Problems solved by technology

Due to the strong radioactivity of coated fuel particles after irradiation, they need to be operated in a hot chamber, and personnel cannot approach them. At the same time, the diameter of coated fuel particles after irradiation is small, generally 0.8-1mm, so special pick-up equipment is required , In ad

Abstract

The invention relates to the nuclear technological field and particularly relates to an automatic sorting device for irradiated particles. The device comprises a base, a particle automatic picking unit, a particle collection unit and a particle measuring unit. The particle collection unit comprises a sample bottle and a lofting bottle which are arranged on the base. The measuring unit comprises a shielding cavity and a measuring instrument, and the measuring instrument is opposite to the shielding cavity. The particle picking unit comprises a vacuum suction pen and a vacuum pump. The vacuum suction pen is fixed on the base movably and is arranged vertically, and a suction opening of the vacuum suction pen is downward. The vacuum pump is connected with the suction opening through a pipe, the vacuum pump pumps air in the vacuum suction pen through the suction opening to control the suction opening to suck samples to be detected. A control unit is further arranged. By means of the device, automatic grabbing, detection, classification and putting of radiated coated fuel particles can be achieved, and the device is applicable to damage detection and analysis of high-radioactivity irradiated coated fuel particles.

Description

technical field [0001] The present invention relates to the field of nuclear technology, in particular to an automatic particle sorting device after irradiation, and more specifically to an automatic sorting device with the functions of automatic suction and non-contact automatic detection of irradiated nuclear fuel coated particles. select device. Background technique [0002] The spherical fuel element is an important guarantee for the inherent safety of the high temperature gas-cooled reactor nuclear power plant. The TRISO (English name: Tri-structural iso-tropic, English abbreviation: TRISO) type coated fuel particles used in it is the It is the first barrier to prevent the release of fission products. The spherical fuel element used in my country's pebble bed high-temperature gas-cooled reactor has spherical ceramic-coated particles dispersed in the graphite matrix of the fuel area, and the spherical nuclear fuel uranium dioxide (molecular formula: UO 2 ) core, loose ...
