They worked around the CfD and shifted nearly 2 billion of the costs to the next nuclear build by paying the first project out of the new budget for "lessons learned"!

Apparently the main lesson learned was, don't use a CfD because you'll be contractually bound to your initial bid and be responsible for cost overruns. Instead consumers are paying upfront for construction, with no cap on costs for the next one.

Though of course that's not really a lesson learned. Their CFO knew enough at the time the deal was originally signed to resign over it.

One crucial point is that military nuclear know-how (engines and weapons) needs a civilian industry for continuity of knowledge and betterment of practices and procedures.

I'm not sure how essential Hinckley Point C would be in this regard (probably not really), but I don't think this is about nuclear fuel.
