Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

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.

Three techniques for particle diagnostics of magnetically confined fusion plasmas are reviewed: charge exchange neutral particle analysis, Rutherford scattering, and heavy ion beam probes. The physical basis and instrumentation for each technique are described. Typical examples obtained by these diagnostics are presented. Charge exchange analysis is used for ion temperature measurements in small- and medium-sized plasma devices and for the study of the ion energy distribution function, especially in the suprathermal energy range. It also provides an ion isotope composition determination that is a high-priority task for ITER. Rutherford scattering enables local measurements of the ion temperature as well as measurements of the ion collective velocity. The heavy ion beam probe diagnostic gives a unique opportunity to measure locally the electric plasma potential and, by that, the electric field profile in a plasma and its influence on confinement. Other significant options of this diagnostic are the measurements of the local electron density and fluctuations in these quantities. Prospects for the application of the various techniques to ITER are discussed.
