Switzerland un-bans nuclear by 100-98, but the real fight is the referendum
While the National Council passed the repeal by a two-vote margin, Greenpeace projected radioactivity symbols onto the Federal Palace. The text now goes to the people, and a Swiss voter in the thread says left and green parties will fight it the whole way.
The vote that lifted Switzerland's post-Fukushima nuclear ban came down to 100-98 in the lower house, an indirect counterproposal to the 'Blackout Initiative'. Nothing gets built yet. The repeal still has to clear a mandatory popular referendum.
A Swiss voter laid out why it matters anyway: 50% of the country's energy is still oil and gas, two-thirds of its electricity is hydro fed by glaciers that are melting, and prices are 'sky-high'. The thread's sharper economists fired back that wind and solar already beat nuclear on cost.
A two-vote margin and radioactivity symbols on the Federal Palace
On June 18, 2026, Switzerland's National Council voted to lift the country's ban on building new nuclear plants. The margin was razor-thin: the repeal passed 100-98, and while the chamber debated, Greenpeace projected radioactivity symbols onto the Federal Palace.
The ban itself dates to the 2017 Energy Act, written in the aftermath of Fukushima, which blocked framework permits for new reactors. What parliament approved is not a construction program but an indirect counterproposal to the 'Blackout Initiative' that removes the legislative prohibition. The committee that sent it forward had split 13-12. The story ran hot on HN, drawing over 700 comments.
Why a country two-thirds powered by hydro is reaching for reactors
The most grounded case for the repeal came not from a lobbyist but from a resident voting on it.
"50% of all energy in the swiss economy is oil / gas. Of the remaining 50% (electricity), 2/3 are generated by hydro… To remain a competitive industrial economy, to transition away from oil/gas, and to offset any potential losses of hydro power as glaciers melt, nuclear + solar is the only real path for switzerland." — a self-identified Swiss voter
A Swiss commenter who works on the seasonality problem filled in the hardest constraint: the dams are full in spring and summer from snowmelt and sun, and far thinner in winter, exactly when demand peaks.
"We can still improve 10 to 20% our hydro production, but that's it… We may need it on the second half of the century, especially if we are going to electrify all forms of transport. We can't be buying France's nuclear energy all the time." — a Swiss commenter on the winter-demand gap
"A world-wide competition to generate the most expensive electricity"
The sharpest pushback was economic, not safety-based. Costs at recent megaprojects keep cited as the case against.
"It's a world-wide competition to generate the most expensive electricity! The record is currently held by Vogtle in Georgia US, but Ontario Canada is trying to take the crown by spending $500B on nuclear." — a reader in Ottawa
That framing got an inconvenient local reply. A commenter pointed to a Swiss utility's own price sheet:
"That competition is handily won by wind and solar. In the meantime in Switzerland: 'Our cheapest electricity product is nuclear electricity.'" — mpweiher, who linked the utility's tariff page
Others argued the ban was the wrong tool regardless of cost. "'I expect they're too expensive' is a terrible reason to ban them," wrote one engineer in the thread; banning commercial plants also starves the research that might make thorium or breeder designs viable.
The vote that matters hasn't happened yet
The parliamentary win is procedural. As several Swiss commenters stressed, the repeal triggers a mandatory referendum, and the left and green parties are mobilized against it. The 100-98 count is a preview of a national argument, not its verdict. If Switzerland, with cheap hydro, expensive electricity, and melting glaciers, can't agree on whether to keep the door open, the rest of Europe's nuclear debates won't get any quieter.
