FUEL ASSEMBLY OF NUCLEAR REACTOR Russian patent published in 2008 - IPC G21C3/30

Abstract RU 2339093 C2

FIELD: physics.

SUBSTANCE: fuel assembly of a nuclear reactor consists of batch of fuel elements and guide channels, installed in spacer grids, head section and end section. The spacer grids are joined together as well as with the end section by elements, located along the length of the fuel assembly. The end section consists of a bedplate and a support body joined together. On top of the bedplate there is an anti-vibration grid, consisting of cells joined together. The anti-vibration grid, bedplate and the support body are joined together by at least one fastening element.

EFFECT: longer lifespan of the fuel element and fuelling and increased burn up fraction of the fuel.
