Impact of phenylborate compounds on a cement-based waste form
The Saltstone Facility provides final treatment and disposal of low level liquid waste streams at the Savannah River Site (SRS). Saltstone is formed by mixing salt solution with cement, flyash, and slag to form a grout, which is pumped into large concrete vaults where it cures. The facility started radioactive operations in June 1990. As new waste treatment processes start at the Savannah River Site, the Saltstone Facility feed will change and include phenylborate compounds (tetraphenylborate, triphenylboron, diphenylborinic acid, and phenyl boric acid). SRTC performed tests to determine the effect of TPB, 3PB, 2PB, and 1PB on the Saltstone process. This document describes the relative contributions of TPB, 3PB, 2PB, and 1PB to benzene evolution, 28 day benzene TCLP results, and interactions between phenylborates and the saltstone dry chemicals. The benzene evolution tests were performed to provide the data needed to predict benzene evolution rates from the Saltstone facility. The TCLP tests were conducted to determine whether the waste containing phenylborates would be RCRA hazardous. The interaction tests were performed to identify plausible changes in the saltstone recipe which could reduce the benzene generation rate.
