“…N RECENT years the increasing importance gained by the superconducting magnet system in the frame of the ITER project, brought to the development of a large set of computational tools [1]- [6] with different degrees of complexity and various targets, to assist and verify the design of superconducting magnets as well to perform the analysis of experimental data during the preparatory R&D phase. The added value of the most advanced codes is their capability to simulate simultaneously different aspects of the operation of a superconducting coil but the cost to achieve it is typically an increased complexity in the problem definition [6] or the necessity to adapt very different codes to run within a standard software manager [7].…”

Abstract-A new integrated computer code is being developed for the simulations of the overall behavior of the ITER magnet cryo-system. The existing THEA, FLOWER and POWER codes, assembled as modules of a computational environment (SuperMagnet) have been upgraded to perform global simulations of the cooling circuit for the ITER magnet system. The thermal coupling resulting from the generic geometric configurations has been implemented to realize quasi-three-dimensional simulations of the winding pack. In this paper we present details on the model.

“…One of the main issues, from the point of view of the cryoplant design, is the pulsed nature of the (inductive) tokamak operation, which makes the design load of the cryoplant much higher than what is actually needed during most of the operation, leading to lower efficiency and higher costs. In order to smooth the heat load variation during the pulse, a saturated liquid helium (LHe) bath is used as a thermal buffer (see Figure 1), but, as this is still not enough, several active strategies to achieve this smoothing are being investigated [2,3,4].…”

Abstract. In superconducting tokamaks, cryoplants provide the helium needed to cool the superconducting magnet systems. The evaluation of the heat load from the magnets to the cryoplant is fundamental for the design of the latter and the assessment of suitable strategies to smooth the heat load pulses induced by the pulsed plasma scenarios is crucial for the operation. Here, a simplified thermal-hydraulic model of an ITER Toroidal Field (TF) magnet, based on Artificial Neural Networks (ANNs), is developed and inserted into a detailed model of the ITER TF winding and casing cooling circuits based on the state-of-the-art 4C code, which also includes active controls. The low computational effort requested by such a model allows performing a fast parametric study, to identify the best smoothing strategy during standard plasma operation. The ANNs are trained using 4C simulations, and the predictive capabilities of the simplified model are assessed against 4C simulations, both with and without active smoothing, in terms of accuracy and computational time.
