Finnish EPR reactor faces new challenges. A valve leak has been discovered on the Finnish nuclear reactor Olkiluoto-3, built by a consortium formed by Areva and Siemens, the Finnish regulatory authority STUK announced on Monday. This third generation EPR reactor, which has accumulated more than ten years of delays since the launch of the site in 2005, should start producing electricity from November.

Finland’s long-delayed Olkiluoto 3 (OL3) nuclear reactor was hit by another setback after the nation’s safety watchdog reported valve problems in a component involved in the cooling process. The reactor in western Finland was built by a consortium of France’s Areva and Germany’s Siemens and had been due to start producing electricity in November this year. “A leak was observed in the mechanical control valve of one of the pressuriser safety valves,” nuclear watchdog STUK said in a statement on Monday, adding that a full investigation is required before it can issue a nuclear fuel loading permit. “This is very serious,” STUK’s head of inspection, Iiro Paajanen, told Reuters, adding that the leak was in part of the reactor’s primary circuit and involved in its cooling. However, Areva said the issue is unlikely to cause further delay for the reactor, which was originally due to be completed in 2009.
