--- Ed > I think this is only a way to provide chemical heat by converting UH6 to U3O8.
I do not see how it could be chemical if the assertion that it will run 24/7 for *5 years* before refueling is true. If the U is natural, that much of it (with water as a moderator) would certainly go critical. Even if the U is depleted, or if there are poisons to keep it subcritical - that much of it in one place, for only chemical conversion - would be unimaginable .... Jones
