摘要

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