What are Molten Salt Reactors?

A molten salt reactor (MSR) is any nuclear reactor that employs liquid halide salt to perform a significant function in-core.  MSRs include a broad spectrum of design options including:

• ​liquid- and solid-fueled variants,
• chloride- and fl​uoride-based fuel salts,
• thermal, fast, time variant, and spatially varying neutron spectra,
• wide range of reactor power scales,
• intensive, minimal, or inherent fuel processing,
• multiple different primary system configurations, and compatibility with
• nearly all fuel cycles.
