Title (EN) RADIAL NEUTRON REFLECTOR
(FR) RÉFLECTEUR DE NEUTRONS RADIAL
Abstract:
(EN) A nuclear reactor core comprising fissile material is surrounded by a core former. The core former comprises one or more single-piece annular rings wherein each single-piece annular ring comprises neutron-reflecting material. In some embodiments the core former comprises a stack of two or more such single-piece annular rings. In some embodiments the stack of single-piece annular rings is self-supporting. In some embodiments the stack of single-piece annular rings does not include welds or fasteners securing adjacent single-piece annular rings together. A core basket may contain the nuclear reactor core and the core former, and in some embodiments an annular gap is defined between the core former and the core basket. In some embodiments the core former does not include welds and does not include fasteners.
(FR) Un cœur de réacteur nucléaire comprenant une matière fissile est entouré d'un dispositif de formation de cœur. Le dispositif de formation de cœur comprend une ou plusieurs bagues annulaires monoblocs, chaque bague annulaire monobloc comprenant une matière réfléchissant les neutrons. Dans certains modes de réalisation, le dispositif de formation de cœur comprend une pile de deux ou plus de deux desdites bagues annulaires monoblocs. Dans certains modes de réalisation, la pile de bagues annulaires monoblocs est autoportante. Dans certains modes de réalisation, la pile de bagues annulaires monoblocs ne comprend pas de soudure ni d'élément de fixation pour la fixation des bagues annulaires monoblocs adjacentes les unes aux autres. Un panier de cœur peut contenir le cœur du réacteur nucléaire et le dispositif de formation de cœur et, dans certains modes de réalisation, un espace annulaire est défini entre le dispositif de formation de cœur et le panier de cœur. Dans certains modes de réalisation, le dispositif de formation de cœur ne comprend pas de soudure ni de dispositif de fixation.
