The Basic Results of Alignment and Summary of Operations of the Main K-1000-60/3000 Turbine Unit with a Small Number of Bearings at the Bushehr Nuclear Power Plant

Abstract

The results of vibration alignment and the first years of use of the prototype K-1000-60/3000-3 turbine unit of the Bushehr NPP in 2011 – 2016 are examined. As a result of conducting an extensive set of studies and actions, the claimed high-quality operating characteristics of the new design bearings that were used and the high degree of vibrational reliability of the turbine unit were confirmed, and these made it possible to ensure successful commissioning on a short timeline, despite the novelty of the design and the uniqueness of development of the majority of units, taking into account the integration of the equipment with the existing base and the condenser group. During the commissioning work, it was shown that this turbine unit is not inferior in any manner to turbine units of analogous power from other firms.
