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.

The RETRAN system thermal-hydraulics analysis code has been used to simulate the three turbine trip tests at the Peach Bottom Unit 2 boiling water reactor. The latest analysis used the dynamic slip, profile fit subcooled void, and point kinetics models in RETRAN-02. The results demonstrated that RETRAN is capable of simulating operational transients such as turbine trips. The analysis aided in understanding physical phenomena not well known such as the transient behavior of the steam bypass system and the pressure vessel. Experience gained in this work pointed out the importance of having good experimental data for code qualification purposes. This includes knowing the initial conditions, boundary conditions, control system and equipment parameters, and operator actions. The analysis of these three tests will be repeated in the future using one-dimensional kinetics, improved steam separator, and mechanistic subcooled voiding models.
