【摘要】 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(Tritiumheel),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。更多还原

【Abstract】 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.更多还原
