Abstract
The invention discloses a superconducting magnetic confinement fusion reactor fast thermal neutron coupled water-cooled tritium production solid cladding layer. According to the invention, pressure water is used as a coolant. The structure of the cladding layer comprises a plurality of tritium production proliferative zones formed by mixing tritium production materials and neutron multiplication materials. The tritium production proliferative zones are respectively filled by using binary pebble bed proliferation agents and multiplication agents. Different zones are obtained by dividing by using radial reinforcing partition plates and cooling plates comprising coolant channels. Pressure water is distributed by a header in the cladding layer, flows through the proliferative zones at the back part of the cladding layer, and is heated to a saturated boiling state; and the pressure water is collected by a middle header and is distributed to the proliferative zones on the front part of the cladding layer; the water is continued to be heated until turned into dry saturated steam; the steam enters a first wall coolant path, and is heated to superheated steam. The superheated steam can lead out high heat flux density at the wall, and at the same time the moderation effect of the coolant to high-energy neutrons from outside a first wall is reduced.
Description
Technical field
The present invention relates to nuclear fusion engineering field, specifically a kind of superconducting magnetic constraint fusion reactor fast thermal neutron coupling water-cooled produces tritium solid blanket.
Background technology
Controllable thermonuclear fusion can represent future and the hope of mankind's energy.Development history as magnetic confinement fusion heap (tokamak device) of one of controllable thermonuclear fusion two kinds of implementations has had more than 50 year, and the International Thermal-Nuclear Experimental Reactor (ITER) that current countries in the world are established jointly in France is expected as the through engineering approaches target of fusion energy generating of marching toward is taken a firm foundation.Covering is the key energy converting member of fusion facility, and its major function comprises: 1) tritium propagation, produces the tritium needed for the fusion reaction of vacuum chamber core, and the tritium of implement device is controlled oneself and run; 2) the high energy particle energy conversion that fusion reaction obtains is the heat energy being more convenient for utilizing by energy conversion; 3) radiation shield, stops the diffusion of radioactive product in covering, contains radiomaterial to carry out aftertreatment.Therefore, covering is that fusion energy moves towards one of gordian technique carrier applied.
Blanket design needs to select suitable cooling medium and tritium multiplication agent.The cooling medium that the fusion reactor blanket and researched and developed in the world at present adopts mainly contains water, helium and liquid metal (comprising fused salt), and the tritium multiplication agent of employing mainly contains the Li of solid-state ceramic
2o, Li
4siO
4, Li
2tiO
3deng and LiPb, Li, FLiBe etc. of liquid state.In conjunction with cooling medium and multiplication agent two aspect, international existing several large class main flow covering concept comprises helium cooled solid blanket, water-cooled solid blanket, the cold liquid blanket of helium, self cooling fused salt covering etc.Several typical fusion reactor blanket design example as, the plumbous liquid blanket WCLL of the helium cold ball bed solid blanket HCPB that Europe proposes, water-cooled lithium, the plumbous two cold liquid blanket ARIES-ST of the lithium that the U.S. proposes, the plumbous self cooling liquid blanket ARIES-AT of lithium etc.But as the helium of one of the conventional candidate's cooling medium of fusion reactor blanket, because its specific heat capacity is relatively low, cooling power is general, is difficult to realize the abundant cooling to covering.In order to improve helium convection transfer rate thus the first wall is born up to MW/m
2the heat flow density of the order of magnitude derives, and the flow velocity of helium in covering needs to reach about 100 m/s, and this proposes harsh requirement to the performance of helium circulator and Project Realization.And liquid metal multiplication agent is owing to existing magnetohydrodynamics (MHD) effect, the induction current that its flowing produces and magnetic field result in significant resistance to flow and flow instability, add the Project Realization difficulty of covering.The fusion reactor water-cooled solid blanket that Japan proposes based on commercial presurized water reactor (PWR) cooling medium operating condition standard designs, widespread use ripe presurized water reactor technology and index, reduce development difficulty, and avoid the inherent shortcoming of aforesaid helium coolant and liquid multiplication agent covering.But the water coolant under 15MPa operating pressure keeps liquid in covering total travel, covering outlet coolant temperature is no more than the temperature of saturation water under this pressure, therefore the available heat quality of covering is lower.And light-water is good neutron moderator, the aqueous water in the first wall coolant channel has strong slowing down effect to the high-energy neutron that the zero energy produced from the outer fusion reaction of the first wall is 14MeV.In this case, major part neutron before the product tritium breeding blanket arriving covering back zone just by slowing down and by product tritium multiplication agent and neutron multiplication agent reaction absorb, its result causes the tritium multiplication capacity of covering back zone not enough thus affects the raising of the tritium multiplicaiton factor TBR of whole covering.In addition, uneven Neutron flux distribution also causes covering power skewness thus produces extra thermal stress to covering inner structure.
