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.

Constellation seeks rezone for property adjacent to Illinois plant
While no development details have been released, Constellation is asking to rezone 658.8 acres of land it owns around the Byron nuclear plant in Illinois for possible long-term use.

Finite element analysis calculations are performed to determine the temperature profile in sections of the ITER Electron Cyclotron Heating (ECH) transmission line waveguide. Each aluminum, corrugated waveguide transmission line will transmit up to 1.5 MW of electromagnetic radiation over roughly 200 meters from a 170 GHz gyrotron to heat the plasma in the tokamak. The “ridged tube” waveguide has integral water cooling traces which are lined with copper tubing. Each transmission line includes miter bends which may be actively cooled and waveguide couplings, where the waveguide cannot be actively cooled due to coupling hardware. The amount of cooling water available is limited, so determining the required amount of water in the cooling lines is essential. Finite element computational analyses are performed to determine the effect of the heat load and water cooling on the temperature profile of the waveguide in various steady-state cases.
