Protected loss of flow accident simulation in circe-hero facility: experimental test and system code assessment
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.
