摘要: Abstract JET's 1997 Deuterium Tritium Experiment (DTE1) allows a detailed study of hydrogenic isotope recycling and retention in pumped divertor configuration relevant to ITER. There appear be two distinct forms retained tritium. (1) A dynamic inventory which controls the fueling behaviour single discharge, particular determines isotopic composition. This is shown consistent with neutral particle implantation over whole vessel surface area. (2) continually growing inventory, plays small role balance but ultimately dominates for an experimental campaign comprising thousands pulses. will dominant mechanism long-pulse devices like The JET scaled-up ITER proportions suggests that may reach its tritium limit less than 100
