SEEDS-2 experiments ready to start

A step forward was taken at the Department of Radiation Science and Technology of TU Delft, The Netherlands. The SEEDS experimental loop (SEven rods bundle Experiment in Delft for Sesame) was changed replacing the SEEDS-1 (inaugurated in November 2017) test section with the SEEDS-2 test section. SESAME colleagues from NRG visited the new setup.

The SEEDS-2 test section is a 7-rods hexagonal bundle facility with wire spacers wrapped around the rods to mimic the geometry of a liquid metal reactor core. The gravity-driven water flow is studied mainly by Particle Image Velocimetry.

The results will generate an experimental benchmark within the SESAME framework contributing to the validation and development of innovative numerical approaches for predicting the fluid dynamics in rod bundles of liquid metal reactors.
