Slovenia: Krško nuclear plant to cut output due to low Sava River levels

Slovenia's Krško Nuclear Power Plant is set to decrease its electricity production to 80% of its capacity. The decision stems from the exceptionally low water levels and high temperatures recorded in the Sava River, which is crucial for the plant's cooling systems.

In a statement, the power plant indicated that further reductions in output might be necessary if the prevailing hydrological and meteorological conditions persist or worsen. The ongoing heatwave and drought affecting Europe have led to significantly reduced river levels, raising concerns across various sectors, including water supply, transportation, and energy generation.

This development in Slovenia is part of a broader pattern of challenges faced by nuclear facilities across Europe due to extreme weather. On Monday, Romania resorted to blasting rock to facilitate water diversion from the Danube River to its sole operating nuclear reactor, essential for cooling. Meanwhile, Hungary announced it could maintain energy conservation measures at its nuclear plant for an additional two days.

The situation at Krško highlights the vulnerability of energy infrastructure to climate change impacts. The reliance on river water for cooling makes nuclear plants susceptible to disruptions during periods of drought and high temperatures, potentially affecting national energy security and requiring adaptive management strategies.
