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.

Fast neutron irradiation to total fluences ranging from 7.7 × 1021 to 5.7 × 1022 n/cm2 (3 to 16 dpa) resulted in a 65% increase in yield strength and a fourfold reduction in ductility. Intergranular fracture was the dominant failure mode for the irradiated material, whereas equal amounts of intergranular and trans-granular cracking were found in the unirradiated condition. This fracture mechanism transition resulted from intense heterogeneous deformation in a matrix strengthened by an irradiation-produced dislocation substructure. Planar slip bands impinged on the grain boundaries causing very high local stresses. Intergranular cracking resulted because the hardened matrix prevented relaxation of the stress concentrations.
