ТЕПЛОВЫДЕЛЯЮЩАЯ СБОРКА (ВАРИАНТЫ)

摘要

FIELD: power engineering; heat-generating installations such as nuclear power units. ^ SUBSTANCE: proposed fuel assembly has fuel elements and swirling devices. The latter are mounted in a spaced relation to convex heat-transfer surfaces of fuel elements. These spaces or clearances are formed due to attachment of swirling devices to spacer grids. ^ EFFECT: enhanced specific power of fuel assembly. ^ 5 cl, 2 dwg
