Less dependence on fossil fuels, more control over our own supply
In a decision that reframes decades of national consensus, Belgium has moved to reclaim sovereign control over its nuclear energy infrastructure, purchasing the country's entire reactor fleet from French utility Engie. Prime Minister Bart De Wever has cast the acquisition not as a retreat from caution, but as a necessary reckoning with the vulnerabilities of energy dependence. The move places Belgium among a growing number of European nations reconsidering nuclear power not as a legacy risk, but as a pillar of long-term resilience.
- Belgium is reversing over twenty years of nuclear phase-out policy in a single sweeping acquisition, signaling that energy security now outweighs the safety anxieties that once drove decommissioning.
- Five reactors that were already shut down and headed for dismantlement will instead be preserved — a suspension of the wrecking ball that few anticipated even months ago.
- Neighboring countries, particularly Germany, have long viewed Belgium's aging reactors with alarm; Aachen once distributed iodine tablets to residents fearing radiation from the cracked and leaking Tihange plant.
- The government and Engie are racing toward an October 1st deadline to finalize the takeover, with ambitions stretching beyond maintenance to the construction of entirely new nuclear capacity.
- Belgium's bet is that the compounded risks of fossil fuel dependence and climate inaction are more dangerous than the technical challenges of extending the life of aging reactors.
Belgium's government announced this week that it will purchase the country's entire nuclear fleet from French utility Engie — a reversal so complete it amounts to a repudiation of energy policy that has governed the nation for more than two decades. Prime Minister Bart De Wever framed the acquisition as a matter of national security, a way to claim sovereign control over Belgium's power supply and reduce dependence on imported fossil fuels.
The deal covers seven reactors in total. Two are currently operational at the Doel and Tihange plants, both recently licensed to run until 2035. The remaining five were taken offline between 2022 and 2025 and were scheduled for dismantlement under the old decommissioning plan. That plan is now suspended. The government intends to maintain all seven reactors and eventually build new nuclear capacity alongside them.
The about-face is striking. In the early 2000s, Belgium passed legislation phasing out nuclear power entirely, driven by genuine safety concerns — capping reactor lifespans at forty years and banning new construction. That policy held for two decades. The Tihange plant in particular had been a source of cross-border tension, having experienced cracks and water leaks serious enough that the German city of Aachen distributed iodine tablets to residents in 2017 as a precaution against potential radiation exposure.
De Wever's government is betting the risks are worth it. The joint statement from the government and Engie frames the takeover as serving energy security, climate goals, industrial competitiveness, and long-term economic stability simultaneously. The two parties aim to finalize the agreement by October 1st. Whether Belgium's neighbors will accept the calculation that aging reactors are safer than energy insecurity remains an open and consequential question.
Belgium's government announced this week that it will buy the country's entire nuclear fleet from the French utility Engie, a reversal so complete it amounts to a repudiation of energy policy that has governed the nation for more than two decades. Prime Minister Bart De Wever framed the acquisition as a matter of national security and economic survival—a way to wean Belgium off imported fossil fuels and claim sovereign control over its power supply.
The deal would give the state ownership of seven nuclear reactors. Only two are running at the moment, both located at plants in Doel and Tihange, and both have just been granted permission to operate until 2035. The other five were taken offline between 2022 and 2025. Under the old decommissioning plan, those five were slated to be dismantled. That will no longer happen. Instead, the government and Engie say they intend to keep the reactors in place, maintain them, and eventually build new nuclear capacity on top of what already exists.
This is a striking about-face. In the early 2000s, Belgium passed legislation that effectively phased out nuclear power, driven by safety concerns that were serious enough to ban new reactor construction and cap the lifespan of existing ones at forty years. For two decades, that policy held. Now it is being suspended, and the government is signaling that nuclear energy will be central to Belgium's energy future, not a relic of it.
The reactors themselves have been a source of friction for years, particularly with neighboring countries. They have been shut down repeatedly for safety inspections. In 2015, when Belgium proposed extending their operational lives beyond the original forty-year design window, complaints came from across the border. Germany took the concerns seriously enough that the city of Aachen began distributing iodine tablets to residents in 2017, a precaution against potential radiation exposure from the aging Tihange facility, which had experienced cracks and water leaks.
De Wever's government is betting that the political and technical risks are worth the payoff. The statement released jointly by the government and Engie emphasizes that the move serves multiple objectives at once: energy security, climate goals, industrial competitiveness, and long-term economic stability. The two parties say they aim to finalize the takeover agreement by October 1st.
What makes this moment significant is not just the policy reversal itself, but what it signals about how European governments are reassessing their energy options. Belgium is choosing to double down on nuclear at a moment when many other nations are doing the same, driven by the dual pressure of climate commitments and the need to reduce dependence on imported energy. The move also reflects a calculation that the risks of aging reactors are manageable compared to the risks of energy insecurity and carbon emissions. Whether neighboring countries will accept that calculation remains to be seen.

Why is Belgium doing this now, after rejecting nuclear for so long?
The calculus has shifted. Climate change is real, energy prices are volatile, and fossil fuel imports are a vulnerability. Nuclear suddenly looks less like a relic and more like a necessity.
But those reactors are old. Aren't they dangerous?
They've had problems—cracks, leaks, repeated shutdowns. But the government is arguing that the risk of keeping them running is smaller than the risk of losing them and having to burn more gas and coal.
What about the neighbors? Germany was handing out iodine pills.
That's the real political problem. This isn't just a Belgian decision. It affects people in Germany, the Netherlands, Luxembourg. Those countries will have opinions, and they may not be quiet about them.
Is this about climate, or is it about money?
Both. The government says it's about climate and security. But Engie is a private company, and the state is buying assets. There's a financial transaction underneath the rhetoric.
What happens if one of these reactors fails?
That's the question no one wants to answer directly. The government is betting it won't. But if it does, the political cost will be enormous.
