Problems solved by technology

At present, the main method of producing carbon 14 in the world is to place targets for the production of carbon 14 in reactors with high neutron flux rates, and obtain them through neutron capture reactions. Domestic carbon 14 is mostly produced in experimental reactors , but the output is small and cannot sustainably produce

Abstract

The invention belongs to the technical field of radionuclide production, and particularly relates to a carbon 14 target rod placed in a square assembly in a nuclear reactor. The carbon 14 target rod is arranged in the square assembly of the nuclear reactor and used for producing a carbon 14 material, and the square assembly is used for arranging a burnable poison rod. The carbon 14 target rod comprises a sealed cylindrical target rod (2), and aluminum nitride powder is loaded in the target rod (2). According to the carbon 14 target rod placed in the square assembly in the nuclear reactor, high-quality carbon 14 with enough yield can be produced, the heating power of the target rod (2) is extremely low, the highest temperature of a coolant of the reactor core cannot exceed a limit value, the safety of the reactor core is not influenced, operating parameters are hardly changed, and moreover, all types using square assemblies as fuel in China or internationally can be applied.

Description

technical field [0001] The invention belongs to the technical field of radionuclide production, in particular to a carbon-14 target rod placed in a square assembly in a nuclear reactor. Background technique [0002] At present, there are more than 30 kinds of main radionuclides produced by reactors, among which Co-60 (irradiation source) is the main radionuclide for industrial use, which is mainly produced by CANDU heavy water reactor in Canada, and the Qinshan Phase III reactor in my country has Co-60 -60 production lines. In terms of medical use, the variety and output of domestically produced radionuclides are very limited, and they mainly rely on imports. Their prices have doubled, and the supply of medical radionuclides has been in short supply. [0003] Carbon 14 is a radioactive isotope of carbon. It is widely used in medical and biomedical industries such as breath testing and labeling compounds. The annual global consumption is about 2,000 curies. At present, only R...
