One of the advantages of China's large and diverse reactor programme is that when they are building FOAK designs and something comes up that holds up the work (as it did on both their AP1000 and their EPR builds), they put their nuclear qualified workforce on buses and move them to other builds.

Compare that to Flamanville, Olkiluoto, and the US AP1000 builds where every time there was a work stoppage to review a detailed design element, a massive and expensive workforce just had some paid chill time.
