessel Alloy). [4] BARC disclosed in January 2020 that a Core catcher design has been validated that can manage a 100% core melt accident.

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 fuel was 7 LiF-BeF 2-ZrF 4-UF 4 (65-29.1-5-0.9 mole %). The first fuel was 33% 235 U; later a smaller amount of 233 UF 4 was used. By 1960 a better understanding of fluoride salt based molten-salt reactors had emerged from earlier molten salt reactor research for the Aircraft Reactor Experiment.
[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 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
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.
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 prototype molten salt reactors were successfully designed, constructed and operated. These were the Aircraft Reactor Experiment in 1954 and Molten-Salt Reactor Experiment from 1965 to 1969 ...
