Metal-Based Matrix Materials

One of the components of the fuel composition of dispersion nuclear fuel is a non-fissile material (matrix), which ensures its high radiation resistance.Despite the fact that dispersion nuclear fuel is used in reactors of various purposes (research, power, nuclear power plants, etc.), the operating conditions of which vary significantly, there are a number of requirements that must be taken into account when choosing the matrix material.Metals (aluminum and zirconium, as well as their alloys) have found wide application as matrix material in the production of dispersion-type fuel elements for research reactors and reactors of naval nuclear power plants (NPPs).Stainless steel matrix is used in dispersion nuclear fuel in power reactor plants.
