Tim’s our expert on here...it would be interesting to hear his views on maintaining power supplies.
Now I'm out of the industry I wouldn't get anything other than the official line from the generators, ie "Everything's fine and we'll make sure the power stays on".
I don't believe nuclear safety would be at all compromised since so many of the systems are automated, can be remotely managed and rely on relatively low staffing levels anyway. Since most of the nukes share the same technology there would be plenty of scope for swapping people around and EDF runs a central management facility with a basement-level command centre that is able to be live connected to all the stations for managing issues, so they are extremely well-equipped to handle the nuclear side of things.
More vulnerable are the transmission and distribution networks, maintenance and repair of which require quite large numbers of workers. These I suspect would be harder hit by staff shortages possibly?
