OKG Takes Measures to Handle Fuel Damage Before Winter Arrives

Pressrelease Friday, November 25, 2016

On the night before Sunday 27 November, the production will be temporarily shut down at unit Oskarshamn 3 (O3) in order to remedy minor fuel damage.

On 8 August, minor fuel damage was verified at unit O3 and it has been monitored since. When fuel damage finally develops and grows, there is a regulatory requirement in force stating that the operations must be immediately stopped in order to take the measures required.

– However, the fuel damage at unit O3 is still minor, but we choose to take the measures required at this time partly to not risk a shutdown in the middle of the cold winter when our large-scale and climate efficient electricity production is needed the most, says Mats Ekblad, production manager at unit O3.

All the 700 fuel assemblies in the unit O3 reactor will be lifted underwater to enable detection of the fuel damage by measuring the amount of free uranium in the water. During the works to be performed in the reactor hall, estimated to take 12 days to complete, the organisation will also take a great number of other measures which are not possible to perform during operation. Unit O3 is scheduled to resume operation on 9 December.

Unit Oskarshamn (O1) has a stable operation and produces electricity at maximum power.
