Title: Solid Phase Characterization of Tank 241-AY-102 Annulus Space Particulate

Abstract

The Special Analytical Studies Group at the 222-S Laboratory (222-S) examined the particulate recovered from a series of samples from the annular space of tank 241-AY-102 (AY-102) using solid phase characterization (SPC) methods. These include scanning electron microscopy (SEM) using the ASPEX®1 scanning electron microscope, X-ray diffraction (XRD) using the Rigaku®2 MiniFlex X-ray diffractometer, and polarized light microscopy (PLM) using the Nikon®3 Eclipse Pol optical microscope. The SEM is equipped with an energy dispersive X-ray spectrometer (EDS) to provide chemical information.

  • Corrosion product from the annulus side of the double-shell tank 241-AY-102 primary wall was retrieved and analyzed. The analyses indicated that the tank wall was wetted with water leading to corrosion. The water source was quite likely the ingress of water from an external source and condensation of moisture during the long annulus ventilation system shutdowns. Corrosion of the primary tank wall in the annulus of double-shell tank (DST) 241-AY-102 was observed during the review of annulus videos of the tank in year 2001. This resulted in the issuance of an occurrence report, RP-CHG-TANKFARM-2001-0106. The occurrence report required collection andmore » evaluation of the corrosion product to determine the cause of such corrosion. Therefore, a corrosion product sample was collected from the annulus side of the primary wall through Riser 80 in February 2003. The sample was scanned by Operational Health Physics and found to contain no radioactivity. The sample was then released and transmitted to ChemMet, Ltd , PC, for analyses. The present report discusses the types of analyses performed and the results of these analyses from ChemMet, Ltd , PC (Divine 2003) along with conclusions and recommendations. The letter report from ChemMet, Ltd, PC is attached.« less

  • As part of the program to provide waste characterization and pretreatment data to support the Waste Treatment Plant WTP mission to treat Hanford tank waste, an approximate 3.8L sample of waste from Hanford Tank 241-AY-102/C-106 was received at the Savannah River Technology Center (SRTC). The waste sample was characterized to provide feed for pretreatment testing. The characterization data provides a basis for rational development of pretreatment processes, determination of reagent requirements, and development of physical design parameters for the pretreatment plant.

  • This report documents the chemical compatibility of waste types within tanks 241-C-106, 241-AY-101, and 241-AY-102. This information was compiled to facilitate the transfer of tank 241-C-106 waste to tank 241-AY-102 utilizing supernatant from tank 241-AY-101 as the sluicing medium. This document justifies that no chemical compatibility safety issues currently understood, or theorized from thermodynamic modeling, will result from the intended sluice transfer operation.

  • This test plan describes a sample separation method which will be used to obtain physical measurements and separated 241-C-106 solids and supernate fractions. In addition compatibility of tank 241-C-106 sludge with tank 241-AY-102 supernate will be determined.
