Title: Complexant stability investigation. Task 2. Organic complexants

Abstract

The safety of high-level defense waste operations has always been given highest priority at the Hanford site. This document is part of the continued effort to appraise and reevaluate the safety of the waste stored in underground tanks on the Hanford Reservation. Hanford high-level defense waste consists mainly of moist, inorganic salts, NaNO/sub 3/, NaAl(OH)/sub 4/, Na/sub 2/CO/sub 3/, and other sodium salts. However, in addition to these salts, quantities of organic compounds constitute a significant portion of the waste. The potential reaction of the organic compounds with inorganic salts to form explosive substances is examined and found to be nonexistent or negligible. The concept that the waste mixture might react exothermically is found to be untenable under the present storage conditions. The phenomenon of slurry growth in double-shell waste storage tanks is expected to cause no increase in exothermic reaction potential within the waste. The results of this study indicate that the presence of organic material in the high-level defense waste does not constitute undue hazard under the present storage conditions.
