In this work, an integrative approach that eases the material selection stage is presented. Twenty different specifications of materials from 1st to 4th generation of pressurized water reactors have been analyzed, covering the main designs of pressurized reactors from Western Europe, Japan and Russia. Thus, the results show that steels 15Kh2MFAA, 20MnMoNi55 and SA533 Gr.B Cl.1 are the best material options to prevent the embrittlement induced by radiation… See all…
