Fusion product comprehensive protection device for Z-hoop condensation polymerization fission energy pile

Abstract

The invention discloses a fusion product comprehensive protection device for a Z-hoop condensation polymerization fission energy pile, and belongs to the field of nuclear reactor devices. The Z-hoop condensation polymerization fission energy pile is provided with a fusion target center and a first wall which is arranged on the periphery of the fusion target center and faces plasmas. The fusion product comprehensive protection device is characterized by comprising an inner gas atmosphere layer, a metal protection cover, an outer gas atmosphere layer and a first wall protection layer; the inner gas atmosphere layer, the metal protection cover, the outer gas atmosphere layer and the first wall protection layer are sequentially arranged from the fusion target center to the first wall facing the plasmas, the inner gas atmosphere layer is formed by inner layer protection gas, the fusion target center and the metal protection cover are filled with the inner layer protection gas, the outer gas atmosphere layer is formed by outer layer protection gas, the metal protection cover and the first wall protection layer are filled with the outer layer protection gas, and the first wall protection layer is arranged on the surface of the inner wall body of the first wall facing the plasmas. The fusion product comprehensive protection device is used for the Z-hoop condensation polymerization fission energy pile, fusion X rays, fusion ions and fusion debris can be absorbed and protected, fusion neutron transmission cannot be influenced, and meanwhile fusion reaction residual deuterium tritium fuel is easily recycled through the fusion product comprehensive protection device.

Description

technical field [0001] The invention belongs to the field of nuclear reactor devices, in particular to a protective device for a Z-pinch fusion fission hybrid energy reactor. Background technique [0002] Z-Pinch-Driven Fusion-Fission Hybrid Power Reactor (Z-FFR) uses Z-pinch to drive a large number of neutrons generated by inertial confinement fusion (ICF) to drive subcriticality The release of energy by fission reactor is a new energy that can effectively deal with future energy crisis and environmental and climate issues. Z-FFR requires a fusion target chamber (Fusion Chamber) to provide the necessary environment for fusion generation, while containing fusion products and providing fusion safety protection functions. The Z-pinch fusion release energy of the energy application scale is about 1~3GJ per pulse (1GJ=10 9 J), where 80% of the energy is carried by fusion high-energy neutrons and used to drive subcritical fission stacking energy. The remaining 20% ​​of the ene...

Problems solved by technology

[0008] The Z-FFR fusion X-ray energy is about 200MJ~600MJ, and the aerosol at 1000~2000Pa cannot completely absorb it.

Although increasing the inflation pressure and aerosol concentration can absorb all the X-ray energy, it will also generate extremely strong shock waves in the target chamber, posing a serious threat to the safety of the first wall

[0009] Also, In-Zinerator's aerosol shielding solution is not very good against fusion debris (Debris)
