Technology, safety and costs of decommissioning reference non-fuel-cycle nuclear facilities: Compendium of current information
- Pacific Northwest Lab., Richland, WA (USA)
Cost and safety information is developed for the conceptual decommissioning of non-fuel-cycle nuclear facilities that represent a significant decommissioning task in terms of decontamination and/or disposal activities. Reference facilities examined in this study include six types of laboratories and three site elements associated with materials facilities that require some decommissioning effort. Decommissioning of these reference facilities and sites can be accomplished using techniques and equipment that are in common industrial use. Since decommissioning technology for non-fuel-cycle nuclear facilities has not changed appreciably since publication of NUREG/CR-1754, essentially the same technology assumed in that study is used in this study. For the reference laboratory-type facilities, the study approach is to first evaluate decommissioning of representative components (e.g., hoods, glove boxes, building surfaces, exhaust system ductwork, etc.) that are common to many laboratory facilities. Reference laboratories are then analyzed using data for individual components (the unit-component approach) to provide information about the costs and safety of decommissioning entire facilities. DECON is the decommissioning alternative evaluated for the reference laboratories because it results in release of the facility for unrestricted use as soon as possible. For a facility, DECON requires that contaminated components either be: (1) decontaminated to unrestricted release levels or (2) packaged and shipped to an authorized disposal site. 41 refs., 27 figs.
