Description

technical field

[0001] The invention relates to the field of nuclear industry, in particular to a control rod driving mechanism and a control rod driving method. Background technique

[0002] During the operation of the reactor, it is necessary to control the work of the control rods, which involves the insertion, withdrawal and refueling of the control rods. For the sake of safety, the work of inserting, withdrawing and refueling of the control rods cannot be directly carried out manually. For the sake of work efficiency, it is not a good choice to use manual methods to insert, extract, and refuel the control rods. Therefore, there is a need for a device capable of inserting, withdrawing, refueling and other operations on the control rod. Contents of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a control rod driving mechanism with simple structure, low manufacturing difficulty and reliable oper...
