Power company Vattenfall has been given approval by the Swedish Radiation Safety Authority (SSM) and grid operator Svenska Kraftnät for test operation of Unit 1 of the Forsmark nuclear power station at an increased power level.

The boiling water reactor unit’s increased output means its net electrical power will increase by just over 50 MW to around 950 MW.

It marks the first step in a plan to increase the plant’s net power output by just over 100 MW. The second step will follow in 2023 or later, but will also need SSM’s approval.

The Forsmark nuclear station in Uppland, north of Stockholm, has three plants. The power at Forsmark-2 was increased by just over 100 MW in 2013.

Sweden's incoming centre-right coalition government has adopted a positive stance towards nuclear energy, calling for state-owned energy company Vattenfall to investigate the possible restart of Ringhals units 1 and 2, as well as to prepare for the construction of new reactors.

Country becomes latest to turn to reactors for low-carbon energy security Vattenfall is majority owner of three operational reactors at Forsmark (pictured) and two at Ringhals. Sweden’s incoming government will ask state-run utility Vattenfall to plan and procure new nuclear power stations – potentially making the country one of an increasing number turning to commercial reactors as a source of low-carbon, baseload energy supply.

“New reactors will be built in Sweden,” said Ebba Busch, whose Christian Democrat party belongs to an alliance that won the most seats in last month’s general election. The right-wing bloc is scheduled to become the Nordic nation’s next government in a parliamentary vote next week.

Sweden now joins other countries in Europe that are turning to nuclear power in response to record high energy prices and fears over the security of key infrastructure.

Swedes have debated nuclear power for decades, but the energy source has garnered popular support recently amid the ongoing power crunch.

Swedish utility Vattenfall has delayed the restart of unit 4 at the Ringhals NPP by two months to 31 January 2023. "The unforeseen required repairs are taking more time than expected, before starting up the unit after the yearly maintenance," Vattenfall said in a regulatory filing.

Repairs taking more time than expected, says utility The Ringhals nuclear power station in Sweden. Curtesy Vattenfall. Swedish utility Vattenfall has delayed the restart of the Ringhals-4 nuclear power plant by two months to 31 January. “The unforeseen required repairs are taking more time than expected, before starting up the unit after the yearly maintenance,” Vattenfall said in a regulatory filing.

Ringhals-4, a 1,130-MW pressurised water reactor (PWR) unit that began commercial operation in 1983, was shut down in mid-August for annual maintenance when a pressure retainer was damaged.

The repair work was estimated to take three months and the planned restart was to take place at the end of November.

Anna Collin, press officer at Ringhals, said: “We informed the market that the shutdown of Ringhals-4 will be extended to 31 January. This is because ever since the damage occurred, work has been done to come up with a plan of how long it will take to restore the damaged component.”

With electricity consumption in Sweden expected to increase rapidly in the coming decades, power company Vattenfall said on 28 June that it is working to find how different fossil-free energy sources can satisfy the increased demand. As part of this, Vattenfall is initiating a pilot study looking at the conditions for building at least two small modular reactors (SMRs) adjacent to the NPP.

Country needs fossil-free sources to meet growing power demand Vattenfall is majority owner of two commercial reactors at Ringhals (pictured) and three at Forsmark. Image courtesy Vattenfall. Swedish utility Vattenfall announced today it will be starting work on a pilot study on the feasibility of deployment of at least two small modular reactor (SMR) units at the site of the Ringhals nuclear power station.

Vattenfall said the study is focusing on Ringhals in southern Sweden because more electricity generation is expected to be needed in those areas. Two reactor units are currently in commercial operation at Ringhals-3 and -4.

Anna Borg, chief executive of Vattenfall, said fossil-free energy sources will be necessary to meet increasing demand for electric power in Sweden while SMRs are such a technology that has “come a long way in recent times” and therefore the company wants to look at the conditions for building SMRs near Ringhals.

Electricity generation is vital in the response to the COVID-19 pandemic, but scheduled refuelling and maintenance outages at nuclear power plants around the world must still go ahead. Operators are introducing risk-minimising procedures so outages that have been planned years in advance can proceed, while some are being prompted to rethink or extend scheduled outages.

The Swedish Parliament - the Riksdag - yesterday narrowly rejected a proposal from the nationalist Sweden Democrats party to reverse the planned closure of the two oldest reactors at the Ringhals nuclear power plant. Unit 2 of the plant was shut down at the end of last year, with unit 1 set to close later this year.
