As someone on Reddit pointed out, this was not weapons-grade uranium (~80%+ enriched). This uranium was 3-5% enriched, and they only had a few pounds of it (you'd need at least ~55lbs for a small nuclear bomb).

It's not even a reactor as I understand it--it's basically just a sealed neutron source and couldn't go critical.

It's not terribly surprising that they'd have something like that though. Kodak's Rochester plant was basically the chemical version of Hanford Site--lots of government work, little public oversight. My grandfather and several uncles worked there, and all received comprehensive life insurance as a standard benefit.
