Abstract
A partitioning device is provided which can be used in a pressurized water nuclear reactor. It occupies the space between the prismatic shaped core of the reactor, and a cylindrical casing and comprises vertical partitioning plates surrounding the core and reinforcement elements placed between the partitioning plates and the casing. It comprises panels distributed into horizontal rows in vertical columns, all the panels of the same row being identical and having vertical partitioning plates welded together and fast with criss-crossed horizontal and vertical reinforcements bearing on the casing and with vertical tubes. The stacked tubes of a same column form a post resting on a core support plate. Solid vertical keys connect the panels in the different columns together and to the casing.
