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.

Total attenuation cross sections in six alloys at 662-keV photon energies are measured by a transmission method using a NaI(Tl) scintillation spectrometer. The cross sections for the photoelectric process and for coherent scattering are deduced using theoretical cross sections taken from recent publications and are subtracted from the measured total attenuation cross sections to get the incoherent scattering cross sections. Finally, effective atomic numbers for the total gamma-ray interaction and for the incoherent scattering process are obtained by interpolation from graphs of the respective cross sections versus atomic numbers. The results are compared with effective atomic numbers estimated using semiempirical expressions.
