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.

Mineral and synthetic oils used as lubricants or operating fluids in pumps are mixtures of branched or cyclic saturated hydrocarbons. They are chemically inert but their slow partial oxidation is possible even at room temperature. Specific activity of pump oils contacted with gaseous tritium for a long time may exceed 1013 Bq/kg.Studies of waste oils show that more than 90% of the radionuclide is bound with oxidation products. This selectivity is owned to predominant formation of quasifree tritons or 3HeT+ ions when one of the two nuclei in the T2 molecule decays. The sequence of ion-molecule triton transport reactions is the mechanism responsible for accumulation of tritium by oxidation products with higher proton affinity.The most effective technique of oil decontamination is adsorption of tritiated species by polar adsorbents (silica gels, zeolites). The detritiation degree for these adsorbents amounts to 95%. Then complete thermal oxidative destruction can be used to convert adsorbed organic compounds into CO2 and water. Thus, adsorption, thermal oxidation and adsorbent regeneration may be proposed as the technology of tritium recycling since HTO returns to the isotope separation system. As a result, the radiation danger related with storage of high activity waste oils can be significantly decreased.
