A different S/C pool module, called POOL-3D, has been introduced in the SAMPSON code and the pool has been modeled using a multi-node finite volume approach. The S/C has been discretized using a detailed mesh in order to capture the thermal stratification generated by the steam injection and reproduce the PCV pressure transient. In this work, the first 70 hours after the earthquake were simulated focusing on the S/C pool thermal-hydraulics parameters. The calculated results can help to understand how the S/C pool conditions affect the PCV.
