Abstract

The invention discloses a fuel element, a high-temperature gas cooled reactor and a high-temperature gas cooled reactor system, relates to the technical field of high-temperature gas cooled reactors,and aims at solving the technical problem that dust pollution is easily generated when an existing fuel ball is not stopped for refueling. The fuel element provided by the invention comprises a plurality of fuel boxes containing fuel elements, each fuel box adopts a regular tetrahedron structure, a regular quadrangular prism structure or a regular hexagonal prism structure, the fuel elements adoptTRISO coated granular fuel, and a plurality of holes are formed in the side wall of the fuel box.

Description

technical field [0001] The invention relates to the technical field of high-temperature gas-cooled reactors, in particular to a fuel element, a high-temperature gas-cooled reactor, and a high-temperature gas-cooled reactor system. Background technique [0002] High-temperature gas-cooled reactors use coated particulate fuel and graphite as a moderator. The core outlet temperature can reach 850-1000°C, or even higher; nuclear fuel generally uses high-enriched uranium dioxide, and some use low-enriched uranium dioxide; And prismatic high-temperature gas-cooled stacks. [0003] Specifically, in the prior art, once the fuel balls are put into the core, their residence time and moving route in the pile are completely out of people's control, and the void ratio between adjacent balls is completely random and uncontrollable, so that For the area near a certain point in the core, the heat generated by the fuel balls and the heat exported by helium are not only unpredictable, but a...
