摘要： The present invention provides a control rod driving mechanism (100) with safety protection function, including a rod position detector assembly, a pressure-resistant housing assembly, a claw assembly, a driving lever assembly, a coil assembly and a safety protection device. The safety protection device includes a fixing magnetic pole, a locking coil, a spring, a movable armature, a claw and a transition support sleeve, wherein a sealing housing is coupled to the transition support sleeve via the fixing magnetic pole, the transition support sleeve is coupled to the claw assembly, the movable armature is slidably arranged in the transition support sleeve. One end of the spring elastically abuts against the movable armature, and the other end of the spring elastically abuts against the fixing magnetic pole or the transition support sleeve. The claw is mounted on the transition support sleeve and linked with the movable armature, and the driving lever assembly penetrates the transition support sleeve and the fixing magnetic pole. The locking coil is mounted on the coil assembly and the movable armature slides axially such that the claw pivotally swings for engaging with or releasing from the driving rod assembly, to achieve a reliable safety protection function and realize safe shutdown of the reactor

摘要： The present invention provides nuclear power plant intelligent technical specification method and system. The nuclear power plant intelligent technical specification method includes the steps of: obtaining a predetermined operating signal and a device state of a nuclear power plant by means of a nuclear power plant KNS system (S101); determining an operating condition of the nuclear power plant according to the device state (S102); determining whether to trigger a predetermined event according to the operating signal, the operating condition and a preset threshold (S103); upon determining to trigger a predetermined event, activating the predetermined event and triggering processing measures and supervision requirements corresponding to the event, and simultaneously starting a timer to remind an operator to complete the processing measures required by specification within a specified time (S104). The present nuclear power plant intelligent technical specification method and system may intuitively reflect safety indicators of the nuclear power plant, and help an operator to handle the event quickly, so that the safety of the nuclear power plant is improved, the economy and the availability of the nuclear power unit are improved, and the market economy value is high.
