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.

Inelastic scattering of 25.7-MeV neutrons to unresolved final states with excitation energies up to ∼13 MeV were measured for monoisotopic samples of 51V, 56Fe, 65Cu, 93Nb, and 209Bi. Neutrons were produced via T(d,n)4 He reaction in a gas cell that provides a background-free source spectrum above En = 12 MeV. Time-of-flight spectra were taken at several angles between 25 and 145 deg using the beam-swinger spectrometer. The technique of dynamic biasing proved valuable in providing maximum detector efficiency and low background throughout the broad range of neutron energies. Data were converted to energy spectra, corrected for detector efficiency, averaged over 1-MeV bins, and corrected for sample attenuation and multiple scattering.
