Nuclearelectrica Disconnects 1 Reactor on Low Danube Levels as Heat Threatens $207.7 Billion EU Hit

Summary
Romania’s state-owned Nuclearelectrica took its only operating Cernavoda reactor off the grid in August after Danube levels fell too low to support cooling-water needs.
Temperatures above 30C and prolonged drought have shrunk rivers across Europe, forcing nuclear plants to curb output because warmer, shallower water breaches environmental limits meant to protect aquatic life.
Romania had already dredged the river, sunk rock-filled barges and used a controlled underwater blast to improve flow, but the measures failed to keep the unit online; Cernavoda’s two reactors normally supply about one-fifth of national electricity.
The strain is regional: Hungary’s Paks at one point had only 1 of 4 turbine units running, while France expected up to 15% of its nuclear fleet offline during August heat.
Triodos estimates Europe’s extreme-heat summer could cost about $207.7 billion—roughly 1% of EU GDP—adding urgency to plans for coastal siting, upgraded cooling systems and more diversified power supply.
If climate change renders river-cooled nuclear reactors inoperable during summer heatwaves, can Europe's energy grid survive without its primary baseload power source?
