Hanford double-shell tank testing program - 15341

Abstract

The corrosion testing program and Hanford regularly tests waste chemistries to analyze threats and develop new corrosion chemistry guidelines. Over the past few years, the focus of testing has been on the threat of leaked wastes in Tank 241-AY-102 (AY-102). From the tests conducted to date, it appears that the potential waste compositions in the annulus of tank AY-102 do not show a propensity for localized corrosion or stress corrosion cracking. The threat of exterior corrosion from the liquid and moisture in the leak detection pit (LDP) is a potential concern that will continue to be evaluated in the coming year. (authors)
