1) It is fueled by Thorium, which is plentiful, cheap and profiliation resistant, something which no nation will ever need to go to war over because it is everywhere!
2) It is a liquid fuel reactor, unlike current technology which uses solid fuel rods. this is it's greatest strength, it can use up all the fuel put in and produces almost no nuclear waste AND does not emit pollutants!
Because it uses liquid salts as the medium of choice, it can use very efficient power generators (Brayton cycle turbines) that is about 11%-12% more efficient than steam turbines.
Because of the above traits, the LFTR is inherently safe! It has no risk of dreaded nuclear meltdowns or massive steam explosions. In that light, the LFTR needs no safety clearance zone around it, and if that wasn't enough, the small size of the LFTR means it can be built underground.
