Static corrosion of candidate alloys for the lead-bismuth fast reactor
… mechanisms of two candidate alloys for use in Lead-bismuth Eutectic (LBE) cooled fast nuclear reactors. The two alloys examined were T91 and Fe-12Cr-2Si. An experimental study was performed to analyze the static corrosion on the two alloys. For the experiment, the polished samples of the two …

Study of geometry effects on local corrosion rates for Lbe loop
… material, which has resistance to corrosive Lead Bismuth Eutectic (LBE). A Delta Loop was designed and constructed in Los Alamos National Lab (LANL) to obtain the experimental data. This loop is a multi-section closed system that differs in diameter from one part to another. As a result, an …

Material Corrosion by Nuclear Reactor Coolants
… reactor (BWR) coolant, high-temperature steam, lead-bismuth eutectic (LBE), and molten salt. Novel cladding materials for accident tolerant fuel (ATF) and additive manufacture (AM) Ni-based alloy were studied in water coolants. Similarly, the ATF material and Ni-based alloys were also examined …

Calibration of YSZ sensor for the measurement of oxygen concentration in Lbe
Although liquid lead-bismuth eutectic (LBE) is a good candidate for coolant in the sub-critical transmutation blanket, it is known to be corrosive to stainless steel tubes and containers used in nuclear installations. To prevent the long-term corrosion problem by producing and maintaining a …

Thermal analysis of uranium zirconium hydride fuel using a lead-bismuth gap at LWR operating temperatures
… the fuel that is coming from fission. This can lead to lower operating temperatures which will reduce the amount of fission gas release to negligible quantities, eliminate cracking, and reduce the internal energy of the fuel. Furthermore, it is hoped the UZH will be better able to attain higher …

The design of a functionally graded composite for service in high temperature lead and lead-bismuth cooled nuclear reactors
A material that resists lead-bismuth eutectic (LBE) attack and retains its strength at 700°C would be an enabling technology for LBE-cooled reactors. No single alloy currently exists that can economically meet the required performance criteria of high strength and corrosion resistance. A …

Silicon carbide performance as cladding for advanced uranium and thorium fuels for light water reactors
… relatively large during in-core service. This leads to higher fuel temperature during irradiation. In order to reduce the high fuel temperature during operation, the following fuel design options were investigated in this study: using beryllium oxide (BeO) additive to enhance fuel thermal …

The electrical impedance responses of protective oxide scales on stainless steels that are immersed in molten lead-bismuth-eutectic alloy at temperatures up to 600°C
… steel, when the steel was immersed in molten lead-bismuth-eutectic alloy (LBE) at high temperatures (up to 600°C). LBE is a candidate coolant for future fast-neutron-spectrum nuclear reactors and for accelerator-driven nuclear systems, in which the LBE can also act as the spallation target. …
