Abstract

Un ensemble réflecteur de neutrons pour l'espace irrégulier (13) situé dans un réacteur nucléaire entre un faisceau (5) d'assemblages combustibles linéaires allongés (3) à travers lequel circule un réfrigérant et une enveloppe de noyau circulaire (7) entourant le faisceau, est constitué d'une pluralité de modules (15) comportant chacun un raidisseur allongé (21) et une pluralité de plaques allongées (23) assemblés le long de leurs bords longitudinaux pour former une enceinte allongée (17) dans laquelle sont disposés des réflecteurs de neutrons, destinée à etre insérée dans l'espace irrégulier (13).
