Really enjoyed this post, I'll need to try to get a tour as well, hopefully within this decade.

If this sort of thing interests you, another interesting tour is the Hanford Site B Reactor tour: https://www.nps.gov/thingstodo/hanford-attend-a-b-reactor-to...

It's one third of the Manhattan Project National Historic Park, a few hours southeast of Seattle, with the other portions in New Mexico and Tennessee. I haven't been able to see the other portions, but walking into the main chamber of the B Reactor and looking up at it was an inspiring experience.
