摘要
研究了未辐照ＵＯ＿２、（Ｕ，Ｐｕ）Ｏ＿２燃料在硝酸中的溶解行为。详细描述了硝酸浓度、温度、芯块加工方法和ＰｕＯ＿２含量等因素对溶解速度的影响，测定了溶解过程中钚价态变化和难溶残渣含量。
Dissolution behaviour of unirradiated LMFBR(U,Pu)O_2 fuel in HNO_3 is studied.Theeffects of HNO_3 concentration,dissolution temperature(U,Pu)O_2 pellet fabrication method(mechanical blending and AUPUC coprecipitating)and PuO_2 content on dissolution rate aredescribed in detail. The content of undissolved residues and the percentage of Pu(Ⅵ)in dis-solution solution are determined.
