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 radiochemical reactions between methane and tritium were vicariously chosen for the evaluation of an omegatron type mass spectrometer and a laser Raman spectrometer in view of their analytical application in tritium systems. Assessment of the omegatron was extended beyond previous work on the quantitative analysis of all hydrogen isotopes and stable helium isotopes to include the determination of tritiated hydrocarbons. As opposed to mass spectrometry, laser Raman spectroscopy is an absolute method, which in principle is applicable to all polyatomic gases. For the employment in tritium systems an uhv-tight stainless steel gas cell using windows mounted in CF flanges with a flatness better than 1 lambda was constructed and tested. The Raman spectra of H2, HD and D2 were measured and the pure rotation and rotation vibration branches assigned. The fundamental vibrations of methane and deuterated methanes have also been identified. First kinetic data on the β-radiation induced exchange reaction between tritium and methane have been obtained with an omegatron.
