Abstract
The upper part of the vessel (3) is cooled as a result of the circulation of cooled sodium (27). The cooled sodium coming form the lower part of the reactor core is introduced into a first collector (15) via pipes (17) and then overflows into a second collector (16). The second collector (16) or return collector is delimited by an overflow sleeve (18) and by an inner sleeve (21), the height of which is substantially less than the height of the overflow sleeve (18). The lower part of the inner sleeve (21) is connected to the overflow sleeve (18) by an annular plate (22) ensuring the stiffening of the sleeve (18). The height of the sleeve (21) is preferably between one-third and third of the height of the sleeve (18). This prevents vibrations from being generated during the circulation of the sodium.
