Development and Testing of a Glass Waste Form for the Immobilization of Plutonium

چکیده
Two alkali-tin-silicate (ATS) glasses have been prepared at Argonne National Laboratory (ANL) as part of our ongoing research in radioactive waste glass development. These glasses dissolved 5% and approximately 7% Pu. Early corrosion test results indicate that Pu-bearing ATS glass is extremely durable. The initial goal in this project concerned equally both the solubility of Pu and the durability of the ATS glasses; however, our primary emphasis has changed recently to maximizing the loading of Pu in the glass. ATS-based glasses, using Th(VI) and Ce(III) as surrogates for Pu(IV), are now being investigated to increase the solubility of Pu without substantially sacrificing the durability of the current ATS formulations. The solution data from various corrosion tests on the original Pu-containing ATS glasses are also presented.

Integrated Testing of the Srl - 165 Glass Waste Form
Integrated testing of the important components of a glass waste form waste package has been performed in order to gain a better understanding of the processes of radionuclide release and transport in the near field environment. Based upon an interpretation of the depth of penetration of hydrogen in reacted SRL-165 glass we have modeled the radionuclide release from the glass as a combined proce...
متن کاملStudy of immobilization of nano-TiO2 for environmental aspects on glass by different resin categories
TiO2 and especially its nano-metric structure have many applications for environmental proposes. It can be used in mobilized or immobilized status, but its consumption is less in immobilized form and its process would be economical. In addition, the environmental problems would be minimized. There are a few methods for immobilization of nano-TiO2 inside the process. The sol-gel method is typica...
متن کاملRadiation effects in crystalline ceramics for the immobilization of high-level nuclear waste and plutonium
This review provides a comprehensive evaluation of the state-of-knowledge of radiation effects in crystalline ceramics that may be used for the immobilization of high-level nuclear waste and plutonium. The current understanding of radiation damage processes, defect generation, microstructure development, theoretical methods, and experimental methods are reviewed. Fundamental scientific and tech...
متن کاملNuclear waste forms for actinides.
The disposition of actinides, most recently 239Pu from dismantled nuclear weapons, requires effective containment of waste generated by the nuclear fuel cycle. Because actinides (e.g., 239Pu and 237Np) are long-lived, they have a major impact on risk assessments of geologic repositories. Thus, demonstrable, long-term chemical and mechanical durability are essential properties of waste forms for...
متن کاملPlutonium Immobilization Project Cold Pour Phase 2 Test Results (u)
The Plutonium Immobilization Project (PIP) is a program funded by the U.S. Department of Energy to develop technology for dispositioning excess weapons grade plutonium. This program introduces the “Can-in-Canister” (CIC) technology that immobilizes the plutonium by encapsulating it in ceramic forms (or pucks) and ultimately surrounding it with high-level waste glass to provide a deterrent to re...
