Standard Specification for Nuclear-Grade Plutonium Dioxide Powder, Sinterable

1.1 This specification covers nuclear grade plutonium dioxide, sinterable powder obtained by the oxalate precipitation route, calcined above 500°C, or any other equivalent process acceptable to the purchaser. Included is plutonium dioxide of various isotopic compositions as normally prepared by in-reactor neutron irradiation of natural- or slightly enriched uranium or by in-reactor neutron irradiation of recycled plutonium mixed with uranium.

1.2 There is no discussion of or provision for preventing criticality incidents, nor are health and safety requirements, the avoidance of hazards, or shipping precautions and controls discussed. Observance of this specification does not relieve the user of the obligation to be aware of and conform to all Federal, state, and local regulations on processing, shipping, or using source or special nuclear materials. Examples of U.S. Government documents are N7.2 Radiation Protection in Nuclear Reactor Fuel Fabrication Plants, Code of Federal Regulations, Title 10 Nuclear Safety Guide, U.S. Atomic Energy Commission Report TID-7016, and "Handbook of Nuclear Safety", H. K. Clark, U.S. Atomic Energy Commission Report, DP-532.

1.3 The PuO₂ shall be produced by the processor employing a qualified process and in accordance with a quality assurance program approved by the user.

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

1.5 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.
