Recently, a colleague related to me a conversation overheard at an industry forum in which ANS was referred to as a group of “academics” who were of limited use in expanding the workforce needed to deliver a nuclear resurgence.
While not new, this criticism still gets me hypertensive when I hear it. Many still see ANS as a bunch of academics and “labbies” disconnected from the day-to-day commercial nuclear race.
Yet, I also understand the charge is not entirely without foundation. Pop your head into a technical session at an ANS national conference, and you’re bound to hear academics presenting research that, to nontechnical ears, sounds esoteric.

A model for steam condensation in the presence of non-condensable gases is developed in the CFD package ANSYS CFX 16.1. Based on the Euler-Euler two-fluid approach, this model considers two different phases: a continuous gas phase, which is a mixture of air and steam, and a disperse liquid phase consisting of water droplets. Using the data of the CONAN test facility, the numerical error is quantified using the Grid Convergence Index method. The simulation results are then validated using the experimental data of the CONAN test facility. Finally, the applicability of the condensation modeling in the model containment THAI+ is tested.
