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 University of Wisconsin–Madison inertial electrostatic confinement fusion device HOMER was used to perform current scans at low and moderate pressures, 0.3 and 1.0 mTorr of deuterium, in which the cathode voltage, current, and pressure were carefully controlled. The data was taken in short intervals to avoid the degrading effect of chamber heating on the fusion rate. Low pressure operation should harden the deuterium energy spectrum, but the low pressure also reduces target density. The results showed the fusion rates for 0.3 mTorr are about half that at 1 mTorr. Also, the 6 low pressure current scans had confirmed the approximately linear neutron production rates with respect to current. All 6 of the 1 mTorr current scans showed trends of slightly above linear neutron rates. Also, a new IEC steady state D-D neutron production record of 2.5 × 108 n/s was set at 150 kV, 100 mA, and 1.0 mTorr.
