Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

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.
