Swedish energy company Vattenfall plans to build small modular reactors, known as SMRs, in its future nuclear power expansion. The plan is for new nuclear power to be operational in Sweden by the mid-2030s.
The small-scale nuclear reactors will be built on the Väröhalvön peninsula, where the Ringhals nuclear power plant is located, as the company considers it the “best location” to get new nuclear power operational in Sweden as quickly as possible. The state-owned energy company justifies the decision to use SMRs for technical reasons, but also because the peninsula has limited space.
— We have concluded that small is better than large conventional ones, Vattenfall CEO Anna Borg tells TT and continues:
— But it’s a broad concept, in this particular case the reactors are not very small but they are smaller than traditional large-scale ones. Large-scale reactors would have entailed higher risks for us at this specific site.
Vattenfall has moved forward with American GE Vernova and British Rolls-Royce, both of which manufacture SMRs. However, it’s not clear which one it will ultimately be, but the plan is to either start a project with five BWRX-300 reactors from GE Vernova or three Rolls-Royce SMRs. According to reports, this would provide a total capacity of 1,500 megawatts. For comparison, a 500-megawatt SMR has the same capacity as the first large-scale reactor in Oskarshamn, Sweden.
“First Swedish nuclear construction project in over 40 years“
Furthermore, the company is also exploring possibilities to build an additional 1,000 MW at the adjacent site where Ringhals 1 and 2 currently stand, but that would be a future project.
— This is another step toward the first Swedish nuclear construction project in over 40 years. Our goal is a successful project on the Väröhalvön peninsula, and by that we mean there are conditions to become operational within reasonable time and budget at the site we have available, says Borg in a press release.
The goal is for new nuclear power to be operational by the mid-2030s.
