Modeling of Zircaloy cladding primary creep during load drop and reversal
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 loa...

متن کاملA Mechanism-Based Framework for the Numerical Analysis of Creep in Zircaloy-4
A deformation-mechanism map has been developed for unirradiated zircaloy-4 based on the creep data available from the literature of the last thirty-five years. These data have been analyzed to identify different creep mechanisms, based on the forms of the relationships between stress, temperature and strain rate. This identification allowed the activation energies and other associated creep par...
متن کاملSteady State Analysis of Nanofuel Droplet Evaporation
The potential for nanofuels as one of the clean sources of energy on account of its enhanced combustion performance coupled with low emissions has been established. Considering the importance of the fuel evaporation phase in the entire combustion process, this work presents an attempt at applying the steady state analysis equations to nanofuel experimental data obtained from the li...
متن کاملDevelopment of a used fuel cladding damage model incorporating circumferential and radial hydride responses
At the completion of the fuel drying process, used fuel Zry4 cladding typically exhibits a significant population of d-hydride inclusions. These inclusions are in the form of small platelets that are generally oriented both circumferentially and radially within the cladding material. There is concern that radiallyoriented hydride inclusions may weaken the cladding material and lead to issues du...
