Abstract

The invention relates to the technical field of built-in control rod driving, and provides a built-in control rod driving line assembling method. According to the method, a control rod driving shaft is mounted in a buffer cylinder; the lower end of the control rod driving shaft penetrates through the buffer cylinder and is connected with a cross-wing control rod; a driving line guide cylinder is mounted on a reactor internal structure, then a rod position measuring component and a driving mechanism component are assembled to form a driving line assembly, then the driving wire assembly is hoisted into the driving line guide cylinder, and a combined valve component is mounted on the rod position measuring component. The assembly operation is simple and convenient, the efficiency of loading and unloading work and maintenance work is improved, the safety and reliability of the installation operation process can be guaranteed, and then safe and reliable operation of the built-in control roddrive line after assembly is guaranteed.

Description

technical field [0001] The invention relates to the technical field of built-in control rod driving, in particular to a method for assembling a built-in control rod driving line. Background technique [0002] In the built-in control rod driving technology, the driving mechanism needs to be placed in the high temperature, high pressure and irradiation environment in the reactor pressure vessel, and three hydraulic cylinders are used to lift, transfer and clamp in order to drive the transmission and clamp two sets of pins The claw mechanism moves to realize the functions of step-up, step-down and drop of the control rod. [0003] Based on the working principle of the driving mechanism and the characteristics of the small integrated water reactor control rod drive line, the built-in control rod drive line is required for safe and reliable assembly and disassembly operations on the integrated small water reactor. However, the loading and unloading method of the built-in control...
