abstract = {The severe reactor accident at Fukushima Daiichi Nuclear
Power Plant (2011) has confirmed the need to understand the
flow and transport processes of steam and combustible gases
inside the containment and connected buildings. Over several
years, Computational Fluid Dynamics (CFD) models, mostly
based on proprietary solvers, have been developed to provide
highly resolved insights; supporting the assessment of
effectiveness of safety measures and possible combustion
loads challenging the containment integrity. This paper
summarizes the design and implementation of containmentFOAM,
a tailored solver and model library based on OpenFOAM®. It
is developed in support of Research $\&$ Development related
to containment flows, mixing processes, pressurization, and
assessment of passive safety systems. Based on preliminary
separate-effect verification and validation results, an
application oriented integral validation case is presented
on the basis of an experiment on gas mixing and H2
mitigation by means of passive auto-catalytic recombiners in
the THAI facility (Becker Technologies, Eschborn, Germany).
The simulation results compare well with the experimental
data and demonstrate the general applicability of
containmentFOAM for technical scale analysis. Concluding the
paper, the strategy for dissemination of the code and
measures implemented to minimize potential user errors are
outlined},
