In the framework of the validation process of the coupled RELAP5-3D/ANSYS Fluent tool, the objective of this work is carrying out post-test analyses on the following cases:
1) forced circulation in hot conditions
2) natural circulation
3) loss of forced flow, starting from two different power levels
RELAP5-3D and ANSYS Fluent models of the E-SCAPE facility are already available and they have been coupled for the pre-test simulations. However, additional improvement and tuning of the Fluent model are necessary for the comparison analysis with the experimental data.
