Of the four blocks, only one is fully steam-powered, but the rest is actually rotating.

Like Napi.hu ForemanThe performance of the Paks Nuclear Power Plant began to decline from 3 am Sunday, and the index fell by hundreds of megawatts. Plus, it wasn’t even possible to figure out the cause for a long time. It stagnated at around five in the morning, and between three and four in the afternoon, energy production began to slowly creep in.

All this can be seen on the chart posted on mavir.hu (the two lower dark parts indicate Paks, the falls are marked by an orange circle):

Production has been around 1,000 megawatts for a long time, although the four operating units have a nominal capacity of 2,000 megawatts. True, work is under way on a comprehensive overhaul in Unit 1, but that alone does not explain the disappearance of half of the output. It was later announced on the website of the operating company of the facility, that units 2 and 3 were loaded with a total of 340 MW due to the planned schedule of 03:00.

The event is not considered malfunction.

In consultation with the MAVIR operator. According to the schedule, the two units will operate again at rated power by 19:00.
