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.

Neutron capture and transmission measurements have been carried out upon 182W, 183W, 184W, 186W, 90Zr, 91Zr, 92Zr, and 94Zr over the energy range from ∼150 eV to ≤100 keV at the Rensselaer Polytechnic Institute LINAC Laboratory. Many new resonances have been observed and many resonances, reported previously as singlets, have been resolved into doublets. Most of the resonances that previously eluded observation are assigned to p-wave neutrons. Pertinent resonance parameters have been extracted from the data, and the s-wave and the p-wave strength functions of tungsten and zirconium have been determined from these parameters. The values of the s-wave strength functions in units of 10−4 are: for 182W, 2.60 ± 0.54; for 183W, 2.41 ± 0.48 per spin state; for 184W, 3.0 ± 0.6; for 186W, 2.15 ± 0.46; for 90Zr, 2.0 ± 1.4; for 91Zr, 1.2 ± 0.4 per spin state; for 92Zr, 2.6 ± 1.5, and for 94Zr, 1.0 ± 0.8. The p-wave strength functions in units of 10−4 are: for the even-even tungsten isotopes, ; for 90Zr, 7 ± 4; for 91Zr, 3 ± 2 per spin state; for 92Zr, 7 ± 5, and for 94Zr, 4 ± 2.
