The resulting waste from a thorium reactor is radioactive for dozens or hundreds of years not tens of thousands of years so you don’t need a giant Yucca Mountain style disposal site
That is assuming they don’t make significant amounts of Fe-60 (2.6 My half-life) by exposing steel pipes to neutron flux. While the fuel itself might have a shorter half-life, other waste still needs to be dealt with.
