CFD evaluation of hydrogen risk mitigation measures in a VVER-440/213 containment
TLDR
The purpose of this work is to demonstrate that CFD codes can be used to model gas movement inside a containment during a severe accident, and to encourage the use of CFD in assessing the risk of losing containment integrity as a result of hydrogen deflagrations.About:

A review on hydrogen generation, explosion, and mitigation during severe accidents in light water nuclear reactors
TL;DR: In this paper, the authors provided a review of what has been done in the literature with regard to hydrogen generation in severe accidents of nuclear power plants and identified the literature gaps and underlined the need of developing a systematic hydrogen management strategy.

Simulation of hydrogen distribution in an Indian Nuclear Reactor Containment
TL;DR: In this article, the authors present the results of systematic work carried out using the commercial Computational Fluid Dynamics (CFD) software FLUENT to assess the concentration distribution of hydrogen in a typical Indian Nuclear Reactor Containment.
Journal ArticleDOI
Simulation of gas mixing and transport in a multi-compartment geometry using the GOTHIC containment code and relatively coarse meshes
TL;DR: The results obtained for these experimental data using the advanced containment code GOTHIC and relatively coarse meshes, which are coarser than the ones typically used for the simulation with commercial CFD codes, but are still representative of the models which are currently affordable for a full containment analysis.

Three-dimensional all-speed CFD code for safety analysis of nuclear reactor containment: Status of GASFLOW parallelization, model development, validation and application
TL;DR: GASFLOW as mentioned in this paper is a three dimensional semi-implicit all-speed CFD code which can be used to predict fluid dynamics, chemical kinetics, heat and mass transfer, aerosol transportation and other related phenomena involved in postulated accidents in nuclear reactor containments.
Dissertation
Development, use, and validation of the CFD tool FLACS for hydrogen safety studies
TL;DR: In this article, a 3-step approach is proposed, in which the CFD-tool FLACS is used to estimate the risk of hydrogen explosion using a utility program.

TL;DR: GASFLOW as mentioned in this paper is a 3D fluid dynamics field code to characterize local phenomena within a flow field, such as circulation patterns, flow stratification, hydrogen distribution mixing and stratification; combustion and flame propagation; effects of noncondensable gas distribution on local condensation and evaporation; and aerosol entrainment, transport, and deposition.

Fluid dynamic analysis of a catalytic recombiner to remove hydrogen
TL;DR: In this paper, the authors describe the use of the CFX (CFX 4.1 Flow Solver User Guide) for creating a recombiner model and its comparison with existing test data is discussed.
