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.
Division Spotlight
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.

NuScale Energy Exploration Center opens at SC State
NuScale Power Corporation’s latest Energy Exploration (E2) Center has opened at South Carolina State University, in Orangeburg. E2 Centers are designed to provide visitors with hands-on experiences in simulated scenarios of operations at nuclear power plants. NuScale has established 10 such centers around the world. The company officially presented the fully installed E2 Center to SC State on May 21, after a collaborative setup and training process was completed.

The characterization of radioactive corrosion products deposited on the internal surfaces of recirculation pipes was carried out to determine the deposited amounts and configurations. The test specimens were taken from the auxiliary pipes of the recirculation lines of Shimane Nuclear Power Plant after operation for ∼20 000 effective full-power hours. As a result of characterizing them, it was demonstrated that 60Co, which determined the contact dose rate, was difficult to remove by mechanical washing the amount of 60Co deposited was reduced by more than a factor of 10 by oxalic acid polishing and by a factor of ∼1000 by electro-polishing both the particle size and 60Co specific activity of the deposits removed by the mechanical washing (designated as soft deposits) were the same as those of the crud suspended in the reactor water the 60Co specific activity of the deposits removed by the oxalic acid polishing (designated as hard deposits) was ten times greater than that of the suspended crud. It was inferred that the soft deposits were formed by direct deposition of the suspended crud, and the hard deposits were formed by oxidation of the stainless-steel base metal with 60Co being taken into the oxide layers.
