NUCLEAR REACTOR FUEL ASSEMBLY Russian patent published in 2000 - IPC

Abstract RU 2152089 C1

FIELD: nuclear power engineering. SUBSTANCE: fuel assembly has head 1 and shank 2 interconnected through guide channels 3 as well as metering channel 4 and absorbing rods 5 placed in guide channels and suspended from brackets 6 of respective movable yoke 7. Guide channels 3 and metering channel 4 are arranged among fuel elements 8 vertically mounted in spacer grids 9. Metering channel 4 has entrance 10 on top to pass metering probe 11; it is arranged between projections of brackets 6 on yoke 7 for absorbing rods 5 onto cross-sectional area of fuel assembly. Metering probe provides for reliable monitoring of coolant conditions and neutron flux density in reactor core. EFFECT: improved safety of reactor. 2 dwg
