ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

Using the Oak Ridge Electron Linear Accelerator pulsed neutron source and a 1-mm-thick lithium glass detector, neutron transmission spectra through 232Th have been measured at 22- and 40-m flight paths. At 22 m, transmission spectra through samples of five thicknesses were measured from 7 meV to 15 eV. At 40 m, spectra through samples of eight thicknesses were measured from 15 eV to 4 keV. The resulting total cross section from 0.1 to 20.0 eV is smaller than that given by the ENDF/B-V evaluation. Least-squares shape analysis of the transmissions up to 2.0 keV gives larger neutron widths above 0.5 keV than those previously reported. An average radiation width of 25.2 meV is obtained for 19 low-energy s-wave resonances.
