I guess I will never again espouse moderation in all things.

Fabulous watch, but I kept waiting for the Goodies to pop in.

Thanks for that, very interesting. There's also some good information on criticality accidents in a report from Los Alamos National Laboratory:

When the film was made in 1969, the UK was yet to have a criticality accident - they had one in 1970, though.

Interesting!
For anyone who wants a good read, somewhat related:
https://www.amazon.com/Manhattan-Project-Untold-Making-Atomic/dp/0595092381 (https://www.amazon.com/Manhattan-Project-Untold-Making-Atomic/dp/0595092381)
I have the first edition in hardcover. Was my father's actually. It would have to be since it was published before I was born. I've read that book multiple times, and have found it enjoyable each and every time. It's far better written than many of the "bomb" books that have come out relatively recently, so if you've read any of those and didn't like them, don't let that turn you off from checking this one out.

"Surely You're Joking, Mr. Feynman" (http://a.co/6IvGkjj) has a few interesting tidbits about criticality safety during the Manhattan project. In particular he tells one (possibly apocryphal) story about being sent to inspect an enrichment facility before it becomes operational, where he sees workers rehearsing the process by rolling around cartloads of mock canisters of partially enriched material. Alarmed, he turns to his guide and says "Why do you have that many canisters on one cart? Won't it explode*?!" To which his guide says, "Explode? Why on earth would it explode?" The whole thing was such a tightly-kept secret that no one had told the plant workers were told they were dealing with fissile material, let alone the possible dangers of criticality due to improper handling!
* I don't know if "explode" is Feynman's embellishment, his shorthand for something more accurate but less flamboyant, or my misremembering of the story, but I'm pretty sure that's the word he used in the book.

The Demon Core.
Another interesting read.

Another one.

This report is relatively damning, but is not as scathing as some other reports I have seen of the same incident.

google SL-1 nuclear reactor accident
In which criticality pinned a man to the ceiling.

On SL-1
" One of the shield plugs on top of the reactor vessel impaled the third man through his groin and exited his shoulder, pinning him to the ceiling."
"The bodies of all three were buried in lead-lined caskets sealed with concrete and placed in metal vaults with a concrete cover. Some highly radioactive body parts were buried in the Idaho desert as radioactive waste."
