Post-irradiation examination on LiSoR 3 experiment

Tensile tests and TEM investigations on LiSoR-2 to -4

“…An oxide layer of a few microns was formed on the surface in the irradiation zone of the ITS-specimen [4]. The surface analysis results of LiSoR-3 are reported elsewhere in the same proceedings [5]. In the present paper, results on the changes in the mechanical properties and microstructure of LiSoR-2 to -4 will be described.…”

“…The detailed information of LiSoR experiments was presented in [2][3][4][5]. Therefore, in this paper only a brief summary is given as listed in Table 1.…”

“…1 shows a part of the ITS-specimen (lower), the irradiation dose distribution along the central line calculated from the c-mapping result (middle), the sample cutting plan and the tensile samples obtained (upper). The LiSoR-3 and LiSoR-4 samples were cut out of both TS-tubes and ITS-specimens and the cutting plan was slightly different from that of LiSoR-2 [5].…”

Effects of Radiation-Induced Defects on Corrosion

“…Several studies observed no corrosive attack on these steel samples but found oxide layers that were either thicker in the irradiated zone (>200 h exposure; e.g., 125,126) or limited to that zone for short irradiation times (127). The oxides were duplex structured (with a Cr-rich inner oxide and Fe-rich outer oxide) for both MANET II (127) and T91 (128) samples.…”

“…The oxides were duplex structured (with a Cr-rich inner oxide and Fe-rich outer oxide) for both MANET II (127) and T91 (128) samples. These studies (125)(126)(127)(128) conclude that the differences between the irradiated and unirradiated regions are due to beam heating. Gavrilov et al (129) analyzed 316L and T91 specimens irradiated up to 9.1 dpa in the BOR-60 reactor in contact with LBE (350°C) as part of the LEXUR-II project and found no evidence of corrosion attack, but rather evidence for a submicrometer oxide layer.…”
