WRPS is managing 56 million gallons of radioactive waste at Hanford. Their mission is to safely handle the waste, develop retrieval tools, and prepare for processing at the Waste Treatment Plant. Vitrification turns the waste into glass to contain radioactivity. Retrieval is challenging due to the waste's complexity and limited tank access. New technologies like enhanced-reach sluicing and the Mobile Arm Retrieval System are being used for waste retrieval. The infrastructure at Hanford's tank farms was modernized with funding from the American Reinvestment and Recovery Act.
