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.

WIPP’s SSCVS: A breath of fresh air
This spring, the Department of Energy’s Office of Environmental Management announced that it had achieved a major milestone by completing commissioning of the Safety Significant Confinement Ventilation System (SSCVS) facility—a new, state-of-the-art, large-scale ventilation system at the Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic (TRU) waste in New Mexico.

The statistical method for calculating neutron cross sections in the unresolved resonance region has been extended to permit the construction of ladders for higher angular momentum neutrons and for all accessible spin states (and substates) of the compound nucleus. The new method is an improvement over existing methods in that a fitting procedure is adopted to ensure that the constructed sequence of resonances reproduces resonance integrals inferred from low-resolution experimental results. The s- and p-wave components of the capture cross section of 238U have been computed between 4 and 80 keV using a sequence of resonances obtained by fitting over the energy range 4 to 15 keV. The calculated 238U capture cross section is in excellent agreement with published data in the energy range 25 to 60 keV.
