Uniper and Fortum shut down Oskarshamn-1 nuclear reactor (Sweden)

OKG, the joint-venture between Uniper (54.5%) and Fortum (45.5%), has permanently shut down the first unit of the Oskarhamn nuclear power plant in Sweden, in line with the planning set previously in October 2015 and February 2016.



In June 2015, E.ON announced that it would start the closing process of the first two reactors, citing sustained low electricity prices, combined with the output tax on nuclear power, while Fortum expected to continue operations at Oskarshamn nuclear power units 1 and 2. In October 2015, the two companies reached an agreement and decided to shut down the reactors.



Oskarhamn-1 is a 473 MW BWR (boiling water reactor), which started operations in 1972, while Oskarshamn-2 is a 638 MWe BWR, which began operating in 1974 and has been offline since May 2013. It closed in 2015 and is currently scheduled for decommissioning in 2020. The Oskarhamn plant also includes a third unit of 1,400 MW, commissioned in 1985 and which will remain operational.
