Temelín's Unit 1 began to deliver electricity into the grid again at 50 % of the reactor rated power. The energy sector is now waiting for tests at eighty percent of reactor rated power and verification of the proper functioning of the equipment in both the nuclear and non-nuclear parts.
"We verify the even distribution of power in the reactor, and we also closely monitor the turbine set, where hundredths of millimeters decide at its operation. The first days will show us whether it will be necessary to tune the settings of the turbine generator,"
The work around the generator, the equipment where electricity is directly produced, was highly demanding. "We changed the generator shield and also its rotor. Recently, we have a checked rotor in the machine, which has previously served as a backup. We do this replacement regularly every few years,” added Jan Kruml.
During the outage, technicians exchanged forty-two of the 163 fuel assemblies, checked safety systems, or conducted a six dozen investment actions. Including the external suppliers, around a thousand people participated in the outage works.
"We plan and coordinate the outages of our six nuclear units so that there is minimal concurrence. From Temelín, the work is now moving smoothly to the shutdown of the fourth Unit in Dukovany, which began at the end of last week,”
Another outage awaits Temelín in the second half of July. The technicians try to replace the fuel assemblies in the largest Czech Units in a period of lower consumption and higher production from renewable sources.
