Impacts of Updated GSA Groundwater Flow Models on the FTF, HTF and SDF PAs
- Savannah River National Lab (SRNL), Aiken, SC (United States)
Savannah River Remediation (SRR) requested that the Savannah River National Laboratory (SRNL) evaluate the impacts of an updated General Separations Area (GSA) groundwater flow model on the F-Area Tank Farm (FTF), H-Area Tank Farm (HTF) and Saltstone Disposal Facility (SDF) Performance Assessments (PAs)1. For each facility, PORFLOW simulations were performed using both the 2004 GSA/PORFLOW (i.e., GSA_2004) and GSA2016 (i.e., GSA_2016) flow models. Overall, GSA_2004 and “_reference” (i.e., the archived data) results are practically identical, indicating GSA_2004 simulations reproduce the archived data very well. Compared with GSA_2004 data, the PEST.47 GSA_2016 results (with PORFLOW harmonic averaging at cell faces and diagonal terms in the dispersion tensor) support the following findings.
