Characterization of mechanically alloyed yttria dispersed 9cr martensitic steel

Abstract

Generation IV nuclear energy systems are an ensemble of nuclear newlinereactor technologies that present significant improvements in economics newlinesafety and reliability and sustainability over currently operating reactor newlinetechnologies Proper choices of cladding and structural material are essential newlinefor the safe and reliable operation of any Generation IV system Studies to newlinedevelop optimum combination of properties for steels intended for use as newlinewrappers indicated that 912Cr type ferritic steels presented superior high newlinetemperature strength at temperatures below 873 K and excellent dimensional newlinestability at high displacement doses The development of FerriticMartensitic newline912Cr steels with Reduced Activation RAFM steels for nuclear fusion newlinewas based on the excellent irradiation performance of 912 Cr steels in Fast newlineBreeder Reactors newline newline
