A new malfunction could weaken the EPR nuclear reactors a little more, already discredited by delays, poor workmanship and additional costs in series. The failure of a pressurizer safety valve, critical equipment for nuclear reactor safety, occurred during a test on the EPR reactor in Finland last March. Problem: the defective part is also present in the EPR under construction in Flamanville (France) and in the two EPRs already put into service in Taishan (China). Could this new glitch cause another delay in the Norman EPR, who is already more than ten years behind schedule and an additional cost of 9 billion euros? The Finnish nuclear safety authority (STUK) has just informed the various nuclear safety authorities in charge of EPRs around the world of the anomaly.
