Unit 2 has also officially switched to the so-called longer fuel cycle and will be in operation for two months longer.
"We have loaded more fresh fuel assemblies into the reactor, namely 54 instead of the previously loaded 36 out of a total of 163 assemblies. As a result, Unit 2 will be in operation for 14 months. Its next outage will not be until the beginning of 2026,"
In terms of the scope of work, this was the largest outage in history for Temelín. In total, power engineers managed over 21 thousand works and inspections during two months. This is four thousand more than during a normal outage.
"We are switching to longer operation between outages and we want to make sure that it will be safe and reliable. That's why, over and above the standard range of checks, we also completely overhauled all four turbine rotors and replaced the generator rotor. The safety systems were also extensively inspected, and all this was naturally reflected in the scope of work,"
Almost two thousand people from ČEZ and contractors were involved in the work. The contractors in particular will move to Dukovany in the coming weeks for the outage that will start at Unit 4 at the end of the year.
The Temelín's Unit 2 began to deliver electricity into transmission grid again at the 50 % of the reactor rated power. It should reach full power within a few days. There are still a few more tests to be made during the startup. For example, at 80% of reactor rated power, they will verify the even spatial distribution of reactor power. They will also monitor the turbine, where hundredths of a millimeter are crucial in operation.
Since the beginning of the year, the Temelín power plant has produced 13.7 terawatt hours of electricity. Together with Dukovany, these sources produce the most significant 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.
