… the moderator and coolant [are] separated by two tubes with a donut shaped space (annulus) between them. The calandria tubes, about six meters long, are the walls of the channels through the calandria. The pressure tubes, placed inside the calandria tubes, each contain 12 or 13 fuel bundles. The gas in the space between the tubes, the annulus gas, insulates the cool moderator from the hot heat transport system.

[…] le modérateur et le caloporteur […] se présentent dans des circuits distincts séparés par deux tubes dans un espace en forme de beigne (espace annulaire). Les tubes de calandre, d’environ 6 mètres de longueur, sont les parois des canaux de la calandre. Les tubes de force, placés à l'intérieur des tubes de calandre, renferment chacun 12 ou 13 grappes de combustible. Le gaz contenu dans l’espace entre les tubes, appelé gaz annulaire, isole le modérateur froid du circuit caloporteur chaud.
