Description
Technical field
The invention belongs to fusion reactor blanket design field, and in particular to a kind of cold ceramic multiplication agent covering of fusion reactor water-helium.
Background technology
Covering is that have tritium propagation, energy conversion and spoke towards the key energy converting member of plasma in fusion reactor
The critical functions such as shielding are penetrated, and are carried out under the multiple physical field collective effects such as high flux neutron irradiation, high temperature, high pressure, high-intensity magnetic field
Fusion reactor material experiment carrier.Cladding technique is that fusion energy moves towards the key technology that application must solve.At present, both at home and abroad
Tens of kinds of covering concepts have been developed.Existing covering can be divided into two species on the physical form of the tritium multiplication agent used from covering
Type：Solid-state multiplication agent covering and liquid multiplication agent covering.Solid-state multiplication agent covering is mainly using positive lithium metasilicate, lithium titanate, zirconic acid
The lithium such as lithium, lithium metaaluminate ceramic bead is as tritium multiplication agent, and therefore, solid-state multiplication agent covering also tends to be referred to as ceramic multiplication agent
Covering.Liquid multiplication agent species mainly has liquid lithium lead, liquid lithium and fluorine lithium beryllium fused salt etc..Due to both may be used using ceramic multiplication agent
The magnetohydrodynamics problem of pressure drop of liquid metal coolant is avoided, heavy corrosion of the liquid metal to structural material is not present again
Problem, and worldwide there is ceramic multiplication agent wider Research foundation and more fully experimental data to support, because
This, ceramic multiplication agent covering has relatively low R＆D risk and good recent application prospect, by domestic and international nuclear fusion field
Extensive concern.
At present, ceramic multiplication agent blanket design is generally using single cooling agent extraction covering heat, cooling agent using helium or
Water, helium or water flow into the first wall runner through header distribution first and the first wall are cooled down, so after entrance enters covering
Miscellaneous part, such as coldplate, dividing plate and side plate are cooled down successively according to certain order afterwards, are finally converged to and are exported and flow out bag
Layer.Existing ceramic multiplication agent covering is disadvantageous in that：（1）Only by the use of water as cooling agent, on the one hand due to the boiling point ratio of water
It is relatively low, make temperature of the water in covering outlet port relatively low, influence conversion efficiency of thermoelectric, reduce fusion power station economy, the opposing party
Face, water flow in the cooling-part runner in breeding blanket, if flow passage structure rupture occurs, water may be with Be contacts
Reaction is learned, hydrogen is produced, adds potential safety hazard；（2）Only by the use of helium as cooling agent, on the one hand due to the cooling performance of helium
It is poor, make the surface heat flow ability to bear of the first wall weaker, limit application of the covering under the conditions of high Fusion power, the opposing party
Face reduces tritium multiplication capacity in breeding blanket because helium is unable to slowing down fast neutron, makes production tritium amount relatively low；（3）Only with helium
Or water Single Medium need to cool down the various parts in covering successively due to cooling agent as cooling agent according to certain particular order,
Make header series more, add the control difficulty of coolant flux distribution uniformity in each coolant flow passages of covering.

Be12Ti mixing ball beds fill Be balls bed as neutron multiplication area as tritium breeding blanket in the cavity not contacted with the first wall.
The both ends of the first described wall are respectively equipped with first order water manifold and second level water manifold, and water enters after covering through the
The distribution of one-level water manifold enters the first wall, then converges to second level water manifold and flows out covering.
The both ends of described coldplate are respectively equipped with first order helium header and second level helium header, and helium enters covering
Enter coldplate by the distribution of first order helium header, then converge to second level helium header.
Described dividing plate and side plate share second level helium header and third level helium header, and helium joins through second level helium
Case distribution enters dividing plate and side plate simultaneously, then converges to third level helium header and flows out covering.
