Nuclear power is at the core of the Swedish electricity system and Vattenfall is focusing on safe and profitable operations for its five commercial reactors at the Ringhals and Forsmark nuclear stations until the 2040s, the company said in its annual and sustainability report for 2020.

At the end of 2020 Vattenfall, Sweden’s largest owner of nuclear power, closed its oldest reactor, Ringhals-1, in accordance with a decision made five years ago.

In December 2019, Ringhals-2 was permanently shut down after more than 43 years of commercial operation.

Vattenfall said in 2015 that it would close the two Ringhals plants as a result of falling demand, the falling price of electricity and the units being in need of costly maintenance.
