🗞️ Driving the news: France’s Flamanville 3 nuclear reactor, its most powerful at 1,600 MW, has been connected to the grid after a 17-year build
The long-delayed European Pressurized Reactor (EPR) marks a key moment in France’s nuclear energy strategy despite significant delays and cost overruns

🔭 The context: Initially slated for completion in 2012, construction faced technical setbacks and ballooning costs, rising from €3.3 billion to €13.2 billion
The EPR is designed for higher efficiency and safety and is France’s first reactor start-up in 25 years, joining similar units in China and Finland

🌍 Why it matters for the planet: With nuclear power supplying around 60% of France's electricity, this reactor underscores nuclear energy's role in low-carbon energy production
It contrasts sharply with Germany’s nuclear exit and supports France’s push for energy independence and climate goals

⏭️ What's next: Testing of the reactor will continue through mid-2025, and a comprehensive inspection is planned for 2026
France plans six more EPR2 reactors, with potential for eight additional units, as part of its nuclear “renaissance”

💬 One quote: “Re-industrialising to produce low-carbon energy is French-style ecology. It strengthens our competitiveness and protects the climate.” — President Emmanuel Macron

📈 One stat: The Flamanville reactor will eventually supply electricity to over two million homes, bolstering France's energy grid
