CONTROL FUEL ASSEMBLY OF PRESSURIZED WATER REACTORS Russian patent published in 2004 - IPC

Abstract RU 2236712 C2

FIELD: nuclear power engineering.

SUBSTANCE: proposed fuel assembly designed to perform dual function of energy liberation and neutron flux control in pressurized water reactors, especially VVER-440 ones, has fuel bundle whose uranium dioxide mass is 69.16 to 159.25 kg; outer and inner diameters of fuel element are 6.00 ÷ 10-3 to 8.00 ÷ 10-3 m and 5.09 ÷ 10-3 to 6.79 ÷ 10-3 m, respectively, for bundle of 174 to 216 fuel elements, or uranium dioxide mass in bundle is 88.67 to 149.53 kg; outer and inner diameters of fuel element are 7.80 ÷ 10-3 to 8.79 ÷ 10-3 m and 6.62 ÷ 10-3 to 7.47 ÷ 10-3 m, respectively, for bundle of 132 to 168 fuel elements.

EFFECT: reduced fuel element unsealing probability, enlarged power variation range, improved heat absorption capability.
