Fusion power
Regulatory framework and a national strategy for fusion power
What's at stake: Fusion power is a technology under development in which Swedish researchers and companies are among the international leaders. If today's regulatory framework, built for conventional nuclear power, is not adapted to fusion power's different risk and safety characteristics, it could affect Sweden's prospects of becoming a leader in the field.
Case texts and AI reasoning are AI-translated from the Swedish originals; the Swedish text is authoritative.
What the vote decides
The question is whether the Riksdag should direct the government to review a specially adapted regulatory framework for fusion energy and to draw up a national fusion strategy, or whether this should wait pending existing work on the regulatory framework for nuclear power.
Yes Yes — the committee proposal
The committee takes a positive view of new nuclear power's role in the energy system and of the work already under way to clarify the regulatory framework for nuclear power, but does not consider there to be grounds for the Riksdag to specifically direct the government to review a tailored regulatory framework for fusion power or to draw up a national fusion strategy at this time, and therefore rejects the motions.
No No — the reservations
Reservation 8 (S, V, C, MP)
The reservation (S, V, C, MP) calls for the government to investigate how the regulatory framework for fusion energy and fusion power plants can be updated and adapted, and to draw up a national fusion strategy covering areas such as infrastructure, skills supply, investment and partnerships. The reasoning is that today's framework is built for conventional (fission-based) nuclear power and does not meet fusion power's particular technical and risk-related characteristics, a point also raised by the Swedish Radiation Safety Authority.
Summarised from the committee report. Party labels in the summary come from the report, not from the vote.
What do the votes mean here?
Yes The committee proposal: rejecting the motions (keeping things as they are).
No Backing the counter-proposal: reservation 8 by S, V, C, MP.
Abstain The party marks a position of its own that is not one of the two final alternatives.
What each plan points to — and how the party voted
For each party: the vote its own election manifesto and party programme point to in this case, next to how the party actually voted. A plan can only point to Yes or No; a party can also abstain.

Riksdag decision: The Riksdag said no to 197 proposals in motions on energy policy. The proposals were submitted during the general motion period 2025. Among other things, the proposals concern the direction of energy policy, nuclear power, wind power, biofuels and biodiesel, energy efficiency, energy gases and heat and combined heat and power. The Riksdag refers, among other things, to the pursued policy and ongoing work.
Counter-proposals
- The counter-proposal wants the government to establish a cross-party energy commission, clarify energy policy targets of at least 60 TWh additional fossil-free power by 2030 and 2035, and reform permit processes for energy investments. (S, V, C, MP) — Reservation 8
Plan vs actual vote
Every party, in chamber order: what its own plan pointed to, how it voted, and the reasoning behind both. Highlighted rows are where the two differ — but a vote that follows the plan is a result too, so the reasoning is there for every party.
The plan's energy policy line is a strategy built on renewable electricity, and it explicitly rejects nuclear power expansion as a way out of fossil fuel dependence.
Plan documents: party programme
Reasoning and quotes
The plan's energy policy line is a strategy built on renewable electricity, and it explicitly rejects nuclear power expansion as a way out of fossil fuel dependence. A national fusion strategy intended to make Sweden a leader in nuclear technology points away from that prioritisation. At the same time the plan wants to see major joint investments in technology development and free research, which pulls in the other direction and makes the assessment uncertain.
Original (Swedish)
Planens energipolitiska linje är en strategi byggd på förnybar el, och den avvisar uttryckligen kärnkraftsutbyggnad som väg ur fossilberoendet. En nationell fusionsstrategi som ska göra Sverige ledande inom kärnteknik pekar bort från den prioriteringen. Samtidigt vill planen se stora gemensamma satsningar på teknikutveckling och fri forskning, vilket drar åt andra hållet och gör bedömningen osäker.

