The first unit's generator is scheduled to be disconnected from the grid on Friday evening at approximately one-third of the reactor's rated output. According to the power plant's management, this will be a standard outage involving important inspections and investment activities.

„We will replace 54 of the total 163 fuel assemblies, which will enable the unit to operate for additional two months, bringing the total to fourteen months. This will also enable the first unit to switch to a longer fuel cycle. As usual, we will check the safety systems during the shutdown, and we have a lot of checks ahead of us around the turbine and generator,“

In addition to these checks, technicians will carry out 70 investment projects aimed at modernising the power plant and further strengthening its safety. These include modernising safety valves on the essential service water system and replacing one of the important fire tanks. The modernisation of the power plant's control system, on which the power plant has been working since 2022, will enter its final phase.

Since the beginning of the year, the Temelín power plant has produced 7.9 terawatt hours of electricity. Together with Dukovany, these are sources that produce the largest amount of clean electricity and thus contribute significantly to ČEZ Group's emission-free production. Annually, approximately two tens of millions of tons of CO₂ have not been released into the atmosphere thanks to nuclear power plants.
