女川原子力発電所２号機復水移送ポンプ電動機における振動上昇事象への対応について
概要
By the vibration diagnosis, which is conducted for the purpose of condition monitoring (CM) and condition-based maintenance (CBM) in Onagawa NPS unit-2, vibration increasing of a motor for a condensate transfer pump was confirmed. We introduce the case where treatment was performed to the motor before loss of function because the diagnosis data could detect abnormal condition early and cause factor estimation.
