Database of available existing wire spaced rod bundle experiments

This report provides a literature review with respect to thermal-hydraulic experiments on rod bundles with wire spacers, representative of fuel assemblies in liquid-metal cooled fast reactors.  Both isothermal and heated tests are evaluated, for nominal and non-nominal geometries.

General acceptance criteria are defined for incorporating experiments into this review. The most relevant one is the related to the geometry: only the classical case with one wire per pin is considered. Further additional acceptance criteria are defined for each scenario. All rejected cases are listed in the appendix.

Only publicly available data are considered, with a cut-off date of December 31st, 2023. Ongoing activities are also mentioned, mostly from European collaborative projects, since results are expected to be published soon. A discussion on the comparison with simulation results is presented.
