Device and method for producing isotope by using heavy water reactor observation hole

The invention provides a device for producing isotopes by using a heavy water reactor observation hole. The device comprises a guide pipe, a target lifting basket, a target recycling pipe, a driving mechanism, a shielding box and an air extractor, the guide pipe is arranged in an observation hole in the top of the heavy water reactor and is sealed below the sealing cover; the target lifting basket is connected with the driving mechanism; one end of the target recycling pipe extends into the guide pipe, the other end of the target recycling pipe penetrates out of the sealing cover to be connected with a target conveying pipe, and the target conveying pipe is connected with the shielding box; the air extractor is connected with the sealing cover through a gas transmission pipe, and the shielding box is connected with the gas transmission pipe. According to the invention, the dosage of the target in the out-of-reactor transfer process can be reduced, so that the shielding requirement is greatly reduced. 本发明提供了一种
