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.

PPPL study points to better fusion plasma control
The combination of two previously known methods for managing plasma conditions can result in enhanced control of plasma in a fusion reactor, according to a simulation performed by researchers at the Department of Energy’s Princeton Plasma Physics Laboratory.

This study was conducted to explore the feasibility of rapid setting cement (RSC) as an agent of immobilization for certain elements such as fission products or radioactive materials through evaluation of the setting time, apparent porosity, bulk density, pH value, conductivity, compressive strength, and compositions. Two different cylindrical sample groups were created. The first group was a mixture of the cement powder with deionized water (DIW) and different concentrations of Ce (0, 2, 5, 7.5, and 10 wt%). The second group included the cement powder, artificial seawater (ASW), and same Ce concentration patterns. Samples were analyzed by X-ray diffraction (XRD), fluorescence analysis (XRF), and scanning electron microscopy including energy-dispersive X-ray spectroscopy. The results showed that the final setting time and compressive strength of RSC with both solutions (DIW and ASW) decreased as Ce content increased while opposite trends were observed for the apparent porosity and bulk density of RSC under the same concentration effect. As salt contents increased, the pH decreased while the conductivity increased gradually. The XRD patterns revealed that two newly identified phases were reported, namely CeAl11O18 and Ce4.667 (SiO4)3O. The XRF results showed uniform distribution of Ce concentrations within RSC with both solutions (DIW and ASW). The morphology of matrix samples showed that the existence of Ce distributed on the pore wall or clustered with Si, Al, Mg, K, P, Fe, and O.
