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.

Four million nuclear jobs by 2050: Who will do them?
Industry leaders from around the globe met this month to discuss the talent development that will be necessary for the long-term success of the nuclear industry.
The International Conference on Nuclear Knowledge Management and Human Resources Development, hosted by the International Atomic Energy Agency, was held in Vienna earlier this month. Discussed there was the agency’s forecast for nuclear capacity to more than double—or hopefully triple—by 2050 and the requirement of more than four million professionals to support the industry.

Predictions by RELAP5/MOD2 and RETRAN-02 are compared on a model of the Westinghouse model E steam generator, which is a U-tube steam generator with an integral preheater section. The model is the result of a detailed nodalization study performed with RETRAN to determine the minimum number of nodes (or control volumes) required in the secondary side to model the response of steam generator water level and primary-side exit (cold-leg) temperature during startup testing and operational transients. Five transients are used as forcing functions to generate the response of the steam generator. These transients were selected based on providing both nominal and severe forcing functions on the heat removal capability of the secondary side. The steam generator transients investigated were (a) loss of feedwater, (b) turbine trip, (c) decrease in load demand, (d) increase in load demand, and (e) decrease in inlet feedwater temperature. Steam line exit mass flow rate, secondary-side liquid mass inventory and water level, and primary-side cold-leg temperature predictions are compared with the RETRAN-02 results. Reasonable comparisons are obtained between the RELAP5 and RETRAN code predictions, as well as qualitative behavior of simulation experiments.
