Long-Term Bearing Wear Tests of Conventional Journal Bearings and Development of Hydrostatic Bearings for the LOFT Drag-Disc Turbine Transducer

摘要

The details of a two-year development program concerning materials for use as turbine bearings in a pressurized water reactor environment are reported. Two types of bearings have been examined, both conventional journal bearings and hydrostatic bearings. The results of long-term bearing wear tests conducted at 590 K and 15.1 MPa in water are presented. The feasibility of using hydrostatic bearings for the same transducer is demonstrated.
