Flow rate dependent corrosion behavior of Eurofer steel in Pb–15.7Li

Long-term corrosion behavior of martensitic steel welds in static molten Pb–17Li alloy at 550°C

“…[9] protective surface oxide layers inhibit contact between the molten Pb-17Li alloy and the steel matrix, and thus, the oxide surface layers themselves do not suffer from any further direct attack by the Pb-17Li alloy. The surface oxide layers form during the initial corrosion time, called an incubation period, and commonly appeared in the early stage of the liquid Pb-17Li/metal corrosion [18][19][20][21]. However, in this work, a similar oxide layer was found in neither exposure-time samples.…”

TBM testing in ITER: Requirements for the development of predictive tools to describe corrosion-related phenomena in HCLL blankets towards DEMO

“…Corrosion testing in PICOLO [9,10] confirmed for turbulent conditions such empirically set up correlations. Such verification for Eurofer is missing under laminar flow.…”

Conceptual Design of the EU-DEMO Dual Coolant Lithium Lead Equatorial Module

“…The outlet temperature must be as high as possible in order to maximize the thermal efficiency of the power conversion system. However, in the present DCLL version, it is limited to 550°C in order to avoid creep of the structural material (Eurofer) [12] and extreme corrosion rates [13]. Therefore, a very narrow operational window is expected in terms of PbLi temperatures, i.e., 300°C-550°C.…”

“…In addition, the amount of heat extracted by helium can be kept as low as possible since the structure is thermally isolated from the PbLi. One of the major constraints of the sandwich FCI concept is the possible Eurofer corrosion due to PbLi at 550°C [4], [13].…”
