Abstract
The effects of neutron irradiation on the susceptibility to liquid metal embrittlement of two primary selected materials
for MYRRHA project an accelerator driven system (ADS), was investigated by means of slow strain rate tests (SSRT).
The latter were carried out at 200 C in nitrogen and in liquid Pb–Bi at a strain rate of 5 · 106 s1. The small tensile specimens
were irradiated at the BR-2 reactor in the MISTRAL irradiation rig at 200 C for 3 reactor cycles to reach a dose of
about 1.50 dpa. The SSR tests were carried out under poor and under dissolved oxygen conditions (1.5 · 1012 wt%
dissolved oxygen) which at this temperature will favour formation of iron and chromium oxides. Although both materials
differ in structure (fcc for A316L against bcc for T91), their flow behaviour in contact with liquid lead bismuth eutectic
before and after irradiation is very similar. Under these testing conditions none of them was found susceptible to liquid
metal embrittlement (LME).
