Bill Gates is funding a company called Terrapower that is planning to bring compact MSR to market in the next 10 years. They already have working prototypes but are still a few years behind NuScale.
Wasn't Terrapower trying to develop a travelling wave reactor? Or is that a MSR design as well?
Terrapower is (was?) developing multiple technologies. They got approval for their traveling wave reactor (which uses molten sodium, not molten salt, but they are easily confused for obvious reasons) last week. Not sure if they're going to keep developing other techs.
