Steels were developed for fast breeder reactors (high-temperature strength and swelling resistance under irradiation). In this study the effect of liquid lead on the crack growth rate of the steels was evaluated. Steels T91, MA957, PM2000 were used to evaluate their interaction with liquid lead under stress corresponding to maximum requested design condition. Liquid Metal Embrittlement (LME) initiation tests were conducted on pre-loaded specimens in flowing liquid metal loops. The experiments were carried out at 400°C and post-test evaluation was performed. Some specimens were pre-treated with a chemical flux, to induce wetting of Pb on the steel; some were polished or ground. Liquid Metal Embrittlement was not observed on the surface of any of the pre-loaded specimens after the exposure in liquid lead at 400°C for 500 hours. The results are discussed and compared with previous accelerated tests. Workplace Institute of Physics of Materials Contact Yvonna Šrámková, sramkova@ipm.cz, Tel.: 532 290 485 Year of Publishing 2017
