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.

A practical formula for sensitivity coefficients of burnup properties has been derived by means of a generalized perturbation theory. A differential method is employed. The resultant formula corresponds to an extension of the Williams formula, which is based on a variational method. The applicability of the proposed formula is investigated by calculating sensitivity coefficients in a typical fast breeder reactor and by comparing the results with those from the direct subtraction calculations. The physical meanings of components of the coefficients are discussed.
