FIELD: nuclear engineering.
SUBSTANCE: fuel assembly contains tailpiece, the casing of which is made in the form of shell and has cylindrical portion. Elastic ring is installed on external surface of the latter. Openings for coolant entry are provided in the inlet conical part. Tailpiece is equipped with anti-debris filter installed in the casing of tailpiece higher than the openings for coolant passage. Elastic ring is arranged in the form of bushing. Middle part of bushing has barrel shape, at that cuts are provided in the bushing, which are directed along the bushing axis.
EFFECT: possibility of debris particles ingress inside fuel assembly reduces as well as vibration effect of coolant flow at fuel elements.
