Abstract
Work is described that has been done to modernise the mechanical modelling of FRAPCON and FRAPTRAN codes. FRAPCON and FRAPTRAN are nuclear fuel performance codes for steady-state and transient analyses, respectively. A new stress and strain analysis approach with a finite element model has been implemented in the codes. The finite element model is capable of handling material nonlinearities such as elastic, thermal, plastic and creep deformations, and geometric nonlinearities like large localised cladding deformations, e.g. ballooning of the cladding under loss-of-coolant accident conditions.
