Discourse is FOSS and is fairly easy to host. I agree with sentiments that running right back to close source is probably not what the bulk of people here want. But then again most people use steam so I am a walking contradiction.

Scales directly with the amount of radiation present. Because the visual inspection happens in the water the radiation levels change a lot depending on where you are. Water is excellent as a radiation shield. I can’t remember the halving distance (thickness of material needed to halve the radiation levels) but an active fuel bundle only needing 6 feet to drop down to safe levels is an insane drop. Something on the order of 1000 Rad/hr or something coming off the bundles.

The used fuel bundles must remain under at least 6 feet of water or the whole refuel floor would start hearing their radiation badges beeping. The blue light only happens in water. In air you see nothing, I assume. By far away I mean in reactor which is like 60 or so feet underwater when the reactor cavity is flooded.

Your eyes would burn in radiation, but the static only occurs on cameras. I think high intensity particles can cause vision abnormalities, but I think our brain is good at hiding background noise pretty good. Filling in the gaps as it were. Or the mechanism of sight just isn’t as affected as the electronics in camera sensors. Not sure on the physics of that.

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.

Fun fact, the static generated by gamma radiation actually looks a lot like confetti with random pixels and streaks of pixels turning blue, yellow, red, green or a combination in true random fashion. I know this because I used to perform visual inspections on nuclear reactors.
