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
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Canada clears Darlington to produce Lu-177 and Y-90
The Canadian Nuclear Safety Commission has amended Ontario Power Generation’s power reactor operating license for Darlington nuclear power plant to authorize the production of the medical radioisotopes lutetium-177 and yttrium-90.

In the Tohoku University Heliac (TU-Heliac), hot-cathode biasing experiment has been carried out. Poloidal Mach number exceeded unity, and reached 5 (supersonic regime). Increase of the electron density and decrease of the impurity influx were observed. It is important to study the anomalous transport for evaluation of the improvement. Then potential and density fluctuation (~600 kHz) measurement system were installed to the TU-Heliac. Characteristics of the fluctuations in the hot-cathode-biased supersonic plasma were measured. The fluctuation of (i) low frequency band (<10 kHz) and (ii) high frequency band (100~300 kHz) had large power spectra. The fluctuations between these bands (10~100 kHz) were suppressed. The potential fluctuation level was larger more than one order of the density fluctuation level in the low frequency band (<10 kHz), and comparable to the density fluctuation level in the high frequency band (100~300 kHz).
