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.

Waste retrieval underway on third set of underground tanks at Hanford
Work crews have started retrieval of radioactive and chemical waste from a third set of underground storage tanks at the Hanford Site, according to the Department of Energy's Office of Environmental Management. Contractor Washington River Protection Solutions (WRPS) is retrieving and transferring more than 325,000 gallons of waste from the single-shell Tank A-101 at the site's A Tank Farm. The waste is being sent to a newer double-shell tank for continued safe storage.
Retrieval activities began one month after workers emptied the site’s 21st single-shell tank. Waste removed from the 21 tanks totals about 3 million gallons.

Current profile reproduction has been considered one of the key issues for control and evaluation of a tokamak plasma. Although magnetic measurements exterior to a plasma provide the most reliable data necessary for profile reproduction, the reproducibility from the magnetic measurements is unclear, and the regularization against numerical ill posedness improperly restricts reproducible profiles. To solve the inverse problem, at first, a new method is proposed for the current profile reproduction using a function expansion. Second, with the eigenfunctions in this method, a reproducibility check is analytically formulated. Finally, a new constraint for the plasma interior is derived from the MHD equilibrium equation. In the next step, this constraint must be included to enable reliable reproduction of current profile.
