Testing a predictive model for repository cost-- the Waste Isolation Pilot Plant experience

The Department of Energy (DOE) has developed a series of cost estimating models (called FAST), originally under the Assistant Secretary for Nuclear Energy and currently under the direction of Assistant Secretary for Defense Programs. One model, an equipment estimating methodology, was used extensively to test the Waste Isolation Pilot Plant (WIPP) equipment estimate validity. A mining and total repository estimating model has also been developed. Along with the other information sources, WIPP design and historical experience were used extensively in the development of this model. The primary focus of this paper will be on the progress of the WIPP Project and the state-of-the-art cost modeling of geologic waste storage facilities
