Romanian navy blasts Danube rocks to keep Cernavoda nuclear plant running
The blast was carried out as the Danube fell to historic lows, threatening cooling water for the Cernavoda nuclear power station.

要点
Romania's navy detonated a rock outcrop in the Danube River to redirect water toward the Cernavoda nuclear plant. The measure was taken amid record‑low river levels that risked a shutdown of the plant, which supplies a large share of the country's electricity.
In early August 2026, the Romanian navy carried out a controlled explosion on a rock formation in the Danube River.2 The blast was intended to increase water flow toward the Cernavoda nuclear power plant, Romania's primary nuclear facility.5 The plant had been threatened with shutdown because the drought had reduced Danube water to historic lows, limiting cooling water availability.3
The operation aimed to prevent the plant from reducing output or stopping production, which could affect national electricity supply.1 Romanian authorities reported that the explosion successfully redirected water, improving cooling conditions for the reactor.6 Neighbouring Hungary's Paks nuclear plant was operating at about 10% capacity due to the same shortage of cooling water.9
Both Romania and Hungary asked consumers and businesses to cut electricity use to ease demand on the strained power systems.1 The Danube's water level had fallen to record lows across Central and Eastern Europe as a result of prolonged heatwaves and lack of rainfall.8 The naval rock‑blasting was part of broader emergency measures to maintain nuclear safety and support regional energy stability.7
なぜ重要か
The Danube River provides cooling water for several nuclear plants in the region, including Romania's Cernavoda and Hungary's Paks facilities.9
Cernavoda is Romania's only operating nuclear power plant and relies on Danube water to keep its reactor cores at safe temperatures.5
A summer heatwave and lack of precipitation caused the Danube to reach historic low levels, creating a water shortage for cooling and hydroelectric generation.8
Using explosives to clear river obstacles is an unusual emergency response, employed here to ensure sufficient water flow to the nuclear plant.4
