2018 NRC Standards ForumSeptember 11, 2018Jason ChristensenMaterials Engineer, Corrosion

& Metallurgy BranchAmy HullSr. Materials Engineer, Corrosion and Metallurgy BranchOffice of Nuclear Regulatory Research, Division ofEngineeringReview of Advanced Manufacturing Outline 1.Background 2.Developing an understanding of AM 3.Engagement with industry partners 4.Action plan for advanced manufacturing (AM)5.Codes and standards collaboration 6.Regulatory updates 7.Questions Why would AM be of Interest to the Nuclear Industry

?*Produce replacement parts for the existing fleet with a very short turnaround-Obsolete parts:some units are over 40 yearsold*Produce new or complex parts for the new fleetof ALWRs, SMRs and Gen IVapplications

• Design to include improved flow characteristics or special features that can't be achieved through casting/forging/machining*Introduce favorable properties via unique microstructures

• Design forperformance

• Speed of delivery

• Cost reductionsWolbert , 2018 Developing an understanding of AM*Research requests from the Office of Nuclear Reactor Regulation (NRR) and the Office of New Reactors (NRO)

• NRC is developing an action plan which will include research of AM techniques

• RES is looking to leverage the existing research and capabilities of DOE labs.

• Understanding of:

• Repeatability and control of AMprocesses*Quality and inspectability of AM-madeparts*Service performance, degradation mechanisms, and aging of AM-madeparts

• NRC hosted a public workshop"Additive Manufacturing for Reactor Materials and Components"

• Standardizationactivities

• Research and applicationsin nuclear and otherindustry*Processes andcapabilities

• Technical and regulatorychallenges

• Developed NUREG/CP

-0310 "Proceedings of the Public Meeting on Additive Manufacturing for Reactor Materials and Components"

• Developing an addendum to the EPRI MOU to allow for regular knowledge sharing

• Leveraging the capabilities and research being performed by the Department of Energy

• Participation in numerous conferences such as the NRC Vendor Forum, QNDE, and FAA

-EASA Joint WorkshopEngagement with Industry Partners and other Regulatory Agencies EDO Innovation and Transformation Initiative

• Innovation and Transformation at the NRC was the subject of a new initiative in 2018.

• Taking a more proactive posture for emerging technologies was reflected in SECY 0060 issued on May 23, 2018, by the EDO to the NRC Commissioners. (publicly available at ML18110A186)

• "New materials and manufacturing approaches" are identified in the context of emerging novel technologies

• The NRC staff is pursuing early engagement with ongoing industry research into advanced manufacturing methods, such as additive manufacturing (AM).

• Meanwhile, industry is planning to gain operating experience by initiating the use of AM in 2018 to fabricate components with low safety significance. The combination of building operating experience through limited low safety significance implementation and NRC engagement in research and codes and standards development is an ideal approach to ensuring the safe and secure use of new materials, which can provide the basis for future NRC approval in a broader range of applications.

• The NRC is currently developing an advanced manufacturing action plan that will address appropriate guidance updates and other activities.

• To address NRC readiness for regulatory review of AM-madeparts, in order to license their use in safety-related systems in nuclearapplications

• To provide for interoffice coordination

-reactors, waste management,research*To continue engagement with codes and standardsorganizations

• A subject of NRC "Innovation and Transformation"initiative

• In early stages ofdevelopmentOneperspective-NRC Action Plan for AM Codes and Standards Collaboration

• NRC is collaborating with codes and standards bodies as they work to develop standards for the use of AM

-made components in the nuclear industry

• ASME Special Committee on use of Additive Manufacturing for Pressure Equipment

• Next meeting: November 11

-16, 2018 in Atlanta, GA

• ASTM E08, E07, and F42 committees

• Next meeting: November 2018 in Washington D.C.

NRC Interests

• Schedule and method for industry implementation

• Licensing Topical Report process

• License amendment process

• 10 CFR 50.59 process

• Timing of plant

-specific implementation vis

--vis codes/standards action and/or topical report approval will significantly affect review complexity

• Volume of licensing actions

• Could lead to prioritization of reviews Path Forward for the NRC

• Develop an understanding of AM

• Continue collaboration with industry partners and DOE

• Continue participation in codes and standards activities

• Develop an action plan for AM Questions?
