Division Spotlight
Reactor Physics
The division's objectives are to promote the advancement of knowledge and understanding of the fundamental physical phenomena characterizing nuclear reactors and other nuclear systems. The division encourages research and disseminates information through meetings and publications. Areas of technical interest include nuclear data, particle interactions and transport, reactor and nuclear systems analysis, methods, design, validation and operating experience and standards. The Wigner Award heads the awards program.

ARPA-E announces $40 million to develop transmutation technologies for UNF
The Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) announced $40 million in funding to develop cutting-edge technologies to enable the transmutation of used nuclear fuel into less-radioactive substances. According to ARPA-E, the new initiative addresses one of the agency’s core goals as outlined by Congress: to provide transformative solutions to improve the management, cleanup, and disposal of radioactive waste and spent nuclear fuel.

This paper investigates the interaction of energetic solar protons measured by the Geostationary Operational Environmental Satellites (GOES), with the aluminum shielding structure of different thicknesses and calculates the dose distribution inside an tissue equivalent phantom inside the aluminum structure. In addition to the incident energetic protons, the major contributors to the total dose inside the phantom are the secondary protons and neutrons generated by spallation reactions in the aluminum structure and the phantom. Three modes of incidence of source protons are considered: center seeking, planar, and isotropic. The center seeking mode is the most conservative, resulting in the highest dose values and distribution inside the phantom, compared to those at the phantom's outer surface. Both the planar and isotropic modes result in much lower dose values that are more evenly distributed throughout the phantom.
