Abstract

1. Тепловыделяющая сборка активной зоны быстрого ядерного реактора, охлаждаемого тяжелым жидкометаллическим теплоносителем, содержащая хвостовик, головку, очехловывающую трубу и твэлы, отличающаяся тем, что упомянутые хвостовик, головка, очехловывающая труба выполнены из материалов, имеющих плотность большую, чем у теплоносителя и исключающих плавучесть тепловыделяющей сборки в данном теплоносителе.2. Тепловыделяющая сборка по п.1, отличающаяся тем, что объем хвостовика, за исключением центрального канала прокачки теплоносителя, заполнен материалом, имеющим плотность большую, чем у теплоносителя, например вольфрамом, платиной, ураном.3. Тепловыделяющая сборка по п.1, отличающаяся тем, что в качестве топлива в твэлах возможно использование, например, карбидов и нитридов урана.1. Fuel assembly of the core of a fast nuclear reactor cooled with a heavy liquid metal coolant, containing a liner, a head, a casing pipe and fuel rods, characterized in that the said liner, a head, a casing pipe are made of materials having a density greater than that of the coolant and excluding buoyancy a fuel assembly in a given coolant. 2. The fuel assembly according to claim 1, characterized in that the volume of the shank, with the exception of the central channel for pumping the coolant, is filled with a material having a density greater than that of the coolant, for example, tungsten, platinum, uranium. Fuel assembly according to claim 1, characterized in that it is possible to use, for example, uranium carbides and nitrides as fuel in the fuel elements.
