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.

The thermal properties of the pebble beds have a significant impact on the temperature profile of the Helium Cooled Pebble Bed blanket and the extraction of heat from the pebble beds to the coolant. The effective thermal conductivity of pebble bed has been modeled as the isotropic one. However, the isotropic thermal conductivity inherently can be achieved only the case with perfectly isotropic arrangement which is difficult to realized in the actual blanket device. In this paper, the relation between effective thermal conductivity tensor and fabric tensor in 2D pebble bed is investigated experimentally. It is cleared that the effective thermal conductivity tensor is proportional to the structural anisotropic tensor. And, the anisotropic feature is quite different between core region and near wall region, so that it is suggested that modeling of the effective thermal conductivity tensor of the pebble bed should be separately carried out at least in above two regions.
