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.

A theoretical model using a heat and mass transfer analogy was developed to investigate the effects of noncondensable gases on the heat transfer coefficient of steam condensing inside a vertical tube. The Nusselt and Sherwood numbers in the gas phase were modified to incorporate the effects of condensate film roughness, suction, and developing flow. The model predictions showed good agreement with the experimental data obtained for various experimental conditions. A parametric study was conducted using the model with condenser tube diameter as a variable. The results indicated that the effects of noncondensable gases become weak as the inlet mixture Reynolds number (Remix,in = 4[over dot]mmix,in/dimix,in) increases and inlet noncondensable gas mass fraction (Wnc,in = [over dot]mnc,in/([over dot]mnc,in + [over dot]mv,in)) decreases. In addition, the effects of noncondensable gases also become weak as the condenser tube diameter decreases with the same inlet mixture Reynolds number because of interfacial shear stress.
