MEACTOS - Mitigation of EAC Through the Optimisation of Surface Condition

Popis výsledku v původním jazyce

Component manufacturing processes, particularly the final machining or grinding operations, can impact the long-term environmentally-assisted cracking (EAC) susceptibility of materials in light water reactor environments. Long-term management of EAC requires an improved understanding of the crack initiation processes, with particular emphasis on the influence of the as-manufactured component surfaces on the development and coalescence of small cracks. A new international collaborative program, MEACTOS – Mitigation of EAC through the Optimization of Surface Condition, has been initiated under the sponsorship of Horizon 2020 to address this matter and thereby improve the safety and reliability of Generation II and III/III+ nuclear power plants. The MEACTOS program builds upon the results of several NUGENIA+ projects dealing with EAC (MICRIN+, ASATAR) and machining processes (McSCAMP). This 4-year research project encompasses the assesment of the environmental cracking performance of austenitic stainless steel and FM 182 welds as a function of optimized machining and surface treatments. The effect of the machining and surface treatments on local microstructural development will be assessed, and EAC initiation data will be correlated in order to develop models for improved prediction of material performance. Presented at Fontevraud9 conference (Contribution of Materials Investigations and Operating Experience to Light Water NPPs’ Safety, Performance and Reliability), 17.-20.9.2018, Avignon, France.
