POWERING A SUSTAINABLE EARTH - AND BEYOND.

A NEW GENERATION OF CLEAN NUCLEAR REACTORS.

a new generation of clean, safe nuclear power

We are developing inherently safe, proliferation-resistant molten salt BREEDER reactors that deliver Low-cost, zero-carbon energy, can desalinate water, provide industrial heat, and make life-saving medical isotopes, from a fuel supply that can last for millennia.

Fissionaire's reactors run at low pressure with passive safety: initially starting on LEU+ (low enriched uranium), then we make our own fuel by breeding fissile uranium from abundant thorium—Never again requiring enriched uranium.

90% of the World's power plants emit 2.2 million pounds of co₂ into our atmosphere every second—nuclear emits zero.

Bar chart showing carbon emissions by fuel type, with coal highest around 800, gas about 400, followed by biomass, solar, marine, hydro, wind, and nuclear much lower.

Nuclear supplies only 9-10% of the world's electricity—too little for a clean electrified future.

limited Uranium supply

Worldwide affordable uranium supply is limited to approximately 60 years with demand at least doubling by 2050—breeder reactors are a necessity, not an option.

Comparison of one ton of coal, uranium, and thorium cubes showing energy output and homes powered: coal 0.0022 GWh powers 1 home for 75 days, uranium 35 GWh powers 3,000 homes for a year, thorium 11,000 GWh powers 1,046,000 homes for a year.

Our reactor technology will turn abundant thorium, and naTural uranium into a millenia of power for the world.

scalable, deployable, repeatable

From Megawatt DEPLOYABLE microreactors and SMR’s for off-grid applications such as data centers and desalination plants, to GigaWatt scale power plants for the Grid.

Deployable design

Designed for cost-efficiency and reliable operation, our reactors will be manufactured in factories and transported worldwide by truck, rail, ship, or air.

clean energy

Our reactors will create clean energy to support global infrastructure. Affordable energy benefits all of humanity.

life-saving medical isotopes

Neutrons from our thermal spectrum Breeder reactors can generate significant amounts of medical isotopes such as Ac-225, & Mo-99. Each neutron can be considerably more valuable for medicine than for energy.

no scarcity

Fissionaire reactors not only generate abundant, affordable energy but also serve a unique secondary purpose-eliminating the scarcity of medical isotopes.

affordable treatments

Our reactor produces rare and valuable cancer-treating and diagnostic isotopes such as Ac-225, Mo-99, and many others—at volumes that could make modern cancer therapies as affordable as antibiotics.

desalination for agricultural & Drinking water

Fissionaire’s reactors are useful for more than just electricity. Paired with desalination systems, drinking water becomes abundantly available and drylands can be restored to grow food sustainably.

Agriculture

Output energy is used to turn salt water into freshwater. The result is an abundant supply of fresh water that can restore drylands and sustain agriculture worldwide, transforming water scarcity into a global resource.

Drinking water

Our Molten Salt Reactors provide the steady, heat, and power necessary for the most efficient desalination processes.

Industrial
Process Heat

Unmatched by any other clean energy, Fissionaire’s molten salt reactors can lead the way to Industrial decarbonization.

reduced carbon

Our Molten Salt Reactors generate high-temperature heat, reaching 650°C and eventually higher with advanced alloys. This reliable, intense heat can be used directly to replace the fossil fuels used in energy-intensive industrial processes.

increased potential

TS-MSBRs benefit energy intensive industrial processes such as manufacturing steel, cement, and chemicals like fertilizer—ultimately affecting the quality and price of essential global products.
