Advanced Characterization System Deployments at the Hanford Site


G. M. Ceffalo, T. J. Snider


The Advanced Characterization System (ACS) uses off the shelf components in a pre-planned, staged system to provide overlapping data to locate and identity contamination in structures, systems and land area at Environmental Restoration Contract (ERC) work sites. Large areas, such as former plutonium production reactors and separations facilities are thoroughly and comprehensively characterized not only for decontamination and demolition, but also disposal and/or release. The ACS uses gamma-ray imaging instruments, in situ gamma spectrometry and large-area data-logging contamination survey meters to generate sufficient quality data to make operational and release decisions. The system is also used to safely characterize in-place systems without violating any containment, and localize activity in unusual situations.
