Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

I could see problems with striping of paint and destruction of electronics at those levels. Do we have reference levels for what "normal operation" levels were.

Well I can't see any anywhere, but You would think that normally they would need to be low enough for people to work round them, charging the reactor, swapping out fuel etc. and with radiation at that level, you wouldnt really want a pool of spent fuel around either, unless that is a level under the bowels of the machine where people dont go.  (although we do know theres at least one cable run underneath, and  the bit where we had people step in puddles so there has to be some form of access down below)

Do people work inside the containment, except for maintenance? Also worth to note: the drywell is not normally filled with water.

How does the radiation make the paint stripe?

This was reported from Chernobyl. My surmise is that at sufficiently high radiation levels the chemical structure of the paint is attacked and it is basically burnt or evaporated off the surface. Each element responds differently to various types of radiation. Some may vaporize, some may heat up to the point that the chemical bonds are broken and/or oxidized or reduced.

I had a friend who used to supply specialised paints to the nuke industry. I remember him saying that if you look old paint on a house it bubbles and cracks, in a normal working nuke plant, the paint on surfaces decays at five times the rate, depending on the  exposure. However everything is painted to keep moisture away from metal surfaces, as rust absorbs radiation more than plain steel, and is much harder to decontaminate. At vastly increased radioactive rates you'll get much more cracking and bubbling as impurities occur and you get  breakdown of some molecules in the paint matrix.

How does fire make the paint stripe?
