Correlation between properties and irradiation behavior for carbide, carbonitride and nitride fuels

A description is presented of the general fuel and pin behaviour on the basis of the presently available information of the project and is organized in the following way: the results of an analysis of the complex system reactor-cladding-fuel in order to fix the parameters and their range of values in the problem of swelling; a description of the general pin behaviour follows as obtained from intermediate and final measurements of the permanent diameter increases (ΔD/D) of the fuel pins; a detailed description of fuel restructuring and its correlation with the basic fuel properties; and the results are summarized and conclusions drawn about the potential of the various types of fuels and pins with regard to fuel composition
