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.

NWTRB to hold public meeting on SNF disposal and corrosion
The Nuclear Waste Technical Review Board, an independent federal agency that evaluates the Department of Energy’s efforts to manage and dispose of spent nuclear fuel and high-level radioactive waste, will hold a two-day public meeting May 21–22 to review information on the DOE’s research and development activities related to the disposal of SNF and HLW in crystalline host rocks and on the corrosion of commercial SNF after disposal.

Work involving the selection and burn stability control of near-ignited operating points f or the International Thermonuclear Experimental Reactor (ITER) is described. Using simple volume-averaged zero-dimensional transport models, it is suggested that ITER operation at high densities (1 to 2 × 1020/m3) and low temperatures (6 to 10 keV) may be necessary, or even desirable, even though these plasma parameters are intrinsically thermally unstable. It is argued that these thermal instabilities can be effectively controlled using active feedback based on standard diagnostic signals. In particular, the physical and technological feasibility of three control methods, modulation of neutral beam power, modulation of fueling rate, and controlled injection of impurities, is considered, and recommendations regarding the applicability of these methods to ITER are made.
