CORE, HEAT-RELEASE ASSEMBLY AND FUEL ELEMENT FOR WATER -MODERATED NUCLEAR REACTOR
The present invention may be used in nuclear technology for developing the structures of fuel elements, heat-release assemblies constructed from said fuel elements and cores of water-cooled reactors. In this invention, the outer diameter of fuel elements as well as the diameter and mass of the fuel...

| description | The present invention may be used in nuclear technology for developing the structures of fuel elements, heat-release assemblies constructed from said fuel elements and cores of water-cooled reactors. In this invention, the outer diameter of fuel elements as well as the diameter and mass of the fuel core are selected from specific ranges depending on the nominal thermal capacity of the reactor.The heat-release assemblies, which contain a bundle of fuel elements, are characterised by fuel element shells of varying dimensions and by the varying fuel mass in the bundle depending on the predetermined number of fuel elements and on the reactor's nominal thermal capacity. The reactor cores formed from the heat-release assemblies are manufactured taking account of the reactor's thermal capacity, of the water-uranium ratio and of the number of fuel elements in said heat-release assemblies. The reactor cores contain fuel elements whose shells have outer and inner diameters of different sizes. |
