摘要

The world’s first permanent radioactive waste repository, the Waste Isolation Pilot Plant (WIPP) in New Mexico, began receiving transuranic waste shipments in 1999. WIPP is scheduled to receive up to 1,000,000 waste containers from Department of Energy facilities over the next 20 years. Each container (typically 55-gallon drums) must be thoroughly characterized for both radioactive and non-radioactive content to verify compliance with waste acceptance requirements. For example, the drum headspace must be analyzed for 30 organic analytes to determine flammability. Traditionally, this analysis has been performed using SUMMA canister sampling followed by laboratory GC/MS analysis. Considerable cost savings can be achieved, while meeting QA and detection requirements, by conducting on-site headspace analysis by Fourier Transform Infrared Spectroscopy (FTIR). Consequently, the Idaho National Environmental and Engineering Laboratory developed an FTIR method that has been approved for transuranic waste characterization. FTIR-based headspace analysis systems have been deployed as fixed installations (INEEL) and mobile systems (Nevada Test Site, Lawrence Livermore Laboratory) for waste characterization. In a single measurement lasting less than 5 minutes the FTIR system performs an automated analysis for the 30 organic compounds in addition to several other species. Results from field evaluations and comparisons with GC/MS analyses are discussed.
