Abstract
In the framework of the JT-60SA project, a cryogenic loop, dedicated to the tests of the JT-60SA Toroidal Field Coils, is planned to be installed at CEA Saclay. To analyze the dynamic thermal behavior of the cryogenic loop and to optimize the cryogenic process control of the coil test facility, dynamic simulations will be carried out with the software EcosimPro. This paper deals with the validation of the software. Experimental power measurements in pure refrigeration on a helium refrigerator have been compared to computations. Results are close and allow validating the software. The modeling of the JT-60SA CTF cryogenic test loop is also described in order to give an overview of the next computations.
