Development and Testing of a Glass Waste Form for the Immobilization of Plutonium
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 durabili...
متن کاملCerium isomorphism and the – transformation in plutonium
We use the thermodynamic model introduced by Aptekar’ and Ponyatovskiy for the – transformation in cerium metal to study the properties f plutonium metal. The model describes the – transformation in Pu and explains the minimum in the melting versus pressure curves for both aterials. Ga stabilization of the -phase of Pu is explained in terms of a first order transition between the two phases. Th...
متن کاملRadiation Damage of a Glass-bonded Zeolite Waste Form Using Ion Irradiation
Glass-bonded zeolite is being considered as a candidate ceramic waste form for storing radioactive isotopes separated from spent nuclear fuel in the electrorefining process. To determine the stability of glass-bonded zeolite under irradiation, transmission electron microscope samples were irradiated using high energy helium, lead, and krypton. The major crystalline phase of the waste form, whic...
متن کاملPlutonium and uranium in Japanese human tissues.
Plutonium and uranium in human tissues obtained from residents of the Tokyo area were determined by a-spectrometry and the fission track method, respectively. The distribution pattern of each element was estimated on the basis of mean concentration obtained. Plutonium is concentrated in some special organs, while uranium is distributed rather generally throughout the whole body. This difference...
متن کاملSeparation of Technetium from Uranium and Waste Form Synthesis
In the Advanced Fuel Cycle Research & Development (AFC R&D) activities, the uranium extraction (UREX+1) process is proposed as one of the most promising technique to separate transuranic elements (TRU) from light water reactor spent nuclear fuel in the years to come. The isotope Tc will be separated together with U within the first process steps. After the separation of U, Tc must be immobilize...