The plan takes no explicit position on what the committee actually decided — often because the committee's reason was procedural. The stance is derived and fully cited, but it does not show the party broke a commitment.
The election manifesto establishes that no sacred cows apply when Sweden's energy needs are to be solved and that the party views positively initiatives that explore the potential in all energy sources.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The election manifesto establishes that no sacred cows apply when Sweden's energy needs are to be solved and that the party views positively initiatives that explore the potential in all energy sources. Adapting the regulatory framework for fusion energy and developing a national strategy is just such an initiative, and also aligns with the plan's desire for Swedish industrial and research leadership. Fusion energy is not mentioned in the plan.
Original (Swedish)
Valmanifestet slår fast att inga heliga kor gäller när Sveriges energibehov ska lösas och att partiet ser positivt på initiativ som undersöker potentialen i samtliga energislag. Att anpassa regelverket för fusionskraft och ta fram en nationell strategi är just ett sådant initiativ, och ligger också i linje med planens vilja till svenskt industriellt och forskningsmässigt ledarskap. Fusionskraft nämns inte i planen.

- technology-neutral energy policy»När det gäller att lösa Sveriges energibehov finns inga heliga kor.« (2022 manifesto ↗)“When it comes to solving Sweden's energy needs, there are no sacred cows.”
- nuclear power as part of electricity system»Kärnkraften är en viktig del av svensk elproduktion och kommer att så vara under lång tid framöver.« (2022 manifesto ↗)“Nuclear power is an important part of Swedish electricity production and will remain so for a long time to come.”
- promoted research»Främjande av en fri kunskapssökande grundforskning.« (party programme ↗)“Promotion of free inquiry-based basic research.”
The plan's energy prioritisation is rapid expansion of renewables and energy efficiency, and it states that nuclear power takes too long in relation to how quickly emissions must decrease.
Plan documents: party programme
Reasoning and quotes
The plan's energy prioritisation is rapid expansion of renewables and energy efficiency, and it states that nuclear power takes too long in relation to how quickly emissions must decrease. A national fusion strategy with the aim of making Sweden a leader in nuclear power technology draws resources and attention from that prioritisation. The plan simultaneously values free research and new technology, which makes the conclusion uncertain.
Original (Swedish)
Planens energiprioritering är snabb utbyggnad av förnybart och energieffektivisering, och den slår fast att kärnkraft tar för lång tid i förhållande till hur snabbt utsläppen måste minska. En nationell fusionsstrategi med målet att göra Sverige ledande inom kärnkraftsteknik drar resurser och uppmärksamhet från den prioriteringen. Planen värnar samtidigt fri forskning och ny teknik, vilket gör slutsatsen osäker.
- no to new nuclear powerdecisive»Miljöpartiet motsätter sig ny kärnkraft i svensk energiförsörjning.« (party programme ↗)“The Green Party opposes new nuclear power in Swedish energy supply.”
- too slow technology»Dessutom är ny kärnkraft dyrare och tar för lång tid att bygga ut i förhållande till hur snabbt de fossila utsläppen behöver minska.« (party programme ↗)“Moreover, new nuclear power is more expensive and takes too long to build in relation to how quickly fossil emissions need to decrease.”
- renewables first»Därutöver vill vi i Miljöpartiet se en snabb utbyggnad av förnybar energi som vindkraft« (party programme ↗)“Furthermore, in the Green Party we want to see rapid expansion of renewable energy such as wind power”
- free research»Miljöpartiet vill satsa på fri och oberoende forskning med både bredd och spets.« (party programme ↗)“The Green Party wants to invest in free and independent research with both breadth and depth.”

The plan is built on the climate transition taking advantage of technology's possibilities and companies' innovation capacity, and establishes that regulations shall not brake green investments.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The plan is built on the climate transition taking advantage of technology's possibilities and companies' innovation capacity, and establishes that regulations shall not brake green investments. Investigating how regulations can be adapted to fusion power's special conditions and drawing up a national fusion strategy is in line with this, since fusion is not the fission power the party programme's vision distances itself from. The plan does not mention fusion, so the position is derived.
Original (Swedish)
Planen bygger klimatomställningen på att ta vara på teknikens möjligheter och företagens innovationskraft, och slår fast att regelverk inte får bromsa gröna investeringar. Att utreda hur regelverket kan anpassas till fusionskraftens särskilda förutsättningar och ta fram en nationell fusionsstrategi ligger i linje med detta, eftersom fusion inte är den fissionskraft partiprogrammets vision tar avstånd från. Planen nämner inte fusion, varför ställningstagandet härleds.

