During hypothetical loss-of-coolant accidents (LOCA), zirconium-based nuclear fuel claddings can be exposed to high temperatures in the βZr phase domain and absorb substantial amounts of hydrogen (up about 3000 weight ppm) oxygen 1 %). This paper provides novel data combined effects contents on mechanical behavior (prior-)βZr phase, as a function temperature, upon cooling from temperature range...

Fuel rod analysis program transient (FRAPTRAN) code was used to study the fuel rod performance during a postulated large break loss of coolant accident (LBLOCA) in Maanshan nuclear power plant (NPP). Previous transient results from thermal hydraulic code, TRACE, with the same LBLOCA scenario, were used as input boundary conditions for FRAPTRAN. The simulation results showed that the peak claddi...

This paper describes a multi-scale modeling approach to compute the large-strain deformation of zirconium alloy cladding, which is of interest to the study of fuel rod behaviors in transient and accident conditions. A Visco-Plastic Self-Consistent (VPSC) polycrystal plasticity model representing polycrystals by weighted orientations of single crystals has been implemented as the constitutive la...
