ABSTRACT:
A pressurized water nuclear reactor with solid partitioning comprises a core formed by assemblies of prismatic shape disposed side by side inside a vertical cylindrical casing. A space between the core and the casing receives a solid partitioning structure. The partitioning is formed as a vertical stack of rings each completely surrounding the core, whose external periphery is engaged with a clearance in the casing and whose internal periphery matches the external contour of the core. The rings are centered and indexed with respect to the core casing by keys fixed to the casing and projecting into vertical grooves formed in the rings and they are formed with vertical mutually aligned holes defining cooling channels. Plugs in the channels define restricted water flow passages.
