THERMAL ELECTRICAL ASSEMBLY OF NUCLEAR REACTOR Russian patent published in 2017 - IPC G21C3/00 

FIELD: power industry.

SUBSTANCE: invention relates to fuel assemblies (fuel assemblies) of VVER-type nuclear reactors (VVER-440, VVER-1000, etc.). The anti-debris filter of the proposed FA is made in the form of a thick plate having a conical shape on the side of the heat carrier inlet with an obtuse angle at the apex directed towards the het carrier flow, on the periphery of which an annular groove is formed, forming together with the inner surface of the shank an annular depression somewhat concentric with the longitudinal axes of the fuel assembly of rows of evenly spaced channels in the circumferential direction for passage of the heat carrier curved in the circumferential direction to provide the opacity of the filter in the direction of the longitudinal axis of the fuel assembly, and the flat shape on the outlet side of the heat carrier.

EFFECT: increased efficiency in relation to the capture of debris objects both curvilinear and rectilinear.
