RETHINKING NUCLEAR

Seaborg is developing a nuclear power plant concept fundamentally different from what exists today.

We are making nuclear an inexpensive, sustainable and safe technology that can out-compete fossil fuels and revolutionise energy markets.

Our Compact Molten Salt Reactor, the CMSR, is safe, significantly smaller, better for the environment, and inexpensive even compared to fossil fuels.

By rethinking nuclear, we are working towards a future of abundant, affordable, low-emission energy available to all.

Our CMSR will be deployed on serially produced Power Barges that have an operational lifetime of 24 years .
The Power Barges are modular and can produce from 200 to 800 MW of electricity.

How is the CMSR different from conventional nuclear?

The core is key

Conventional nuclear reactors have solid fuel rods that need constant cooling, typically using water under high pressure.

In the CMSR, fuel is mixed in a liquid salt that acts as coolant. This ensures it can always be cooled and it cannot melt down or explode. It will simply shut down by itself in case of an emergency.

The importance of this is not only the safety but also a significant reduction in complexity and cost.
