老化氚化铀的解吸等温线测定

为丰富氚化铀老化后的解吸等温线数据，测定了氚化铀样品静态贮存0，460，610，1720d的解吸等温线。实验结果表明，氚化铀贮存一段时间后，样品解吸等温线的坪区依然平坦，坪压没有显著改变，氚解吸后不会留有显著的氚渣(Tritium heel)，且氚在铀中的可逆吸附容量不因老化而显著减少，表明铀的氚老化效应比较轻微，适合长期贮氚。

Determination of the Equilibrium Desorption Isotherms for Aged Uranium Tritides

The desorption isotherms of uranium tritide samples that have been stored at ambient temperature for 0,460,610,or 1 720 d respectively under different desorption temperatures are measured. The experimental results show that the range,slope,and pressure of the plateau on the isotherm of each aged UT_x samples are kept essentially unchanged in comparison with that of unaged UT_x sample. Tritium heels left in the samples after desorption are negligible. No remarkable decrease in the rever-(sible) storage capacity for tritium is observed. It is concluded that the effect of tritium aging on tritium storage is very small, and uranium tritide seems suitable as a good medium for long-term storage of tritium.
