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 simple calculational method is developed that can quickly and accurately estimate total control rod worth for a class of reactors possessing fuel/control channel symmetry throughout its core. The movable, nonfissionable, poisoned control channel has identical neutron absorption and scattering properties and geometry similar to the fuel channels. Hexagonal lattices employed in fast breeder and graphite-moderated thermal reactors possess the necessary fuel/control lattice symmetry with spectrally innocuous coolants for both channels (sodium or helium both for fast and thermal systems) required to apply the method. The number of fuel and control channels is the parameter determining control worth and is tantamount to estimating by inspection. It is applied to eight fast sodium-cooled reactors and four thermal-, sodium-, or helium-cooled, graphite-moderated reactors. The Δk/k estimated worths are generally better than ±20% plant values.
