Abstract

Procédé d'accroissement de la réactiyité dans des réacteurs nucléaires thermiques et épithermiques par l'utilisation d'éléments lourds. Selon la présente invention, un accroissement de la réactivité dans des réacteurs thermiques et épithermiques peut être obtenu par l'utilisation d'éléments lourds disposés en des emplacements choisis dans les réacteurs et permettant d'obtenir, notamment, des réductions de coût de fonctionnement par réduction des quantités d'eau lourde nécessaires dans les réacteurs à modérateur à base d'eau lourde et par la réduction de l'enrichissement nécessaire dans les réacteurs à eau légère. Application à des réacteurs nucléaires thermiques et épithermiques.
