Europe runs its grid on nuclear power and smug speeches about sustainability. Now the continent has heat. Also drought. Reactors need cold water to avoid becoming expensive paperweights. France is cutting output. Romania might shut down an entire reactor. Turns out atoms don't split better when you ask them nicely in French.
The technical term for what's happening is "reduced thermal efficiency due to insufficient coolant temperature differential." The accurate term is "we built these things next to rivers that are now too hot and too shallow to do the one job we needed them for." France has been dumping lukewarm water back into rivers for weeks. The fish are thrilled. The grid operators are refreshing their LinkedIn profiles.
Romania's reactor situation is particularly funny because shutting down nuclear capacity during an energy crisis is like selling your car during a gas shortage. It solves exactly nothing. But the alternative is letting the thing overheat, which solves even less and comes with the bonus prize of explaining to the EU why half the Danube is glowing.
Every energy analyst with a podcast is now explaining why this was predictable. Climate models warned us. Engineering reports flagged it. Nobody listened because "nuclear winter" was supposed to be the problem, not nuclear summer. The irony is so thick you could cool a reactor with it.
Retail traders who bought uranium stocks six months ago are currently Googling whether reactors use more fuel when they're struggling. They do not. The fuel burns the same. The electricity just doesn't get made. This is somehow a surprise to people who thought "clean energy" meant "works in all weather conditions."
France has eleven reactors running at reduced capacity. That's not a energy policy. That's a cry for help translated through a government press release. Romania's potential shutdown is even better. Nothing says "energy independence" like turning off your own power because the weather got spicy.
The real winners here are the Germans who shut down their nuclear plants early and now get to watch France learn why that was arguably premature.
