Usine cryogénique
L'installation cryogénique comprend 5 400 m² de bâtiments ainsi que des aménagements extérieurs pour le stockage d'hélium et d'azote.
À l'image du plus gros tokamak jamais construit, l'usine cryogénique qui produit les fluides nécessaires au refroidissement des aimants supraconducteurs, des écrans thermiques et des cryopompes sera elle aussi hors norme, d'une taille et d'une puissance largement plus importantes que celles requises pour les tokamaks supraconducteurs existants.
Non loin du Complexe tokamak, sur une zone de 8 000 m², l'installation dédiée à la cryogénie comprend 5 400 m² de bâtiments ainsi que des aménagements extérieurs pour le stockage d'hélium et d'azote (liquide et gazeux).
Dans le Bâtiment « boîtes froides », trois unités de réfrigération fourniront l'hélium liquide (LHe) aux principaux utilisateurs de fluides froids—les 10 000 tonnes d'aimants supraconducteurs ainsi que les cryopompes qui créeront le vide très poussé dans le cryostat (volume de 8 500 m³) et la chambre à vide (volume de 1 400 m³). L'usine hélium dispose d'une capacité globale de réfrigération de 75 kW à 4,5 K (soit moins 269 °C), ce qui équivaut à un taux de liquéfaction maximum de 12 300 litres/h.
L'usine cryogénique produira également l'azote liquide (LN₂) utilisé dans les processus de « pré-refroidissement » au sein de l'unité de production d'hélium liquide ainsi que pour l'écran thermique. Les compresseurs d'azote seront installés dans le Bâtiment « compresseur » à côté des 18 compresseurs nécessaires au fonctionnement de l'unité hélium ; quant aux boîtes froides des usines azote, elles seront installées à l'extérieur du bâtiment. L'azote sera produit directement à partir de l'air ambiant par une usine de production d'azote gaz d'une capacité de 50 tonnes par jour, puis traité par les unités de réfrigération azote d'une puissance de refroidissement de 1 300 kW à 80 K.
Un système de récupération de chaleur sera installé dans le Bâtiment compresseurs pour récupérer les quelque 12 MW de chaleur générée par le fonctionnement des machines et les évacuer par un système de refroidissement. Cette énergie thermique sera utilisée pour chauffer les bâtiments de l'installation ITER.
Les fluides de refroidissement issus de l'usine de cryogénie seront acheminés par des lignes isolées sous vide installées à 13 mètres du sol sur un « pont » reliant le Bâtiment tokamak à l'usine. Environ cinq kilomètres de lignes cryogéniques permettront de fournir l'hélium (liquide et gazeux) aux systèmes situés à l'intérieur du Bâtiment tokamak. Les aimants supraconducteurs consommeront 45% de la puissance cryogénique ; l'écran thermique 40% et les cryopompes 15%. Quelque 25 tonnes d'hélium liquide à moins 269 °C circuleront dans l'installation ITER en période d'expériences scientifiques.
L'usine cryogénique ITER a été conçue pour s'adapter aux différents régimes de fonctionnement du tokamak—depuis les plasmas courts (quelques centaines de secondes) à 700 MW de puissance de fusion jusqu'aux plasmas longs (3 000 secondes) à 365 MW de puissance de fusion. Un ensemble de dispositifs garantit la fiabilité et la disponibilité des fluides en dépit des importantes charges thermiques et neutroniques auxquelles le système de distribution est soumis.
La réalisation de l'usine cryogénique et de son infrastructure est répartie entre ITER Organization (l'unité hélium) ; l'agence domestique européenne (l'unité azote et les systèmes annexes de même que les bâtiments sur la plateforme ITER) ; et l'agence domestique indienne (lignes cryogéniques et cryodistribution). Tous les équipements sont maintenant installés et les activités de mise en service sont en cours.

