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.

A new method of synthesis of the time-dependent behavior of a neutron pulse or of the space-dependent transfer function is given which combines analytical time dependence with numerical (or analytical) dependence of the other variables. The analytical development in Laguerre polynomials of time is obtained recursively in solving iteratively the static Boltzmann equations with sources. The convergence of the development, the bound of the truncation error, and the choice of the free parameters are examined for various cases. The method is finally applied (using an experimental map of the steady flux) in a water slab and the synthesized time-dependent flux is compared to the experimental one.
