NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 1997 - IPC

Abstract RU 2079170 C1

FIELD: nuclear power engineering. SUBSTANCE: fuel assembly has bundle of fuel elements assembled in can built up of spacing grids and tubular channels secured at bottom ends, together with fuel elements, in bottom grid; it also has head mounted on top ends of tubular channels and tail end. The latter has supporting ribs for bottom grid connected to the latter by means of adapters. The latter are made in the form of flat plates secured on two opposite side edges of bottom grid in parallel to supporting ribs abutting bottom grid between rows of fuel element cells. Fuel elements are provided with bottom plugs are longitudinally cut into parts which are mechanically set apart for holding fuel elements against longitudinal displacement upwards relative to bottom grid, including after pre-connection of tail end to this grid. EFFECT: improved design. 2 cl, 2 dwg
