Decontamination and decommissioning of the fission product pilot plant at the Oak Ridge National Laboratory

PDF Version Also Available for Download.

Description

The Fission Product Pilot Plant (FPPP) at the Oak Ridge National Laboratory (ORNL) was one of the first facilities used to extract radioactive isotopes from liquid radioactive wastes. During operations, the FPPP was extensively contaminated, resulting in high radiation levels even 30 years after the conclusion of operations. The facility has been abandoned for over 20 years and is now a candidate for decontamination and decommissioning (D&D). In fact, the ORNL management has begun activities toward the D&D of the FPPP. Two of these activities were completed in 1993 and 1994. The first 2030 activity was a facility characterization designed ... continued below

Description

The Fission Product Pilot Plant (FPPP) at the Oak Ridge National Laboratory (ORNL) was one of the first facilities used to extract radioactive isotopes from liquid radioactive wastes. During operations, the FPPP was extensively contaminated, resulting in high radiation levels even 30 years after the conclusion of operations. The facility has been abandoned for over 20 years and is now a candidate for decontamination and decommissioning (D&D). In fact, the ORNL management has begun activities toward the D&D of the FPPP. Two of these activities were completed in 1993 and 1994. The first 2030 activity was a facility characterization designed to assess the condition of the interior of the FPPP and to quantify, if possible, the amounts and identities of any radioactive contaminants and hazardous materials as defined by the U.S. Environmental Protection Agency. The facility characterization was intended to determine the condition of the interior, the complement of equipment left in the facility at the time of its closure, and the radiation environment that would be encountered during its D&D. The second activity was an alternatives assessment designed to determine the best approach to the D&D of the FPPP. The alternatives assessment examined five alternatives to decontaminate and decommission the FPPP and recommended the best alternative for its disposition. The first section of the paper describes the FPPP and its history. It includes the various conjectures on what exactly was done when the FPPP was entombed with the shield wall visible in today`s pictures. The next section discusses the characterization that was performed concurrently with the alternatives evaluation. The next two sections detail the D&D plan for the complete dismantelment of the FPPP and its estimated cost and schedule.
