RICHLAND, Wash. — The EM Office of River Protection (ORP) and contractor Washington River Protection Solutions (WRPS) have completed the first waste processing campaign through the Tank-Side Cesium Removal (TSCR) System at the Hanford Site.

TSCR is a demonstration project which removes radioactive cesium and solids from tank waste and delivers low-activity waste to a nearby underground storage tank.

Richland Operations Office and Office of River Protection Manager Brian Vance congratulates Tank-Side Cesium Removal (TSCR) System workers following completion of TSCR’s first waste processing campaign.

The treatment system hit a milestone in December, processing more than 800,000 gallons of radioactive liquid waste since the campaign began. The TSCR team reached that goal after a record-short maintenance outage of only three weeks. In addition, TSCR removed over 99.99% of radioactive cesium from the processed liquid waste.

The waste is staged until it can be fed to Hanford’s Waste Treatment and Immobilization Plant for vitrification, or immobilization in glass. TSCR is a key component and the first step in Hanford’s Direct-Feed Low-Activity Waste Program to treat tank waste.
