Abstract
The invention discloses a modular type fusion-and-fission hybrid reactor cladding fuel section based on Z pinch driving. A fusion target driving mechanism is arranged at the top end of each fuel section body, a target recycling area is arranged at the bottom end of each fuel section body, the fuel section is divided into the multiple fuel section bodies in the annular direction, and each fuel section body is axially provided with three independent modules which include the trapezoid-table upper-end module located at the upper portion, the cuboid middle module located in the middle and the trapezoid-table lower-end module located at the lower portion. Cooling water pipes of the upper-end modules are arranged to be in transverse-S shapes, cooling water pipes of the lower-end modules are arranged to be in transverse-S shapes, cooling water pipes of the middle modules are axially arranged, an engineering passage is arranged at the outer end of the fuel section and is in a vertically-through type, and the upper end and the lower end of the engineering passage are communicated with the middle section of a double-layer safe shell. Based on Z pinch inertial confinement fusion driving, the defects of the complex structure, the limited available space and the poor hybrid reactor cladding engineering reliability caused by a Tokamak magnetic confinement device are overcome, and long-time stable energy output is achieved.
Description
technical field [0001] The invention relates to a cladding fuel area of a modular fusion and fission mixed reactor based on Z pinch drive, and belongs to the technical field of fusion and fission mixed reactors. [0002] Background technique [0003] The fusion-fission hybrid reactor uses the high-energy neutrons produced by the deuterium-tritium fusion reactor to drive the subcritical envelope. The fusion neutrons in the envelope are used to cause fission, produce fissile fuel or transmutate radioactive nuclear waste, and at the same time breed tritium to fuel the fusion reactor. Provide enough tritium. The main purpose of the mixed energy reactor is commercial power generation. The fuel in the cladding is fission reactor spent fuel or natural uranium to achieve higher energy amplification and improve the energy balance of the fusion system. [0004] The fusion-fission hybrid reactor is based on the fact that the fusion reaction is neutron-rich (referring to neutrons th...
