Slovenia's Krško Nuclear Power Plant Returns to Full Power Operation

On the evening of August 18, 2026, as meteorological conditions further improved, temperatures dropped, and river water temperatures declined, the Krško Nuclear Power Plant (NEK) increased reactor power to 100%, resuming full-load operation.

During full-power operation, the plant will keep the entire cooling tower system in service to ensure compliance with relevant environmental limits and reduce the need for water withdrawal from the Sava River for cooling the plant's tertiary circuit.

Previously, due to environmental restrictions related to the Sava River, the Krško Nuclear Power Plant reduced unit power to 80% on August 6, 2026. On August 14, following preliminary improvements in meteorological conditions, plant power was increased to 90%.

Under the special operating conditions of this summer, the region experienced both low water levels and prolonged heat waves. While maintaining electricity generation, the Krško Nuclear Power Plant also provided necessary voltage support to the regional power system, contributing to enhanced stability and reliability of grid operation across a wider area.
