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 probability table representation of neutron transport in bubbly media, developed by Hoffman and Petrie for neutron flights initiated by collision, is extended to neutron flights initiated at interfaces. Both forms are compared with appropriate Monte Carlo estimates of one-flight transmission through bubbly slabs, with encouraging results for slabs thicker than the bubble diameter. These forms are then combined into a modified probability table method. Application of the modified method to transport calculations requires high spatial and angular resolution but shows that the interface modification can have a substantial effect on calculated bubble worths. Fortunately, the results agree well with the simple Benoist method, which does not require high resolution.
