> when it's "just" faulty concrete or welding. In Finland during construction the local nuclear safety company found reinforced concrete that had 0 rebar in it etc forcing a lot of stuff to be redone due to someone trying to cut expenses. Though those issues happened a long time ago. The recent delays are mostly issues with the automation systems and the turbine (both subcontracted to Siemens by Areva). But yeah a lot of the issues are the "nobody has ever done this before". The steam turbine used by these plants is literally the largest ever built.
