摘要
This paper introduces the first results of deuterium retention on the Experimental Advanced Superconducting Tokamak（EAST） using particle balance. In the fall 2010 EAST experiments with a full graphite wall, the average deuterium retention fraction was about 19%（including disruptive shots） and 38%（not including disruptive shots）. Fuel retention for the short-and longpulse discharge was different. The H-mode discharges had a slightly lower fuel retention than the L-mode discharges. However, it was observed that disruptions introduced outgassing from the wall. Wall conditioning, such as lithium coating, increases retention.
