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.

To test the recent advances in receptor modeling for the identification of long-range transport of regional source signatures of airborne particulate matter, an epithermal irradiation facility to determine indium has been specifically constructed. Analysis of filter samples collected weekly over a 5-yr period has indicated that indium in the arctic atmosphere is strongly dependent on season. Typical detection limits were 0.1 ng per one-eighth of a 20.3- × 25.4-cm Whatman filter. The airborne concentrations of indium are extremely elevated in the winter and spring months, and they almost disappear in the summer months. The application of the potential source contribution function has indicated that the indium originates from several areas in Eurasia as well as from known “hot spots” in North America.
