Finland’s regulator approves restart Olkiluoto-2

Finland’s nuclear regulator Stuk has given permission for the Olkiluoto-2 nuclear power plant to be restarted following an incident last week caused by a fault in the purification system for the reactor cooling water, operator Teollisuuden Voima Oyj (TVO) said.

The 890-MW boiling water reactor unit, which began commercial operation in 1982, was disconnected from the national grid due to the incident on 10 December at 12:22 local time. Immediate actions required to prevent the recurrence of the event have been implemented, TVO said.

The company said it had submitted its restart application to Stuk on 14 December.
