NUCLEAR REACTOR FUEL ELEMENT Russian patent published in 2000 - IPC

Abstract RU 2150150 C1

FIELD: water-moderated reactors. SUBSTANCE: fuel element is designed for organizing core of VVER-1000 water-moderated power reactor. Fissionable-products gas collector of fuel element has cylindrical spring for holding fuel pile in position. Spring has locking, damping, and compensating groups of turns with certain ratio of compensating and damping groups to total length of spring in released state. With gas collector length being rather great spring occupies only some portion of its space; number of compensating and damping groups is strictly regulated; diameter of turn wire is 0.9 to 1.3 mm. EFFECT: improved service life and fuel burn-up. 8 cl, 2 dwg
