Best-Estimate for System Codes (BeSYC): A New Software to Perform Best-Estimate Plus Uncertainty Analyses with Thermal-Hydraulic and Safety System Codes for Both Fusion and Fission Scenarios

The development and the validation of old new software in relevant DEMO reactor conditions have been exploited latest years within EUROfusion Consortium. aim was to use—if possible—the already validated for fission reactors fill gaps with ad-hoc software. As contribution this effort, Karlsruhe Institute Technology (KIT) developed tested a novel apply Best-Estimate Model Calibration Prediction through Experimental Data Assimilation methodology system codes RELAP5-3D, MELCOR 1.8.6, 2.2. This is called Best-estimate SYstem Codes (BeSYC), it as MATLAB App. application charge applying mathematical framework methodology, writing executing code runs required by printing obtained results. main goal BeSYC wrap up suitable be used any user simple graphical interface. Albeit fusion research context, can applied reactor/scenario type supported specific code. goals BeSYC, framework, characteristics, performed verification activities are described paper.
