OL1 power limitation due to condenser repair work
14.4.2014
A minor leak of seawater into the condenser has been detected at the Olkiluoto 1 plant unit. The leak is currently being located.
In the condenser, the steam that has been generated in the reactor and passed through the high and low pressure turbines turns back into water on the surface of seawater-cooled condenser pipes. The design of the condenser takes potential seawater leaks into consideration. Due to negative pressure, the direction of the leak is always towards the plant unit.
The repair work is estimated to take approximately eight hours. The work has no impact on nuclear safety.
