Sweden Went Anti-Nuclear. Then It Changed Its Mind. Now It's Putting Real Money Down.

For decades, Sweden was the poster child for anti-nuclear politics. After Three Mile Island spooked the world, Sweden held a referendum in 1980 and voted to phase out nuclear entirely. That policy stood for 30 years.

In June 2010, Sweden's parliament repealed the phase-out. In June 2023, according to the World Nuclear Association, Sweden scrapped its 100% renewable electricity target and replaced it with a 100% fossil-free goal — language that explicitly lets nuclear back in. By November 2023, the government announced plans for two large-scale reactors by 2035 and the equivalent of 10 new reactors, including small modular reactors, by 2045.

Now they're moving from words to money.

Three Major Moves in One Week

In the span of roughly two weeks in late May and early June 2026, three major developments landed in rapid succession.

First: Blykalla filed the first application under Sweden's new government-led siting process. The proposed site is Norrsundet, and the plan calls for six 55-MWe SEALER lead-cooled reactors — 330 MWe total. CEO Jacob Stedman described it as a historic milestone and tied the technology directly to meeting surging AI and electrification demand with reliable baseload power. Blykalla already has a prototype facility underway at Oskarshamn and has partnered with Uniper, Oklo, and ABB.

Second: Studsvik filed for between 600 MW and 1,400 MW of new SMR capacity at its Nyköping site, about 100 kilometers south of Stockholm, according to reporting from Power Magazine and the American Nuclear Society. This is Studsvik's second application this spring — in March, its subsidiary Kärnfull Next filed for 1,200–1,600 MWe at a proposed campus in Valdemarsvik. Studsvik's leadership said plainly: "Sweden has decided to build new nuclear power, and the country needs new firm, fossil-free capacity on a scale not seen in a generation."

Third: On May 28, the Swedish government made public a proposal to take a 60% ownership stake in Videberg Kraft AB — the Vattenfall-led company pursuing up to 1,500 MWe of new SMR capacity at the existing Ringhals nuclear site on Sweden's southwestern coast. The financial structure includes an initial SEK 1.8 billion (about $194 million) capital injection and authority to deploy up to SEK 34.3 billion — roughly $3.7 billion — during construction.

The government also proposed absorbing a share of an estimated SEK 122 billion ($13.2 billion) in baseline fixed costs for a new nuclear waste management system, with potential state liability running from 2035 all the way to 2159. That is not a typo.

What the Government Is Actually Trying to Do

Acting Minister of Climate and Environment Johan Britz explained the logic directly: limit the first mover's share of fixed costs with the expectation that additional reactors get built and eventually share those costs. "We are already seeing interest from several actors in the construction of nuclear power facilities in Sweden," Britz said.

The approach mirrors the logic the U.S. used with loan guarantees at Vogtle — except Sweden is taking an equity stake rather than just backstopping debt. De-risk the first project so the second and third are easier to finance.

Videberg is currently choosing between five GE Vernova Hitachi BWRX-300 reactors or three Rolls-Royce SMRs. Selection is expected later this year, with a final investment decision targeted for 2029, according to ZeroHedge's industry summary citing Goldman Sachs analysis.

What Mainstream Coverage Is Missing

Most energy coverage of Sweden's nuclear revival focuses on a straightforward narrative of a green country embracing nuclear. The actual scale of what's being attempted and how far away delivery remains gets less attention.

Timelines for first power remain in the early 2030s at the absolute optimistic end. The final investment decision on Ringhals isn't until 2029. Visible construction is still years away on most of these projects. Sweden currently has six operable reactors generating about 29% of its electricity, per World Nuclear Association data from 2024. No new kilowatt has been added yet.

Also absent from most coverage: the engineering manpower problem. ZeroHedge noted that Studsvik's acquisition of Kärnfull Next highlights an ongoing skilled engineering bottleneck. You can file all the applications you want. Finding enough qualified nuclear engineers to build 10 reactors in 20 years is a separate challenge.

China's actual pace of reactor construction remains the real benchmark. Sweden is generating applications and government commitments. China is generating completed reactors.

What This Means for Energy Policy Everywhere

Sweden's story demonstrates that once a country goes anti-nuclear, policy can reverse. Governments can admit they were wrong. It just takes about 40 years and an energy crisis to get there.

The U.S. is watching. So is Germany, which is moving in the opposite direction and paying for it in higher electricity prices and increased fossil fuel dependence.

Steady baseload power doesn't care about political fashion. Sweden figured that out. Whether $3.7 billion in government capital and a stack of permit applications actually turns into operating reactors by 2035 — or becomes another expensive timeline that keeps slipping — remains to be seen.

The applications are filed. The money is proposed. The engineering work comes next.
