【 摘 要 】

The U.S. Department of Energy is formulating plans to vitrify the 204,400 m3 of radioactive waste contained in the 177 waste storage tanks at the Hanford Site in Washington State. Interim Hanford high-level waste glass TL models for use in the site flowsheet software are currently being updated (Vienna et al. [2001]). An integral part of this approach involves fabrication and testing of specific properties for glasses that adequately cover the compositional region of interest. As a result, Pacific Northwest National Laboratory (PNNL) developed a 45-glass test matrix (referred to as the SPA glass test matrix or SPA glasses) for which liquidus temperature (TL) will be measured. The Savannah River Technology Center (SRTC) is supporting PNNL efforts by (1) fabricating the SPA glasses and (2) analyzing their chemical composition.
