    Ars Technica[^]:

    The US is still regulating some enriched uranium based on an analysis from the 1950s.

    And hopefully not *be* one

      Really, really old sci-fi book "When Worlds Collide" I believe had atomic rockets in it. Yep I found them When Worlds Collide - Wikipedia[^] and After Worlds Collide - Wikipedia[^] Now try to find them in a library.

      I’ve given up trying to be calm. However, I am open to feeling slightly less agitated. I’m begging you for the benefit of everyone, don’t be STUPID.

          Regarding the usability of not highly enriched uranium, there is a paywalled article in the current edition of Science: https://www.science.org/doi/10.1126/science.ado8693[^] It tells us that uranium enriched to more than 10% U-235 can be used to build a bomb, but you may need a ton of it. On the other hand, when such 10-20% enriched uranium is used - and thus produced - for commercial purposes, the currently clear line of distinction of "weapon uranium" and "civil uranium" gets blurred, and non-proliferation checks fail.
