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 t...

In this work, a brand new passive safety injection system has been designed for the ocean-based Qinshan Phase I nuclear power plant to update and replace traditional active ones. The is made up of high pressure, medium lower pressure system, two-stage automatic depressurization system. To evaluate performance, double-ended cold leg large break LOCA analyzed by best-estimated analysis RELAP5 cod...

In the frame of activities promoted and encouraged by EUROfusion Consortium aimed at developing EU-DEMO fusion reactor, great emphasis has been placed a very early stage design to incorporate provisions needed improve overall plant safety reliability performances as well analyse possible mitigation actions. this framework, research activity focused on representative relevant cooling loop Helium...
