Abstract
A nuclear reactor includes a reactor pressure vessel housing plural fuel rods, the reactor pressure vessel having a vessel head. The reactor includes control rods. The control rods are inserted into the reactor between the fuel rods. The control rods are movable to control the power output of the reactor when it is critical, to generate power, and to put the reactor in a shutdown state. The reactor includes control rod drive mechanisms to move the control rods. The control rod drive mechanisms are controllable to release the control rods when a vessel opening operation is performed when the reactor is in the shutdown state and the vessel head is lifted upwards from the reactor pressure vessel so the control rods slide therethrough to remain stationary relative to the fuel rods. The reactor has a monitoring unit to identify whether a control rod is lifting with the vessel head.
