Similar arguments can be made concerning the shape of a reactor. It can be shown that for a given volume of fuel and moderator a sphere always has the smallest leakage. A sphere is not a practical shape from an engineering point of view. Instead, we use a cylindrical reactor core that has the diameter slightly bigger than the length. The actual shape is a compromise between engineering and nuclear considerations.

CONT

Des arguments semblables peuvent être invoqués en ce qui concerne la forme du réacteur. Il peut être démontré que pour un volume donné de combustible et de modérateur, une sphère comporte toujours le pourcentage de fuite le plus faible. Mais une sphère n'est pas une forme pratique du point de vue technique. Plutôt, nous utilisons un coeur de réacteur cylindrique qui possède un diamètre légèrement supérieur à sa longueur. La forme réelle est un compromis entre des considérations techniques et nucléaires.
