> Any nation state with access to U and graphite can simply construct a pile reactor to make Pu. Much easier to conceal and operate compared to trying to mask reactor operations at a civilian plant. The pile reactor that the US built during WW2 at the Hanford Site employed 45000 construction workers. Making plutonium is quite straightforward in theory, but practice tends to disagree with theory. Two nations that I know of decided that uranium bombs make more sense for them, South Africa and Iran. South Africa went on to build six such bombs.
