Preparation and Testing of Glasses to Support Vitreous State Laboratory Development of WTP IHLW Formulation Algorithm
- The Catholic Univ. of America, Washington, DC (United States)
This report presents results from the High Level Waste (HLW) glass formulation testing performed at the Vitreous State Laboratory (VSL) of the Catholic University of America (CUA) to support the development of an immobilized high-level waste (IHLW) formulation algorithm for the River Protection Project-Hanford Waste Treatment and Immobilization Plant (RPP-WTP). The WTP Project is developing a IHLW formulation algorithm for calculating acceptable HLW glass compositions for the vitrification facility. The preliminary IHLW formulation algorithm (version 3) employs various property-composition models to implement the product quality requirements and key processing constraints on the calculated glass compositions. The primary objective of this work is to assess the acceptability of the glass compositions formulated by the preliminary algorithm. Specifically, this report presents testing results on glasses calculated by the formulation algorithm with respect to Product Consistency Test (PCT), melt viscosity, electrical conductivity, and one-percent crystal fraction temperature (T1%). Completion of the test objectives is addressed in the table below. Since the IHLW formulation algorithm is preliminary in nature and will be revised in the future with updated property-composition models, extremes in compositions and/or properties were preferred in glasses selected for testing in order to explore the boundaries and limitations of applicability of the algorithm.
