The paying to train is one thing. The bigger problem is people who aren’t super experienced in these projects doing estimates and costings.

You’re always going to have some overruns, and if you’re lucky, some underruns too. But if your estimates are out of wack… well. Good luck. Combine that with Parkinson’s law and you are in for a world of hurt.

That’s the engineering knowledge lost over the last 30 years costed out.

Making 2 reactors since 95 has some side effects, a lot of the senior engineers since then have retired, standards have changed, and new engineers need to learn.
