FUEL ASSEMBLY FOR PRESSURIZED-WATER POWER REACTOR Russian patent published in 2003 - IPC

Abstract RU 2198439 C2

FIELD: nuclear power engineering. SUBSTANCE: fuel assembly has fuel rods assembled in bundle. Fuel rods are provided with pressurizer between butt-end of fuel pile and one of plugs. Pressurizer accommodates locking spring. Some of fuel rods are disposed in fuel assembly having pressurizer in top part of bundle and other ones, in fuel assembly with pressurizer in bottom part of bundle. Length of active part of bundle increases by pressurizer length. EFFECT: provision for organizing areas with enhanced water-to-uranium ratio in top and bottom ends of fuel bundles. 4 cl, 4 dwg
