Abstract

1. Имитатор тепловыделяющего элемента ядерного реактора, включающий оболочку и трубчатый электронагревательный элемент с переменной толщиной стенки, размещенный внутри оболочки, электроизоляционный материал между оболочкой и трубчатым электронагревательным элементом, а также порошкообразный наполнитель из материала ядерного топлива внутри трубчатого электронагревательного элемента, отличающийся тем, что, с целью повышения точности имитации поведения тепловыделяющего элемента ядерного реактора в аварийных ситуациях с высокими удельными энерговыделениями, приводящими к расплавлению ядерного топлива, выходу его из-под оболочки и взаимодействию расплавленного ядерного топлива с жидкометаллическим теплоносителем, внутри трубчатого электронагревательного элемента по его оси размещен другой электронагревательный элемент в виде стержня из тугоплавкого металла, на конце которого в зоне минимальной толщины стенки трубчатого электронагревательного элемента закреплена таблетка ядерного топлива с обеспечением ее электрического контакта со стержнем.2. Имитатор по п.1, отличающийся тем, что таблетка ядерного топлива выполнена с центральным отверстием конической формы, сужающимся к нижнему торцу.1. Simulator of a fuel element of a nuclear reactor, comprising a shell and a tubular electric heating element with variable wall thickness, placed inside the shell, an electrical insulating material between the shell and the tubular electric heating element, as well as a powdery filler of nuclear fuel material inside the tubular electric heating element, characterized in that to improve the accuracy of simulating the behavior of a fuel element of a nuclear reactor in emergency situations with high beats With the use of heat, the melting of nuclear fuel, its release from under the shell and the interaction of molten nuclear fuel with liquid metal coolant, inside the tubular electric heating element, another electric heating element is placed along its axis in the form of a refractory metal rod, at the end of which in the zone of minimum wall thickness tubular electric heating element fixed tablet of nuclear fuel to ensure its electrical contact with the rod.2. The simulator according to claim 1, characterized in that the tablet of nuclear fuel is made with a central hole of conical shape, tapering to the lower end.
