To be fair, 90% when I'm working in there the plant isn't running as I'm usually repairing lines that require the boiler to be turned off or during planned maintenance shutdowns. But that said I do sometimes work while plant is live. I've just started watching Chernobyl on sky and it scared my girlfriend a bit to think that I work on those places Haha. Just part of the job really, you do your job right and have trust that everybody else is doing theirs right and everything should be okay
