Transatomic Power

Transatomic Power's innovative nuclear reactors turn nuclear waste into a safe, clean, and scalable source of electricity.

Power from nuclear waste 
Our reactor can convert the high-level nuclear waste produced by conventional nuclear reactors each year into $7.1 trillion of electricity. At full deployment, our reactors can use existing stockpiles of nuclear waste to satisfy the world’s electricity needs through 2073. 

Greatly reduced radioactivity 
Conventional reactor waste is radioactive for hundreds of thousands of years. Our reactor reduces the majority of the waste's radioactive lifetime to hundreds of years, thereby decreasing the need for permanent repositories such as Yucca Mountain. 

Inherently Safe 
Unlike conventional reactors, which must rely on operator action, external electric power and active safety systems to prevent damage in accident scenarios, the physics of our design ensures our reactor is always passively safe. 

Efficient modular design 
Our compact 200 MWe molten salt reactor can be manufactured economically at a central location and transported by rail to the reactor site. Utilities can use the profits from the first reactor installed to fund construction of additional units.
