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 prescription for the third basis function relevant to an approximate model of neutral particle transport in ducts is given. When a third basis function is included in the model, the full five-variable differential equation that describes time-independent particle transport in a duct is reduced to a three-group-like transport equation in two variables (one spatial, one angular). Numerical results based on the discrete ordinates method for a series of test cases are compared with results from a suitably modified version of the MCNP code to assess the gain in precision of the model with three basis functions relative to previous versions of the model that make use of only one or two basis functions.
