In reply to the discussion: Russia Unveils Detailed Plans To Build 21 New Nuclear Power Units By 2030 [View all]what I said is accurate
Not all actinides are nuclear fuels because the energy produced does not sustain a chain reaction. Thorium is an example though salting it with neutron producer (U233) can force it to produce a sustained reaction but on it's own, no.
Not all radio-isotopes of those actinides that are used as fuels are suitable for use in nuclear reactions because they cannot sustain a controllable chain reaction for example U235 is suitable as a fuel; U238 is not.
I think my case is proven.
Referring to your qualifications as a "scientist" I would think you would be aware that you could pile up 50 tonnes of U238 (you know the one with the symbol U atomic number 92 position 4 in the actinide series) and not have any sort of sustainable chain reaction.
