3. Modeling A

3.1. Behavioral law and material parameters

The law of behavior tested “GRAN_IRRA_LOG”, is documented in doc R5.03.09. It is a law of creep and enlargement behavior under irradiation for fuel assemblies, similar to the law “VISC_IRRA_LOG” for viscoplastic deformation, which also includes a deformation of enlargement under irradiation.

Values of the parameters used:
