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.

The Magnetized Liner Inertial Fusion experimental campaign conducted at the University of Rochester’s Laboratory for Laser Energetics has evolved significantly since its start in 2014. Scientific requirements and OMEGA Extended Performance (EP) system technology both have progressed, resulting in necessary and available updates to the target design. These include, but are not limited to, optimizing target dimensions and aspect ratios to maximize survival at desired pressures; coating target components to improve physics diagnosis; precision-machining diagnostic windows along the axis of the target for enhanced diagnostic views; improving fiducial placement reproducibility and reducing subsequent assembly time by 50%; and implementing gas-pressure transducers on the targets. In addition, target fabrication techniques have changed and advanced, allowing for better target reproducibility and decreased assembly time. To date, 11 variations of targets have been fabricated, with successful target fielding ranging from 1- to 20 atm internal pressure and a maximum survivability of 33 atm.
