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 total attenuation coefficients are measured for seven alloys at 84 and 145 keV by the transmission method using a good geometry setup employing a NaI(Tl) scintillation spectrometer. The scattering contributions are deduced using the theoretical cross sections taken from the recent literature and are subtracted from the measured total cross sections to get the photoelectric cross sections. Finally, the effective atomic numbers are obtained from the graph of cross section versus the atomic number. Results are compared with semiempirical estimates and are found to be in good agreement. Results are also compared with the available experimental values, some of which are reported at 412 keV and some at 52.5 keV and a good agreement is noted.
