ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

DOE renews Portsmouth grant to Ohio University
The Department of Energy’s Office of Environmental Management has renewed a $2.5 million grant to Ohio University to support community redevelopment around the DOE’s Portsmouth Site. Since 2016, the DOE has provided a total of $8.2 million to the university for work with the communities.
The DOE grant, which began on October 1, will be administered over five years through September 30, 2027. A previous grant expired on September 30.

Tritiated wate`r production is ubiquitous in facilities that handle tritium gas. Sources range from decontamination efforts, to the deliberate conversion of elemental tritium to tritiated water in processes that strive to reduce emissions to the environment, to gaseous effluents to the environment. At low concentrations, ranging from a few μCi/L to mCi/L, high throughputs are required to process the high-volume, low-activity water. Combined electrolysis and catalytic exchange (CECE) shows promise by offering high throughput, reliability, economic viability, and facile coupling to isotopic separation systems if necessary. This paper will discuss the features of two production-scale CECE facilities: a 7 m3/h throughput system that uses an alkaline electrolysis cell and a 21 m3/h throughput system that uses a proton exchange membrane electrolysis cell. The former is in service and has been modified to improve reliability; the latter is in the initial stages of commissioning.
