“…The presence of several crystallographic variants of G-phase observed in this work is in good agreement with the results obtained by Thomas et al [15]. The predominance of this phase in SA 316 compared to CW 316 is also reported by Maziasz [37].…”

“…Its lattice parameter measured from lattice images is estimated to be 11.64 Å [5]. This value is similar to those reported in the literature [5,[13][14][15][16][17][18][19][20]. c 0 precipitates are smaller and more numerous than s/g carbides and G-particles.…”

“…Since swelling is very sensitive to irradiation conditions, such as temperature and dose rate, swelling data are very scarce in PWR-relevant low-doserate, low-temperature conditions (10 −10 -10 −8 dpa/s, >20 dpa, 300-370 • C). Figure 29 shows the swelling data from PWR-irradiated SSs and MTR-irradiated SSs at LWR-relevant temperatures [218,[340][341][342][343][344][345][346][347]. The data show different trends in swelling evolution with morphology (bubble vs. void), reactor type (PWR vs. FBR) and materials (304 vs. others).…”

Current phenomenological knowledge and understanding of mechanisms are reviewed for radiation embrittlement of reactor pressure vessel low alloy steels and irradiation assisted stress corrosion cracking of core internals of stainless steels. Accumulated test data of irradiated materials in light water reactors and microscopic analyses by using state-of-the-art techniques such as a three-dimensional atom probe and electron backscatter diffraction have significantly increased knowledge about microstructural features. Characteristics of solute clusters and deformation microstructures and their contributions to macroscopic material property changes have been clarified to a large extent, which provide keys to understand in the degradation mechanisms. However, there are still fundamental research issues that merit study for long-term operation of reactors that requires reliable quantitative prediction of radiation-induced degradation of component materials in low-dose rate high-dose conditions.

“…The cavities formed in the present materials are thought to be fine helium bubbles since the morphology, size and density were quite similar to those reported as helium bubbles. [21][22][23] These were identified in all the irradiation conditions whereas no void was observed. The difference of 30 K (565 vs. 595 K in samples C vs. D and G vs. H) in similar dose and dose rate condition caused no notable changes in cavity morphology.…”

The evolution of microstructures and microchemistry was examined by transmission electron microscopy in coldworked SUS 316 stainless steel components irradiated in a pressurized water reactor to 1-73 dpa at 565-596 K. Homogenous nucleation of dislocation loops, helium bubbles and 0 precipitates was detected. The dislocation loops consisted of a high density of Frank loops and black dots. The black dots are considered to be small Frank loops, some fraction of which could be vacancy-type. The size distribution showed a double peak, which remained unchanged up to 73 dpa, suggesting that the dislocation structure was saturated under a balance of nucleation and disappearance. The helium bubbles were extremely dense and fine, resulting in swelling of less than 0.1%. Such bubble structure was formed under irradiation with a high He/dpa ratio. The 0 precipitation was detected at doses higher than 4 dpa with an increasing density for higher doses. The measured radiation hardening was almost explained by these visible microstructural features. Radiation-induced segregation at grain boundaries was confirmed to continuously develop up to 73 dpa whereas no significant segregation could be detected at Frank loops.
