SCIENTIFIC AND TECHNICAL COMMUNICATIONS: DEVELOPMENT OF HIGH-LOAD WATER-LUBRICATED RADIAL-AXIAL BEARINGS FOR ELECTRIC-PUMP UNITS IN THE FIRST LOOP OF A NUCLEAR POWER PLANT

摘要

The main circulation pump units play an important role in ensuring the operational and economic efficiency, reliability, and safety of nuclear power plants. These units are components of the main technological equipment which operates according to an active principle, operates for a long time, and is closely coupled with other equipment. At the present time, more than 70 GTsN-195M units are installed in power plants with VVER-1000 reactor [1] and more than 120 GTsN-317 units are installed in Plants with VVER-440 reactors. Both modifications of these units were developed in TsKBM and have a similar design (Fig. 1).
