Particular aspects inherent to tritium use for fusion reactors

Particular aspects and difficulties inherent to tritium use for Fusion Reactor are numerous and sometimes difficult to solve. Nevertheless, important programs have been undertaken worldwide and concrete results already obtained in the various areas of a Tritium Plant associated to a reactor such as NET. The basic principles can be considered as acquired but in several fields, technology has to be improved. Fundamental studies have to be carried on to take optimized choices. 22 refs
