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.

Neutron total cross sections in the energy range from 1 to 11 MeV have been experimentally evaluated for several shielding materials by comparing calculations and measurements of the spectra of the uncollided flux transmitted through thick samples. This technique provides a critical test of the minima in the cross sections but yields little information about the resonance regions. Special emphasis has been placed on evaluating the total cross sections in the Evaluated Nuclear Data File (ENDF/B), which, in most cases, are the best available, the exceptions being for iron and tungsten.
