CONTROL ROD DRIVE SYSTEM AND INSPECTION METHOD OF CONTROL ROD DRIVE SYSTEM

摘要

To provide a control rod drive system and an inspection method of the control rod drive system capable of performing inspection safely and effectively. A control rod drive system controlling operation by supplying a hydraulic pressure to control rod drive mechanisms includes a plurality of first hydraulic control units supplying the hydraulic pressure to corresponding given control rod drive mechanisms and a second hydraulic control unit supplying the hydraulic pressure to corresponding given control rod drive mechanisms of the first hydraulic control unit as an inspection target instead of the first hydraulic control unit as the inspection target selected from the respective first hydraulic control units.
