This report is the deliverable M2SF-18SN010305026 FY18 Summary Update on the Feasibility of Direct Disposal of SNF in Existing DPCs. It reports on work done throughout fiscal year (FY) 2018, on work planned at the beginning of that FY, consisting of R&D activities for: 1) injectable fillers that could be used in dual-purpose canisters to prevent postclosure criticality in a geologic repository, and 2) as-loaded DPC data gathering and criticality. The work reported here was performed by Sandia National Laboratories and Oak Ridge National Laboratory. Appropriate attribution to source documents is provided in the text, tables, and figures below. Additional R&D on direct disposal of existing DPCs was planned and funded in mid-FY, and the associated reporting is separate from this milestone. Additional discussion of that new scope and how it implements findings from an independent expert review of the fillers R&D program (Section 10) is provided in the Summary (Section 11).
