Company Profile

Terrestrial Energy USA is competing in the DOE Reactor Pilot Program with Project TETRA, based on their Integral Molten Salt Reactor (IMSR) design. The IMSR dissolves low-enriched uranium directly into fluoride salt, which serves simultaneously as fuel and coolant — a fundamentally different approach to reactor physics than conventional solid-fuel designs. The reactor operates at high temperature with low pressure, enabling high-efficiency electricity generation and industrial heat applications. Terrestrial Energy is also pursuing a separate NRC licensing track in the US and has an active commercial pipeline in Canada. The fluoride salt design requires no HALEU — a key supply chain advantage.

Reactor Specs

REACTOR DESIGN

Project TETRA · Molten Salt Reactor

Uses molten fluoride salt as coolant instead of water. Operates at higher temperature for greater thermal efficiency.

POWER OUTPUT

195 MWe

Powers ~158,535 average US homes. A standard large nuclear plant produces ~1,000 MWe.

COOLANT

Fluoride Salt

Very high boiling point means low operating pressure. Chemically stable. Salt solidifies if leaked — passive containment.

FUEL TYPE

Low-enriched UO₂ (dissolved in salt)

Standard uranium dioxide ceramic pellets. Used in virtually every operating commercial reactor. Well-understood supply chain.

TARGET OPERATION

2026

US nuclear projects historically require 7–10 years from construction permit to first power. The 2026 target assumes factory-built modular components and no major regulatory delays.

SITE LOCATION

TBD

Site not yet selected. Selection typically occurs 2–3 years before license application, driven by grid capacity, water access, and state regulatory climate.
