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.

Approximate solutions to the one-velocity neutron transport equation for an infinite cylinder with isotropic scattering and spatially piecewise constant cross sections are obtained by Fourier expansion of the neutron distribution function in one of the angular variables. An infinite coupled set of equations for the expansion coefficients is derived and general properties of the solutions to the truncated set of equations are discussed. A scheme for solving these equations by Gauss quadratures is given, and, as an example, the solution to the bare infinite cylinder critical problem is given in three orders of approximation. Excellent accuracy is obtained with a fairly small investment of analytical effort. The extension of the method to include the effects of anisotropic scattering is sketched.
