“…The primary factor limiting the technological viability of the Pb and Pb-Bi eutectic is their corrosive nature towards structural steels. Such coolant has tendency to corrode/dissolute alloying elements from the fuel cladding and structural materials [1,[5][6][7][8][9] within the reactor and causes liquid metal embrittlement (LME) [1,[10][11][12][13][14]. Oxide scales are known to be able to protect the structural alloys against the liquid metal corrosion [1,7].…”

For the safe development of GenIV nuclear reactors, it is necessary to study the compatibility of structural materials with new coolants. Current work describes the behavior of ferriticmartensitic steel T91 in a Heavy Liquid Metal environment. Specimens were pre-stressed up to yield strength and subsequently exposed to the lead-bismuth eutectic (LBE) under static conditions for 2000 hours. The goal was to identify the susceptibility to crack initiation under selected experimental conditions. The examination of metal-LBE interface was done in a reference position of the sample using the SEM equipped with EDX. Formation of oxide scales observed on the interface had no signs of crack initiation. The oxide was characterized by a twolayer structure. A TEM lamella was created from the sample by a FIB in-situ lift-out technique and it was subsequently analyzed in HRTEM. Individual oxide layers were identified and characterized by SAED, EELS and EDS techniques. Finally, STEM-HAADF and EFTEM techniques were used to visualize the matrix-oxide interface.

“…Austenitic steels, for example, suffer from severe dissolution attack at over 500°C [1][2][3]. Ferritic and martensitic steels, on the other hand, form thick oxide scales in similar conditions, restricting them to lower-temperature applications [2,4,5]. Studies have also shown that Al has a beneficial influence on the compatibility of materials in LBE.…”

“…The corrosion rate was normalized to a value of 25 lm after 1 year of exposure in Pb-flow at T = 773 K (500°C). This value was used as a conservative estimation for the effect of protective layers deposited on T91 steel cladding [18,40]. The corrosion model for the cladding inner surface is still under development and not incorporated yet.…”
