Transport equations in moving material Part I: Neutrons and photons

Our focuses are the fundamental equations and underlying dynamics of transport in moving backgrounds.The impacts in applications, important and legion, are detailed in the literature as cited. Accordingly, and invoking topic closure, applications are not recounted. Also, numerical techniques, developed with the emergence of supercomputing, are not treated herein. Both applications and numerical techniques are probably subjects of a separate communication Some modern transport codes dealing with moving material issues, however, are cited for reader reference. Many codes have been in existence for 25+ years, undergoing continuous updating, modification, improvement, and physical extension. For Part I, the main points of discussion and development are seen in the following Table of Contents, divided into neutron and photon moving material transport. An attempt at coverage of moving material transport with brevity is sought, and hopefully references provide details minimized, or not recounted, herein.
