Abstract
1. Способ работы тепловыделяющей сборки на входном участке, заключающийся в подаче теплоносителя на вход тепловыделяющей сборки, пропускании теплоносителя вдоль выпуклых теплоотдающих поверхностей тепловыделяющих элементов, установленных в трубной доске, отвода с выпуклых теплоотдающих поверхностей тепла, выделенного в тепловыделяющих элементах, отличающийся тем, что после прохождения трубной доски теплоноситель закручивают с помощью нетепловыделяющих имитаторов тепловыделяющих элементов, выполненных в виде самодистанционирующихся плотноупакованных закрученных стержней, пристыкованных к тепловыделяющим элементам, причем длина имитаторов не менее 1/3 шага закрутки. ! 2. Устройство для осуществления работы тепловыделяющей сборки на входном участке, содержащее входную и выходную камеры, корпус, в котором размещены тепловыделяющие элементы, фиксированные в нижней части в трубной доске и дистанционированные по высоте с помощью дистанционирующих решеток, отличающееся тем, что тепловыделяющие элементы на участке от выхода из трубной доски до начала зоны тепловыделения снабжены нетепловыделяющими имитаторами тепловыделяющих элементов, пристыкованными к тепловыделяющим элементам и установленными в трубной доске, причем нетепловыделяющие имитаторы тепловыделяющих элементов выполнены в виде самодистанционирующихся плотноупакованных закрученных стержней, длина имитаторов не менее 1/3 шага закрутки. 1. The method of operation of the fuel assembly at the inlet section, which consists in supplying the coolant to the inlet of the fuel assembly, passing the coolant along the convex heat-releasing surfaces of the fuel elements installed in the tube plate, removing the heat released from the convex heat-releasing surfaces from the convex heat-releasing surfaces, characterized in that after passing through the tube sheet, the coolant is twisted using non-heat-generating simulators of fuel elements made in the form of self-spaced close-packed twisted rods attached to the fuel elements, the length of the simulators being at least 1/3 of the twist pitch. ! 2. A device for carrying out the operation of the fuel assembly at the inlet section, containing the inlet and outlet chambers, a housing in which the fuel elements are located, fixed in the lower part in the tube sheet and spaced in height by means of spacer grids, characterized in that the fuel elements in the section from the exit from the tube sheet to the beginning of the heat release zone, they are equipped with non-heat-generating simulators of fuel elements, docked to the fuel-generating elements and installed in the tube-sheet, and the non-heat-generating simulators of fuel elements are made in the form of self-spaced close-packed twisted rods, the length of the simulators is less than 1/3 of the swirling rods.
