Abstract

The invention relates to the technical field of nuclear power station rod control systems, in particular to a nuclear power station RGL system control rod group control method. The method comprises the steps that in the RGL test process, if monitoring that a control rod set is located at a non-required rod position due to the fact that a logic cabinet breaks down, a control panel rapid lifting and inserting device is installed in an RGL system to be in communication connection with a power supply cabinet, and the power supply cabinet is controlled by the control panel rapid lifting and inserting device to release the moving locking state of the control rod set; a control instruction is sent to a power supply cabinet through a control panel rapid lifting and inserting device, so that the power supply cabinet controls a control rod group corresponding to a faulty rack to move to a required rod position to eliminate a first group I0 of a generator set, thereby avoiding a retreating limiting behavior of the generator set, avoiding economic loss, and reducing unit loss and manpower consumption. Meanwhile, nuclear power station operators have sufficient time to eradicate faults of the RGL system, and human errors caused by time pressure are reduced.

Description

technical field [0001] The invention relates to the technical field of nuclear power plant rod control systems, in particular to a method for controlling a control rod group of a nuclear power plant RGL system. Background technique [0002] The generator sets in nuclear power plants have requirements for the position of the control rod group in the reactor core in different states. For example, during the daily full power operation, each group of control rod groups requires a rod position of 225 steps; in RGL (rod control rod position system) during the test process, the nuclear power plant operators need to escort the whole process of the test, because when the control rod group is not in the required rod position due to RGL system failure, the generator set will be withdrawn after 1 hour, and the generator set will start to drop according to the regulations. Power, that is, the reduction of power generation, will cause great economic losses and certain equipment damage. T...
