Effect of Bulk Condensation on Containment Athmosphere Mixing SUMMARY The impact of bulk condensation on the mixing dynamics of gases and flammability of the containment atmosphere is investigated in detail using OpenFOAM-based ‘containmentFOAM’ CFD package developed at Forschungszentrum Julich. The bulk condensation is efficiently modeled by bringing the local gas Read more
A hybrid experimental and numerical investigation on the Cr2AlC-coated zirconium for accident-tolerant fuel systems SUMMARY This study utilized a hybrid experimental and numerical approach to investigate the failure behavior of zirconium substrates coated with Cr2AlC. The failure mechanism was determined through a series of interrupted in-situ three-point bending tests in Read more
Shielding Fuel Assembly Design Optimization SUMMARY The aging nuclear fleet is facing demand of lifetime extension to ensure reliable and carbon-free energy production. A major limiting parameter for lifetime extension is the neutron fluence of the reactor presure vessel. Furthermore, new requirments on flanges may require extensive material investigations.Framatome’s shielding Read more
Equipment Selection Methodology of Seismic Probability Safety Assessment for Nuclear Power Plant 1. Introduction A typical seismic probability safety assessment (SPSA) requires geological, structural, and systems analysts. In the case of probabilistic seismic hazard analysis (PSHA), geological experts can independently perform the analysis, but structural experts performing seismic fragility analysis Read more
Following the Fukushima nuclear disaster in 2011 and based on the lessons learned from the accident, there have been many changes to the relevant safety design criteria and/or regulations around the world. Read more…
Preliminary CFD analysis of innovative decay heat removal system for the European Sodium Fast Reactor Concept 1 Introduction Sodium-cooled Fast Reactors (SFRs) are among the most advanced concept of the Generation-IV reactor systems [1] with extensive design, construction, operation and decommissioning experience. Several experimental, prototype and power reactors have been Read more
