56.1 This test method covers the determination of 36 impurity elements in nuclear-grade plutonium dioxide (PuO2). The concentration ranges covered by the method and the analytical lines used for each element are listed in Table 1.
TABLE 1 Impurity Elements, Lines, and Concentration Limits
A These elements are determined with the aid of a microphotometer.
B These elements are analyzed by using a AgCl carrier and PdCl2 as an internal standard. Mix 20 mg of PdCl2 with 10.0 g of AgCl. Add 80 mg of this mixture to 120 mg of PuO2 sample-blend before loading 50-mg charges in a graphite electrode ASTM-Type-S-4 (follow 96.2.2).
106.1 This test method is applicable to the determination of the oxygen-to-metal atom ratio (O/M) in plutonium dioxide pellets and powders.
