The nuclear reactor comprises a core consisting of assemblies of prismatic shape (14) arranged side by side inside an enclosure (12) of cylindrical shape with a vertical axis providing between the core and the enclosure a space in which is arranged a massive baffle assembly (16). The baffle assembly consists of a vertical stack of rings, each completely surrounding the core, whose outer periphery fits with a clearance (j) into the enclosure (12) and whose inner periphery closely matches the outer contour of the core, the said rings being centred in relation to the enclosure of the core by keys (20) attached to the enclosure and projecting into vertical grooves (22) of the rings and being pierced with aligned vertical holes defining cooling channels containing plugs allowing annular water circulation passages to subsist. …<IMAGE>… |
