Much of their work culminated with the Molten-Salt Reactor Experiment (MSRE). MSRE was a 7.4 MW th test reactor simulating the neutronic "kernel" of a type of epithermal thorium molten salt breeder reactor called the liquid fluoride thorium reactor (LFTR). The large (expensive) breeding blanket of thorium salt was omitted in favor of neutron ...
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 ...
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 ...
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 ...
The electrically conductive molten sodium can be moved by electromagnetic pumps. [7] The fact that the sodium is not pressurized implies that a much thinner reactor vessel can be used (e.g. 2 cm thick). Combined with the much higher temperatures achieved in the reactor, this means that the reactor in shutdown mode can be passively cooled.
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 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 ]
