NRC proposes changes to its rules on nuclear materials
In response to Executive Order 14300, “Ordering the Reform of the Nuclear Regulatory Commission,” the NRC is proposing sweeping changes to its rules governing the use of nuclear materials that are widely used in industry, medicine, and research. The changes would amend NRC regulations for the licensing of nuclear byproduct material, some source material, and some special nuclear material.
As published in the May 18 Federal Register, the NRC is seeking public comment on this proposed rule and draft interim guidance until July 2.

Kinetics for the reaction of oxygen with plutonium hydride have been measured in oxygen at 1.33 kPa and over a temperature range of 90 to 360°C. The initial reaction takes place with a very low activation energy and is limited by the formation of a protective oxide film. The protective nature of the oxide film product is dependent on the temperature. Once the oxide film is formed, the oxidation reaction is a linear process controlled by oxygen diffusion. Measurements were conducted on hydrides prepared from pure plutonium as well as a plutonium/gallium alloy.
