标准摘要
[中文适用范围]： 该方法规定了通过化学溶解后的重量分析来测定混合氧化物（MOX）燃料颗粒中的氧/钼比（O/M）。 [外文原描述]： ISO 21484:2017 describes a method for determining the Oxygen-to-Metal (O/M) ratio in mixed uranium-plutonium oxide (U,Pu)O 2 ± X pellets. The parameters given in the following paragraphs are relevant for pellets within a range of O/M ratio corresponding to 1,98 to 2,01. The method described in the document is adapted, with regard to the parameters, if the expected values of O/M ratio are outside the range.
