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 residual method of orthogonal collocations (OCs) is evaluated on the basis of three problems of increasing degree of complexity. Two model problems, a Poisson equation and a wave front propagation problem, allow a comparison with known analytical solutions and other numerical results obtained with finite differences or with the classical Galerkin method. The third problem consists of the numerical solution of the equations describing a one-dimensional sodium vapor flow, obtained using a variant of the BL0W-3A computer program developed for this purpose. Shape functions of second degree are used throughout the analysis. The results show the applicability of the OC technique to two-phase flow problems.
