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.

Abstract: A nuclear reactor is provided. The reactor includes a reactor pressure vessel housing plural fuel rods containing fissile material, the reactor pressure vessel having an upper, removable, vessel head. The reactor further includes control rods, each made of a neutron-absorbing material. The control rods are inserted into the reactor through the vessel head and between the fuel rods to control the rate of the fuel rods' fission reaction. The control rods are movable over a normal range of insertion positions relative to the vessel head to control the power output of the reactor when it is critical and generating useful power, and to put the reactor in a sub-critical shutdown state. The reactor further includes control rod drive mechanisms carried by the vessel head and operable to drive the movements of the control rods.
