Abstract

The invention discloses a detector assembly dismounting control system and a corresponding control method, and further provides a nuclear reactor detector assembly dismounting system composed of a nuclear reactor detector assembly dismounting device and a corresponding nuclear reactor detector assembly dismounting control system. The nuclear reactor detector assembly dismounting device is used forpulling out the high-radioactivity detector assembly at the end of the service life from a channel of an upper reactor internals guide structure, placing the high-radioactivity detector assembly intoa special container after complete continuous actions such as shielding, shearing and winding, and transferring the high-radioactivity detector assembly to a specified treatment place. The purposes of continuous operation, safety and high efficiency are achieved. The corresponding detector assembly dismounting control system can achieve control operations such as positioning, grabbing, shearing (shielding), winding, transferring and the like.

Description

technical field [0001] The invention relates to the technical field of dismantling of reactor equipment, in particular to a control system and a control method for dismantling a nuclear reactor detector assembly. Background technique [0002] The instruments used in the core measurement system in the second-generation and second-generation pressurized water reactor nuclear power plants are divided into instrument thermocouples for temperature measurement and instrument neutron flux detectors for neutron flux measurement. The thermocouple is introduced from the top cover of the pressure vessel, guided by the thermocouple column assembly, and positioned at the specified measuring point position, and the lower end of the thermocouple is located at the core outlet of the upper core plate. The neutron flux detector is introduced from the bottom head of the pressure vessel, guided through the instrument casing and finger casing when necessary, and enters the guide pipe inside the ...
