Hungary fully shut down its sole nuclear power plant for the first time in its 44-year history on August 2, 2026, due to record-low Danube River water levels. Romania also cut nuclear output; both nations had previously reduced power generation as cooling-water levels fell to historic lows.
Romania has shut down both of its nuclear power reactors due to dangerously low Danube River water levels, which are needed for cooling. Hungary has also shut down one of its four Paks reactors for the same reason.
