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.

An apparatus was developed that utilizes light ions to simulate the effect of a fusion reactor first wall environment on the creep properties of metals and alloys. The creep apparatus includes a wire specimen stressed in the torsional mode. Rotation or strain is measured by an optically coupled photocell tracking system. Temperature control of the specimen is obtained by varying the temperature of flowing helium passing perpendicularly across the specimen. The initial study involved bombarding a 20% cold-worked AISI Type 316 stainless-steel specimen at 400°C with 14.8-MeV protons at a beam intensity of ∼10 µA/cm2 or a displacement rate of ∼3.4 × 10−7 dpa/s. The accelerator was operated intermittently to accumulate 130 h of beam time and a total dose of ∼0.2 dpa. Strain rates on the order of 5 × 10−4% shear strain per hour were observed during irradiation, whereas negligible strain rates were observed when the accelerator was turned off. On a dpa basis, proton-induced irradiation creep rates were approximately one order of magnitude higher than those observed in fast reactor neutron irradiations of the same materials under similar conditions.
