Abstract

The invention relates to a sleeve type helium temperature-control sediment sampling device applied to a high-temperature gas cooled reactor. The sampling device is characterized by comprising a sleeve, a core rod which is fixed inside the sleeve and extends along the axial direction, a plurality of temperature control units which are sequentially fixed on the outer wall of the sleeve at intervals along the axial direction, a plurality of water delivery pipe sections for communicating every two adjacent temperature control units, as well as a water inlet and a water outlet which are respectively connected with the two temperature control units at the outmost sides. The temperature-control sediment sampling device is capable of implementing the certain temperature control on a high-temperature helium environment generated by a steam generator in the whole sedimentation length, so that during the continuous cooling process of high-temperature helium, sedimentable fission product particles with different types, and graphite dust within different particle size ranges, which are carried in the high temperature helium, are gradually sedimented and adsorbed onto the sleeve and the core rod through a certain temperature gradient, and therefore, the follow-up measurement and analysis can be effectively implemented.

Description

technical field [0001] The invention relates to reactor engineering equipment, in particular to a casing type helium temperature-controlled deposition sampling device applied to a high-temperature gas-cooled reactor. Background technique [0002] The Nuclear Research Institute of Tsinghua University built and operated a 10MW high temperature gas-cooled experimental reactor (HTR-10) in 2000. The experimental reactor is a high-temperature gas-cooled reactor that uses graphite matrix-coated granular spherical fuel elements and an all-graphite core structure, and uses high-purity helium as a coolant. Its main construction purposes include demonstrating the safety of modular high-temperature gas-cooled reactors. characteristics and form a scientific research base to carry out relevant experimental research, etc. [0003] The high-temperature helium filter deposition sampling device of the high-temperature gas-cooled reactor is an important part of the process radiation monitorin...
