The PYRAMID project is an International Collaborative Research Project (PRCI), which brings together French public laboratories (MATEIS and LVA at INSA Lyon, and CEA), an International Joint Unit (ELyTMaX), Japanese public laboratories (IFS, and GSE at Tohoku University, GSST at Gunma University), and the Nuclear Technology Research Laboratory at CRIEPI a non profit researchfoundation, supported by the electrical japanese industries. PYRAMID project aims to develop new tools and techniques to detect and quantify wall thinning due to Slurry Flow induced Corrosion (SFC) in piping systems. SFC is a special case of Flow Accelerated Corrosion (FAC) in presence of a flow with a high concentration of debris of various kinds(concrete, corrosion, metallic…). The final goal is to provide a risk management system based on prediction-monitoring of wall thinning due to SFC.
