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)

Embodiment 1

[0054] refer to figure 1 As shown, a comprehensive protection device for a Z-pinch fusion-fission hybrid energy reactor, the Z-pinch fusion-fission hybrid energy reactor is provided with a fusion bullseye 3 and its peripheral plasma-facing first wall 8, including a fusion bullseye 3 From the outside to the first wall 8 facing the plasma, the inner gas atmosphere layer 4, the metal protective cover 5, the outer gas atmosphere layer 6 and the first wall protection layer 7 are arranged in sequence, and the inner gas atmosphere layer 4 is filled with fusion The inner protective gas between the bullseye 3 and the metal shield 5 is formed, and the outer gas atmosphere layer 6 is composed of the outer protective gas filled between the metal shield 5 and the first wall protective layer 7, and the first wall protective layer 7 It is arranged on the inner wall surface of the first wall 8 facing the plasma. The inner protective gas is Ar gas with a pressure of 1000Pa, and the outer prot...

Embodiment 2

[0056] This embodiment is basically the same as Embodiment 1, the difference is that the inner protective gas is Ar gas with a pressure of 500Pa, and the outer protective gas is Ar gas with a pressure of 500Pa. The metal protective cover is made of Al, with a radius of 50 cm and a wall thickness of 0.25 mm. The protective layer of the first wall is a W-10% Re alloy facing the inner wall surface of the first plasma wall, and the coating thickness is 0.2mm. Under the condition of 1.5GJ fusion energy release, the final protection result is calculated by using the radiation hydrodynamic model calculation program: the radiation energy density on the inner surface of the first wall is about 50J / cm without protection 2 down to 0.015J / cm 2 , peak radiation current power density 7W / cm 2 , the impact strength received by the first wall at the same time is 0.20 MPa, both of which are far less than the safety limit of the first wall; the fusion energy fragments together with the metal p...

Embodiment 3

[0058] This embodiment is basically the same as Embodiment 2, the difference is that the inner protective gas is Ar gas / Al aerosol with a pressure of 100Pa, and the outer protective gas is Ar gas / Al aerosol with a pressure of 250Pa. The metal protective cover is made of Al metal with a radius of 60cm and a wall thickness of 0.2mm. The protective layer of the first wall is a W-10% Re alloy facing the inner wall surface of the first plasma wall, and the coating thickness is 0.2mm. Under the condition of 1.5GJ fusion energy release, the final protection result is calculated by using the radiation hydrodynamic model calculation program: the radiation energy density on the inner surface of the first wall is about 50J / cm without protection 2 down to 0.06J / cm 2 , Peak radiation current power density 42W / cm 2 , the impact strength received by the first wall at the same time is 0.25 MPa, both of which are far less than the safety limit of the first wall; the fusion energy fragments t...

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...
