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 study of the spectral radius for the continuous form of the source iteration, diffusion synthetic acceleration, and various PL acceleration methods (L ≥ 1) for anisotropically scattering neutron transport is carried out via a Fourier stability analysis. The purpose of the study is to determine which acceleration scheme is optimum. The problem is formulated as a matrix eigenvalue problem with, in general, N + 1 iteration eigenvalues ω where N denotes the degree of anisotropy. The P1 acceleration method is determined as the most efficient PL approach for the cases of linearly and quadratically anisotropic scattering.
