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.

Typical materials and elements such as carbon steel, grease lubricant, electric cable and AC servomotor for the ITER remote maintenance equipment were exposed to a tritiated moisture environment to choose the appropriate materials from the viewpoint of tritium contamination / decontamination and to contribute to the structural and maintenance design of the remote maintenance equipment. After the test samples were exposed, the concentrations of tritium adsorbed on the samples were measured and decontamination experiments using gas purges with three different moisture concentrations were performed. It was found that metallic oxidized layer (Fe3O4 coated on S45C, slightly rusted SS400, rusted Cu of electric connector of the AC servomotor) adsorbs larger amount of tritiated moisture. Grease lubricant was highly contaminated in proportion to the exposed surface area of the pasted layer. Cable jacket (cross-linked polyethylene) was also highly contaminated in spite of hydrophobicity. This is probably because the jacket contains the filler “white carbon (SiO2·nH2O)” which adsorbs large amount of moisture. Internal parts of the AC servomotor were contaminated in the same level as the outer surface, because tritiated moisture goes into the inside through the sealing gap between casing and brackets.
