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.

RP3C Community of Practice’s fifth anniversary
In February, the Community of Practice (CoP) webinar series, hosted by the American Nuclear Society Standards Board’s Risk-informed, Performance-based Principles and Policies Committee (RP3C), celebrated its fifth anniversary. Like so many online events, these CoPs brought people together at a time when interacting with others became challenging in early 2020. Since the kickoff CoP, which highlighted the impact that systems engineering has on the design of NuScale’s small modular reactor, the last Friday of most months has featured a new speaker leading a discussion on the use of risk-informed, performance-based (RIPB) thinking in the nuclear industry. Providing a venue to convene for people within ANS and those who found their way online by another route, CoPs are an opportunity for the community to receive answers to their burning questions about the subject at hand. With 50–100 active online participants most months, the conversation is always lively, and knowledge flows freely.

Specimens of SYNROC B were fabricated under a variety of conditions and doped with simulated radwaste species. Two of the component phases of SYNROC B, perovskite and zirconolite, doped with strontium and uranium, respectively, were also fabricated. All specimens were carefully characterized for both phase content and dopant partitioning via x-ray diffraction and electron beam microanalysis techniques. These specimens were then subjected to neutron activation and leached, and the leachant was analyzed by gamma spectrum analysis. All data were compared with similar analyses of Pacific Northwest Laboratory glass 76-68, a borosilicate glass. It was found that both perovskite and properly prepared SYNROC B leach at about the same rate as the borosilicate glass, while zirconolite appears to be at least an order of magnitude more resistant to leaching. When SYNROC is prepared under undesirable conditions and contains Ba2Ti9O20, cesium leach rates are one to three orders of magnitude higher than in the correctly composed SYNROC B.
