Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Feinstein Institutes to research novel radiation countermeasure
The Feinstein Institutes for Medical Research, home of the research institutes of New York’s Northwell Health, announced it has received a five-year, $2.9 million grant from the National Institutes of Health to investigate the potential of human ghrelin, a naturally occurring hormone, as a medical countermeasure against radiation-induced gastrointestinal syndrome (GI-ARS).

Radioactive element separation is of particular interest in nuclear technology. For this purpose, batch experiments were carried out in order to find the best separation conditions of uranium [U(VI)] and thorium [Th(IV)] from aqueous solution using rice straw activated carbon. The influence of pH and contact time on selective adsorption of U(VI) and Th(IV) was investigated. The results indicate that the velocity of these species from liquid phase to the surface of carbon is rapid enough. The reaction rate was fast, requiring only a short contact time of 40 min for U(VI) and 100 min for Th(IV). Sorption reaches maximum at pH 4 for Th(IV) and at pH 5.5 for U(VI). U(VI) and Th(IV) can be separated by the judicious controlling of pH and contact time. They can be separated from each other at pH 4 with different contact time [Th(IV) at lower time and U(VI) at 200 min]. Studies were conducted to examine the change in the adsorption behavior of U(VI) and Th(IV) on adsorbent as a function of employing different complexing agents of mineral and organic acids that are important in industrial and environmental processes, including hydrochloric, nitric, acetic, sulfuric, and phosphoric acids at 0.1M concentration. Acetic acid enhances U(VI) and Th(IV) uptake compared to mineral acids. These procedures may be useful in the separation of U(VI) and Th(IV) from natural or industrial samples containing these elements.
