Evaporation of Hanford Tank Sample AN-107 Mixed with Recycles

A proof-of-technology demonstration for the Hanford River Protection Project (RPP) Hanford Tank Waste Treatment and Immobilization Plant (WTP) was performed by the Savannah River Technology Center (SRTC) at the Savannah River Site (SRS). As part of this demonstration, a sample of as-received Tank AN-107 waste was mixed with surrogate recycle and then evaporated to concentrate the mixture. A second test was conducted in which surrogate recycle was initially concentrated, then mixed with as-received AN-107 waste. Both of these tests were the first studies conducted that investigated the potential impact of secondary-waste recycle streams on the evaporation process using actual radioactive waste feed.
