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.

The results of a numerical analysis of the eigenvalue spectrum and eigenmodes of the monoenergetic integral transport equation are presented. Anisotropic scattering effects are explicitly considered with P1 and P2 expansions. Benchmark quality data are produced for three related onedimensional homogeneous multiplying slab problems: fuel with vacuum boundary, fuel with reflectors, and fuel/reflector infinite lattice. Two low-order spatial expansion techniques are investigated and shown to be equivalent in accuracy to analytical or high-order spatial expansion methods. The weak finite element formulation is shown to be slightly more accurate than the comparably sized quadrature formulation. The calculational results of the isotropic and anisotropic analysis are compared with data available in the literature and extended to provide additional results reflecting the effects of linearly and quadratically anisotropic scattering.
