IAEA Programme to Support Development and Validation of Advanced Design and Safety Analysis Codes

Abstract

The International Atomic Energy Agency (IAEA) has been organized many international collaboration programs to support the development and validation of design and safety analysis computer codes. These programs are normally implemented with a frame of Coordinated Research Project (CRP) or International Collaborative Standard Problem (ICSP). This paper introduces CRPs and ICSPs currently being organized and recently completed by IAEA for this purpose. That includes three CRPs (Natural Circulation Phenomena, Modelling, and Reliability of Passive Systems that Utilize Natural Circulation; Benchmarking Severe Accident Computer Codes for HWR Applications; Prediction of Axial and Radial Creep in Pressure Tubes) and four ICSPs (Comparison of HWR Thermalhydraulic Code Predictions with SBLOCA Experimental Data; Integral PWR Design Natural Circulation Flow Stability and Thermo-hydraulic Coupling of Containment and Primary System during Accidents; HWR Moderator Subcooling Requirements to Demonstrate Backup Heat Sink Capabilities of Moderator during Accidents; Prediction of Hydro-Mechanical Behaviour in Reactor Core with Plate-Type Fuel Assembly).
