Production Information
The production display on our homepage shows the production at Oskarshamn 3 (O3) in real time, meaning it is updated continuously every minute, around the clock. Any additional information about our operations can be found below, as well as via the Nordic electricity exchange market nordpoolgroup.com.
Production Status O3
Outage – extended until October 17 due to a defective pipe connected to the reactor.
The reactor has been offline for half a year. Why is the repair taken so long?
- Whenever an incident occurs at OKG, safety has the highest priority. For that reason, we conduct thorough investigations, develop and test repair methods before implementation, and inspect corresponding equipment before starting the plant.
You have already postponed the restart several times. How confident are you that the new date will be held?
- Our confidence in the restart increases the closer we get. There are still uncertainties, but the stated restart date is our best assessment now.
Could the situation have been avoided through other maintenance routines?
- We have extensive and well-proven maintenance routines. In connection with the current situation, we are reviewing the possibilities of further strengthening these routines to prevent similar issues in the future.
Are there other pipe connections to the reactor that could be damaged?
- We have thoroughly inspected all identical and similar pipe connections and found them to be intact.
Once the pipe damage is repaired, how long will it take before the plant can deliver electricity again?
- After the repair, we will restore the plant according to standard procedures. The process takes approximately two weeks, which is included in our restart plans. Oskarshamn 3 will deliver electricity at least until 2045.
The reactor supplies eight per cent of Sweden’s electricity. What impact will the extended shutdown have on electricity prices in Sweden?
- It comes down to supply and demand. Our electricity system is more complex than before, which makes it difficult to point to the exact consequences. When supply changes, prices change as well. The outcome depends on a range of factors: the status of solar, wind, and hydropower, as well as demand in neighboring countries. In other words, there is no clear answer.
You are investigating whether the reactor’s lifetime can be extended far beyond 2050. How realistic is that? Can nuclear power be trusted?
- The fewer reactors we have, the more sensitive the system becomes to disruptions. That is why it is vital that the nuclear fleet provides stability and can handle unplanned outages. We plan to operate Oskarshamn 3 until 2045 and are assessing the conditions for operating the plant for an additional 20 years beyond that.
