SFR ASSEMBLY FOR A NUCLEAR REACTOR OF SFR TYPE WITH REVERSIBLE WELDLESS CONNECTION BETWEEN THE ASSEMBLY CASING AND AN ASSEMBLY ELEMENT INSERTED INTO THE CASING

摘要

The present application relates to an assembly to be inserted into a nuclear reactor, especially a liquid sodium-cooled fast neutron reactor SFR. The assembly includes: an assembly hollow body (12) which is in an elongate shape along a longitudinal axis (X), wherein the wall of the hollow body (12) includes at least one open-ended opening; an assembly element (14) which is at least partially inserted into the hollow body (12), wherein the assembly element (14) includes at least one flexible blade (20) of which the free end is in the shape of a clip-fastening hook (21) clip-fastening and collaborating with the open-ended opening from the inside of the hollow body so as to connect the assembly element to the hollow body; and at least one removable locking means which is to lock the flexible blade (20) clip-fastened to the open-ended opening (122), wherein the removable locking means makes it possible to prevent the flexible blade from being bent to lock a connection part between the assembly element (14) and the hollow body (12).
