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, when...

Krško Nuclear Power Plant to Reduce Power Output Due to Sava River Water Temperature Pressure

The Krško Nuclear Power Plant (Krško NPP) announced that, due to persistent abnormal hydrological and meteorological conditions in the Sava River, it will begin gradually reducing reactor power from the evening of August 6 to prevent river water temperatures from exceeding environmental standards. In the first phase, the unit's power output will be reduced to 80% of its maximum generating capacity. The plant stated that this power reduction is a planned, controlled, and temporary measure aimed at ensuring the Sava River water temperature remains within permissible limits. Relevant environmental standards stipulate that the daily average water temperature must not exceed 28 degrees Celsius, and the temperature increase of the river water caused by the plant's operation must not exceed 3 degrees Celsius. The management of the Krško Nuclear Power Plant also stated...

Croatia's Krško Nuclear Power Plant Only 3.4°C Away from Shutdown Threshold

Croatian Prime Minister Andrej Plenković on August 4 dismissed concerns that the Slovenia-Croatia jointly owned Krško nuclear power plant might be forced to shut down due to excessively high Sava River water temperatures, stating that power supply is secure and the situation is under control. However, the plant is actually approaching environmental cooling limits, and due to abnormally high temperatures and declining Sava River water levels, the safety limits at the Krško nuclear power plant are nearing critical thresholds. According to environmental regulations, the daily average temperature of the river at the complete mixing point must not exceed 28 degrees Celsius, and the daily temperature increase must not exceed 3 degrees Celsius. As of August 4, the Sava River in the area was 24.6 degrees Celsius, with a daily increase of 2.6 degrees Celsius, leaving only 3.4°C before the 28°C red line and 0.4°C before the 3°C daily increase red line...

Krško Nuclear Power Plant Operates at Full Capacity; Low Sava River Water Level May Affect Unit Output

Slovenia's Krško Nuclear Power Plant continues to operate at full capacity, but due to low water levels and elevated water temperatures in the nearby Sava River, a reduction in reactor power cannot be ruled out in the future. The plant stated that it is utilizing its cooling tower system and operating in compliance with environmental restrictions related to the Sava River. Due to insufficient recent precipitation, the Sava River's water level remains low, and river water temperatures are also staying in a higher range. Plant management also noted that increased cooling demands have already had a certain impact on the unit's power generation efficiency. Krško Nuclear Power Plant has notified relevant authorities in Slovenia and Croatia that if environmental restrictions are further tightened, it may be necessary to...
