“…Lysimeters were constructed according to an established method (Kaplan et al, 2018;Kilgo, 2018;Peruski et al, 2018;Roberts et al, 2012) at the Radionuclide Fate and Transport Experiment (RadFATE) facility at Clemson University (South Carolina, USA). Briefly, the setup utilized a 15 cm diameter PVC pipe that was ~72 cm in length.…”

“…• Three field lysimeter reports were issued in FY2018. The first report summarized findings regarding sorption/desorption of Np, Pu, Cs, Co, and other elements (Kaplan et al, 2018). The second report documented concentrations measured in field lysimeter effluents from the fourth quarter of FY2017 and the second quarter of FY2018 (Powell 2018a).…”

This document provides the Department of Energy (DOE) Order 435.1, Radioactive Waste Management (DOE 1999c) required Annual Review for the Savannah River Site (SRS) Composite Analysis (CA). Progress made to-date toward addressing the secondary issue from the LFRG review of the 2010 SRS CA has focused primarily upon inventory estimate improvements. Inventory impacts dose in a linear fashion and reduces the uncertainty with the CA conclusions. Maintenance items are addressed, as funding allows, based on the relative risk associated with meeting the performance objectives. Currently, there is minimal risk in exceeding the DOE 100 mrem/yr CA primary dose limit or the DOE 30 mrem/yr dose constraint (administrative limit). Proposed activities, discoveries, new information and changes potentially affecting the 2010 SRS CA are documented in this and earlier Annual Summary reports, and a consolidated list of changes since the 2010 CA is documented in this report. The impact to the CA of changes arising from these new PA baselines is expected to be minor for the following reasons: The primary contributors to the SRS CA dose impact at the UTR POA are the H-Canyon and Mixed Waste Management Facility (MWMF), contributing 68% and 9%, respectively, to the dose impact at that POA. The combined contribution to the UTR dose impact from all PA's (SDF, E-Area LLWF, FTF and HTF) is ~2% of this total. The 2010 SRS CA model validation performed indicates that the CA projected dose, while generally conservative, provides a reasonable representation of the maximum annual doses. Doses evaluated are well below the SRS established 15 mrem/yr administrative limit (Crapse et al. 2011). Based on the assessment presented within this annual review and collective engineering judgement, the conclusions of the 2010 SRS CA remain valid and there is reasonable assurance that SRS will meet the performance objectives delineated in DOE Order 435.1. The 2010 SRS CA should be updated to incorporate PA changes, proposed changes to inventories and sources and model improvements accumulated since the 2010 CA. The timing will be dependent on the completed of PA revisions.
