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.

Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

The monoblock geometry is proposed for the ITER Physics Phase divertor for brazing of carbon armor tiles to copper or molybdenum cooling tubes. Elastic/plastic finite element analyses predicted high residual stresses except with OFHC copper. Samples of pyrolytic graphite tiles brazed to OFHC copper, Glidcop™ Al-15 copper alloy, and molybdenum tubing show cracking in all of the samples, except with the OFHC copper. A 3-tile divertor target consisting of 12 mm thick pyrolytic graphite brazed with a copper-silver alloy to a 12 mm diameter OFHC copper tubing was tested at 15 MW/m2 with a rastered 30 keV electron beam for 1000 thermal cycles. A gradual rise in surface temperature from 1000 C to 1200 C over the 1000 cycles was observed, along with hot stripes (1500 C) at the tile edges. However, no delamination cracks could be detected.
