The U.S. Department of Energy’s (DOE) Hanford Site houses 56 million gallons of high-level radioactive
waste generated from plutonium production from 1944 to 1988.1 The supernatant waste, currently stored
in underground tanks, is intended to be vitrified following filtration and 137Cs removal at the Hanford
Waste Treatment and Immobilization Plant (WTP) Low-Activity Waste (LAW) Vitrification Facility. The
WTP Pretreatment Facility will not be operational for several years. The Tank Side Cesium Removal
(TSCR) system is a technology demonstration that will remove cesium from tank waste supernate to
support directly feeding LAW to the vitrification facility. The 137Cs removal is important to meet the
WTP LAW contract specification and ultimately for creating a contact-handled waste form. The waste
acceptance criteria (WAC) limit for the WTP LAW Facility is
