It seems that the UK design review process has been extensive. 5 years, 27k manhours and $56M. Still, one has to wonder why a leader in nuclear tech would hire a foreign company to... oh, yeah, $ for the politicians and the rich men who pull their strings. EDF does have a lot of plants in France but I can't be arsed to look up their safety record. In any case, safety records are useless when yer playin catch with raw eggs.
