Significance and Use:

The test method is designed to show whether or not a material meets the specifications as given in Specifications C 753 or C 776.

The powder’stoichiometry is useful for predicting the oxide’sintering behavior in the pellet production process.

Scope:

1.1 This test method covers the determination of uranium and the oxygen to uranium atomic ratio in nuclear grade uranium dioxide powder and pellets.

1.2 This test method does not include provisions for preventing criticality accidents or requirements for health and safety. Observance of this test method does not relieve the user of the obligation to be aware of and conform to all international, national, or federal, state and local regulations pertaining to possessing, shipping, processing, or using source or special nuclear material.

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.

1.3 This test method also is applicable to UO 3 and U3O8 powder.
