It is the 2nd Meeting of the Programme Review Group and Management Board of the OECD/NEA ATLAS Phase 2 Project, ATLAS stands for Advanced Thermal-hydraulic Test Loop for Accident Simulation (ATLAS) Project. The project is led by The Nuclear Energy Agency framework of the Organisation for Economic Co-operation and Development .The ATLAS project is aimed at topics of high safety relevance for both existing and future nuclear power plants. The main objective of the NEA ATLAS Project is to provide experimental data for resolving key LWR thermal-hydraulics safety issues related to multiple high-risk failures and highlighted in particular from the Fukushima Daiichi nuclear power plant accident, by using the ATLAS facility at KAERI.
