More detailed investigations concerning nuclear power plant product counterfeits to be continued

Press release

The Radiation and Nuclear Safety Authority STUK required in June 2016 that the Finnish nuclear power companies Fortum and Teollisuuden Voima (TVO) should investigate whether equipment of whose material quality one cannot be fully certain has been delivered to their nuclear power plants.

The reason for the request for investigations was the notification of the French company Areva according to which defects, neglects and counterfeits have been detected in the manufacturing and inspection documentation of parts of equipment delivered to nuclear power plants in France and possibly also other countries. 

Fortum and TVO have been investigating since last summer what types of equipment the suppliers under suspicion may have delivered to Finnish nuclear power plants.

For the running Olkiluoto 1 and 2 units, TVO issued specifications to STUK at the end of October. According to the specifications, no counterfeits were detected in the parts delivered to the running units and all inspected devices were compliant.

STUK received specifications concerning the Loviisa nuclear power plant from Fortum at the end of December. According to the specifications, inadequate or counterfeited documentation has not been found to this date, though investigations partly need to be continued, because they are difficult and time-consuming. Further information is expected by 31 March 2017.

TVO will also continue its investigations concerning Olkiluoto 3, which is under construction. The investigations focus on Le Creusot, a factory in France that has manufactured some of the equipment parts installed at OL3. The parts are part of the reactor’s primary circuit, so they are very important in view of safety.

Section Head Martti Vilpas from STUK points out that TVO has supervised the manufacture of the parts at the factory. STUK has also supervised their manufacture and testing and inspected the parts in connection with their installation. Therefore, Vilpas does not consider it likely that there could be any major problems in quality. “However, we must not leave room for even the slightest doubt, so TVO and the plant provider must investigate the matter thoroughly,” he says. Acceptable specifications are the precondition for obtaining an operation licence. STUK requires that more detailed investigations are completed by 30 April 2017.

STUK's request for investigation: OL3 - manufacturing of the main components of the primary circuit at the factory of Le Creusot (in Finnish)
