L. Lund The discussions were valuable to understanding areas for further collaboration across SDOs and how the NRC and stakeholder groups can be more effective in developing, updating, and meeting the codes and standards needs. The following is a summary of the discussions in the sessions.
Session 1: Overview of Recent Codes and Standards Initiatives Session 1 was moderated by Ronaldo Jenkins, Senior Project Manager in RES, Division of Engineering (DE). The session included five presentations as follows:
- 1. ANS/ASME Nuclear Standards Collaborative to Support Advanced Reactor Standards Needs (Donald Eggett, ANS and Thomas Vogan, ASME)
- 2. Recent NEI Codes and Standards Initiatives for Advanced Reactors (Mark Richter, NEI)
- 3. NEI Codes and Standards Task Force Initiatives (Thomas Basso, NEI)
- 4. Rulemaking Plan on Revision of Inservice Testing and Inservice Inspection Program Update Frequencies Required in 10 CFR 50.55a (David Rudland, NRC)
- 5. Regulatory Guidance Framework for IEEE Electrical Standards (Sheila Ray, NRC)
The session opened with a presentation and discussion on the ANS/ASME Nuclear Standards Collaborative. This is a centralized industry led team aimed at coordinating and collaborating with SDOs to support the reactor designers, regulators, and other interested stakeholders in the development of industry standards and/or guidelines for advanced reactor designs. Near term milestones include, in part, developing a roadmap and prioritized list of the next needed advanced reactors standards, and developing proposals for funding and resource development for the next highest priority standards. This presentation was followed by two presentations by NEI, the first one on NEIs participation and perspectives on efforts related to advanced reactor standards and the second one on an update of NEIs Codes and Standards Task Force activities including activities related to ASME Boiler and Pressure Vessel (BPV) Code Section III,Section XI, and the Operation and Maintenance (O&M) Code. These presentations were followed by an NRC staff presentation on the status of SECY-21-0029 which, in part, requests Commission approval to initiate a rulemaking to amend 10 CFR Part 50.55a to extend the interval of inservice testing (IST) and inservice inspection (ISI) program updates from 120 months to 240 months. The session ended with a second presentation by NRC staff that discussed updates to the regulatory framework for the endorsement of IEEE electrical standards.
Session 2: Recent Developments in Codes and Standards for New and Advanced Reactors Session 2 was moderated by Alexander Chereskin, Materials Engineer in NRR, Division of Advanced Reactors and Non-Power Production and Utilization Facilities. The session included seven presentations as follows:
- 1. Qualification of High Temperature Materials and their Incorporation into ASME Section III, Division 5 (Sam Sham, INL and Richard Wright, Structural Alloys LLC)
- 2. ASME Code Case: Steel Plate Composite Containment Vessel (SCCV) (Amit Varma, Purdue University)
- 3. OM-2 Inservice Testing for Gen-4 and Beyond (Augi Cardillo and Tom Ruggiero, ASME)
- 5. ASCE 1, 4, and 43 Risk-informed, Performance-based Standards (Andrew Whittaker)
L. Lund 6. Plan for Regulatory Guides on ASCE Standards 1, 4, and 43 for Risk-Informed Applications (Jim Xu, NRC)
This session opened with a presentation on high temperature materials for advanced reactors.
The presentation provided a discussion on aspects related to ASME Section III, Division 5 rules and discussed pathways to increase the availability of high temperature alloys for advanced reactors. This presentation was followed by a presentation on ASMEs Code Case for steel-plate composite (SC) containment vessel construction. This presentation included a description of the SC technology, its performance, example implementation cases, and motivation for its use, including the potential for reducing construction schedules, among others.
