Effectively reduce irradiation damage of the Fusion Neutron to solid structure material；It is cyclically updated by the real-time online for flowing liquid lithium, can
To avoid the occurrence of corrosion and the service life problem of similar solid material；Can also be effectively additionally by being cyclically updated for liquid lithium
The foreign particle in plasma is adsorbed and taken away, low recycling operational mode is realized, high constraint plasma discharge is obtained, it is right
Realize that the steady-state operation of plasma is very helpful.
But to magnetic confinement fusion heap, the realization of liquid lithium divertor also has many technical barriers to need solution.Firstly the need of
The problem of solution be how in the environment of fusion reactor high-intensity magnetic field set up can completely cover solid bottom wall and stably, thickness it is uniform
Film stream flowing.Two key factors wherein influenceed are：The wetability and strong magnetic field gradient of liquid lithium and solid bottom wall.It is existing
Test result indicates that when the wetability of liquid lithium and solid bottom wall is very poor, liquid lithium free surface flow is easily punctured into small stream shape
Flow and solid bottom wall can not be completely covered.Following its bottom wall solid material of magnetic confinement fusion heap liquid divertor is deposited with liquid lithium
The problem of wetability is bad, therefore how to realize that liquid lithium film stream is uniform and stable in the case where wetability is bad and cover completely
Lid solid bottom wall material turns into the key issue for needing to solve.
