Romania shuts final nuclear reactor as severe Danube drought forces emergency energy measures

Romania has completed a full shutdown of its Cernavoda nuclear power plant after severe drought dropped water levels in the Danube River to historic lows. The plant, which relies on the Danube for cooling and typically provides 20% of the country’s electricity generation, took its second reactor offline following the prior closure of its first reactor in late July.

State operator Nuclearelectrica stated that the second reactor was shut down due to the ongoing drop in water levels, with no restart anticipated for at least ten days. To mitigate the energy shortfall, Romania declared a state of emergency for August, activated a 330-megawatt lignite-fired power plant, and requested that major industrial consumers and households curb power use during peak hours. Major automakers including Dacia and Ford have paused domestic production to help conserve power.

The total shutdown immediately threatens energy security in neighbouring Moldova, which relies on Romanian imports to cover up to 60% of its electricity deficits. Moldovan authorities warned of potential rolling power cuts if alternative supplies cannot be secured from Ukraine or Western Europe. Across Europe, low river levels have similarly forced nuclear output reductions in France and triggered emergency engineering interventions in Hungary.
