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.

From South Korea to Belgium: Testing a high-density research reactor fuel
The Korea Atomic Energy Research Institute has developed a high-density uranium silicide fuel designed to replace high-enriched uranium in research reactors. Recent irradiation tests appear to be successful, KAERI reports, which means the fuel could be commercialized to continue a key global nuclear nonproliferation effort—converting research reactors to run on low-enriched uranium fuel.

Tritiated water (Q2O) is produced during fusion fuel purification or air detritiation. Before recovering the tritium by isotope separation, the Q2O needs to be reduced to form Q2 gas. The reduction of tritiated water on iron is an alternative to electrolysis and gas-shift reactors. It allows a simple, compact, configuration with low tritium inventory. The reactor design incorporates a palladium alloy permeator which extracts the Q2.
Tests on a commercial iron-based catalyst showed a high reactivity and no degradation with repeated cycling. The optimum temperature for water reduction was 375–395 C, and for iron regeneration using hydrogen, 470–495 C. The first prototype reactor-permeator decomposed 9.5 g water in 8 hrs using 210 g iron. The time needed for iron regeneration was reduced to 16 hrs by recirculating the hydrogen. A pilot-scale reactor permeator is now under development: it should be capable of reducing 35 kg of water per year, operating at 1 bar. Attention to the choice of structural materials will minimise tritium carryover into the water produced during regeneration.