Reasoning and quotes
The election manifesto promises that nuclear power regulations will be modernized and that new technology is part of the solution to the climate challenge, which directly supports the demand for regulations adapted to fusion power's conditions. The plan also wishes to increase research funding and establishes that continued research and development are needed in the nuclear technology field. An investigation and a national fusion strategy are therefore in line with the plan.
Original (Swedish)
Valmanifestet lovar att regelverken för kärnkraft moderniseras och att ny teknik är en del av lösningen på klimatutmaningen, vilket direkt bär kravet på ett regelverk anpassat till fusionskraftens förutsättningar. Planen vill dessutom öka forskningsanslagen och slår fast att fortsatt forskning och utveckling behövs på kärnteknikområdet. En utredning och en nationell fusionsstrategi ligger därför i linje med planen.
- modernized nuclear power regulationsdecisive»I stället vill vi möjliggöra fler nya reaktorer på fler ställen, möjliggöra återstart av Ringhals 1 och 2, se till att statliga lånegarantier omfattar kärnkraften, modernisera regelverken och ge kärnkraften betalt för att den alltid finns tillgänglig.« (2022 manifesto ↗)“Instead we wish to enable more new reactors in more places, enable restart of Ringhals 1 and 2, ensure that state loan guarantees cover nuclear power, modernize the regulations and pay nuclear power for always being available.”
- new technology solves the climate challenge»Medan andra gröna partier grundades för att stoppa tillväxten vet vi att ny teknik och nya lösningar är en del av lösningen på klimatutmaningen.« (2022 manifesto ↗)“While other green parties were founded to stop growth we know that new technology and new solutions are part of the solution to the climate challenge.”
- research on nuclear technology»Fortsatt forskning och utveckling behövs för att minimera riskerna vid drift samt hantering av bränsle och avfall.« (party programme ↗)“Continued research and development are needed to minimize risks in operation and handling of fuel and waste.”
- increased research funding»Vi vill öka forskningsanslagen och både skapa bättre karriärvägar för yngre forskare och se riktade satsningar på att svenska universitet ska kunna locka hit världens främsta forskare.« (2022 manifesto ↗)“We wish to increase research funding and both create better career paths for younger researchers and see targeted efforts so that Swedish universities can attract the world's leading researchers.”

The counter-proposal wants to investigate how regulations can be adapted to fusion power and develop a national fusion strategy.
Plan documents: 2022 manifesto · party programme
Reasoning and quotes
The counter-proposal wants to investigate how regulations can be adapted to fusion power and develop a national fusion strategy. The plan uses the same method for new nuclear power: the Radiation Safety Authority shall receive resources to develop regulations, the ban on new reactor sites shall be removed and all fossil-free energy sources shall contribute. The party programme's confidence in technological development as a solution strengthens the conclusion.

Motförslaget vill utreda hur regelverket kan anpassas till fusionskraft och ta fram en nationell fusionsstrategi. Planen använder samma metod för ny kärnkraft: Strålsäkerhetsmyndigheten ska få resurser att ta fram ett regelverk, förbud mot nya reaktorlägen ska bort och alla fossilfria energikällor ska vara med och bidra. Idéprogrammets tilltro till teknisk utveckling som lösning stärker slutsatsen.

The party programme states that there are regulations in need of change that prevent new construction and make modern reactors impossible, and wants to invest more resources in new nuclear technology, including a Swedish research reactor. Investigating how regulations can be adapted to fusion power's prerequisites and drawing up a national fusion strategy is the same kind of commitment. The plan also wants to focus more on research and development to make fossil-free energy more profitable.
