The tritium control is a very important issue for a D-T fueled fusion reactor, because not only tritium is very expensive but tritium leakage causes environmental contamination. Usually the allowable tritium leakage rate of a fusion reactor should be less than 3.70×10~(11)Bq·d~(-1) to the environment. For FEB-E design, the high-pressure helium gas is used as the coolant, liquid lithium as the tritium breeder, hence the produced tritium in liquid lithium has strong chemical affinity with lithium into LiT. Under the normal operational circumstances, the FEB-E blanket temperature≤680℃, the tritium permeation leakge throuth blanker structural materials is
