Powering the future: How the DOE is fueling nuclear fuel cycle research and development
As global interest in nuclear energy surges, the United States must remain at the forefront of research and development to ensure national energy security, advance nuclear technologies, and promote international cooperation on safety and nonproliferation. A crucial step in achieving this is analyzing how funding and resources are allocated to better understand how to direct future research and development. The Department of Energy has spearheaded this effort by funding hundreds of research projects across the country through the Nuclear Energy University Program (NEUP). This initiative has empowered dozens of universities to collaborate toward a nuclear-friendly future.

SMART (simulation of many accumulative Rutherford trajectories) scattering theory is based on a scattering matrix designed to eliminate angular and possibly energy discretization errors. This is done without resorting to negative matrix elements. In effect, the true scattering law is replaced by one with fewer collisions but larger deflections per collision. The two scattering laws are equivalent, at least in space-independent calculations. To the extent that this equivalence holds true for space-dependent problems, the major numerical obstacle to electron transport modeling is removed. SMART scattering theory has been used in one-dimensional streaming ray and two-dimensional SN codes in lieu of Fokker-Planck or extended transport correction techniques, and in a one-dimensional discrete angle Monte Carlo code in place of the condensed history approach. Excellent results have been obtained.
