Abstract

The invention relates to a combined type helium gas filtering sampling device for a gas cooled reactor and an installation method of the device. The combined type helium gas filtering sampling device is characterized by comprising a sleeve, at least two filter assemblies which are spaced along the axial direction and are fixed on the inner wall of the sleeve, and at least one molecular sieve assembly fixed between the two adjacent filter assemblies. The filtering sampling device provided by the invention adopts a sandwich combined type structure with the filter assemblies-the molecular sieve-the filter assembly, can fully filter fission product particles and graphite dust with different types and sizes carried by helium from a vapor generator, and can fulfill the purposes of multistage filtering, full deposition and adsorption of the fission product particles and graphite dust.

Description

technical field [0001] The invention relates to reactor engineering equipment, in particular to a combined helium filtering and sampling device for a gas-cooled reactor and an installation method thereof. Background technique [0002] The high temperature gas-cooled reactor nuclear power plant demonstration project (HTR-PM) of Huaneng Shandong Shidaowan Nuclear Power Plant is built on the technical basis of the 10 MW high temperature gas-cooled experimental reactor independently designed, constructed and operated by Tsinghua University with independent intellectual property rights The 200-megawatt high-temperature gas-cooled reactor nuclear power plant demonstration project is the first high-temperature gas-cooled reactor commercial demonstration power plant in China. The high-temperature helium filter sampling device of the high-temperature gas-cooled reactor is an important part of the process radiation monitoring system. It is mainly used to collect the fission products i...
