ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.

Disney World should have gone nuclear
There is extra significance to the American Nuclear Society holding its annual meeting in Orlando, Florida, this past week. That’s because in 1967, the state of Florida passed a law allowing Disney World to build a nuclear power plant.

Behavior of edge plasma and neutral particles are described based on visible measurement by using high-speed camera performed in the GAMMA 10 tandem mirror for the first time. In the central-cell midplane of GAMMA 10, two high-speed cameras (Ultima-SE, Photron Inc. and MEMRECAM fx-K4, NAC Inc.) were mounted and detailed time behavior of visible light emission from the plasma was investigated. In the standard plasma discharges heated by ion cyclotron range of frequency (ICRF) wave, a short gas puffing of hydrogen (3 ms) close to the central-cell midplane was carried out to illuminate the plasma periphery and the time evolution of visible light emission from the gas cloud was captured precisely. The time behavior of the emission cloud localized near the gas puff port was found to be similar to that of H line intensity measured nearby. The light emission on the central-cell limiter accompanied by central electron cyclotron heating (c-ECH) showed a rotation in the direction of the electron diamagnetic drift. the light emission also indicates another rotation mechanism, such as ExB drift at a plasma collapse. Fully three-dimensional neutral transport simulation using a Monte-Carlo code DEGAS is applied to gas puff imaging experiment and the simulation results qualitatively explained the experimental result.