Two important roles
2020-11-12 - The cryogenic termination cold box has two roles: collecting and distributing cryogenic fluids produced in the cryoplant to the Tokamak Building, and warming up the fluids when it's time to bring clients back to room temperature for maintenance. Pictured: David Grillot, the head of ITER Cryogenic System Section.

One of the last giants
2020-06-02 - One of the last large components enters the ITER cryoplant: a 56-tonne helium dryer.
As dry as 'He' can get
2020-05-27 - Cold boxes do not like water. Before it is processed, gaseous helium needs to be perfectly dry to prevent damage. This crucial operation is the task of a 56-tonne ''helium dryer'' that was installed in the cryoplant on 27 May.
The octopus
2019-09-23 - Evocative of a monster bug or a creature from the depths, this multistage centrifugal compressor pressurizes nitrogen before liquefying it. Liquid nitrogen at 77 K (minus 196 °C) contributes to the cooling process of helium.
Compressor row
2019-09-23 - A total of 18 helium compressors and associated inlet filters and electrical motors are aligned on two parallel platforms inside the cryoplant.
Seven kilometres of pipes
2019-09-23 - Approximately seven kilometres of pipes run through the installation, carrying helium, nitrogen and cooling water for the compressors and other equipment. Cooling water circulation in the cryoplant is in the range of 2,500 cubic metres per hour—the equivalent of an Olympic pool every 30 minutes.
Three cold boxes plus one
2019-09-23 - Serving the ITER cold clients requires three "cold boxes" plus a fourth to connect them (the "termination cold box," to the left). The 21-metre components —each weighing about 137 tonnes with internal systems—provide an insulated environment for heat exchangers, cryogenic adsorbers, liquid helium and liquid nitrogen phase separators.
Compression station
2019-09-23 - In the liquid helium plant compression station, a narrow corridor separates the two parallel oil removal system skids. Oil is used in the helium compression process but needs to be removed entirely by a set of filters, separators, pumps etc.
Inside the cold factory
2019-09-23 - As large as two football pitches, the ITER cryoplant provides cooling fluids to 10,000 tonnes of superconducting magnets, eight massive cryopumps, and thousands of square metres of thermal shielding.
2019-09-23 - Packing the power of approximately 60 electric vehicles, this 4.5 MW motor feeds the multistage centrifugal nitrogen compressor.
Across the road
2019-05-10 - Cryogens produced in the cryoplant (left) will travel by overhead bridge to the Tokamak Complex (concrete building at right).
Outside the cryoplant
2019-03-01 - This complex set of hand valves and local readings of pressure, temperature and flow is part of the cooling loop that maintains the temperature inside the cryoplant's quench tanks at 100 K.
Cryolines in production
2018-10-24 - INOXCVA in India is producing about half of the 5 km of cryolines needed for ITER (700 "spools") for the Indian Domestic Agency. Eighty percent have all kinds of angles, bends and turns.

Three identical rows
2018-07-17 - Aligned in three rows, each one linked to a helium cold box, the helium compressors installed on tall concrete pads will supply the cold boxes with gaseous helium at 21.8 bars.
The world's largest single-platform cryoplant
2018-07-17 - Three parties are sharing responsibility for the plant's procurement: the ITER Organization, responsible for the liquid helium plants; Europe, in charge of the liquid nitrogen plant and auxiliary systems as well as the construction of the cryoplant infrastructure on site; and India, whose contractors are procuring the cryolines and cryodistribution components.
First industrial plant on site
2018-07-17 - The ITER cryoplant used to be a vast echoey chamber with 5,400 m² of interior space divided into two areas; now, it is filled from floor to ceiling with industrial equipment.
Teamwork
2018-07-17 - Close coordination is required of the different teams representing the ITER Organization, the European Domestic Agency, equipment manufacturer Air Liquide, mechanical installation contractors, and ITER's Construction Management-as-Agent.
Filling up
2018-07-17 - Most of the planned components are now installed in the Compressor Building, drastically reducing the space for circulation.
