Spent-fuel recycling

Recycling America's spent nuclear fuel into next-generation reactor fuel.

Kalium Energy Technology is building America's domestic, proliferation-resistant nuclear fuel supply — using Pyrox, our patent-pending molten-salt process, to turn spent nuclear fuel into fuel for fast reactors.

America's nuclear build-out needs fuel it doesn't have

The U.S. aims to quadruple nuclear capacity to 400 GW by 2050, but next-generation reactors need fuel that today's supply chain can't provide — in 2024 the entire U.S. produced just 900 kg of HALEU.

The fuel already exists — as waste

More than 95,000 tons of spent nuclear fuel sit at 57 reactor sites with no permanent home. The uranium and transuranic actinides inside are exactly what fast reactors need.

Pyrox turns spent fuel into fast-reactor fuel

A single molten-salt process that recovers uranium and transuranics from commercial spent fuel as purified metal.

Proven, protected IP

ARPA-E funded, TRL-4 validated, patents filed.

Lower cost

One molten-salt step instead of many.

Built for real waste

Sized for the commercial oxide fuel stranded in the U.S. today.

Proliferation-resistant

Never separates pure plutonium.

How Pyrox works

Built on three decades of research

KET was founded by Dr. Michael Simpson, a University of Utah professor and former national lab researcher, to commercialize the Pyrox process developed in his lab.
