U232 is not fun to work with, well into the "robot arms" level of gamma radiation output. U235 and P239 are like "wear gloves, glovebox" In a lab, or WRT inevitable accidents and contamination, its like the difference between working with strong industrial acids vs nerve gases. Its really a huge pain. The article author seems to have hand waved away several practical engineering problems like this. Also see his interesting hand waving away of the steam cycle as we know it, hand wave away molten salt moderator issues, etc. Some things are a practical pain because nobody's given the engineers enough $$$ yet, some things are a pain because of basic physics and chemistry reasons. I think the article author is confusing those two. Certainly, the nuclear industry over the last 70 years has not lacked for money or brainpower.
