摘要
对两块锆钒氚化膜中3He释放进行4 a跟踪监测。测量结果表明:其释放系数(RF)一直保持在10-4~10-2量级,与文献所报道的锆钴合金、钯、铒等金属的氚化物早期的3He释放基本上处于同一水平。其区别在于,随着时间的增长,其它金属的氚化物在200~1 000 d内达到3He的加速释放,而锆钒合金贮存已1 500 d,仍无3He的加速释放迹象。这种现象说明锆钒合金具有更强的固氦能力。
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.
