Generic cost estimates for the disposal of radioactive wastes

NRC regulatory impact analyses address the costs and benefits associated with proposed regulatory requirements. Many of these requirements will result in physical modifications to existing structures and systems at nuclear power plants. This report provides a methodology and data needed to estimate the generic costs of disposing of radioactive wastes that may be generated as a result of NRC regulations requiring modifications or repairs to nuclear facilities. Also presented are descriptions of typical low-level radioactive wastes generated at nuclear power plants and the various processes used to treat the wastes in preparation for shipment and burial. The waste disposal cost estimates included in this report cover all the major elements that contribute to the overall costs. The key factors that influence the costs are discussed. Pertinent ranges of values for the key variables are explored and important sensitivities identified. The cost implications of the burial surcharges authorized by the Low-Level Radioactive Waste Policy Amendments Act of 1985 are covered. Occupational radiation exposure associated with in-plant handling of the wastes is also discussed. This report updates and revises information presented in NUREG/CR-4555. 39 figs., 33 tabs.
