January 11, 2021 MEMORANDUM TO: John P. Segala, Chief Advanced Reactor Policy Branch Division of Advanced Reactors and Non-Power Production and Utilization Facilities Office of Nuclear Reactor Regulation Signed by Sebros FROM: Joseph M.

SUMMARY
OF DECEMBER 10, 2020, PUBLIC MEETING TO DISCUSS TECHNOLOGY INCLUSIVE CONTENT OF APPLICATION PROJECT, ADVANCED REACTOR CONTENT OF APPLICATION PROJECT, AND APPLICABILITY OF REGULATIONS TO NON-LIGHT WATER REACTORS On December 10, 2020, the U.S. Nuclear Regulatory Commission (NRC) staff held a Category 2 public meeting with stakeholders, to discuss the technology inclusive content of application project (TICAP), the advanced reactor content of application project (ARCAP) and applicability of regulations to non-light water reactors (non-LWRs). The meeting notice is available in the NRCs Agencywide Documents Access and Management System (ADAMS) at Accession No. ML20344A139, and the presentation slides are available at ADAMS Accession No. ML20344A057. The Enclosure to this summary provides the attendees for the meeting as captured by Microsoft Teams.
Meeting Highlights Technology Inclusive Content of Application Project and Advanced Reactor Content of Application Project In preparations for the December 10, 2020, public meeting the NRC staff developed the following four documents to support the meeting (the first three documents provided in the list below are publicly available in ADAMS at Accession No. ML20316A013 and the last document is publicly available in ADAMS at Accession No. ML20321A326).
A document titled, Comments on Industry-Developed TICAP Annotated Outline. The purpose of this document was to provide NRC staff comments on the TICAP outline discussed during an October 22, 2020, meeting (available at ADAMS Accession No. ML20294A382).

J Segala 2 A document titled Draft Concept for Updated TICAP-ARCAP Combined Outline. The purpose of this document was to provide initial concepts for how the industry-developed TICAP final safety analysis report (FSAR) outline discussed during an October 22, 2020, meeting (available at ADAMS Accession No. ML20294A382) could be merged with the NRC staff developed ARCAP outline found at ADAMS Accession No. ML20107J565.
The staff developed ARCAP draft Chapter 2, Site Information. This document includes a proposal to limit the amount of material in safety analysis report (SAR) Chapter 2 to that which is necessary for establishing safety significant design parameters and performing the safety analysis, along with its supporting bases.
A document regarding considerations for the expected level of detail in an application that used the licensing modernization project approach.
Regarding industrys TICAP annotated outline and how the industry-developed TICAP annotated outline and NRC staff-developed ARCAP annotated outline could be integrated, the industry and the staff agreed that more dialogue was needed. In general, there was agreement that a different organization of the FSAR portion of an application for an LMP-based approach vice an FSAR organization for a non-LMP based application was appropriate. It was recognized that additional discussion was needed to clearly outline the scope of what guidance will be provided through the TICAP guidance and what guidance will be provided via ARCAP. For example, industry indicated that because validation of analytical codes is not addressed in Nuclear Energy Institute (NEI) 18-04, Revision 1, Risk-Informed Performance-Based Technology Inclusive Guidance for Non-Light Water Reactor Licensing Basis Development, as endorsed by the NRC, industry does not intend to provide detailed guidance on this topic as part of TICAP. The staff indicated this is an area that would be addressed as part of the ARCAP guidance it is developing.
In addition, the staff and industry agreed that additional discussion was needed to develop guidance for the expected level of detail in an application. There was agreement that a graded approach that leads to more information being provided for safety-related structures, systems, and components and less information for non-safety related structures, systems and components (SSCs) with special treatment was appropriate. However, the level of detail for SSCs that serve a defense-in-depth function was recognized as an area that needed additional discussions.
The staff provided an overview of draft ARCAP Chapter 2, Site Information. It was noted that additional discussion is appropriate to determine where this information should be placed in the FSAR since it does not appear as an area in the draft TICAP outline discussed during the meeting.
Industry provided an update on the status of the four tabletops that are scheduled over the next several months including:
TerraPower Molten Chloride Reactor Experiment - a less than 1 Megawatt (MW) thermal pool-type molten salt reactor X-energy Xe-100 - an 80 MW electric pebble bed high temperature gas cooled reactor Westinghouse eVinci - a heat pipe microreactor
J Segala 3 GE-Hitachi Versatile Test Reactor - a 300 MW thermal pool-type sodium-cooled fast reactor Industry took an action to continue to develop the schedules for the four tabletop exercises discussed during the meeting and to keep the NRC staff informed when the dates for NRC observation of the four tabletop exercises are identified.
Applicability of Regulations to Non-Light Water Reactors The purpose of this portion of the meeting was to discuss a document titled, NRC Staff Draft White Paper - Analysis of Applicability of NRC Regulations for Non-Light Water Reactors, dated September 2020, available at ADAMS Accession No. ML20241A017. Prior to the meeting the Nuclear Energy Institute provided a letter dated October 30, 2020, titled NEI Input on Analysis of Applicability of NRC Regulations for Non-Light Water Reactors. NEIs cover letter and associated enclosure are available in ADAMS at Accession No. ML20308A660, and Accession No. ML2030308A559, respectively.
As part of the discussion, NRC staff noted that future interactions would be beneficial in resolving the issues discussed in the slides. The NRC staff stated that the slides reflected a need to provide a durable and clear licensing basis using a decision-making process that was not arbitrary. Industry and NRC staff agreed that the applicability being discussed was on a generic basis, and that clarity in exemption requests would be beneficial for non-LWR applicants. Further, NRC staff pointed out that the industry slides appeared to take out of context the information found in the Staff Requirements Memorandum for SECY-19-0036, Application of the Single Failure Criterion to Nuscale Power LLC's Inadvertent Actuation Block Valves, (ADAMS Accession No. ML19183A408) and Commission Order CLI-20-03, Florida Power & Light Co. (Turkey Point Nuclear Generating Units 3 and 4), (ADAMS Accession No. ML20114E147).
The staff actions from this portion of the meeting included:
Consider revisions to the draft white paper to provide some clarity on the level of detail needed for an application to address the applicability of regulations for non-light water reactors.
Consider providing a template for exemptions for items found in Table 2 of the draft white paper.
Consider discussing at a future stakeholder meeting what the timeline may be for the staff update and next steps to issue a revised white paper.
NEI actions from this portion of the meeting included:
Identify examples of specific regulations where the NRC staff position in the draft white paper is not clear. NEI will identify the regulations that need clarification and in the near term will provide a schedule for this feedback.
