Abstract
He release from two ZrV_2 alloy tritide film samples was constantly measured for more than 1 500 d. Results show that release fractions of ~3He from two samples are still kept on the level of 10~(-4)~10~(-2) as that from ZrCo, Pa, Er and other metals or alloy tritides during the course of their early time release, without accelerating release phenomenon observed during 200~1 000 d from other alloy tritides. It certifies that ZrV_2 tritide is more capable for ~3He capture.
