Competent nuclear engineers and technicians have retired without being able to pass on their know-how, and cutting-edge nuclear-related industries have disappeared or been converted.

This same fear has been enough to fund SLS and Ariane programs. Basically to avoid the loss of a capability in case it's needed later on. For some reason it doesn't seem to apply to nuclear. And now people are complaining that building new reactors is expensive, arguably at least partially due to the supply chains no longer existing in the same scale as before.

If loss of expertise were the cause, then there would have been a cost minimum in the late 80s when the maximum number of engineers had 5-15 years of experience.

Instead costs rose for each new reactor (including repeat builds of each model).

This theory has no explanatory power over reality and predicts the opposite of what happened.

Should the delays and subsequent costs overruns then be simply attributed to increased regulatory complexity or corporate greed?

I'm looking at the list of reactors in France, most of the builds during the last millennium were completed in more or less 10 years. Then there was a gap, and the new one is taking way longer than previous ones.

Same thing has happened in many other countries. Including finland, where at first we got 4 reactors in 6-10 years, and then after a gap of 25 years the next reactor was a clusterfuck that took almost 20years to build.

Both of these reactors are of the same design, and the issues are at least partially attributed to the company having forgot how to manage such large projects due to the years long gap in construction.
