Nuclear reactor fuel cluster control rod connection/disconnection monitoring comprises use of visual markers on control rod connection/disconnection tool

摘要

The process is operated from a mobile gantry (52) over a nuclear reactor pond (2) and uses first and second visual markers (53) to monitor the connection and disconnection of the control rod (12). The markers are located on the control rod connection/disconnection tool (14), and are used to provide a visual monitoring check on the position of the control rod, viewed by a camera (55), before and after actuating the tool to ensure that the required operation has taken place.
