The invention provides a hollow radioactive inclusive fuel containing burnable poison and a preparation method and application thereof. The hollow radioactive inclusive fuel containing burnable poison comprises a hollow fuel area and a fuel-free protective layer wrapping the periphery of the fuel area. The hollow fuel area comprises a base body, fuel elements and burnable poison, wherein the fuel elements and the burnable poison are distributed in the base body. The fuel element is an isotropic coated fuel particle, and the burnable poison is an isotropic coated burnable poison particle. According to the invention, high-compactness and high-safety reactor fuel radioactivity containment can be realized, radioactive products, especially fission gas, are not released into the environment in an accident, a fission place is provided for long-period stability of a miniature nuclear power source reactor core, the radioactive fission products are effectively restrained in the fuel, and the safety of the reactor is im
