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 new nodal approach for global reactor core calculations is described, in which local weighted residual procedure equations are consistently embedded into a classical nodal scheme without the necessity of a transverse leakage fitting approximation. The equations derived are formulated for arbitrary node geometry and a wide class of base functions. Simplicity and efficiency of the final relations are assured for regularly shaped nodes by means of symmetry considerations. Application to hexagonal geometry of nodes is discussed. Numerical results for few-group steady-state problems in hexagonal geometry prove highly accurate, comparable to analytic codes, and better with respect to computational efficiency.
