After being under repair for five months, one of Forsmark's nuclear reactors was supposed to start today. However, the owner Vattenfall announced yesterday evening that the start of Forsmark 3 will be postponed further, to the night of 1 February, according to a notice to the electricity exchange Nord Pool.
The reactor is now expected to reach full power on 3 February.
The prolonged shutdown, since 1 September 2024, has been due to crack formations in two of the plant's turbines.
