Oskarshamn nuclear power plant - OKG (to the startpage)

Oskarshamn 3 ready for long-term operation

December 21, 2020

During the autumn, a supplementary security system was installed at OKG. As the Swedish Radiation Safety Authority has announced that the installation is considered to meet the requirements for an independent core cooling, fossil-free electricity production at Oskarshamn 3 will be secured for many years to come.

In the long-term plans for Oskarshamn 3 (O3), the plant is forecast to supply electricity for at least another twenty-five years. An important parameter in these plans has been to meet the regulatory requirements for having installed the new safety system for independent core cooling by 31 December 2020.

The design of such an installation has been going on at OKG for several years and during this year's maintenance shutdown, the required upgrades were carried out. In parallel with this work, the Swedish Radiation Safety Authority, SSM, has reviewed and evaluated the current design solutions.

On Friday, SSM announced that its valuation means that OKG's system solution meets the set requirements and that there are no obstacles to long-term operation at O3 after the turn of the year.
