Abstract

The invention belongs to a reactor overhaul device, and in particular relates to a device for treating a broken root of a pressure hull of a reactor control rod driving mechanism. The device consists of a hydraulic station, a special boring and drilling handpiece and a boring and drilling handpiece bracket. The problem that the pressure hull is closely hinged to a top cover component pipe seat during cover opening overhaul of a reactor is solved; and on the premise that the top cover component pipe seat of a reactor pressure container is not damaged, broken roots of the pressure hull and a rotor component, which are retained in the pipe seat, are taken out, so that the broken root of the pressure hull of the reactor control rod driving mechanism can be treated, and the original performance of a top cover component of the reactor is recovered. By the device, the reactor overhaul efficiency is improved, and the safety running of the reactor control rod driving mechanism can be technically guaranteed.

Description

technical field [0001] The invention belongs to a reactor overhauling device, in particular to a device for treating roots of a pressure casing of a driving mechanism of a reactor control rod. Background technique [0002] The reactor pressure vessel top cover assembly tube socket is one of the key components of the reactor. It plays a very important role in supporting the control rod drive mechanism, containing the reactor core, bearing the pressure boundary of the primary circuit, and preventing the spread of radioactive substances. However, in the process of reactor decapping and maintenance, it is easy to cause the control rod drive mechanism pressure casing part and the top cover assembly tube seat to be seized, resulting in failure to disassemble normally. If it is not taken out, the decapping and maintenance of the reactor cannot be carried out. The safe operation of the reactor cannot be guaranteed. [0003] As one of the key components of the reactor, the top cover...
