Notes

Containerised reactor designed for mass manufacturing on assembly lines in 40-foot shipping container format. Uses lithium, thorium, and low-enriched uranium fluoride salt as fuel with heavy water moderation. Two full-scale non-fission prototypes built and tested with water and FLiNaK salt. Third non-fission prototype planned. First nuclear test reactor planned at Paul Scherrer Institute in Switzerland in 2026 to 2027. Commercial deployment targeted for early 2030s. LCOE target of 20 dollars per MWh in mass manufacturing scenario. Company has accumulated more than 100000 hours of combined pump runtime across over 120 pumps tested.
