dc.description.abstractThis study examines modeling uncertainty in slug flow due to the use of a uniform density in neutronic simulations. We created a detailed neutronic model of the slug flow regime, in the form of a Taylor bubble and small bubbles, in a periodic slug unit height. We explored various slug flow representations in a square unit cell geometry of a boiling water reactor and deviations (delta k) in k(infinity) from the uniform approach. We used OPENMC with the ENDF/B-VIII.0 library for neutronic simulations. The results showed that depending on how much the slug flow is detailed, uncertainty in modeling can be as high as 7300 pcm and strongly varies with the overall void fraction, Taylor bubble void fraction, and slug unit height but not with small bubbles size. With the inclusion of the Taylor bubble and small bubbles, the maximum uncertainty is calculated to be about 700 pcm. (C) 2022 Elsevier Ltd. All rights reserved.
