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.

A semiempirical model, the so-called R-parameter model, introduced by Howerton and Plechaty has been proven to be a simple but, nevertheless, a very successful formalism for the description of gamma-ray spectra emitted in the course of nuclear reactions induced by fast neutrons. By the single parameter R, the gamma-ray spectrum will be predicted with a satisfying reliability in a wide range of nuclear masses and neutron incidence energies. The formalism is limited to neutron incidence energies below the (n,2n) threshold. Above this energy, a proposed modified ansatz yields good results.
