Design and construction of the sodium thermal-hydraulic experimental facility: Stella-1

A large-scale sodium thermal-hydraulic test program called STELLA (Sodium Test Loop for Safety Simulation and Assessment) and its first test facility aiming at a performance demonstration of the major components and the V and V of their design were briefly introduced with the preliminary CFD analysis results for assessing the thermal-hydraulic performance of the major heat exchangers, e. g. DHX (sodium-to-sodium decay heat exchanger) and AHX (sodium-to-air heat exchanger. High temperature design and analysis of each test heat exchanger have been carried out, and the features of creep-fatigue damage at critical parts of each test heat exchanger unit are also evaluated and discussed according to the high temperature design codes, e. g., ASME-NH and RCC-MR
