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.
Meeting Spotlight

WIPP’s SSCVS: A breath of fresh air
This spring, the Department of Energy’s Office of Environmental Management announced that it had achieved a major milestone by completing commissioning of the Safety Significant Confinement Ventilation System (SSCVS) facility—a new, state-of-the-art, large-scale ventilation system at the Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic (TRU) waste in New Mexico.

The scalar neutron spectrum per source neutron was measured with a miniature NE-213 spectrometer at several positions in water irradiated with deuterium-tritium neutrons. The measured spectrum was compared with a calculated one using the MORSE-GG Monte Carlo code with a modified point-detector estimator presented by Carter and Cashwell and the GICXFNS group cross-section set processed from the ENDF/B-IV library. The measured and calculated spectra agreed within the errors estimated from the statistical error and unfolding oscillations.
