Today, the Slovenian Nuclear Safety Administration conducted an extraordinary inspection, where the actions after the reactor trip were verified. After the performed walkdowns, equipment check-ups and tests it was concluded that the necessary conditions for the Krško NPP start-up are met. A more detailed analysis of the event will be conducted in the coming days.

The Krško NPP began with the reactor start-up at 15:30 today. The power plant will be connected to the grid again around 22:00.
