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.

This paper proposes a fuzzy method of evaluating horizontal nuclear proliferation risk for more efficient use of the International Atomic Energy Agency's (IAEA's) integrated safeguards (IS). The nuclear proliferation risk Rj of nation j is defined as (1 - j) × (1 - j), where j is the probability of nation j maintaining only peaceful nuclear activities for at least 1 yr, is the probability that the IAEA's IS detect indicators of nuclear explosive device (NED) acquisition activities, and j is the probability that the international community will force nation j to abandon these activities after the indications are detected.Because j is equal to and replaces the concept of nuclear nonproliferation credibility used in previous studies, this paper uses a method of deriving this credibility and converting it into j, which is evaluated using trapezoidal fuzzy numbers. Case studies of four nations currently under the IS reveal that the probability of IS detection of indicators of NED activity can be reduced by several tens of percent for some countries without exceeding the upper limit of horizontal nuclear proliferation risk that the international community had accepted in the past.Therefore, depending on the value of nuclear proliferation risk determined using the fuzzy method, the IAEA will be able to use its limited resources efficiently by reducing unnecessary expenditures for some nations under the IS and reallocating those resources to inspections of other nations without increasing the risk of proliferation.
