description The invention discloses an unlocking and locking control method and an unlocking and locking device for a reactor core pressure relief explosion valve controller, and belongs to the technical field of nuclear reactor protection digital instrument control. A plurality of field signals and manual operation signals representing working conditions of a nuclear reactor field are detected through the unlocking and locking device, and under the normal working condition of the nuclear reactor, a locking signal is output to enable the explosion valve controller to be in a locking state and an ignition signal to be invalid, so that the explosion valve controller is prevented from igniting and breaking a valve by mistake, and the risk of false triggering of the explosion valve controller is reduced; and under the accident working condition, an unlocking signal is output, so that the explosion valve controller quickly enters an unlocking state, an explosion valve ignition signal can be normally provided, the reliability
