Rotating equipments, such as blowers and pumps, play an important role for securing safety of the Tokai Reprocessing Plant. Bearings in the rotating equipments are one of the important machine components for stable operation. The most important control item for the bearings management is to mainta in lubrication system any time. Oil slick thickness in the bearings can be quantitatively confirmed by the shock pulse method, though it was difficu lt with conventional vibration method to confirm it. This meth...

Development of maintenance technology for rotation equipments in the Tokai Reprocessing Plant IIEquipment diagnosis by using the shock pulse method

The Tokai Reprocessing Plant has recovered nuclear materials from spent nuclear fuel. Reprocessing process is consisted of shearing process, a dissolution process and an extraction process etc. Each facilities designed to confine radioactive materials in controlled area to keep negative pressure using ventilation system. This system has been used over 40 years. We analyzed influences to the trouble of aging equipment, and we considered necessary additional check out system to prevent troubles based on ...
