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.

Green’s function nodal expansion method (GNEM) is developed for the efficient numerical solution of the multidimensional neutron diffusion equation. It is an improved version of the nodal expansion method (NEM) and the nodal Green’s function method (NGFM). The node interior fluxes are approximated by a high-order polynomial expansion as in NEM. The nodal surface fluxes are coupled with the net currents by using the Green’s function method to improve accuracy. The GNEM computer code is encoded and tested. The numerical results demonstrate that GNEM has the same accuracy as NGFM while it is twice as fast as NGFM.
