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.

College students help develop waste-measuring device at Hanford
A partnership between Washington River Protection Solutions (WRPS) and Washington State University has resulted in the development of a device to measure radioactive and chemical tank waste at the Hanford Site. WRPS is the contractor at Hanford for the Department of Energy’s Office of Environmental Management.

In this study, tritiated water was poured in a packed bed of natural soil and subsequently distilled water was poured in the bed to recover tritium retained in the soil at room temperature. From tritium balance, 22.5 % (7.1 MBq) of input tritium (31.5 MBq) was retained in the soil bed. By distilled water purge, 70 % (5 MBq) of retained tritium was recovered but 30% (2.1MBq) was left. To recover residual tritium, the soil was immersed in distilled water for 531 days but the amount of tritium released to distilled water was slight (0.04 MBq). A part of the soil immersed in the water was taken out and heated up to 300°C under humid oxygen atmosphere. Tritium release terminated at about 50 hours. 11 % (0.23 MBq) of retained tritium was released. By heating to 1000°C, the release amount of tritium increased proportionally to the time and additional 4% (0.09 MBq) was released at 5 hours. The desorption rates of tritium in each process was quantified.
Tritium is quite slowly released from the natural soil exposed to tritiated water in water at room temperature. However, a long time heating by 1000°C would be required to try to recover all tritium from the contaminated soil positively, although tritium recovery was not completed in this work.
