Title:
REACTOR CORE MEASUREMENT INSTRUMENT GUIDE ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2024/011781
Kind Code:
A1
Abstract:
Disclosed in the present invention is a reactor core measurement instrument guide assembly, comprising: a bottom plate, which is arranged in a cavity defined by means of a top cover of a reactor pressure vessel, wherein an upper side of the bottom plate is provided with instrument guide pipes and instrument guide pipe supporting columns for supporting the instrument guide pipes, and rigid sleeves are provided on a lower side of the bottom plate; and support columns, which are arranged in an upper in-reactor member of a reactor, wherein the support columns are each provided with an accommodating chamber corresponding to the rigid sleeves, and the rigid sleeves can vertically move along an axis relative to the upper in-reactor member, so as to be inserted into or pulled out of the corresponding accommodating chamber. Compared with the prior art, the reactor core measurement instrument guide assembly of the present invention is provided with the rigid sleeves, wherein each of the rigid sleeves has a large diameter and a relatively thick wall, the rigid sleeves have an ideal rigidity, and when a reactor core measurement instrument is inserted downwards, the reactor core measurement instrument can be accurately aligned with the support columns in the upper in-reactor member, thereby ensuring that the reactor core measurement instrument can be successfully inserted into the support columns in the upper in-reactor member.
