v7.22.135 HSNV135 — Model META_LEMA_ANI: pressurized tube and variable temperature

Summary:

This test constitutes a numerical validation of the META_LEMA_ANI mechanical behavior model with the effect of metallurgical transformations developed for the fuel rod cladding material, Zircaloy. It is a tube subjected to internal pressure, taking into account the background effect and at a uniform and variable temperature over time (therefore several phases in presence). This test case is identical to HSNV134 modeling A, except that here, a phase change occurs.

There is no analytical solution. The results are either compared to those obtained by the operator CALC_META, or tested in non-regression.
