The basic principles of Stable Salt Reactor (SSR) technology are simple.
Heat is generated when nuclear fission takes place in tubes filled with molten salt fuel. This heat is then transferred to a primary salt coolant, where it circulates through heat exchangers and passes to a secondary salt coolant which sends the heat to storage tanks. The heat can be used to produce electricity, hydrogen, or in other industrial processes.

Stable Salt Reactor variants
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. Moltex intends to build an SSR-W in Saint John, Canada.
The Stable Salt Reactor – Uranium (SSR-U) is a uranium-fueled, thermal spectrum reactor which generates heat at higher temperatures. As well as generating electricity, this heat is ideal to produce clean, low-cost hydrogen, which will play a crucial role in the decarbonization of hard to reach areas of the economy such as heavy industry, heating and transportation.
The Stable Salt Reactor – Thorium (SSR-Th) will use thorium, which is three times more abundant than uranium, and is a current byproduct of rare earth mining. There is almost certainly enough thorium to meet the world’s energy needs for several tens of thousands of years.
SSR technology is uniquely positioned to deliver clean, low-cost energy, addressing climate change, reducing energy poverty and spurring economic development.
