Remote characterization of mixed waste by infrared spectroscopy: Fiscal year 1995 report

Abstract

Tank waste characterization requires various analytical systems to identify the chemical composition and water content of Hanford Site high-level waste to ensure that safety and environmental requirements are met and to provide stability and maintain the integrity of the tanks. An analytical database for the waste is also key to the design and implementation of pre-treatment and disposal processes. These tanks contain high-level mixed waste as sludge, saltcake, and supernate.

Quarterly report on the Ferrocyanide Safety Program for the period ending September 30, 1995

“…Because of delays in obtaining ratary-mode core samples from tank 241-BY-108, the report far that tank will be completed next quarter. 0 A final report summarizing Fourier transform infrared (FI'IR) work was issued this quarter (Rebagay et al 1995), completing FI'IR development work for the Ferrocyanide Safety Program.…”

“…The probe was interfaced to a new 80-fiber bifurcated fused silica bundle (40-fiber bundle for the infrared source and 40-fiber bundle for the detector assembly in a "salt and pepper" configuration) that can be detached from the fiber bundle for cleaning or replacement. (Rebagay et al 1995).…”
