Hungary’s Paks nuclear power plant is facing potential operational challenges due to the ongoing heatwave and rising Danube River temperatures. The plant, which provides a significant portion of the country’s electricity, relies on the river for cooling water. Water temperatures are nearing levels that could force a reduction in output or even a temporary shutdown to prevent damage to the reactor. Officials are monitoring the situation closely and considering potential mitigation measures, but have not yet announced any changes to operations. Lower river levels, exacerbated by drought conditions, are compounding the problem, limiting the available water volume. This situation highlights the vulnerability of nuclear power plants to extreme weather events and the increasing pressure on water resources in Europe. The plant operator, MVM, assures that safety remains the top priority and they are prepared to act if necessary.
