This report reports the results of an experimental campaign performed in the HE-FUS 3 facility in order to provide a reliable experimental data base far the assessment of thermal-hydraulic codes used far High Temperature Reactor (HTR) and Very High Temperature Reactor (VHTR) design and safety analysis. Moreover, the campaign was also addressed to a complete characterization of the helium loop. In particular, the plant start-up by steps was carried aut in order to collect data at different steady state conditions far the characterization of the heat Iosses and compressor performances. A set of transients representative of operational and accident conditions that are of particular meaning far the assessment of T/H cades were performed in order to obtain relevant experimental data. These tests consisted of two Loss of Flow Accidents with a different dynamic of the accidental event and two Loss of Coolant Accidents at different loop pressure.

Abstract
This report reports the results of an experimental campaign performed in the HE-FUS 3 facility in order to provide a reliable experimental data base far the assessment of thermal-hydraulic codes used far High Temperature Reactor (HTR) and Very High Temperature Reactor (VHTR) design and safety analysis. Moreover, the campaign was also addressed to a complete characterization of the helium loop. In particular, the plant start-up by steps was carried aut in order to collect data at different steady state conditions far the characterization of the heat Iosses and compressor performances. A set of transients representative of operational and accident conditions that are of particular meaning far the assessment of T/H cades were performed in order to obtain relevant experimental data. These tests consisted of two Loss of Flow Accidents with a different dynamic of the accidental event and two Loss of Coolant Accidents at different loop pressure. In this technical report the 7-pin Test Section, specifically assembled far this test campaign, the circuit, modified to host the Test Section, and the achieved results are described.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
