The same reason that France is utterly failing at building flamaville 3 - it's not a technical problem but of regulation, government and public support.
And yet, EDF successfully built Taishan 1 and Taishan 2 in China, pretty much in time and in budget. There were a couple of teething issues (as expected given these were the first two EPRs to enter service), but they are now running great.
According to Yves Bréchet [1], former head of the French Atomic Energy Commission, the main difference is not regulation, government or public support. It's something that should speak a lot to the engineers on HN, but is almost always absent in public debates: the lack of technical expertise. Think expert welders, pipe-fitters, boiler makers, etc. The expertise required when making a nuclear power plant is very high, including and especially when it comes to welding, quality of steel, etc.
Costly mistakes were made while welding critical parts of Flamanville 3 for instance, requiring expansive and expensive rework. I don't think Hinkley Point C is faring much better. On the other side of the world China has been building nuclear power plants relentlessly: they have all the expertise needed. If you allow me a slight exaggeration, given France and UK massive de-industrialization over the last few decades, we are now amateurs compared to China.
Again, it's not an issue of regulation. It's just that when you don't build things the know-how gets lost very very quickly. Something that should get hammered in the head of all CEOs/managers/decision maker...
Yves Bréchet point in the linked video is that it’s first and foremost technical expertise, rather than political/regulatory landscape that explains why Taishan has fared better than the other EPR projects.
It’s not something we (I’m European) want to hear.
It doesn’t mean that public support doesn’t impact projects in Europe (or democracies in general), but it should not be used as an excuse to refuse to look further.
For instance Flamanville got a massive delay because of welding issues. That’s not a regulatory or public opinion issue. That’s an issue with the (lack of) expertise of French welders.
I don’t remember if it is for this one, or for repairs in other French nuclear power plants, but Canadian welders were called to the rescue…
I think it was for other nuclear plants that had been operating. Foreign welders were needed because there was only so much welding one worker could do before they reached their radiation exposure limit.
