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 simple flow pattern map (vm versus α coordinates) is proposed that provides computational means for selecting steam/water two-phase flow constitutive equations. This flow pattern map can easily be implemented in a thermal-hydraulic code. Determination of the map boundaries between different flow patterns for any channel hydraulic diameter is feasible. This determination is based partially on theoretical criteria that were developed for adiabatic two-phase flows and partially on physical reasoning. Good agreement is obtained between the predicted map regions and experimental data from uniformly heated four-rod bundle and tubes setups.
