Problems solved by technology

[0003] In the prior art, the CARR reactor (China Advanced Research Reactor) is usually used for isotope production, but the core of the CARR reactor is equipped with isotope production channels and various channels to extract neutron beams for different research needs. The experiments lead to a more complex core structure, lower isotope production efficiency, and fewer types of isotopes that can be produced

Abstract

The invention provides a reactor core. The reactor core comprises: a core grid that includes a plurality of unit grids connected with each other; a fuel assembly, which is arranged in the unit grids and provides fuel for fission reactions; a control part, which is arranged in the unit grids and is used for controlling the reactivity of the fission reactions; a reflection assembly, which is arranged in the unit grids and is used for reflecting neutrons generated by fission reactions so as to increase the neutron fluence rate of the reactor core; and production assemblies, which are disposed inthe cell grid, receive neutron irradiation and generate radioisotopes. The core is configured to include at least two production assemblies for generating different radioisotopes. The reactor core hasthe characteristics of simple structure, multiple types of produced isotopes and high efficiency.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of nuclear reactors, in particular to a core. Background technique [0002] Isotope production is one of the important uses of nuclear reactors. The use of nuclear reactors for isotope production requires a high maximum thermal neutron fluence rate per unit power of the core and a large space for effective neutron utilization. [0003] In the prior art, the CARR reactor (China Advanced Research Reactor) is usually used for isotope production, but the core of the CARR reactor is equipped with isotope production channels and various channels to extract neutron beams for different research needs. The experimental results in complex core structure, low isotope production efficiency, and fewer types of isotope can be produced. Contents of the invention [0004] In order to overcome the deficiencies in the above prior art, the object of the present invention is to provide a core with simpl...
