Very cool place - you can go through almost the entire plant and get a really good idea about how it worked. There are also a couple of test beds for nuclear-powered aircraft engines (?!).

I took an unplanned turn off the main highway to give this a look. It was a free tour, and quite informative. A lot of history, but some science as well. I do think Science, engineering and Tech savvy people will enjoy it, but I...More

This is a wonderful place to see how real engineers did it. There are guided tours as well as a brochure for self-guided exploration. Explanations are clear, and the various pieces of equipment are clearly labeled. It's a must-do for anyone with an interest in...More

This place is amazing. You can self-tour (or do it guided) the actual EBR-1 reactor building, a lot of it still intact - amazing they could do this without having to decommission the site. See the original control room and press buttons. See the reactor...More
