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 International Thermonuclear Experimental Reactor (ITER) is designed to operate in two phases; physics and technology. The prime function of the shield is to protect the TF magnets. The predominant radiation limits are the nuclear heat load to the magnet and the end-of-life dose to the electrical insulator. These limits are specified by the magnet designers as 65 kW and 5×109 rads. Detailed shielding analysis has been performed and necessary machine modifications have been proposed during the conceptual design phase (1987–1990) in order to meet the magnet radiation limits. The shield is designed to satisfy the neutronics, thermal hydraulics, and mechanical design requirements. The reference shield consists of 316 SS structure and water coolant. A 5 cm thick back layer with special materials, such as W, Pb, and B4C, is considered outside the vacuum vessel to reduce the magnet damage. Two regions with critical shielding space are identified in ITER, the inboard and divertor regions. This paper presents the various options for the shield design based on a variety of shielding materials and summarizes the different analyses carried out to guide the shield design.
