Apparently I need to explain . For a given reactor , it has to use fuel rods by the same maker , only that maker . In the thorium reactors , there are no fuel rods . After a reactor is made , that maker still makes profit off of said fuel rods . Also , thorium as comparably more common , roughly as common as lead . you want to get down to some numbers , ' scrustThere is roughly 3 x as much thorium in the earths crust than there is uranium . Also , thorium reactors while not perfect , obviously don ' t require a pressure shell like modern fast metal breeder reactors . well then why are we not using it if its betterThorium is a lot harder to weaponize . Let us not forget nuclear reactors were a nice side product of atomic weaponry being developed . Also i never said or implied there was no fuel , i said no fuel rods
