The radioactive waste stored in Hanford's underground tanks was primarily generated in chemical processes where it was made alkaline before being sent to the waste tanks. A summary evaluation was made of a recent issue concerning the storage of radioactive waste with a pH of about 7 in some of these tanks. This document supplements the information presented in Summary of Single-Shell Tank Waste Stability, WHC-EP-0347, March 1991, which evaluates several issues. The evaluation was done by reviewing the issues and conclusions in the Summary Report and determining if the conclusions would be changed if some of the waste was as low as pH 6. This evaluation only considered the safety significance of a lower pH, it did not reevaluate the original work and conclusions reported in the March 1991 document. No changes with safety significance were found.
