Molten salt is salt which is solid at standard temperature and pressure but liquified due to elevated temperature. A salt that is liquid even at standard temperature and pressure is usually called a room-temperature ionic liquid, and molten salts are technically a class of ionic liquids.

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.

May 1, 2022 · The molten salt cooled reactor is an advanced nuclear reactor concept that utilizes molten salt as either a coolant for solid fuel or as a fuel salt. The liquid phase provides orders of magnitude higher heat capacity per cubic meter than the gas phase.

Feb 26, 2007 · The term "Molten Salt" is self-descriptive; it is melted salt(s). Another common name is Fused Salt (s). The simplest example of a molten salt would be to heat sodium chloride ("table salt") to a red heat (greater than 801° C, or 1474° F) 1 …

Oct 15, 2024 · To achieve this objective, the paper analyzes four types of molten salts—nitrates, chlorides, fluorides, and carbonates—by examining their properties and applications relevant to the chemical industry.

This report provides an update on the molten salt reactor thermophysical properties database that is being developed as part of the U.S. Department of Energy Advanced Reactor Technology Program Molten Salt Reactor (MSR) campaign. A summary of recent MSR-relevant literature and a discussion of data gaps are provided.

Molten salts are a novel heat transfer system whose potential is just beginning to be realised. They’re safe, stable, and efficient for higher-temperature systems. Molten salts are also better for the environment and pose few health hazards. In this article, you will learn about:

Supported by Office of Naval Research (ONR), this paper presents a survey of molten salt properties used in solar power storage, as well as the history of molten salt usage for energy storage and production.

Jun 29, 2020 · Molten salt reactors are nuclear's future, but there's still a lot we don't know. A new breakthrough could help engineers crack the next phase of nuclear energy.

The inspiration is the work the United States' Oak Ridge National Laboratory (ORNL) did by building and operating 2 successful Molten Salt Reactors (Nuclear Reactors) in 1954 (the ARE) and the 1960s (the MSRE). The drawing to the right is from " ORNL-4812: The Development Status of MOLTEN SALT BREEDER REACTORS" (1972).
