Изобретение относитс  к технике  дерных реакторов .This invention relates to nuclear reactor technology.

В известной топливной сборке  дерного реактора верхн   и нижн   концевые детали, соединенные трубчатыми каналами, образуют жесткий каркас, на котором с помощью решетки закреплены тепловыдел ющие элементы. В трубчатых каналах размещены регулирующие стержни, закрепленные на траверсе.In the known nuclear reactor fuel assembly, the upper and lower end pieces, connected by tubular channels, form a rigid frame on which the heat release elements are fixed to the grid. In the tubular channels placed control rods mounted on the traverse.

Однако известна  конструкци  сборки не позвол ет производить дистанционную замену или перестановку с одной топливной сборки на другую регулирующих стержней или стержней с выгорающим поглотителем в реакторе.However, the known assembly design does not allow remote replacement or transfer from one fuel assembly to another regulating rods or rods with a burnable absorber in the reactor.

Цель изобретени  - обеспечение возможности дистанционной замены пучка регулирующих стержней .The purpose of the invention is to provide the possibility of remote replacement of a bundle of control rods.

Цель достигаетс  тем, что в предлагаемой топливной сборке между верхними открытыми концами трубчатых каналов и траверсой пучка регулирующих стержней размещен перемещаемый при необходимости в продольном направлении (относительно регулирующих стержней и головки сборки) стакан с отверсти ми дл  регулирующих стержней и продольными пазами дл  центрировани  и стыковки с топливной сборкой.The goal is achieved by the fact that in the proposed fuel assembly between the upper open ends of the tubular channels and the beam of control rods is placed, if necessary, in a longitudinal direction (relative to the control rods and the head of the assembly) a glass with holes for the control rods and longitudinal grooves for centering and docking fuel assembly.

На фиг. 1 изображен общий вид топливной сборки; на фиг. 2 - стакан дл  замены или перестановки регулирующих стержней в двух проекци х с разрезами .FIG. 1 shows a general view of the fuel assembly; in fig. 2 - a cup for replacing or swapping the control rods in two projections with cuts.

Топливна  сборка включает верхнюю 1 и нижнюю 2 концевые детали, в рещетки которых 3 и 4 заделаны направл ющие каналы 5. На каналах закреплены решетки 6, с помощью которых установлены тепловыдел ющие элементы 7. В направл ющих каналах размещены регулирующие стержни 8, закрепленные на траверсе 9, котора  при необходимости перемещаетс  в продольном направлении с помощью специального приспособлени .The fuel assembly includes the upper 1 and lower 2 end parts, in the lattices of which 3 and 4 the guide channels 5 are sealed. The channels are fixed on the grating 6, which are used to install the heat release elements 7. The control rods 8 are mounted on the cross bar 9, which, if necessary, is moved in the longitudinal direction with the help of a special tool.

Между траверсой 9 и открытыми концами направл ющих каналов 5 установлен стакан 10 дл  замены или перестановки регулирующих стержней, через отверсти  плиты которого с необходимым зазором проход т регулирующие стержгш. На поверхности стакана имеютс  пазы дл  его фиксации в головке топливной сборки.Between the crosshead 9 and the open ends of the guide channels 5, a cup 10 is installed to replace or reposition the control rods, through which the control rods pass with the required clearance. On the surface of the glass there are grooves for fixing it in the head of the fuel assembly.

Дистанционна  замена или перестановка пучка стержней с одной топливной сборки на другую в реакторе осуществл етс  с помощью телескопической штанги перегрузочной машины.The remote replacement or rearrangement of a bundle of rods from one fuel assembly to another in the reactor is carried out using a telescopic rod of the reloading machine.
