The optimized assured isolation facility (AIF) consists of waste shipping containers being placed inside steel-reinforced concrete overpacks, which are, in turn, placed in steel-reinforced concrete vaults without an earthen cover system. The concrete vaults are designed to remain in service for hundreds of years, with the aid of ongoing active maintenance. This will be required since the facility will remain under license as long as waste is present in the facility. The estimated present value of life-cycle costs total about $318 million. Of this amount, over 30 percent is attributable to the need to accumulate the financial assurance fund which allows future management options to be implemented. The charge for waste received at the AIF in order to recover all costs and ensure proper facility function following the waste acceptance period was calculated for each year of AIF operation, considering annual variations in the volume received and the costs that must be recovered. The present value of the AID unit charges range for $84 to $420 per cubic foot with a life-cycle average of about $177 per cubic foot. When making decisions on cost factors and comparing alternatives, the lifetime average of $177 per cubic foot is most meaningful.
