摘要
Abstract
The condition of adjusting Np,Pu,U valence to Np(Ⅳ),Pu(Ⅳ)and U(Ⅵ)by H 2 O2 has been studied,and 1.5% H2 O2 is used to adjust the valency of Np,Pu,U in 6 mol/L HNO3 ,after loading and washing.The yields of Pu,Np,U are 99.8%,1 1 9%,91.5%when they are stripped independently,the decontamination factor of 1 3 7 Cs is 7.4×10 4 .The operation time will be 1-1.5 h for one sample.If ED-XRF is involved to analyze Np and U, this two elements could be stripped together.The yields of U,Np are 102.4%,93.9%. The results meet the request of analysis and radiation protection for 1AW sample.关键词
