NASNF Processing and Packaging Technical Study

Abstract

The Accelerated Basin Deinventory (ABD) Program is designed to accelerate the deinventory of L-Basin and accelerate the SNF disposition mission. Spent fuel will be dissolved in H-Canyon with no recovery of Uranium-235 (U-235). The dissolver solutions will be temporarily stored, then transferred to the tank farms and immobilized in the Defense Waste Processing Facility. ABD accelerates basin closure, significantly reduces programmatic risk and greatly reduces the lifecycle budget requirements for the site by eliminating the need for a SNF drying and packaging project. The ABD approach represents a significant change to the clean-up approach for the Savannah River Site. The ABD Program requires changes in how H-Canyon is configured and operated. Revision viii
