This paper presents the results of Power To Melt and Maneuverability (P2M) Simulation Exercise on past fuel melting irradiation experiments, organized within Organisation for Economic Co-operation Development/Nuclear Energy Agency Framework IrraDiation ExperimentS (FIDES) framework by Core Group (CEA, EDF, SCK‧CEN) open to all FIDES members. The exercise consisted in simulating two power ramps where was detected: (1) xM3 staircase transient [ramp terminal level (RTL) 70 kW‧m−1, average...
This work focuses on the effects of inclusion proximity elastic behavior dilute matrix-inclusion composites. Rigid or soft monodisperse spherical inclusions are considered with moderate volume fractions. To conduct this study, Representative Volume Elements (RVE) an effective local minimum distance between varying sphere’s radius and one-tenth built. Numerical finite element calculations RVE performed. The obtained homogenized properties, as well phase stress moments (first second), compared...
The experimental Electron Probe Micro Analysis (EPMA) characterizations on the MOX fuels evidence a heterogeneous microstructure, containing several phases. This heterogeneity must be accounted for in numerical simulation. first phase of this work, presented here, concerns exclusively representation microstructure three dimensions. Three identified steps were realized. one consisted acquisition and treatment two-dimensional pictures thanks to soft-ware already developed [1]. From made...
La répartition hétérogène du plutonium dans le combustible nucléaire MOX implique que la modélisation de son comportement, durant l’irradiation en réacteur à eau pressurisée, passe par construction lois macroscopiques faisant intervenir les effets microstructuraux. Pour homogénéiser ce problème local, nous avons choisi une méthode d’analyse champs transformation non uniformes, abrégé anglais NTFA (J.-C. Michel, P. Suquet, Int. J. Solids Struct. 40 (2003) 6937–6955). Nous présentons donc ici,...
AbstractCYRANO3 is the thermal-mechanical industrial code developed and used by Electricité de France (EDF) to simulate nuclear fuel rod performance under normal transient conditions (power ramp tests) in pressurized water reactors during transport storage periods, as well. This has already been successfully EDF for last 30 years justify operations category 2 transients, covering various types of fuels: UO2, UO2 + gadolinium, mixed oxide, claddings, well those proposed suppliers: Zircaloy-4,...
