The world needs
At Moltex, we are developing nuclear reactor technologies that deliver clean energy at a lower cost than coal or gas.
Moltex Energy Limited has two subsidiaries: Moltex Energy Canada Inc. and MoltexFLEX Limited.
Moltex Energy Canada Inc., and its subsidiary Moltex Energy USA LLC, are developing the Stable Salt Reactor-Wasteburner (SSR-W), a reactor that uses recycled nuclear waste as fuel, and the WAste To Stable Salt (WATSS) process for recycling spent fuel. The company is headquartered in Saint John, New Brunswick, and focused on delivering first-of-a-kind units for NB Power.
MoltexFLEX Limited is developing the FLEX reactor. This uranium-fueled, thermal spectrum reactor provides flexible and dispatchable energy from low-impact sites. The company, including its new, molten salt laboratory, is based in Warrington, UK.
The Stable Salt Reactor – Wasteburner (SSR-W) is a fast reactor that uses recycled nuclear waste as fuel. In locations with existing inventory of nuclear waste, the SSR-W offers a cost-effective, environmentally friendly, and socially acceptable solution to waste minimization.
WAste To Stable Salt (WATSS) is a process in which nuclear waste is recycled to produce fuel suitable for an SSR-W or other fast reactor.
The FLEX reactor is a uranium-fueled, thermal spectrum reactor which generates heat at higher temperatures. The heat is ideal for numerous applications, including electricity generation, hydrogen production, industrial and district heating, marine propulsion and water desalination.
GridReserve is a series of tanks used to store thermal energy from the SSR-W or FLEX reactor and dispatch it to the grid when needed. With GridReserve, the reactors can answer spikes in energy demand, complementing intermittent renewables.
Fuel and coolant are combined, and pumped between the reaction chamber and heat exchanger in a complex circuit.
The circuit components – which include many moving parts and thousands of welds – must withstand this hot, corrosive and radioactive salt mixture, presenting a huge technical challenge.
Fuel and coolant are separate, so the radioactive fuel touches nothing except its own containment tube.
This elegant and simple idea was set aside 70 years ago, but modern computing tools have shown it will work. Separation allows sacrificial metals to be added to the salts to prevent corrosion.
