Spacing grid for nuclear fuel unit of nuclear reactor to produce thermal energy from nuclear fission, has strips assembled in shape of lattice and comprising two slits in plane, where part of strips is separated from cell or grid spring
The grid has a cell (D) or a support grid spring for a fuel rod located in an axial direction, and strips (110) assembled in a shape of a lattice. The strips comprise two slits (111) in a plane. A part of the strips is separated from the cell or the grid spring. The slits present an arcuate or curve...

description | The grid has a cell (D) or a support grid spring for a fuel rod located in an axial direction, and strips (110) assembled in a shape of a lattice. The strips comprise two slits (111) in a plane. A part of the strips is separated from the cell or the grid spring. The slits present an arcuate or curved shape extending in a side direction of the strips. Other slits are arranged at upper and lower positions. The slits are symmetrically arranged relative to a vertical direction, where the grid is placed in a direction perpendicular to the fuel rod.
La présente invention concerne une grille d'espacement pour un ensemble combustible nucléaire qui est constituée à partir de bandes (110) de grille bénéficiant d'une structure améliorée, ce qui réduit les vibrations haute fréquence induites par l'écoulement. La grille d'espacement comporte des alvéoles (D) ou des ressorts de grille pour soutenir des barres de combustible et est constituée à partir d'une pluralité de bandes (110) de grille assemblées en forme en treillis pour former des cellules de treillis. Chacune des bandes (110) de grille comporte au moins une fente (111) pratiquée dans une partie plane de la bande (110) de grille séparément de l'alvéole (D) ou du ressort de grille. Par conséquent, on peut régler de diverses manières différentes les caractéristiques de la vibration de la grille d'espacement de façon à pouvoir réduire les vibrations haute fréquence induites par l'écoulement. |
