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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

Steam generator tube rupture sequences are identified as major contributors to the risk assessments of pressurized water reactors. Despite very low probability, they involve a direct pathway for radioactivity release into the environment. Nonetheless, fission products could be partially retained in the secondary side of the steam generator, even in the absence of water. This paper summarizes the main results of a bench-scale experimental program focused on the aerosol retention near the tube breach at the secondary side of a dry steam generator. The major variables investigated were the breach configuration (i.e., type, orientation, and location) and the gas mass flow rate. The results showed that near the breach, aerosol retention is low (<20%), and it generally decreases when the gas mass flow rate increases. Discussion of the experimental results suggested that certain phenomena, such as fragmentation and/or resuspension, as well as particle nature could have a large effect on the scenario studied, and they should be considered as potential issues and/or variables to be explored in future work.
