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.

High-power negative and positive ion-based neutral beam injectors (NBIs) are operated with high reliability in the Large Helical Device (LHD). The total injection power is >20 MW, and such high-power beams are available every 3 min. The high performance of the LHD NBI system has extended the LHD parameter regime to levels equivalent to those obtained in large tokamaks. Three negative NBIs inject a total power of 16 MW with an energy of 180 keV, which is the world's highest power from a negative NBI system (H-), and one positive NBI (H+) injects 7 MW at 40 keV. The injection duration can be extended beyond 1 min with reduced power from the negative and positive NBIs, and long-pulse plasmas are successfully sustained with the NBIs. The structure and performance of the LHD NBI system is reviewed.
