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 and 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.
