14 REACTIVITY Compactness ITER Challenge : Largest cryogenic system in the world Compactness = cost reduction Development of fins with high efficiency Very high density : 28 FPI (Fins per inch) Pitch p(mm)=0.91 mm Heat transfer surface : > 2000 m2/m3 14 CRYOGENICS Isabelle NAUDE

15 RELIABILITY Expertise on flow distribution ITER Challenge : He with very tight temperature pinch Uneven flow distribution = deterioration of thermal performance Specific design rules to have homogeneous flow distribution Repartition of pressure drop Exchanger configuration Per layer (between right and left path) Inter layers 15 CRYOGENICS Isabelle NAUDE

16 RELIABILITY / PERFORMANCES PROSEC Simulation software : static and dynamic ITER Challenge : Flexibility and stability over a wide range of operating modes PROSEC PROSEC 3D Validated by measurements on site PROSEC Dynamic 16 CRYOGENICS Isabelle NAUDE Check performances for different cases (design, upset, ) Analyse of transient conditions (start-up, changes of operating mode, failure conditions ) Better understanding of the thermal core behaviour and mechanical impact
