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.

A numerical method that is free from all spatial truncation errors is developed for one-group slab-geometry discrete ordinates problems. The unknowns in the method are the cell-edge and cell-average angular fluxes, and the numerical values obtained for these quantities are those of the analytic solution of the discrete ordinates equations. The method is based on the use of the standard balance equation, which holds in each spatial cell and for each discrete ordinates direction, and a nonstandard auxiliary equation that contains a Green’s function for the cell-average angular flux in terms of the incident angular fluxes on the cell edges and the interior source. Numerical results are given to illustrate the method’s accuracy.
