Decontamination and decommissioning of the TAN/TSF-3 concrete pad. Final report

Technical Report ·
OSTI ID:6928883

This report describes the decontamination and decommissioning (D and D) of the TAN/TSF-3 concrete pad at the Idaho National Engineering Laboratory (INEL). This pad became contaminated in the 1960s and had been roped off until the 1983 decommissioning. The report includes radiological characterization of the pad area before D and D, after D and D, and after backfilling and grading. To accomplish the selected alternative of completely removing the concrete and contaminated soil, the pad was sawed into sections; the concrete and surrounding soil were boxed and shipped to the Radioactive Waste Management Complex for burial. The excavated area was then backfilled and graded. Soil samples collected and analyzed as well as radiation fields measured after D and D yielded results that permit the area to be released for further use at INEL for equipment storage, or some other appropriate use. 5 references, 20 figures, 6 tables.
