The two main plasma-wall interaction problems in tokamaks are the erosion of the divertor plates and the accumulation of tritium and dust in the vessel. The conventional solution to these problems is to stop machine operation to replace the worn divertor plates and to remove the dust and tritium. The conventional divertor design is also subject to a potentially catastrophic loss of coolant due to a break in the water-cooling lines just below the plasma-facing surface. This invention could solve these problems by replacing the conventional divertor by a set of moving divertor plates.
