FIELD: core members of nuclear reactors using liquid-metal primary coolant. ^ SUBSTANCE: proposed nuclear-reactor core fuel assembly has fuel elements, bottom and top spacer grids, splinting wire, and hexagonal tube with bottom nozzle. The latter has outer thread on its cylindrical part and is provided with hold-down nut. Bottom spacer grid is provided with perforated thrust ring and is split through height into two parts joined together. Slots are milled in bottom part of spacer grid along hole axes to pass fuel element splinting wire. ^ EFFECT: enhanced manufacturability and operating reliability. ^ 1 cl, 2 dwg |
