Results of the Pretest Analysis and Start-up of the JRC-Ispra Pressurized Thermal Shock Experiment: Nozzle Corner Crack Behaviour

THE PAPER SHOWS THE GENERAL AND PRACTICAL ASPECTS OF THE ANALYTICAL AND EXPERIMENTAL WORK PERFORMED WITHIN THE JRC ISPRA PTS (PRESSURIZED THERMAL SHOCK) RESEARCH. MAIN ELEMENTS OF THE STRUCTURAL RELIABILITY ASSESSMENT PERFORMED FOR THE SCALED PRESSURE VESSEL MODEL EXPOSED TO REPETITIVE PTS LOADS HAVE BEEN HIGHLIGHTED AND FIRST RESULTS REGARDING THE PRE-EXPERIMENT ANALYSIS AND THE START-UP PHASE OF THE EXPERIMENT GIVEN (STRESS ANALYSIS, DAMAGE MECHANICS, FRACTURE MECHANICS, ETC.). THE PAPER PRESENTS ALSO THE BASIC IDEA AND FIRST APPLICATIONS REGARDING THE TREATMENT OF UNCERTAINTIES AND USE OF THE ARTIFICIAL INTELLIGENCE TOOLS IN PLANNING AND MANAGEMENT OF THE EXPERIMENT.
