the necessities
The Necessities
  • Self regulating when it is ON
  • Passively safe when it is OFF
  • Inherently safe in case of an ACCIDENT

fuel for a lifetime
Fuel for a lifetime?

You consume a ball of coal 10 meters in diameter…

…or a ball or thorium 37mm in diameter.

An Efficient Design

Little or no radioactive waste

No bomb materials

Low cost per power delivered

A small physical size

A wide choice of building sites.

size matters
Size matters!

Your nuclear waste is the size of a few grains of rice!

Lets Make Power
  • The heat transfer fluid (molten salt) is at low pressure.
  • We can use a gas cycle, like a jet engine, at high temperature.
    • This means they can have high efficiency, a 50% reduction in power rejected to the environment per power delivered to the electric grid.
  • These plants can run at partial load.
