Cladding creep

Webcladding ballooning and burst model were developed and implemented into FRAPTRAN2.0P1. Instead of BALON2 model, creep model is applied and instability method is not used. Burst strain criteria is also updated. As validation result, prediction of cladding behavior by new creep model is improved in terms of hoop strain and burst time. WebThermal Creep – Fuel Cladding • Thermal creep is a time dependent deformation under an applied load – For fuel rods this is normally associated with an increase in fuel rod length primarily as a result of the internal rod pressure (RIP) – Generally only occurs at high temperature • Insignificant creep at pool storage temperatures
