In the framework of the Generation IV ALFRED (Advanced Lead Fast Reactor European Demonstrator) design, a dedicated Test Section (TS) named HERO (Heavy liquid mEtal pRessurized water cOoled tubes) has been implemented in the large LBE (Lead-Bismuth Eutectic) pool integral effect CIRCE (CIRColazione Eutettico) facility at CR ENEA Brasimone. HERO is a mock-up (1:1 in length) of the ALFRED Steam Generator (SG), consisting of seven double wall bayonet tubes arranged in triangular pitch inside a hexagonal shell, with an active length of ~6 m.

In the frame of heavy liquid metal (HLM) technology development, CIRCE pool facility at ENEA/Brasimone Research Center was updated by installing ICE (Integral Circulation Experiments) test section which simulates the thermal behavior of a primary system in a HLM cooled pool reactor. The experimental campaign led to the characterization of mixed convection and thermal stratification in a HLM pool in safety relevant conditions and to the distribution of experimental data for the validation of CFD and system codes.
