Sweden Breaks 50-Year Nuclear Taboo With Revolutionary Mini-Reactors

A nuclear renaissance is unfolding in Sweden. After decades of nuclear hesitation, the Swedes are diving headfirst into mini-reactor technology. Talk about a plot twist. The country that once planned to phase out nuclear power is now embracing it with open arms.

Vattenfall, Sweden’s state-owned power company, has narrowed down its search to two suppliers for small modular reactors (SMRs): GE Vernova and Rolls-Royce. Just two finalists from an initial pool of 75. Pretty exclusive club, right?

After reviewing 75 candidates, Vattenfall has narrowed its SMR suppliers to just GE Vernova and Rolls-Royce. Exclusive energy club indeed.

These mini-reactors are destined for the Ringhals site on the Värö Peninsula. First new nuclear project in over 40 years. About time.

The BWRX-300 from GE Vernova brings 300 megawatts of power in a compact package. It’s the only SMR currently under construction in the Western world. Rolls-Royce counters with its own proven design, complete with established Swedish supply chain links. Both use nuclear fuel already supported in Sweden. No need to reinvent the wheel.

Sweden’s government isn’t just cheerleading from the sidelines. They’ve thrown serious weight behind this nuclear revival, offering up to 400 billion Swedish kronor (roughly $36 billion) in credit guarantees. That’s putting your money where your mouth is.

The parliament scrapped old restrictions on reactor numbers and locations too. Liberty to build, baby.

The Swedish nuclear roadmap is ambitious: two large-scale reactors by 2035, up to ten new reactors (including SMRs) by 2045. The BWRX-300 has been specifically selected to align with Sweden’s net zero ambitions for clean energy production. The plan includes installing either five BWRX-300 plants for a total of 1,500 MW or three Rolls-Royce SMR plants totaling 1,410 MW. Nuclear currently provides 28.6% of Sweden’s electricity from six reactors at three sites. That number’s about to grow.

Even advanced reactor tech is gaining momentum. Swedish company Blykalla is developing lead-cooled reactors with the Research Institutes of Sweden. Heavy industry needs clean energy too.

Sweden has officially broken its nuclear taboo. Their policy shift from “100% renewable” to “100% fossil-free” opened the door. Smart move.

Following the global trend where over 20 countries plan to increase nuclear capacity, Sweden’s energy transition aligns with the worldwide nuclear renaissance.

In Sweden’s energy future, these mini-reactors aren’t just an option—they’re essential. The nuclear renaissance isn’t coming. It’s here.
