It is a revolutionary technology that is descended from the Molten Salt Reactor (MSR) that was created in the 1950s during the dawn of the atomic age.
It is a nuclear reactor design that is completely different from the standard Light Water Reactor (LWR) that we are used to today.
Unlike LWRs, the LFTR is :
Clean and efficient - using nearly 100% of the nuclear fuel in it’s core, compared to just 2%-3% in normal LWRs. This means that it creates only about 0.08% of the nuclear waste and even that can be eventually recycled or safely handled.
Inherently Safe - The nature of the LFTR means it is unable to catastrophically fail (No nuclear meltdown, no massive steam explosions)
No nuclear profiliation - Unlike the LWR, it does not produce excess nuclear material that can be used to make nuclear weapons.
Small and low cost – Because it is so safe, there is no exclusion zone needed and a LFTR plant is small (2000ft²-3000ft², compared to 200,000ft² for LWR) and can be built underground.
