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.

Intensities observed from any sample can be reduced to any desired matrix by using interference free off-peak background as an internal standard. The normalized count IN is given by (Ip/IB) X B’, where Ip and IB are observed peak and background counts and B’, the normalization factor, is the background in the desired matrix. After blank corrections, the relation between the concentration and the intensity is IN = kC (for low concentrations), log IN = a log C (for intermediate concentrations), and log IN = a log C -b(log C)2 (for high concentrations), except when B’ is too small or too large. Adjustment of B’ is equivalent to altering experimental conditions. The second-degree curve can also be linearized by plotting log IN = log IN + b(log C)2 versus log C, or (log IN/ log C) versus log C. Analysis can be done by evaluating a and b from two standards and solving for log C. Transformation of this second-degree equation to the Siedel-Lomakin type of curve, the use of x-ray fluorescence as an absolute method of analysis without standards, with only the unknown sample and two dilutions, and the modification of influence coefficient method of Rasberry and Heinrich to a binary form consisting of only the element of interest and the matrix, all showed that such a unified approach enables analysis of all types of samples with standards in any available matrix.
