I think they do actually have highly enriched uranium at the MIT reactor. As in weapons grade. The little info I could find on it stated 93% enriched, which is pretty darn high.

Also, if you want to get a tour of the MIT fusion lab, better try hard this year. It's unclear whether it is going to enough funding to continue.
