The reason you don't try to make bombs from power reactor plutonium: The long fuel cycle of power reactors produces too much Pu240 and Pu242. It's dang near impossible to get a nuclear explosion if there's much of those isotopes; their high spontaneous fission rate makes the bomb "fizzle" before the core can be sufficiently compressed.

Those who pretend to believe that industrial civilization can be run on "sunny days when the wind is blowing" energy are engaged in arithmetic denialism.
