Hungary's Paks nuclear plant drops to 25% output as Danube drought deepens, full shutdown expected this weekend

Summary

Hungary's Paks Nuclear Power Plant, which supplies roughly 40% of the country's electricity, was running at about 480 MW on August 1, around 25% of its 2,000 MW normal capacity, after low Danube River water levels forced the shutdown of two of its four reactor units in a matter of days. Prime Minister Peter Magyar said a complete plant shutdown could arrive this weekend, potentially weeks earlier than previously predicted, which would mark the first full outage in Paks's 44-year operating history. Hungarian energy experts quoted by [[444.hu]] said the greater danger is not the shutdown itself but the unknown restart timeline, because the Danube needs to recover before cooling water intake can resume. Separately, Romania's Cernavodă plant had already taken one unit offline for the same reason, compressing the region's nuclear output at once.

The split

Hungarian outlets led with expert alarm about a protracted outage and potential industrial power restrictions. Arab News and NBC News led with the historic "first shutdown in 44 years" angle and the regional electricity supply risk. Bloomberg reported the second block shutdown factually. No outlet disputed the operational figures; divergence was in framing: domestic Hungarian press emphasised the economic and social disruption, international outlets emphasised the European energy security dimension.

By the numbers

• 480 MW, approximate Paks output on August 1, versus 2,000 MW normal capacity
• 25%, share of capacity still operating as of Saturday morning
• 44 years, Paks operational life with no prior complete shutdown
• 2-3 cm per day, rate at which the Danube level was still falling as of August 1
• 4-5 days, window before Cernavodă cooling water intake becomes impossible, per Romanian water authority
• 40%, share of Hungary's electricity normally supplied by Paks

Why it matters

A full Paks shutdown would remove the largest single power source in Hungary from the grid at the height of summer heat, at the same time Romania is already restricting its nuclear output at Cernavodă. The outage creates immediate pressure to buy electricity from neighbouring countries or restart coal capacity, with analysts warning of sharp regional price spikes across Central Europe if the Danube low persists into late August.

What to watch

• Whether Paks achieves a full shutdown this weekend or maintains partial output
• Danube water-level readings at Paks and Cernavodă over the coming days
• Hungary's activation of industrial demand restrictions and the list of consumers targeted
• Cross-border electricity import arrangements and spot-price movements in Central European power markets
