That was the activation i was talking about. It is many orders of magnitude easier to deal with than fission waste (ie the hard part of nuclear waste). +sourabh bajirao
Thorium is not more common than Deuterium or the Lithium needed to bread Tritium. And lets not forget that Thorium is fertile not a fuel. You create 233U from it that is used as the fuel. It produces about the same waste as a normal Uranium fuel cycle with full reprocessing. There are however less Actinides that makes a bit easier... but then there is that pesky 234U, a strong gamma emitter than would make reprocessing very difficult.
Reprocessing adds about a factor of 60 to the usefulness of a pound of Uranium Note that you must
reprocess for a Th cycle since its not a fission fuel.
Finally the LFTR are totally safe/can't go wrong is really misleading. First nothing goes wrong as planed. Ever. Secondly its still a fission reactor with all the normal issues. ie decay heat. It can never just "turn off", cooling must be provided for quite some time. The salts used react with water and are corrosive. Core breaches are of course possible and just as bad as normal reactors (but better than that Russian rubbish). It is not
a panacea of nuclear energy.
Last but not least it would about about 10 years to build a full prototype and another 10-20 years of running before this would really be deployable in a wide scale.
Currently MSR reactors are not being developed.
