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 SIGMA technology, a patented new concept for uranium enrichment based on the well-known gaseous diffusion (GD) method, has been developed by the Comisión Nacional de Energia Atómica in Argentina to be an alternative to compete in the uranium enrichment market. The SIGMA engineering approach stands on the integration of several GD stages in one module, with all the stages sharing one single multiflux compressor, one vessel, and a gas turbine. This arrangement, together with the use of the double-diffuser cascade configuration to increase the separative gain, leads to a breakthrough in the capital cost structure of the GD technology and a significant reduction in the energetic and operation costs. With the SIGMA concept, a leveled separative work unit cost that could be almost half the price of the present enrichment market level can be achieved. The SIGMA technology has also been conceived to incorporate proliferation-resistant features, and it has a very small overall proliferation risk. In this work we present the main features of the SIGMA technology, and we formulate a calculation scheme for the overall design analysis. We present some of the results of this investigation, including the SIGMA scale economy, and its comparison with others enrichment technologies.
