Tokamak Fusion Reactors
After decades of research, most efforts towards fusion power are based on magnetic confinement fusion with tokamak devices. The ITER machine, in construction since 2010, is the latest such device and it is planned to follow on with a number of demonstration fusion power plants before the final goal of commercial fusion power plants.
Breeder Blanket
The Breeder Blanket is the most critical and complicated component of a fusion reactor because of the dual functions of heat extraction and tritium breeding. Much remains to be done for the decision on the optimum technology and this necessitates a dedicated test facility.
Divertor and Limiter
The divertor is the device which implements the exhaust of the plasma at the end on a confinement cycle. The limiter scraps the edge off the plasma in disruptions and complements the role of the divertor. These components have the highest radiation damage in the tokamak because of the high dose of neutrons they receive.
Superconducting Magnets
Superconducting magnets are the core enabling technology for magnetic confinement fusion reactors. The reliability of the magnets is essential for the operation of a fusion power plant.
