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.

Argonne’s METL gears up to test more sodium fast reactor components
Argonne National Laboratory has successfully swapped out an aging cold trap in the sodium test loop called METL (Mechanisms Engineering Test Loop), the Department of Energy announced April 23. The upgrade is the first of its kind in the United States in more than 30 years, according to the DOE, and will help test components and operations for the sodium-cooled fast reactors being developed now.

The purpose of the present study is to develop an accurate and practicable method to estimate an internal dose after exposure to tritium in various chemical forms. In rats exposed to tritiated water (HTO) or some tritiated organic compounds by single ingestion, the concentrations of total tritium and organically bound tritium (OBT) in blood and various organs were determined at various time intervals after ingestion. The concentrations of total tritium in blood showed a tendency to be higher than those in the majority of organs. When the cumulative doses to blood and organs for 100 days after ingestion of various tritiated compounds were compared, the doses to blood were almost the same or higher as compared with the maximum doses to organs. These results indicated that blood analyses would be useful to estimate a maximum of internal doses for exposure to tritium in various chemical forms. It was also suggested that the concentration ratio of OBT to total tritium in blood could be used to deduce the chemical form of tritium at exposure and the elapsed time after exposure.
