The delays of the extensive modernization work that took place at OKG’s plant last year resulted in a reduction of the electricity supply with approximately forty per cent compared to 2008. To mention one example, the work conducted in order to increase the safety as well as the capacity at Oskarshamn 3 caused a downtime of nine months instead of the planned three months. However, the measures taken create good conditions for future record high production levels.
In 2009 the total net electricity supply from OKG amounted to almost 8.5 TWh (billion kilowatt hours). This figure was distributed on circa 2.8 TWh for O1, 3.9 TWh for O2 and 1.7 TWh for O3. The energy availability amounted for O1 to 70.5 per cent, for O2 to 77.9 and for O3 to 15.2 per cent.
It is thus mainly the unforeseen extended downtime at O3 that has lead to a lower production level than the 15.1 TWh delivered in 2008. The original timetable for the modernization at O3 was on approximately three months, planned to start on August 2, 2008. However, delayed component deliveries meant that there was a risk of the downtime being extended over the winter, whereby the start of the installation work was postponed until March 1, 2009. The downtime has gradually been extended, due to for example additional work required in order to replace defected control rod shafts and attend to a turbine bearing in the newly installed turbine equipment.
- Unfortunately, the additional work resulted in the restart of O3 being postponed until December 17, says Managing Director Lars Thuring. Accordingly, we can not in full meet the expectations on maximum electricity deliveries during the current winter period, since the supply capacity during these first months after the restart is limited by a compulsory test run programme at varying power output levels. We are planning to deliver at full power in March, and by then we will also, with the new power capacity level of 1,450 MW, have the largest boiling water reactor in the world.
Other significant milestones in 2009 were that the low pressure turbines at O2 were replaced. This has resulted in a capacity increase of approximately 40 MW which in turn resulted in new records regarding the daily output at O2. In March 2009, the UN International Atomic Energy Agency, IAEA, established that OKG on international comparison has a great ability to run a nuclear operation. At the turn of the year the number of employees at OKG amounted to 969, an increase of six employees in 2009.
