Advanced Reactor Content of Application (ARCAP)

To ensure review readiness to regulate a new generation of advanced reactors, a key element of a flexible regulatory framework is to provide guidance for the development of content of an advanced reactor application.

ARCAP

Background

Purpose Provides a roadmap for developing a tech-inclusive, risk-informed application. Leverages existing guidance or guidance that is under development.

Broad Encompasses industry-led technology-inclusive content of application project (TICAP).

Need for Additional Guidance Roadmap also identifies areas where additional guidance is needed (i.e.: Technical Specifications).

Regulatory Applicability (As applicable) 10 CFR Parts 50, 52, and informs 53.

Streamlined Review Process ARCAP guidance document not intended to replicate NUREG-0800, Standard Review Plan for LWRs.

Previous Discussions ARCAP overview discussed at August 2020, October 2020, and February 2021 public meetings.

TICAP

Background

Purpose

  • TICAP is industry-led guidance focused on describing the scope and level of detail for portions of an application consistent with the LMP.
  • Industry-led TICAP guidance only applicable to portions of first 8 SAR chapters.
  • Aims to minimize burden of generating and supplying non-safety significant information.

Regulatory Applicability (As applicable) 10 CFR Parts 50, 52, and informs 53 Methodology Scope is governed by the LMP-based safety case. LMP process is one approach to select licensing basis events, develop SSC categorization and ensures defense-in-depth is considered

of extensive stakeholder engagement.

  • Consists of 12 main chapters.
  • Provides the most safety-significant information at the forefront (ASC).
  • Focus on the most relevant safety information while removing unnecessary details.
  • Additional information/background is available for audit/inspection by NRC.
  • Contents of application are still under discussion. List represents a draft outline

Note: SAR Chapters 1-8 addressed by TICAP. SAR Chapters 9-12 addressed by ARCAP.

Our Ch. 1- General Plant Information, site description, and overview of safety case (TICAP)

Information should provide an understanding of the overall facility (type of application, the number of plant units, a brief description of the proposed plant location, and the type of advanced reactor being proposed). The site description should provide an overview of the actual physical, environmental and demographic features of a site, and how they relate to the affirmative safety case.

Our Ch. 2- Generic Analyses (TICAP)

Certain analyses are common to several licensing-basis event analyses. Information should describe the process and methods used to develop baseline information related to the probabilistic risk assessment (overview of the PRA), source-term analysis, and design-basis accidents (DBAs) analytical methods.

ARCAP Roadmap ISG - Example 2

Small Modular Reactors and Other New Technologies rulemaking.

  • Rule would amend the NRCs regulations to add new emergency preparedness requirements for small modular reactors, non-light-water reactors and non-power production or utilization facilities.
  • Rule would adopt a scalable plume exposure pathway emergency planning zone approach that is performance-based, consequence-oriented, and technology-inclusive.
  • Contents of application are still under discussion. List represents a draft outline

Our Emergency Preparedness Plan This rulemaking would develop a dose-based, consequence-oriented framework for future SMR applicants and licensees with respect to offsite EP that would reduce the need for exemptions related to regulations associated with large LWRs.

  • Ongoing rulemaking.
  • DG-1357, Emergency Response Planning and Preparedness for Nuclear Power Reactors.

Key Messages Whats Next?

Draft roadmap ISG released as white-paper to solicit stakeholder feedback. Further iterations expected.

Some sections are primarily aligned with the Licensing Modernization Project (LMP), however:

  • the concepts and general information may be used to inform the review of an application submitted using other methodologies (as applicable) such as a maximum hypothetical accident, or deterministic approaches.

Draft ISG expected to be released Fall 2021.
