Draft White Paper -

Preapplication Engagement to Optimize Advanced Reactors Application Reviews (ADAMS Accession No. ML21145A106)

• Provides information to advanced reactor developers on the benefits of robust preapplication engagement in order to optimize application reviews.

Purpose

• Encourages pre-application interactions with advanced reactor developers to provide stability and predictability in the licensing process through early identification and resolution of technical and policy issues that would affect licensing.

• Proposes a set of pre-application activities that, if fully executed, will enable staff to offer more predictable and shorter schedules and other benefits during the review of an advanced reactor license application.

7

• Enhanced regulatory predictability

• Greater review efficiency

• More visibility for public on key topics Benefits of

• Early engagement and interactions with ACRS Pre-Application and other agencies

• Streamlined acceptance reviews Engagement

• Shorter full review schedules than the generic schedules

• Key Assumptions for shortened schedule Timely Responses to Requests for Additional Information (RAIs)

No Substantive Changes to Application No Significant Design Changes (Pre-application vs Application) 8

• NRC staff applied a graded approach to identify key safety and environmental Pre-Application licensing areas for pre-application engagement with advanced reactor Engagement developers Topical Reports - definitive findings White Papers, Audits and Meetings -

feedback and staff awareness 9

• Principal Design Criteria for non-light water reactors

• Process for selection of licensing basis events and classification and treatment of structures, Topical Reports systems, and components

• Fuel qualification plan and associated methodologies

• Source term methodology

• Quality Assurance Program description

• Plan for protection of safeguards information

• Safety and accident analysis methodologies 10

• Probabilistic risk assessment

• Regulatory Gap Analysis Meetings,

• Policy Issues Audits and

• Consensus codes and standards and code cases

• Environmental Activities White Papers - Unique or Novel Methodologies and Issues

- Alternatives to the Proposed Project

- Cooling Water Availability

- Status of Permits and Authorizations

- Meetings on critical components of environmental reviews identified in the white paper 11

• Applicant should allow staff to conduct a pre-application readiness assessment Pre-Application - See Office Instruction LIC-116, Pre-Application Readiness Assessment, ADAMS Accession No.

Readiness ML20104B698)

• Six months prior to submittal date Assessment

• Applicant should provide most current draft of safety analysis report and environmental report, referenced documentation, and applicant staff and contractors

• Right-sized scope based on type of application and extent of pre-application activities leading up to this point 12

UNPL/UAL Collaboration

UNPL/UAL

• Support efficient review of licensing Collaboration submittals for Advanced

• Leverage Advanced Reactor Licensing Branch (UAL) experience with licensing Non-Power reviews involving novel reactor designs Reactor

• Leverage Non-Power Production and Utilization Facility Licensing Branch (UNPL)

Reviews experience with non-power reactor licensing, and associated regulations, guidance, and precedents 14

UNPL/UAL

• Project Managers (PMs) from both UAL and UNPL are assigned for each advanced non-power reactor Collaboration applicant or prospective applicant, as appropriate for Advanced

• UAL PM: Primary contact, and primary Project Non-Power Management responsibility for each applicant or prospective applicant Reactor Reviews

• UNPL PM: Primary UNPL resource for each applicant or prospective applicant, to provide expertise and ensure consistency with non-power reactor guidance (e.g., NUREG-1537) and precedents 15
