Molten Salt Solutions raises $7m seed for pilot isotope production

Lithium isotope enrichment technology for the fuel needs of advanced fission and fusion reactors.

Updated Oct 16, 2026By RoundOS Funding desk

The financing will accelerate pilot-scale production and strengthen domestic supply of enriched lithium isotopes for advanced nuclear systems.

Lithium-6 is needed for fusion applications, while lithium-7 serves advanced molten-salt fission reactors. Moving production toward pilot scale connects the company’s separation technology with those reactor supply needs.
