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.
