We set out to solve a problem the nuclear industry had set aside decades earlier.

Long before the market, our founders saw that advanced reactors were the future of nuclear.

Lead-bismuth reactors have powered submarines since the 1960s. But they had one challenge.

Our founders knew that if the corrosion problem could be solved, lead would be close to a perfect coolant.

We invented three steel alloys that forever changed the game for lead-cooling.

Now we are turning innovation into commercial units, together with the industries that will build them.
Our Mission
We are building the backbone of a growing world. Industries and societies need abundant energy to grow and to thrive. Clean baseload power - where and when it's needed.
