Abstract

FIELD: nuclear power engineering. SUBSTANCE: fuel assembly has hexagonal bundle of fuel elements placed in spacers arranged through height of fuel assembly, head and tail parts interconnected by guide channels passing through spacers; stamped zirconium-alloy angle plates are installed at fuel assembly corners through its height from tail part to top spacer; they are welded to spacers and screwed to tail part. EFFECT: improved reactor safety due to better stiffness of fuel assembly at same economic efficiency, reduced fuel assembly variations and reduced linear load on fuel element.

Изобретение относится к атомной энергетике, в частности к тепловыделяющим сборкам энергетических ядерных реакторов. Задачей изобретения является повышение безопасности ядерного реактора путем повышения жесткости тепловыделяющей сборки при сохранении ее положительных качеств (экономичности, уменьшенной неравномерности по ТВС и уменьшенной величины линейной нагрузки твэл). Решение задачи обеспечивается тем, что в известной тепловыделяющей сборке ядерного реактора, содержащей гексагональный пучек тепловыделяющих элементов, размещенный в расположенных по высоте сборки дистанционирующих решетках, головную и хвостовую части, соединенные направляющими каналами, проходящими через дистанционирующие решетки, в углах ТВС по ее высоте от хвостовой части до верхней дистанционирующей решетки установлены штампованные угловые пластины из циркониевого сплава, соединенные сваркой с дистанционирующими решетками и винтами с хвостовой частью.The invention relates to nuclear energy, in particular to fuel assemblies of nuclear power reactors. The objective of the invention is to increase the safety of a nuclear reactor by increasing the rigidity of the fuel assembly while maintaining its positive qualities (profitability, reduced unevenness in the fuel assemblies and reduced linear load of the fuel elements). The solution is provided by the fact that in the known fuel assembly of a nuclear reactor containing a hexagonal bunch of fuel elements located in the spacing grids located along the height of the assembly, the head and tail parts are connected by guide channels passing through the spacing grids in the angles of the fuel assembly along its height from the tail parts to the upper spacer grid are mounted stamped corner plates of zirconium alloy, connected by welding to the spacer grids and intami tailed.
