​Olkiluoto 3 reactor pressure vessel and pressurizer steel fulfills all quality requirements

11.12.2015

​The Radiation and Nuclear Safety Authority, Finland (STUK) has accepted TVO's report on the steel quality of OL3 reactor pressure vessel. According to the report the steel quality of the pressure vessel, pressurizer and other primary circuit components meet all the quality requirements.

STUK's request for clarification was based on the reports of potential problems in the reactor pressure vessel material properties of Flamanville 3 reactor pressure vessel steel in France.

The steel forgings of OL3 reactor pressure vessel were manufactured by another process than the forgings of Flamanville's pressure vessel. Inspections carried out during the manufacturing process would have revealed any similar quality problems.
