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 energy spectrum and angular distributions of protons emitted from the 93Nb(n,p) reaction have been measured at a bombarding energy of 14.1 MeV with a position-sensitive counter-telescope. The energy spectrum is well explained by the sum of the spectra calculated on the basis of the preequilibrium and statistical evaporation models. The angular distributions are successfully reproduced by means of the generalized exciton model. The multistep direct reaction model indicates a little discrepancy in the absolute cross section in spite of general agreement in the shape of the angular distributions.
