Abstract

The embodiment of the invention provides a radioactive gas fan and a reactor radioactive gas trapping system, relates to the technical field of nuclear radiation safety, and is used for solving the problem that a fan in the related technology cannot meet the requirement for radioactive gas conveying. The radioactive gas fan provided by the embodiment of the invention comprises an isolation sleeve, a rotor assembly and a magnetic driving device. An air inlet and an air outlet are formed in the isolation sleeve, and the isolation sleeve is made of an anti-radiation material. The rotor assembly is arranged in the isolation sleeve, the magnetic rotor assembly comprises a magnetic rotor and blades, and the magnetic rotor is fixedly connected with the blades. The magnetic driving device is arranged outside the isolation sleeve corresponding to the magnetic rotor, the magnetic driving device is fixed with the isolation sleeve, and the magnetic driving device is used for generating a magnetic field to drive the magnetic rotor to rotate so that the blade drives the radioactive gas in the isolation sleeve to flow from the air inlet to the air outlet. The radioactive gas fan is used for providing power for transmission of the radioactive gas.

Description

technical field [0001] The application relates to the technical field of nuclear radiation safety, in particular to a radioactive gas blower and a reactor radioactive gas capture system. Background technique [0002] At present, the technical route of the accelerator-driven subcritical clean nuclear energy system (ADS) mainly focuses on two fourth-generation fast neutron reactors, namely lead-bismuth cooled and gas-cooled subcritical fast neutron reactors. Among them, in the reactor using the heavy metal lead-bismuth eutectic alloy as the coolant, the lead-bismuth coolant will release radionuclides into the reactor cover gas after being irradiated with neutrons 210 Po, formed 210 Po aerosol. 210 Po is extremely toxic and highly volatile. If the human body is exposed to excessive doses, it will cause serious radiation diseases such as blood cancer and lymph cancer. Therefore to 210 For transmission of Po aerosol, it is important to ensure the airtightness of the transmiss...
