Lower end-piece with baffle anti-debris device for a nuclear fuel assembly, and corresponding assembly

摘要

The end fitting has a lower plate (43) forming a debris control device for delimitating water flow channels (47) arranged in nodes of a regular network, and orientation noses (39) arranged in part in the channel for delimitating water passages (51) with the channels. The water passages comprise two sections (S1, S2), which are radially moved each other with respect to the nodes corresponding to the regular network for forming a baffle (56).
