Safety problem found at Areva’s Finnish reactor before start-up – regulator. Finland’s nuclear regulator has identified a safety issue at Olkiluoto 3, a 1.6-gigawatt reactor built by France’s Areva, now renamed Orano, and the problem needs to be fixed before the unit can receive a permit to operate, the regulator told Reuters. The reactor is due to start producing electricity in January next year after a decade-long delay. Part of the pressuriser, a primary circuit component of the reactor, is vibrating at levels that exceed safety limits, said Pekka Valikangas, the regulator’s section head for nuclear reactor regulation, ahead of an important assessment which is due to be published on Monday. “The test results show that these vibrations are not approved,” Valikangas said in an interview.
