to reflect the latest requirement in the Tank Waste Remediation Privatization Request for Proposals (RFP) and amendments, The updated plan develops the sequence and transfer schedule for retrieval of DST supernate by the management and integration contractor and delivery of the staged supernate to the private low-activity waste contractors for treatment. Two DSTs are allocated as intermediate staging tanks. A transfer system conflict analysis provides part of the basis for determining transfer system upgrade requirements to support both lowactivity and high-level waste feed delivery. The intermediate staging tank architecture and retrieval system equipment are provided as a planning basis until design requirements documents are prepared. The actions needed to successfully implement the plan are identified. include resolution of safety issues and changes to the feed envelope limits, minimum order quantities, and desired batch sizes.
