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.

Framatome, KHNP to investigate producing Lu-177 in South Korea
Framatome and Korea Hydro & Nuclear Power (KHNP) announced the signing of a memorandum of understanding to explore the possibility of producing the medical isotope Lutetium-177 at KHNP’s Wolsong nuclear power plant in South Korea. The companies also will investigate the feasibility of using the plant to support Korean production of medical radioisotopes in the future.

Modifications to the National Ignition Facility (NIF) Cryogenic Target Positioner (Cryo-TarPos) are needed to provide polar-drive-ignition targets; ideally, these modifications will be completed and tested by 2017, the earliest date anticipated for polar-drive-ignition experiments. The extent of these modifications is defined by the mechanical and thermal requirements needed for the target to conform to the ignition design and the capabilities of the existing equipment. This paper describes the design of the polar-drive target assembly and the surrounding cryogenic environment that meets many of the specifications and requirements for the ignition target. Further work is necessary to optimize the design and provide more-detailed guidance for modifying the NIF Cryo-TarPos; however, there is sufficient information to begin the redesign effort at the conceptual level.A specialized facility has been constructed to test different target assembly and cryogenic hardware designs. The equipment provides the mechanical and cryogenic functionality available at the NIF, making it possible to test different target designs with deuterium in a configuration suitable for integration with the NIF Cryo-TarPos. The polar-drive target assembly has demonstrated a stable ice layer (170 to 350 m thick) and the ability to control the thickness to ±3 m of the desired value. The target is rotatable to fully characterize the D2 ice surface using shadowgraphy and X-ray phase contrast. Thermal models of the target and its environment indicate that (a) it should be possible to achieve the desired 1-m root-mean-square smoothness using D-T, (b) the fill tube has little effect on the ice smoothness, and (c) it is possible to shape the isotherms surrounding the target sufficiently to form an oblate ice layer that may be more desirable for polar-drive implosions.
