On 22 and 23 April 2021, tests were carried out at MVE Kadaň during the operational and emergency shutdown of the turbine. The purpose of the tests was to measure the pressures in the interblade space of the turbine, radial vibrations and axial displacement of the shaft.

The measurement data will be used for the future overhaul of the turbine, especially for the possible installation of aeration valves, for determining the bearing clearance and for deciding on the type of new turbine shaft seal.
