13. Modeling and simulation of cryogenic processes using EcosimPro

Dr Benjamin Bradu (CERN, EN department)

Differential and Algebraic Equations (DAE) are especially adapted to model and simulate thermo-hydraulic systems. CERN has developed a dedicated library to model helium cryogenic plants handling usual cryogenic components using DAE with a commercial software called EcosimPro. The aim of such a library is to provide a simple way to model large-scale cryogenic systems and perform dynamic...

23. Validation of the cryogenic circuit module in the 4C code against SHe closed loop data

Roberto Zanino (Politecnico di Torino)

The Cryogenic Circuit Conductor and Coil (4C) code has been recently developed for the simulation of thermal-hydraulic transients in the ITER magnets and cryogenic circuit [1]. The code validation was started against different types of transients ranging from (fast) safety discharge [2] to (slow) cool-down [3], but it did not include, so far, the cryogenic circuit module. Very recently, the...

19. THELMA Analyses of ITER NbTi Cable-in-Conduit Conductors

Prof. Fabrizio Bellina (Udine University, Dipartimento di Ingegneria Ingegneria Elettrica, Gestionale e Meccanica)

The THELMA code, developed for the analysis of coupled electromagnetic and thermal-hydraulic transients in superconducting Cable-in-Conduit Conductors (CICC) [1, 2], has been recently applied to the analysis of one of the two legs of the Poloidal Field Conductor Insert Full Size Joint Sample (PFCI-FSJS), a NbTi CICC short sample tested in the SULTAN facility. THELMA was able to reproduce the...

Oral

Cryogenic systems for future large superconducting tokamaks (e.g. JT-60SA or ITER) are expected to cope with large pulsed heat loads due to cycling plasma operation. Their superconducting magnets are cooled down with forced flow supercritical helium. An experimental set up named HELIOS [1] has been designed and realized in CEA Grenoble to study pulsed load effects on a forced flow...

43. Simulation of the Operation of the ITER Coils using a Domain

Luca Bottura (CERN)

Oral

The ITER magnet system has unprecedented complexity and stored energy, and its reliable operation will depend critically on the knowledge of the operating margins, and the optimal use of the large installed cooling capacity. We have tailored the system codes "glued" within the Supermagnet suite to perform simulations of the flow, temperature and operating margin during a sequence of plasma...

24. 4C analysis of thermal-hydraulic transients in the KSTAR superconducting magnet system

Laura Savoldi Richard (politecnico di torino)

The KSTAR tokamak [1] is operating since 2008 at the National Fusion Research Institute in Korea. KSTAR is equipped with a full superconducting magnet system including the central solenoid (CS), which is made of 4 symmetric pairs of coils PF1L/U-…-PF4L/U, the poloidal field coils PF5L/U-…-PF7L/U and the toroidal field coils TF1-...-TF16. The CS coils, the PF5 coils and the TF coils are pancake...
