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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

A scanning electron microscope is used to investigate techniques for performing microanalysis of highly radioactive material from the Three Mile Island Unit 2 reactor. Wavelength dispersive X-ray (WDX) spectrometer methods allow quantitative analysis of metallic and oxide phases in samples with radiation fields of up to 60 R/h (contact β-γ). It is found that sputtered gold provides an unexpectedly useful specimen coating for remote analysis, being easily applied and forming more uniform layers than evaporated carbon, and proving compatible with quantitative point analysis. Through a combination of electron imaging, shielded energy dispersive spectrometry, WDX dot mapping, and quantitative WDX point analysis, it is possible to obtain data on core metal oxidation, trace concentration fission product distribution, and phase composition for core temperature estimation.
