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.

Design of a small heating reactor based on boiling water reactor (BWR) technology necessitates major deviations from the standard fuel assembly design for a large BWR plant. The small core size results in an extremely high axial peaking factor detrimental to core performance. A spatial poison zoning technique was implemented to flatten power density and burnup profiles, which in turn allows almost complete burnable poison burnout at end of cycle. Separation of the cooling and moderating functions of the water was achieved by tightening the fuel assembly lattice with simultaneous increase of the interassembly gap. Thus, the hot-to-cold component of the total reactivity control requirement is decreased. Design of the control rod system with different compositions and geometries for various control rod banks was investigated in order to satisfy safety-related limitations on the reactivity worth of a single control rod.
