Nuke plants to rely on PDP-11 code UNTIL 2050!

I know some of what is going on there too. They are replacing lots of stuff with modern things, designed to be as similar as possible to the originals, to resolve reliability issues, while avoiding severe difficulties with the safety case.

Certain non-nuclear equipment such as turbine monitoring is just going to be replicated using modern, reliable components. It is almsot entirely analogue, and they have wisely ruled out any new systems which contain software.

By the way, I think the CANDU is used only in Canada and India, which is unfortunate as it is actually a very good and potentially extgremely safe design, especially compared to the GE-Hitachi BWR, which despite all the alleged enhancements to the latest version is still something that I hope never to see in the UK. You don't fix something that is fundamentally wrong by bolting a few seemingly clever bits around the outside.
