| Abstract Scope |
Components in nuclear reactors experience multiple environmental extremes. In heavy liquid metal (HLM) environments like lead-bismuth eutectic (LBE), liquid metal embrittlement (LME) is the main degradation mechanism. The severity of LME is tied to several factors (alloy composition, grain size, presence/absence of oxide layers) and is expected to be impacted by other extremes present simultaneously.
In this work, we will describe an approach designed to accelerate fundamental research into radiation-corrosion interactions in metals. The Tiny Irradiation-Corrosion Experiment (Tiny-ICE) consists of multiple small corrosion “chambers” filled with HLM. Physical vapor deposition is used to deposit a gradient thin-film across the chambers to allow rapid exploration of a compositional space. We will present preliminary results from corrosion and irradiation-corrosion experiments and discuss how this information can be used to improve our understanding of materials degradation in HLM environments and susceptibility to LME. |
