SUMMARY

OF THE OCTOBER 24-26, 2023, NRC WORKSHOP ON ADVANCED MANUFACTURING TECHNOLOGIES FOR NUCLEAR APPLICATIONS The U.S. Nuclear Regulatory Commission (NRC) staff from the Office of Nuclear Regulatory Research (RES) and the Office of Nuclear Reactor Regulation (NRR) held a workshop on October 24-26, 2023, on advanced manufacturing technologies (AMTs) for nuclear applications.

The purpose of this workshop was to discuss ongoing activities related to AMTs including nuclear and non-nuclear industry implementation plans, qualification and certification approaches, research, and codes and standards activities.

The public meeting summary, workshop agenda, and list of workshop participants are enclosed.

The workshop presentations are in the Agencywide Documents Access and Management System (ADAMS) under ADAMS package accession number ML23324A231.

U.S. Nuclear Regulatory Commission Public Meeting Summary

Title:

2023 NRC Workshop on Advanced Manufacturing Technologies for Nuclear Applications Meeting Identifier:

20231129 Date of Meeting:

October 24-26, 2023 Location:

NRC One White Flint North, TWFN Auditorium (HQ-TWFN-P2AUD) 11555 Rockville Pike Rockville, MD Type of Meeting:

Information Meeting with Question and Answer Session.

Purpose of the Meeting: The purpose of this workshop was to update the staff and stakeholders on (1) practical experience and plans for implementing advanced manufacturing technology (AMT) for nuclear and non-nuclear components, (2) AMT process/part qualification and certification approaches, including the incorporation of modeling and simulation, and (3) the latest developments in codes and standards pertaining to AMT adoption.

General Details: This workshop was conducted as a hybrid meeting over three days with about 50 in-person attendees and approximately 340 online attendees representing domestic and international research, academic, industry, and regulatory organizations. The workshop was organized into four sessions, which were chaired by NRC staff members:

Session 1: Implementation of AMTs in Nuclear and Non-Nuclear Applications Session 2: Qualification and Certification Session 3: Performance Characteristics Session 4: Code and Standards Session Summaries:

Session 1:

Presentations were given by NRC, Rolls Royce, Sheffield Forgemasters, U.S. Navy, Argonne National Laboratory (ANL), Oak Ridge National Laboratory (ORNL), Nuclear Energy Institute (NEI), Electric Power Research Institute (EPRI), Framatome, Lincoln Electric, Siemens Energy, and Westinghouse.

The topics presented included experience with implementing powder metallurgy with hot isostatic pressing (PM-HIP) to manufacture nuclear components, implementing AMTs in the U.S. Navy fleet, electron beam welding, AMTs for nuclear fuel components, AMTs role in making spare parts on demand, AMTs role in the nuclear energy sector, and plans to develop a framework for qualifying AMT components and to conduct demonstrations for inserting AMT components in nuclear applications.

Session 2:

Presentations were given by Pacific Northwest National Laboratory (PNNL), National Institute of Standards and Technology (NIST), ORNL, Siemens Energy, Barnes Global, Battelle, American Bureau of Shipbuilding, ANL, Pratt & Whitney, and the University of Texas San Antonio.

The topics presented included qualification and certification approaches for materials, processes, and equipment, accelerated qualification, and modeling and simulation.

Rapid high throughput testing and NDE were also covered.

Session 3:

Presentations were given by Naval Nuclear Laboratory, ANL, Materials Testing Institute (U. of Stuttgart), Idaho National Laboratory (INL), and Rolls Royce.

The topics presented included testing approaches and results for PM-HIP nickel-base alloys, laser power bed fusion (LPBF) of 316L stainless steel for high temperature applications, irradiation and corrosion testing of LPBF-manufactured materials, performance of LPBF 316L stainless steel in light water reactor relevant environments, data generation and fatigue design curve development for LBPF 316LN stainless steel, and an overview of a new project to perform a critical assessment of the safety of AMTs for international SMR concepts.

Session 4:

Presentations were given by ASTM International, America Makes and GBR Consulting.

The topics covered included overviews of activities related to the challenges and opportunities associated with additive manufacturing materials data, the current state of additively manufactured nickel-based super alloys and a future look at AMTs within the casting and forging industries, and ASME criteria for additive manufacturing.

Key Takeaways:

Session 1:

Several sectors are implementing AMT components to meet the needs of their stakeholders/customers, which satisfies a business case:

Improve parts availability to improve readiness Broaden the supply chain Manage component obsolescence Optimize cost and performance Initial applications have been low risk to gather manufacturing and operating experience.

Safety-significant applications are proceeding cautiously.

It is important for designers to be proactive and intimately involved with fabrication process, especially as safety-significance increases.

Significant opportunities exist for supporting both existing and future platforms.

Session 2:

Multiple qualification pathways:

Traditional testing based Traditional coupled with better process controls and monitoring

S. Ruffin 4

Accelerated, with modeling and simulation (M&S) support (integrated computational materials engineering (ICME))

Initial qualification and certification (Q&C) is largely following the traditional path used for conventional materials for adoption with Codes (e.g., ASME), material property databases (e.g., MMPDS) and applications (e.g., first article testing).

M&S provides the opportunity to both identify critical tests for optimizing/demonstrating additive manufacturing (AM) systems while simultaneously accelerating Q&C:

Building trust in M&S approaches is needed to fully realize their benefits There may be opportunities to leverage Q&C efforts developed (or being developed) within other industries.

Session 3:

Many studies are focusing on understanding and optimizing as-built performance to maximum AM value:

Anisotropy considerations are a stronger consideration within this approach Build variability needs to be addressed at the outset and identifying critical process variables is essential to assessing differences among machines and operators.

Relevant performance metrics can be equivalent or better than conventional wrought materials:

Important to understand and address causal factors for differences M&S provides a needed tool to most efficiently understand environmental effects.

Session 4:

Many standards already exist that support AM Qualification:

Powder quality and handling Heat treatment Testing and characterization Post-fabrication inspection Augmented or new standards are needed to provide overall quality assurance:

Identification and control of essential process variables Implementation of in-process monitoring Incentivize knowledge and data sharing among practitioners.

Codification processes are incorporating AM but processes are lengthy by design and due to uncertainties:

Integrated design, surveillance, and inspection strategies, coupled with targeted key testing can be used to more quickly implement AM systems
