Full textThe objective of this study is to investing ate the thermo-mechanical behaviour of a fuel rod which is composed of a tube containing cylindrical uranium dioxide fuel pellets. A lot of work has been particularly devoted to the design and the set up of an original experimental device which allows the simulation of the pellet-cladding mechanical interaction during the uprating of water pressurised reactors. The mode) is a two-dimensional plane stress one which has not taken the effects of irradiation and chemical transformation into account. Both experimental and numerical analyses on the cladding stresses concentration have been carried out. Different effects have been studied including the presence of cracks in the pellets, the coefficient of friction between pellet-cladding, the initial gap at the pellet-cladding interface, the cladding external pressure and the variation of power, The comparison of experimental and numerical results, for a particular case, enables a better understanding of pellet-cladding mechanical interaction et demonstrates that the modelisation of the joint element used in the pellet-cladding interface is appropriate. It should be pointed out that a simple elastic approach had been carried out before the thermoplastic experiment was done, aiming at analysing the stress concentrations due to the presence of cracks in the pellet

Full textZircaloy-4 is an alloy mainly composed of zirconium (~ 98%wt.) constituting the cladding of nuclear assemblies. Currently, used Zircaloy claddings are intended for deep geological storage due to their contamination by radioelements from the nuclear reaction and the reprocessing process. They are classified as long-lived intermediate-level waste according to ANDRA recommendations (radioactivity: 10 6 - 10 9 Bq/g, periods > 31 years), as they represent 25%wt. of the assembly inventory. Zirconium recycling thus could present an economic interest, either to upgrade the zirconium by remanufacturing sheaths (with the constraint imposed by the residual presence of 93Zr), or to downgrade the cladding wastes into low activity waste. This thesis aims to study the potential routes for the recycling of zirconium contained in spent Zircaloy sheaths, and more precisely electrorefining in molten fluorides. The study of Zircaloy sheath composition of spent nuclear fuel was first carried out to identify the radioelements present in used claddings. These elements are either activation products (Cr, Fe, Ni, Co, Sn, etc.), or fission products (H, Sr (+ Y), Cs (+ Ba), Eu, etc.), or actinides (U, Pu, Am and Cm). An electrochemical study of the zirconium (IV) ions was carried out in LiF-NaF at 750 °C to determine its reduction mechanisms into metallic zirconium. Then, a nucleation / growth study was performed to optimize the operating conditions (ie nature of the cathode, concentration of ZrF4, current density applied, etc.), to obtain an adherent metal zirconium deposit on inert solid cathode. The last part of this work was focused on the electrorefining of "fresh" Zircaloy sections, i.e. before its stay in the reactor. Particular attention was paid to the behavior of the alloy constituents (Fe, Cr and Sn), during the electrolysis process. This work proposes a first scenario for the reprocessing of spent fuel claddings

Full textOxide dispersion strengthened (ODS) steels are considered as candidate materials for thedevelopment of fuel cladding for sodium-cooled fast reactors (SFR). Resistance upset welding of thecladding is studied in this work. The aim is to determine and to understand the process effects on themicrostructure of ODS steels with 9% and 14% of chromium at the scales of the grains and thenanometric oxides. An approach coupling microstructural characterization of welds, numericalsimulation and physical simulation of the process, using a thermomechanical simulator Gleeble 3500,is proposed. Resistance welding locally imposes severe thermomechanical conditions in terms of strain,strain rate and temperature. Refinement of the microstructure is noted and correspond to a dynamicrecrystallization mechanism (14 % Cr steel) or the combination of dynamic recrystallization and phasetransformations (9 % Cr steel). The conditions of occurrence of dynamic recrystallization are studied.The possibility of a transition between continuous and discontinuous dynamic recrystallization is shownfor the 14 % Cr steel according to the loading conditions. Such severe thermomechanical conditionsinduce an increase in the size of nanoscale oxides associated with a decrease of their volume fraction

Full textFuel clads made of zirconium alloys are the first safety barrier in the nuclear power plants. This work aims to enhance the understanding of the thermomechanical behavior of Zirlcaoy-4 during RIA accidental scenario. Indeed, the current experimental databases are mainly constituted of uniaxial tensile tests carried out under isothermal conditions. The anisothermal character of the loading, coupled or not with the biaxiality of the mechanical loading, has been poorly studied. The aim of the thesis is to develop new experimental setups to highlight the effect of anisothermal loading. A first experimental test device was developed to study the effects of temperature transient on the cladding material during uniaxial tensile test. The experimental setup allows to reproduce loading conditions close to the ones occuring during a RIA accident. It allows clad testing up to 600 °C.s-1 heating rates coupled to rapid mechanical loading reaching 5 s-1 in terms of strain rate. First experiments showed first effects of anisothermal loading and allowed us to establish as a second step a comparison between isothermal and anisothermal states. A marked effect of anisothermal loading was observed at low strain rates and high heating rates : the flow stress is much higher than that expected from the isothermal tests. A study of the recrystallization of the material under dynamic conditions has shown that a delay in triggering the recrystallization process would be the cause of the anisothermal e ects observed during the tensile tests. A second experimental device was developed to couple effects of biaxial and anisothermal loading. A sheet of Zircaloy-4 was tested along its two main directions (rolling and transverse) with an induction heating system. Several heating rates and biaxiality ratios were explored and failure strains were determined for each experimental condition. The analysis of the tests showed that the multiaxiality of the loading is the dominant parameter with regard to the ductility of the material, no significant influence of the anisothermal loading was observed during these tests. In support of the analysis of uniaxial and biaxial anisothermal tensile tests, numerical FEM calculations were undertaken using a macroscopic mechanical behavior model developed in this study. These simulations made it possible to determine the stress fields of the biaxial tests and showed that the tests carried out were in the field of interest of the RIA studies