The presentation also described the overall structure for the Code Case and highlighted some of the design parameters. This presentation was followed by a presentation on the plans for the development of a new ASME O&M Code. The presentation described the scope of the existing O&M Code and its applicability to light water reactors. The presentation stated that the current O&M Code does not currently include consideration of Small Modular Reactors. The intended applicability of the new O&M Code is any plant/technology. The fourth presentation provided updates on ongoing EPRI research projects including (1) exploring the behavior of large high strength rebar (lap splices and mechanical couplers), (2) best practices for self-consolidating concrete (SCC) for mass concrete structures including alternatives for lowering the heat rise in SCC mixtures, and (3) evaluation of concrete strength at elevated temperatures (i.e.,
temperatures above the temperature limits in ACI 349). The fifth and sixth presentations addressed updates on ASCE 1, 4, and 43 standards and NRC plans for their endorsement, respectively. The presentation on ASCE 1, 4, and 43 included discussions on achieving limit states other than limit state D (i.e., limit state for large light water reactors), seismic isolation provisions in ASCE 4 and 43, and planned developments, among others. The associated NRC presentation provided the anticipated timeframe for issuance of draft guides endorsing these ASCE standards. The session ended with a presentation on ACI 349 updates. The presentation discussed the ongoing and planned activities for ACI 349 and identified topics in ACI 349 and other related standards that could benefit from additional coordination across multiple SDOs.
Session 3: Advanced Manufacturing Session 3 was moderated by Matthew Hiser, Materials Engineer in RES/DE. The session included four presentations as follows:
- 1. NRC Regulatory Approach for Advanced Manufacturing Technologies (Robert Davis, NRC)
- 3. ASME Section III, SubGroup - MF&E. Materials, Fabrication and Examination, TG-AM Task Group Advanced Manufacturing (Daniel Mann, ASME)
- 4. ASME Criteria for Powder Bed Fusion Additive Manufacturing (George Rawls, SRNL and David Gandy, EPRI)
This session opened with a presentation on NRCs regulatory approach for advanced manufacturing technologies (AMTs). The presentation provided an overview and status on NRCs AMT Action Plan, AMT guidelines development, and alternative regulatory pathways for the implementation of an AMT, among others. This presentation was followed by a
L. Lund presentation on EPRIs Advance Manufacturing Methods (AMM) roadmap. The presentation described the consideration of three roadmaps for (1) primary pressure boundary (Class 1) components, (2) reactor internals, and (3) other components (e.g., obsolete parts, classes 2 &3, etc.). The third presentation provided a discussion on ongoing activities under ASMEs Subgroup, Materials, Fabrication and Examination, Task group on Advanced Manufacturing.
The goal of the task group is to write code rules for the adoption of advanced manufacturing processes by Section III, Division 1, and their incorporation into the 2023 and future Editions of ASME Code Section III. The task group plans on addressing the Powdered Metal/Hot Isostatic Pressing (PM/HIP) and Direct Energy Deposition Gas Metal Arc Additive Manufacturing (DED-GMAAM) methods in the 2023 Edition of the Code and the Laser Powdered Bed Fusion (LPBF) method in the 2025 Edition. The session ended with a presentation that provided an overview of ASME PTB 2021 Criteria for Pressure Retaining Metallic components using Additive Manufacturing. The overview focused on the criteria for powder bed fusion additive manufacturing and discussed the criteria covered in the document with respect to scope, highlighted the scope, materials, thermal treatment, design, additive manufacturing procedure and its qualification, qualification testing of additive manufactured components, and production builds, among others. PTB-13 is anticipated to serve as the baseline for future development of ASME additive manufacturing (AM) powdered bed fusion (PBF) Code Cases and Standards development (a Code Case for Section III is being developed for 316 L material using the AM PBF Process).
The 2021 Standards Forum ended with closing remarks by Louise Lund, NRC Standards Executive. The Forum facilitated the sharing of information and perspectives with ongoing standards related efforts as well as needs for further standards development and updates.
Specific areas undergoing revisions and updates across multiple standards were highlighted as well as pathways for incorporation of new materials, methods, and technologies into multiple standards. The discussions also covered ongoing research that is anticipated to inform future standards updates and identified opportunities and areas for further coordination and collaboration across SDOs. Further, the discussions covered NRC efforts to streamline the endorsement of standards in NRC Regulations and Regulatory Guides. The discussions during the Forum are expected to lead to standards with wide ranging support that are more easily utilized by the NRC and licensees.
It is anticipated that the next NRC Standards Forum will be scheduled for Fall 2022.
