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.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

An imaging spectroscopy becomes one of the fundamental method of the radial profile study of the light impurities line emission of high temperature plasmas. The application of the spherical dispersion elements (as diffraction grids and a multilayer mirrors) makes it possible an image of the radial profile of the chosen spectral line intensity.
The line spectrum measurements of the light impurities emission in 50 - 200 nm wavelength range at different plasmas equipment (tokamak CASTOR and GOL-3) has been provided by Seya-Namioka spectrometer equipped by spherical diffraction grid and a two dimensional detection system. The especial arrangement of the optical trace has been used for high imaging resolution in plasma radial direction.
The novel diagnostic method can provide the way of impurity transport investigation [1]. It is well known, the transport effects lead to some deviations of the radial distribution of the line emission density from those calculated using pure coronal equilibrium. They can be deduced from chordal measurements of the radial profiles of the spectral line intensity and or intensity ratios of spectral lines of different ionisation stages both measured by chord-integrating spectrometer.
