| Abstract Scope |
Advanced manufacturing (AM) techniques are currently being explored for nuclear reactor component applications as they can help reduce costs, alleviate supply chain issues, and produce components with complex geometries, enabling more efficient reactor designs with fewer welds. However, defects in AM parts must be examined to determine their impact on component performance and lifetime due to the high-consequence nature of nuclear reactor component failures. This investigation uses micro X-ray computed tomography (XCT) to explore the porosity of a series of directed energy deposition (DED) fabricated stainless steel 316 samples. Fabrication parameters including laser power, powder feed rate, deposition rate, and hatch distance were varied and the resulting porosity density and types were quantified. This presentation concludes with a discussion of the importance of nondestructive examination (NDE) techniques for both post-build quality control and quality assurance, as well as in-service inspection for nuclear reactor components. |
