摘要： The present invention relates to the technical field of reactor system equipment and provides a control rod control device and a reactor. The control rod control device includes: an upper driving rod comprising an accommodating cavity in an interior of the upper driving rod; a lower driving rod; a trigger assembly including a trigger mechanism and a trigger pin, the trigger mechanism configured to keep the trigger pin in a locked state, the trigger mechanism operable to trigger displacement of the trigger pin when the upper drive rod moves upward with a certain acceleration; and a support member arranged at a junction between the upper driving rod and the lower driving rod and linked with the trigger pin. The present invention is used for automatically disconnecting the connection between the driving rod and a control rod assembly in the event of a rod ejection accident condition, so that the out-of-control rejection of a control rod is avoided, which ensures that a large amount of positive reactivity will not be introduced into the reactor core in a short period of time, reduces the probability of cladding damage, and improves the safety of the reactor.
