چکیده

Modeling fuel behavior requires an accurate description of the cladding stress response for both operational and safety considerations. The transient creep response of Zirconium alloys is commonly modeled using a strain hardening rule which is known to hold in cases with monotonously increasing stresses. However, the strain hardening rule is experimentally known to fail in scenarios such as load drop or

Modelling of Zircaloy cladding primary creep during load drop and reversal

Modelling fuel behaviour requires an accurate description of the cladding stress response for both operational and safety considerations. The transient creep response of Zirconium alloys is commonly modelled using a strain hardening rule which is known to hold in cases with monotonously increasing stresses. However, the strain hardening rule is experimentally known to fail in scenarios such as ...

Thermophysical and Mechanical Analyses of UO2-36.4vol % BeO Fuel Pellets with Zircaloy, SiC, and FeCrAl Claddings

The thermophysical performance and solid mechanics behavior of UO2-36.4vol % BeO fuel pellets cladded with Zircaloy, SiC, and FeCrAl, and Zircaloy cladding materials coated with SiC and FeCrAl, are investigated based on simulation results obtained by the CAMPUS code. In addition, the effect of coating thickness (0.5, 1 and 1.5 mm) on fuel performance and mechanical interaction is discussed. The...

Comparison of Silicon Carbide and Zircaloy4 Cladding during LBLOCA

The pressure and temperature histories on cladding inner and outer surfaces during of LBLOCA (Large Break Loss of Coolant Accident) are considered as boundary conditions for the structural analyses of three cladding materials. Since SiC (Silicon Carbide) has higher yield and ultimate strengths than Zry-4 (Zircaloy-4) under the same primary stresses, SiC has higher primary safety margin than Zry...

WAPD-T-3173, " The Corrosion of Zircaloy-Clad Fuel Assemblies in a Geologic Repository Environment."

Recently analyzed long-term Zircaloy autoclave corrosion data were used to develop new Zircaloy corrosion correlations. Calculations were performed to estimate the additional quantity of corrosion that may be experienced by spent Zircaloy-c1ad fuel assemblies from long-term exposure to geologic repository conditions. These estimates indicate that the level of general corrosion is very small and...

Comparison of Pellet-Cladding Mechanical Interaction for Zircaloy and Silicon Carbide Clad Fuel Rods in Pressurized Water Reactors

Contact between the outer surface of a fuel pellet and the inner surface of the fuel rod cladding can result in several kinds of undesirable behavior. As the pellet swells outward and the cladding creeps down, large stresses are generated in both the pellet and the cladding. This contact may exacerbate chemical degradation of the cladding and the stress may enable rapid propagation of cracks. B...
