1.1 This practice is a compilation of dissolution techniques for plutonium materials that are applicable to the test methods used for characterizing these materials. Dissolution treatments for the major plutonium materials assayed for plutonium or analyzed for other components are listed. Aliquants of the dissolved samples are dispensed on a weight basis when one of the analyses must be highly reliable, such as plutonium assay; otherwise they are dispensed on a volume basis.

1.2 The treatments, in order of presentation, are as follows:

Procedure TitleSection
Dissolution of Plutonium Metal with Hydrochloric Acid7.1
Dissolution of Plutonium Metal with Sulfuric Acid7.2
Dissolution of Plutonium Oxide and Uranium-Plutonium MixedOxide by the Sealed-Reflux Technique7.3
Dissolution of Plutonium Oxide and Uranium-Plutonium MixedOxides by Sodium Bisulfate Fusion7.4
Dissolution of Uranium-Plutonium Mixed Oxides and Low-FiredPlutonium Oxide in Beakers7.5

1.3 The values stated in SI units are to be regarded as standard.

1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
