Pour un réacteur à l'uranium naturel qui utilise du dioxyde d'uranium, seule l'eau lourde constitue un modérateur adéquat. Le choix des volumes relatifs de combustible et de modérateur ainsi que leur configuration géométrique déterminent l'efficacité neutronique. 2, record 2, French, - efficacit%C3%A9%20neutronique
