Lesson Learned Statement:Sampling activities, such as determining the number of waste streams present, the number of samples required and the containers required for the waste materials for waste characterization should be performed prior to the start of a Project. Because these activities weren’t completed until after the commencement of the dismantlement activities, the Acid Recover Pump Room (ARPR) project was delayed, both in the packaging of the waste materials which were being generated and the sampling which was required to perform characterization.
Discussion:The project entailed the decontamination of the ARPR in its entirety. Decontamination efforts encompassed the removal of all loose debris from the ARPR and vacuuming the ARPR floor. Permanent utilities to the ARPR had to be isolated. The process lines within the ARPR were drained of liquids as necessary and subsequently isolated to ensure against inadvertent intrusion of additional liquids. The tank, pumps, electrical and instrumentation components, process and utility piping, HEPA filters, and miscellaneous debris were size reduced as necessary and removed from the ARPR. The final state of the ARPR is that the walls, ceiling, and floor are free of any components or equipment.
