Since the topic is second hand nuke stories, here are mine. Told to me by an undergrad who worked in the British nuclear industry for a while.
It seems the British cut more than a few corners in the early days of their nuclear program. This guy had an intern job at one of the sites that was being cleaned up. His job was to do work in one of the contaminated rooms. He loved the job because he only worked 2.5 minutes per day. That was the max time allowed in the room. Run in, do a bit of work, run out.
Deep under the facility were huge sewer tunnels that lead to the ocean. He and another guy were exploring one for some reason I don't recall. Walking along, the came upon a pile of debris. Their radiation counters went nuts. They swiftly turned around and left the tunnels. Seems someone found a convenient way to dispose of spent fuel rods: dump 'em down a shaft. 30 years later, this guy finds them.
