Irradiation Experimental Device for Pulsed Reactor

Abstract

The invention discloses an irradiation experimental device for a pulse reactor. A radial duct is formed in the pulse reactor. The radial duct comprises a duct outlet. A neutron trap is arranged inside the radial duct; a shielding body is arranged outside the radial duct; and a passing hole is formed in the shielding body. The irradiation experimental device comprises a movable shielding cover, a shielding storage rack, a double-screw synchronous drive mechanism and an elevator, wherein the shielding storage rack is arranged at a position, which avoids an area of the passing hole, above the shielding body; the shielding storage rack is used for placing shielding irradiation cavities of different specifications; the elevator comprises an elevator car; and when the elevator car is located in the bottom-most layer, an opening of the elevator car is opposite to the duct outlet. According to the irradiation experimental device disclosed by the invention, the double-screw synchronous drive mechanism is used to drive the elevator car to move, so that automatic transfer and storage can be achieved in the shielding storage rack and the duct outlet, thereby achieving replacement and storage of a plurality of sets of experimental devices in a small experimental space, and also ensuring the radiation protection safety of laboratory personnel.

Description

technical field [0001] The invention belongs to the field of reactor application technology and radiation effect research, in particular to a storage, replacement and positioning device for a reactor neutron source used in a displacement damage effect experiment platform, in particular to an irradiation experiment device for a pulse reactor. Background technique [0002] There are a large number of high-energy protons, electrons and heavy ions in the space radiation environment. These high-energy protons, electrons and heavy ions have displacement damage effects on spacecraft electronic components, leading to performance degradation and failure of spacecraft electronic systems. The reactor neutron source is the current domestic Neutron sources are commonly used for external research and assessment of the displacement damage effect of spacecraft electronic components. The space displacement damage effect is one of the key points in the evaluation of the on-orbit reliable oper...

Problems solved by technology

[0008] 3. There are 3 shielded irradiation chambers developed to meet different experimental needs. The existing radial tunnel shielding room cannot place so many shielded irradiation chambers at the same time. Therefore, an automated mechanical device must be used to replace the shielded radiation chamber
