Why doesn't the Candu sell better ?

It requires heavy water which is expensive. There are also many smaller pressurized water reactors giving wider applicability. CANDU reactors however are fairly flexible, including ability to use thorium and spent fuel from other reactors as fuel.

I believe what queenmandy meant by "liquid thorium" reactors was a completely different technology, using molten salt as a moderator. There are inherent safety factors of that design, but it has yet to be proven in a practical application. The only molten salt reactor ran for a few years in the 1960's and was shutdown. While there is a lot of theoretical promise to the design, that experimental reactor was not without problems including a large radioactive waste created.
