Yes, but only from far away. The fuel bundles sort of glow like a blue light saber. Especially the “hot” ones right after we open the head of the reactor. I worked in various BWRs domestically and a few international. I spent many hours staring into the reactor glow from up on the refuel floor waiting for other work activities to finish up so I could do mine. It’s mesmerizing to look at but it gets real burning after like 3 days.
