This book was released on 1972 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: The anodic dissolution of uranium dioxide is shown to occur as a two-electron process with a current efficiency of 100 per cent in both acidic perchlorate and alkaline carbonate solutions. The effects, on the anodic dissolution process, of pH, temperature, and the various anions known to be present in commercial leaching solutions, were studied by the use of stationery potentiostatic measurements. The effects observed are interpreted in terms of the nature and properties of both the uranium dioxide surface and the primary products of oxidation.

Available in PDF, EPUB and Kindle. Book excerpt: Understanding of the long-term dissolution of waste forms in groundwater is required for the safe disposal of high level nuclear waste in a geologic repository, because waste-form radionuclides could be released by dissolution and transported in groundwater. The dissolution of the uranium dioxide (UO2) matrix in spent nuclear fuel is considered the rate-limiting step for release of radioactive fission products. The intrinsic UO2 dissolution rate sets an upper limit on the aqueous radionuclide release rate. Unsaturated spent fuel tests have shown that pH's of leachates have decreased to a range of 4 to 6, presumably due to air radiolysis that oxidizes nitrogen, producing nitric acid. Dissolution rates under such acidic conditions may be different than those previously reported for alkaline groundwater conditions. No dissolution rate measurements of UO2 or spent fuel have been reported for acidic conditions possibly relevant to a geologic repository. The purpose of our work has been to measure the intrinsic dissolution rates of uranium dioxide under acidic conditions that are relevant to a repository and allow for modeling. Experiments have been completed at room-temperature and 75 C, pH's of 4 and 6, and air and oxygen saturated aqueous solutions. These are compared with earlier work on spent fuel and UO2 using alkaline solutions.

Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive overview on the chemical thermodynamics of those elements that are of particular importance in the safety assessment of radioactive waste disposal systems. This is the first volume in a series of critical reviews to be published on this subject. The book provides an extensive compilation of chemical thermodynamic data for uranium. A description of procedures for activity corrections and uncertainty estimates is given. A critical discussion of data needed for nuclear waste management assessments, including areas where significant gaps of knowledge exist is presented. A detailed inventory of chemical thermodynamic data for inorganic compounds and complexes of uranium is listed. Data and their uncertainty limits are recommended for 74 aqueous complexes and 199 solid and 31 gaseous compounds containing uranium, and on 52 aqueous and 17 solid auxiliary species containing no uranium. The data are internally consistent and compatible with the CODATA Key Values. The book contains a detailed discussion of procedures used for activity factor corrections in aqueous solution, as well as including methods for making uncertainty estimates.

Download or read book The Chemistry of the Actinides written by S. Ahrland and published by Elsevier. This book was released on 2016-06-07 with total page 661 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of the Actinides contains selected chapters from the Comprehensive Inorganic Chemistry to meet the needs of certain specialists in this field. The book describes the 14 elements after actinium in the Periodic Table, known as the actinide elements or the 5f transition series. The book notes the occurrence, separation, chemical properties, chemical structures, and preparation of the metals. In a discussion of analytical chemistry, the radioactive properties of the actinides and the lanthanides are compared. The text then describes the nuclear or radiochemical records and chemical properties of the different members of the actinide series such as thorium, uranium, plutonium, and einsteinium. The book also explains the differences between the 5f shell and the 4f shell. One paper then discusses the groups of alloy compounds, including rare earths and intra-actinides. Another paper examines the general properties of actinide ions as to their electronic structure and oxidation states; the stability and preparation of the different oxidation states; and the applicability of solvent extraction in separating and purifying various substances. The text is suitable for researchers in organic chemistry, nuclear and atomic physicists, scientists, and academicians whose work involves radioactive materials.
