Title: DESIGN CRITERIA FOR THE HIGH- AND INTERMEDIATE-LEVEL LIQUID WASTE FACILITY
Abstract: 1975 when a new, doubly-contained line was installed to service the expanded hydrofracture program. Since 1976, the ILW line has been under the control of the ORNL Surplus Facilities Management Program (SFMP). Due to the presence of contaminated soil at two former leak sites along the line, and the potential for radionuclide migration from that portion of the abandoned line that traverses White Oak Creek and the floodplain, decommissioning of the ILW line was given a high priority by the ORNL SFMP. In 1979, plans were initiated for corrective action along those portions of the line. The decommissioning activities have now been completed, with the abandoned line being placed in a condition that significantly reduces the hazards associated with it. The portion of the line in the White Oak Creek floodplain was removed, and the two leak sites entombed. This report presents the results of the ILW line decommissioning project, outlining the scope of the effort, describing the decommissioning experiences, and summarizing the project costs and schedules. 14 references, 30 figures, 3 tables.
