Copper melting behavior at extreme temperatures could inform fusion materials
Using SLAC’s electron camera, researchers recorded timestamps of solid copper atoms (orange) as they melted (yellow) after being blasted with laser heat. This graphic shows how copper atoms changed over a period of several femtoseconds (millionths of a billionth of a second), notated here as fractions of a picosecond. Instead of the predicted collapse, the researchers saw a gradual melting. (Image: Greg Stewart/SLAC National Accelerator Laboratory)
The SLAC National Accelerator Laboratory has announced researchers have conducted experiments testing how copper melts under extreme conditions, such as those it might be exposed to in a fusion machine. The results, published in Nature Communications, found that a copper thin film was more resilient to melting than models had predicted, uncovering molecular dynamics that had been missing from calculations.
“These results greatly improve the simulations we use to predict which materials have the best shot at surviving the extreme conditions of future fusion reaction chambers,” said Mianzhen Mo, the SLAC staff scientist who led the research.
Educational Session|Panel|Sponsored by Plant Reliability
Tuesday, August 6, 2024|1:30–3:00PM EDT|Banyan 2
Parts quality is foundational to a reliable plant. This was affirmed by INPO IER 21-4 (Improving Plant Reliability) in 2021, which included an action to “establish a sustainable parts quality process.” Despite the industry expectation and importance of establishing and maintaining a robust process, there is no single approach used by utilities to implement a parts quality process.
This session will discuss the many approaches the industry has taken to align with INPO’s IER as well as highlight best practices and lessons learned. Key elements covered in this session include:
• Critical part issues that are affecting safety and reliability today.
• Causes of critical part failures and the importance of accurate causal evaluations and failure analysis.
• Importance of supplier performance program engagement.
• Approaches for (and examples of) implementing the recently published INPO What Excellence Looks Like (WELL) sheet, which was provided to help reduce plant reliability events caused by faulty parts and components.
