Tank waste remediation system phase I high-level waste feed processability assessment report

Glass Formulation Development for INEEL Sodium-Bearing Waste

“…to 60 mass YO was added to avoid nepheline precipitation in the glass.b Tfiically, a constraint on S03 concentration' would be used to avoid sulfate accumulation in the melter (Li et al 1995;Lambert et al 1996). However, the tests planned to demonstrate SBW processability include the use ofa melter with a salt drain that will tolerate salt separation.d Therefore, no constraint on salt separation from glass was used for SBW glass foirnulation (i.e., salt formation will not limit waste loading).…”

“…The primary difference appears to be in the SOSconcentration. This will impact the formation of a secondary salt phase since the volubility of SOS is expected to be roughly 1 mass 'Yo (Li et al 1995, andLambert et al 1996). q at 1150°C (using the 3rdand 4* columns of Table 2.2) 6.0 (P&S) 5.9 (Pas) r~, (using the 5* column of Table 2.2) 0.9 (g/m*) 0.8 (g/m*) r~(using 6* column of Table 2.2) 1.0 (g/m2) 1.0 (g/m*)…”

Phase I high-level waste pretreatment and feed staging plan

“…Empirical glass property models have been developed by Pacific Northwest National Laboratory (PNNL) that estimate glass volumes are reduced by more than 30 percent by caustic leaching (Lambert and Stegen 1996) when allowing greater than 25 wt% loading. This information is considered preliminary, and may affect a future revision of this plan.…”

“…This study is part of an integrated effort that includes the following documents: (Certa et al 1996) Operational Waste Volume Projection (Koreski and Strode 1996) Initial Retrieval Sequence and Blending Strategy (Penwell et al 1996) Neutralized Current Acid Waste Consolidation Management Pian (Powell 1996) Tank Waste Remediation System Phase I High-Level Waste Feed Processability Assessment Report (Lambert and Stegen 1996) Decision Document for Phase I Privatization Transfer System Needs (Galbraith et al 1996) TWRS Privatization Process Technical Baseline (Orme 1996).…”

“…In the first case, Lambert and Stegen (1996) estimate that no significant product volume reduction will be incurred by caustic leaching either of the AZ tanks. In the case of 102-AY/106-C, however, a product volume reduction in excess of 30 percent might be expected.…”
