Zusammenfassung:PROBLEM TO BE SOLVED: To efficiently grasp contents of abnormality when an alarm of a control rod operation monitoring system is issued.SOLUTION: A control rod operation monitoring system includes: a plurality of on-site control devices; and a control rod operation monitoring panel which issues a command signal concerning a location of each control rod to the on-site control devices and receives information from the on-site control devices while creating display information data to identify a cause of abnormality when the abnormality has occurred in at least one of the control rods and displaying a screen to identify a cause of the abnormality on the basis of the display information. The control rod operation monitoring panel includes: a storage part 22 having a database 22a in which information for identifying the cause of the abnormality is classified per control rod concerning latest data on a plurality of control rods; an operation part 21 for creating screen display data on the basis of the database 22a; and a state display part 23 for performing screen display on the basis of the screen display data created by the operation part 21.SELECTED DRAWING: Figure 2 【課題】制御棒操作監視システムの警報が発生した場合に効率的に異常内容を把握する。【解決手段】実施形態によれば、制御棒操作監視システムは、複数の現場制御装置と、これらに制御棒の位置に関する指令信号を発し、現場制御装置からの情報を受け入れるとともに、制御棒の少なくとも一つに異常が発生した場合に、異常原因の特定のための表示情報データを作成しこの表示情報に基づいて異常原因特定のための画面を表示する制御棒操作監視盤と、を有する。制御棒操作監視盤は、複数の制御棒に関する最新のデータについて異常原因特定のための情報が制御棒ごとに区分されたデータベース22aを有する記憶部22と、データベース22aに基づいて画面表示データを作成する演算部21と、演算部21で作成された画面表示データに基づいて画面表示する状態表示部23を有する。【選択図】図2
