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.

Current burnable absorbers such as boron carbide placed in the control rod guide tubes of fresh fuel assemblies create a water displacement penalty at end of cycle (EOC) that reduces the overall maximum cycle length of the reactor. Other burnable absorbers such as gadolinium-oxide mixed in the fuel do not create the water displacement penalty but create a lower centerline melt temperature for the fresh fuel and reduce the overall enrichment for the assembly. This research proposes using a transuranic (TRU) isotope with a relatively high absorption cross section such as 240Pu to reduce excess criticality within the reactor at beginning of cycle. The added benefit of using this TRU isotope over a standard burnable absorber is that when it absorbs a neutron it no longer negatively affects the criticality of the reactor, and it will transmutate into a fissile material that will add to the overall criticality of the reactor at EOC.
