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.

NRC engineers share their expertise at the University of Puerto Rico
Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

A design and performance test of an antiscattering X-ray grid that is based on photosensitive glass was conducted using MCNP simulation. The simulation was designed in three parts: source, scatterer, and grid. The source was a cone type with a single energy of 50 keV, and the scatterer was designed as a box with elemental composition and density the same as those of a human body. Three types of grid were tested: ideal, injection, and electroplating. The ideal-type grid was generally known and contained only a shielding wall, the injection-type grid had the shielding material injected into the glass, and the electroplating-type grid had the shielding material electroplated on the glass lattice skeleton. The ideal-type grid showed a scattered and primary photon ratio (SPR) of 0.106, and the nongrid type showed an SPR of 0.159. The injection-type grid had an SPR of 0.126, which corresponded to 119.3% of that of the ideal type. The electroplating-type grid had an SPR of 0.0964, which corresponded to 93.7% of that of the ideal type. It was understood that the electroplating-type grid showed the most effective reduction of the scattered photons in terms of SPR.
