Description
The 1stst Specific Grant of the Framework Partnership Agreement 372 deals with experimental activities in support of the Conceptual Design of HCLL and HCPB Test Blanket Systems. Service-2 is focused on thermal-hydraulic tests with high pressure Helium for validation and benchmarking of suitable dedicated numerical tools. In this frame, an extensive experimental campaign has been executed in He-FUS3 (European helium cooled blanket integral test) facility designed and realized at ENEA Brasimone Research Center, to test the thermal-mechanical properties of prototypical module assemblies of the ITER and DEMO reactor. The actual facility has been upgraded with an elevated performances turbocirculator and an additional water cooling system that integrates the pre-existent Air Cooler. In addition, a dedicated Test Sections located in the loop hot zone has been settle down with the objective to investigate safety relevant transient conditions of an “In-TBM” LOCA event. Experiments have been conducted for a wide range of HCS relevant operating conditions, in order to investigate the whole facility T/H performances (cold and hot conditions) with special interest in the turbocirculator operating region assessment. Moreover, incidental tests representative of LOFA, “In-TBM”/“CVCS Area” LOCAs scenarios have been included. The main experimental outcomes, herein reported and discussed, have also provided a valuable data base for T/H system codes validation, thus allowing the implementation of a newly RELAP5-3D©© numerical model of the actual He-FUS3 layout. A post-test numerical analysis was performed in order to evaluate the model consistency and validate the code capability to adequately reproduce and predict the system behaviour. Code results have been compared with experimental data and the main issues related to the modelling capabilities have been addressed.
