S. Frankl, et al.
Session 2:
Presentations were given by the Nuclear Energy Institute, Electric Power Research Institute (EPRI), Exelon, Westinghouse, Framatome, and Pacific Northwest National Lab (PNNL).
The topics that were presented include identification of candidate components and uses of AMT, AMT parts in service or soon to be in service, uses of AMTs in fuel hardware components, and AMT development and qualification process.

The topics that were presented include implementation and justification strategies for identifying and implementing candidate nuclear applications, effects of processing and post-processing variables on performance/qualification, regulatory assessment activities and approval processes, developing PM-HIP and electron beam welding (EBW) for thick section ferritic components, evaluating performance of cold spray both with and without laser glazing, past and future cold spray applications, and cold spray field implementation.
Session 4:
Presentations were given by Westinghouse, EPRI, NNL, Federal Aviation Administration (FAA), Oak Ridge National Lab (ORNL), and PNNL.
The topics that were presented include implementation process of the AM thimble plugging device and advanced debris filtering bottom nozzle, progress on the American Society of Mechanical Engineers (ASME) code case and data package for 316L laser powder bed fusion, inservice inspection, and accelerating quality certification of critical components with AM.
Session 5:
Presentations were given by America Makes, National Institute of Standards and Technology (NIST), Savannah River National Lab, General Electric, EPRI, ASTM International, NASA, and NNL.
The topics that were presented include development of consensus standards to enhance readiness of AMTs through roadmaps and centers of excellence, development of nuclear and non-nuclear standards, and the industry and regulatory needs that are driving the development.
Session 6:
Presentations were given by the NRC, the Finnish Radiation and Nuclear Safety Authority (STUK), FDA, and FAA.
The topics that were presented include the approaches for regulating AMTs from nuclear and non-nuclear regulators.
Session 7:
Presentations were given by VTT, ORNL, Idaho National Lab, ANL, University of Wisconsin, NIST, and EWI.
S. Frankl, et al.
The topics that were presented include worldwide efforts from researchers on solutions to quality assurance and quality control issues, role of modeling and simulation in accelerating the qualification of new AMT materials, investigation of cold spray as a corrosion mitigation strategy, advances in in-situ monitoring, and an overview of the Advanced Manufacturing Consortium and its role in coordinating and funding AM research.
Key Takeaways:
Session 1:
Experience with AM components in low or non-safety significant nuclear and non-nuclear applications is being generated and growing.
Use of PM-HIP with EBW for larger nuclear components looks promising, but requires larger HIP and EBW fabrication capabilities.
Cold spray is being used increasingly for Army applications, particularly for high wear applications.
Session 2:
AMT technologies evolve quickly, outpacing the qualification and licensing process.
More collaboration would be beneficial for industry, Department of Energy (DOE),
national labs and NRC.
Operating experience should be utilized from other industries.
Session 3:
Applications should be targeted to optimize unique AM characteristics.
Current analysis tools and the digital nature of AM allows deeper understanding of causal effects.
Regulatory authorities are exploring strategies to support accelerated safe deployment of AM components.
PM-HIP and EBW offer possibilities for large-scale nuclear applications but are currently limited by its current capabilities.
High velocity CS can provide several options for component surface treatment including SCC mitigation, hard-facing, or component repair.
Strategies have been developed to achieve field application of CS for components and structures with limited accessibility.
Session 4:
AMTs are being incorporated with more implementation planned.
Codes and standards development should aim to keep pace with AMT advances.
Much work remains for inservice inspection, including the Performance Demonstration Initiative.
Session 5:
Many gaps exist in technology and standards development. The American National Standards Institute is tracking these gaps (www.ansi.org/amsc).
Standards development organizations benefits from continual communication to reduce redundant standards development.
S. Frankl, et al.
Collaboration with regulatory agencies would be helpful to identify codes and standards needs.
Session 6:
The regulators share many common bases, including performance-based regulation.
The regulators share common technical concerns for AM, e.g., powder characteristics, use of witness coupon testing to represent manufactured parts.
Regulators could consider greater coordination and information exchange, particularly on AM, which is being implemented in many industries now for the first time.
Session 7:
Over the next several years, there will be significant strides in nuclear-focused AM research.
Accelerated qualification of new AM materials is an area of interest to the community.
Next Steps:
Session 1:
As additional experience on implementing AMTs accrues, those lessons learned and data should be used to justify and increase confidence in further applications of AMTs.
AMTs used in other industries or applications may offer benefit to the development and use in nuclear applications.
Session 2:
Continue to develop standards and increase collaboration between all nuclear stakeholders as well as other industries.
Focus collaboration to increase knowledge and confidence in industry for AMTs.
Share lessons-learned from experience with AMTs.
Seek input and feedback from non-nuclear regulators and industry organizations.
Consider performing shorter (i.e., 1-day) workshops on specific AMTs.
Session 3:
Identify strategies to effectively collaborate and rapidly incorporate lessons-learned in standards and guidance.
Expand technical basis to move beyond substitutive applications.
Support intelligent, performance-based qualification framework.
Continue developing technical basis for utilizing these technologies in nuclear applications.
Identify opportunities where these technologies can simultaneously improve component performance (and safety) while reducing lifecycle asset management costs.
Consider methods and applications where AMTs can be combined to optimize performance and increase design flexibility.
Session 4:
Codes and Standards development to expand and continue to mature.
Session 5:
NRC to initiate communication with other regulatory bodies on AMT topics.
Encourage involvement in standards development.
S. Frankl, et al.
Encourage communication between SDOs on AMT standards development.
Session 6:
NRC to consider enhanced coordination with other U.S. regulators to benefit from lessons-learned on approaches for integrating AMTs into current regulatory frameworks.
Coordination among international nuclear regulators can provide broader perspectives and could ensure common approaches, consistent with different national regulatory needs.
Session 7:
Continue to evaluate research needs and technology gaps.
