چکیده
In this study, a multi-physics modeling method was developed to analyze nuclear fuel rod's thermo-mechanical behavior especially for high temperature anisotropic creep deformation during ballooning and burst occurring in Loss of Coolant Accident (LOCA). Based on transient heat transfer nonlinear mechanical analysis, the present work newly incorporated special characteristics which include gap transfer, burnup dependent material properties, with anisotropy. The proposed tested through various benchmark analyses showed good agreements analytical solutions. From validation study cladding experiment postulates LOCA scenario, it shown that development could predict behaviors accurately capability LOCA. Moreover, order verify methodology comparison between made isotropic assumption. It found more realistic cladding.

The Analysis of TRACE/FRAPTRAN in the Fuel Rods of Maanshan PWR for LBLOCA
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...
