Temporary Operational Disturbance at Unit Oskarshamn 3

Pressrelease Thursday, December 15, 2016

On 15 December, the electricity delivery was temporarily stopped at unit Oskarshamn 3 (O3) due to an internal steam leak in the reactor building.

On Monday 12 December, a minor steam leak was detected in the reactor building at unit O3, within the set limit value. The leak has been monitored and after an analysis performed, a decision on measures required was made on 15 December, which entails that the production must be temporarily shut down.

Troubleshooting is currently in progress and the repair work is at present considered completed. The restart is scheduled for tomorrow evening on 16 December.
