ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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.
