摘要: 通过核素高温损失试验、混合溶解试验及干扰影响研究,形成了一种适宜的放射性有机沉积物预处理方法。高温碳化+混合酸处理过程反应温和,无液体飞溅情况,降低了气溶胶产生几率,关注核素(90Sr、137Cs、241Am、239Pu)的回收率均大于91%。实际样品经本方法处理可完全转化为水溶液,关注核素测量结果相对标准偏差均小于9%,为后续高水平放射性有机沉积物处理处置提供准确的数据基础。

Abstract: Through high-temperature nuclide loss tests, mixed dissolution tests and interference influence studies, a suitable pretreatment method for radioactive organic deposits was formed. The high-temperature carbonization + mixed acid treatment process has a mild reaction without liquid splashing, reducing the probability of aerosol generation. The recovery rates of the nuclides (90Sr, 137Cs, 241Am, 239Pu) are all greater than 91%. The actual samples can be completely converted into aqueous solutions after being treated by this method. The relative standard deviations of the measurement results of the nuclides are all less than 9%, providing an accurate data basis for the subsequent treatment and disposal of high-level radioactive organic deposits.

Key words: organic deposits, degradation of material, pretreatment
