Radiochemistry and Nuclear Chemistry: Fourth Edition
- 2013
-
Book (other academic/artistic)abstract
- Radiochemistry or nuclear chemistry is the study of radiation from an atomic and molecular perspective, including elemental transformation and reaction effects, as well as physical, health and medical properties. This revised edition of one of the earliest and best-known books on the subject has been updated to bring into teaching the latest developments in research and the current hot topics in the field. To further enhance the functionality of this text, the authors have added numerous teaching aids, examples in MathCAD with variable quantities and options, hotlinks to relevant text sections from the book, and online self-grading tests.

Reducing the Long-term Hazard of Reactor Waste through Actinide Removal and Destruction in LWR's
- 1980
-
In: Sep. Sci. Techn. ; 15:4, s. 799-824
-
Journal article (peer-reviewed)abstract
- Public opposition to nuclear power has focused on the long-term risks from reactor waste. In the Purex process used in Europe, this waste is a concentrated nitric acid solution containing all nonvolatile fission products and the actinides Np, Am, and Cm, plus smaller amounts of U and Pu.Techniques have recently been described which guarantee an absolutely safe containment of this high-active waste (HAW) for about 1000 years. At longer times, the risk to the biosphere is dominated by the actinides. If these actinides are isolated from the rest of the HAW and destroyed through nuclear incineration, the long-term risks of the HAW will be dramatically reduced.This paper presents a detailed scheme for removing the actinides from the Purex-HAW solution. In principle, the process consists of three different solvent extraction cycles, using HDEHP and TBP in three successive steps. The scheme has been tested on a synthetic HAW solution containing all fission products and actinides (except Z 96, Cm) using laboratory-scale mixer-settler batteries. Results from runs on old Purex waste are also presented.If applied to fresh Purex waste, the process will encounter problems due to radiation damage to the reagents. In practice, this difficulty can be circumvented by using short contact times in the solvent extraction process. Extremely rapid multistage solvent extraction separations can be carried out by the SISAK technique (i.e., batteries of static mixers and special centrifugal separators). This technique is also described.

SISAK - A New Technique for Rapid Continuous (Radio)chemical Separations
- 1974
-
In: Journal of Inorganic Nuclear Chemistry. ; :36, s. 2397-
-
Journal article (peer-reviewed)abstract
- SISAK, a new continuous technique for on-line chemical separation of short-lived species, is presented. The system features multistage two-phase liquid-liquid and liquid-solid separations completed within 3–5 sec per stage. The system is easily adaptable for selective isolation of almost all elements. The operational characteristics of the system are outlined and the delay properties briefly discussed. A two-detector delay method for half-life determinations is also presented. The application of the technique to the study of short-lived nuclides is exemplified by results from investigations of 30 sec 68gCu, 3·8 min 68mCu and 42 sec 70Cu.
