Terrestrial Energy’s reactor core is designed to be entirely replaced every seven years, in part to head off some of the problems earlier molten salt reactors experienced like corrosion.

For example, if a reactor in an MSR overheats, the liquid salt expands and naturally increases the leakage of neutrons from the reactor core, meaning they are no longer available to cause fission.

Funding from U.S. Department of Energy is intended to support efforts to develop and market Holtec reactors ...
