“…9Cr-1Mo) ferritic/martensitic steel was suitable as a candidate material since its mechanical strength was larger than those of austenitic steels 3,4) and its corrosion damage by LBE was relatively smaller than those of other materials. 5) It was also confirmed that the buckling failure was the most critical in the structural design. The optimization of the shape of the beam window to prevent the buckling failure was performed under the unirradiated condition.…”

The conceptual design study of the beam window of the spallation target is one of the critical issues in the R&D of the accelerator-driven system (ADS). In this study, the investigation to create a feasible concept of the beam window for the ADS was performed by changing the proton beam profile from the Gaussian distribution to the parabolic and the flat distributions. Detailed analyses were performed by considering the particle transport of protons and neutrons in the spallation target region, the thermal hydraulics of lead bismuth eutectic (LBE) around the beam window, and the structural strength of the beam window. The calculation results showed that the difference in the temperature between the inner and outer surfaces at the top of the beam window was reduced by changing the beam profile from the Gaussian to the parabolic and the flat distributions. By this reduction, in the parabolic case, the thermal stress at the top position was also reduced and the buckling pressure increased by about 20%. On the other hand, in the flat case, the thermal stress at the peripheral region instead of at the central position increased and the buckling pressure slightly deteriorated. The buckling mode was also changed in the flat case. From these calculation results and discussions, it was confirmed that all three cases, the Gaussian, the parabolic, and the flat, were feasible and it was concluded that the concept with the parabolic distribution would be the most feasible under the current ADS design condition.

“…Controlling oxygen concentration in LBE can form a self-healing oxidation layer on the steel surface. The continuous and stable oxide layer can ease the corrosion and dissolution attack from LBE [7]. So, the technologies of monitoring and controlling the oxygen concentration in LBE have become critical issues [1,7].…”

Abstract:In order to investigate the compatibility of the candidate structural materials with liquid metals, two kinds of ferritic/martensitic steels were chosen to contact with lead-bismuth eutectic in sealed quartz glass tubes. The corrosion process lasted for 500 h and 3000 h. Results showed that the oxidation layer and carbide dissolution layer on the two steels grew with contact time under oxygen unsaturated condition. Short-term corrosion behavior of SIMP showed better lead-bismuth eutectic corrosion resistance than T91 at 873 K.
