Marco Frosolini | Sviluppo ed implementazione di tecniche di Lean Manufacturing per l'efficientamento della produzione in contesti produttivi X-To-Order | Sviluppo di tecniche e modelli Lean a supporto delle varie Operations Aziendali | L'obiettivo è studiare l’evoluzione dei principi di Lean Manufacturing ed il loro adattamento agli ambienti di produzione X-To-Order (XTO). Il tutto, quando possibile, tenendo conto dei dettami moderni sull’automazione e la digitalizzazione di fabbrica meglio noti con l’accezione Industria 4.0. L’obiettivo è sviluppare tecniche e modelli a supporto delle varie Operations aziendali. In particolare, lo studio effettuato nel primo anno di Dottorato ha riguardato quattro differenti aree: Manutenzione, Sicurezza, Logistica e Produzione. | https://docs.google.com/a/dici.unipi.it/viewer?a=v&pid=sites&srcid=ZGljaS51bmlwaS5pdHxwb3N0ZXJ8Z3g6NjU4MDQwZjA3YWQzMjkyNw |
| Ingegneria Nucleare | I | MARINARI Ranieri | DICI | Prof. Nicola Forgione, Dott. Ing. Daniele Martelli, Dott. Ing. Ivan Di Piazza (ENEA) | Numerical and experimental study of flow-blockage phenomena in HLM reactors | CFD simulations and experimental investigation of flow blockage in ALFRED FA | The main object of the present PhD research project is the experimental and numerical analysis (mainly with CFD codes) of the flow blockage phenomena in a HLM cooled bundle; in particular, its thermal-hydraulic effects on the coolant and on the pins near the blocked sub-channels and on the whole FA. Numerical simulations have a key role in the thermo-fluid dynamic analysis of these reactors due to the limited knowledge and data availability for these coolants. An appropriate test section was designed, procured and will be installed in the HLM NACIE-UP facility at the ENEA Brasimone R.C for the experimental investigation of flow-blockage phenomena in a pin bundle. Experiments will provide a unique set of data for validation of numerical approaches and turbulence models. The PhD activity is developed in collaboration with ENEA Brasimone R.C., in particular, the experimental activity require long term missions at ENEA. This activity is framed into the SESAME international project, in particular the Work Package 2 for the core thermal-hydraulic study where both ENEA and DICI are partners. | https://docs.google.com/a/dici.unipi.it/viewer?a=v&pid=sites&srcid=ZGljaS51bmlwaS5pdHxwb3N0ZXJ8Z3g6MjQzZGY4NjUyM2UzYTAxZA |
| Ingegneria Nucleare | II | VENTURINI Alessandro | DICI | Prof. Nicola Forgione, Dott. Ing. Daniele Martelli, Dott. Ing. Marco Utili (ENEA, C.R. Brasimone) | Pressure wave propagation in Lead-Lithium Eutectic | Experimental characterization of the pressure wave propagation in the liquid alloy | The experimental facility THALLIUM (Test HAmmer in Lead LithIUM) was designed, manufactured and installed at ENEA C.R. Brasimone to reproduce the geometry of the LLE (Lithium Lead Eutectic) loop of the HCLL TBM (Helium Cooled Lithium Lead Test Blanket Module). An experimental campaign was carried out in ITER relevant conditions. The experiments simulated a pipe rupture in a cooling plate of the HCLL TBM, injecting He at 400°C from a dedicated injection valve connected to He-FUS3 loop. The aim of the campaign was to study the release of high pressure He in the LLE due to In- box LOCA. Particularly, the fundamental phenomena to be observed are the pressure wave trend in the two pipes reproducing the pipe forest of the HCLL TBM in ITER and the effectiveness of the mitigation strategy designed for HCLL TBS in case of In-box LOCA. The main parameters that were varied during the experiments are: the injection time, the He pressure, the actuation of the isolation valves and the opening pressure of the rupture disk. In the pipe forest mock-up, the pressure wave showed three distinct peaks, related to the water hammer, to the LLE oscillations in the expansion tank and to He which finally fills the loop. The isolation valves proved to have a deep influence on the pressure wave propagation also when they do not close, being able to damp the peaks related to the first pressure wave. | https://docs.google.com/a/dici.unipi.it/viewer?a=v&pid=sites&srcid=ZGljaS51bmlwaS5pdHxwb3N0ZXJ8Z3g6NTBlODRhYWFmYTFlMzg4Mg |
