Hydrogen Recycling At Plasma Facing Materials

One Of The Most Important Issues In The Construction Of Future Magnetic Confinement Fusion Machines Is That Of The Materials Of Which They Are Constructed, And One Of The Key Points Of Proper Material Choice Is The Recycle Of Hydrogen Isotopes With Materials At The Plasma Face. Tritium Machines Demand High Safety And Economy, Which In Turn Requires The Lowest Possible T Inventory And Smallest Possible Permeation Through The Plasma Facing Materials. The Recycle Behaviour Of The In-vessel Components Must Also Be Known If The Plasma Reaction Is To Predictable And Controllable, And Finally, The Fuel Cycle And Plasma Operating Regimes May Be Actively Controlled By Special Materials And Methods.
