Thorium MSR - Membership Levels

LFTRs are vastly more efficient than a uranium-fueled MSR, and they create very little waste. A thorium-fueled MSR reactor “burns” 99% of the thorium, but current uranium reactors consume just 1% of their fuel. That’s like burning a tiny part of a log while the rest gets contaminated with chemicals you must store for thousands of years.
