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.

Several methods for sampling the Klein-Nishina distributions for scattered photon secondary energy are studied to determine an optimum sampling technique useful from 1 keV to 100 MeV. A commonly used approximate inverse method is evaluated for accuracy by analytically comparing the exact and approximate sampling distributions. This method, several rejection methods, and an exact direct sampling method are evaluated for computing speed on several different computers.
