10 Opportunities for Public Involvement in the 10 CFR Part 52 Design Certification Process
11 Opportunities for Public Involvement in the 10 CFR Part 52 COL Process
12 Relationship Among Combined Licenses, Early Site Permits, and Standard Design Certifications
13 P re -Application Activities Supporting the Licensing Process
- P re-application engagement (ML21145A106)
- NRC response to applicant s general correspondence
- NRC review of and feedback on applicant s regulatory engagement plan (ML18122A293)
- NRC assessment and response to applicant s white papers
- NRC evaluation of applicant s technical and topical reports
- P re-application audits to support a high-quality application.
14 P re-application Engagement (ML21145A106)
15 Best Practices
- Conducting face-to-face page-turn activity with applicable technical staff
- Issuing regulatory gap analysis letters to identify unique areas of designs
- Reviewing consensus codes and standards, and incorporating it into staff guidance
- Reviewing other supporting documents or programs
- Conducting rulemaking and developing or updating guidance
16 Activities Supporting An Efficient Review
- Submission of a high-quality application
- Use of a risk-informed approach to focus staff resources on review areas commensurate with their safety significance
- Complete and timely submission of responses to requests for additional information
- Use of a tracking process for the highly challenging issues (HCIs)
- Early coordination with technical, management, and legal staff on HCIs
- Use of audits in areas involving first-of -a -kind design features and to support resolution of RAIs and HCIs
- Use of an electronic reading room to share information where the design is evolving
- Use of a core review team and charter to facilitate efficient reviews.
17 Review and Assessment of White Papers
An applicant may submit a white paper to the NRC seeking informal feedback and can allow the preliminary design review to be focused on the technical issues related to the safety of the design.
The NRC s response does not constitute an agency position or provide any finality or backfit protection.
The objective of a white paper is to increase applicant s understanding,
to explore problems, or address how to make a design specific decision.
There are no specific requirements or guidance for the development, or the NRC staff review of white papers.
18 Benefits arising from applicant s white papers
- Preliminary regulatory feedback in response to applicant requests. Examples include:
- licensing approaches
- proposed format and outline of an application
- applicability of regulations to a design
- applicable consensus codes and standards
- qualification strategies, methodologies, testing plans
- proposed principal design criteria, postulated initiating events, SSC classification
- staffing approaches, EPZ sizing, transportation and packaging
- NRC staff gains knowledge of a design and possible license approaches by an applicant
19 Relationship between white papers and a future license application
- Discussed in the applicant s regulatory engagement plan
- Feedback used by applicant to develop its application
- Dependent on topic of white paper
- Supports the applicant s abilities to assess alternatives and to further progress its design
- Supports the staff s review prioritization that could affect expected regulatory outcomes
- Less specificity and less regulatory certainty than topical reports
20 Review and evaluation of topical reports An applicant may submit a topical report for review and approval that contains technical information about:
- A re a c to r
- Structures, systems and components
- A safety topic
- A methodology Non-LWR applicants commonly submit topical reports on the applicability of regulations and principal design criteria.
A topical report may reference technical reports that provide results of research, testing, or analyses to help verify or validate computer models, or other supporting information for a license application.
Guidance on the NRC staff s review of topical reports is found in NRR Office Instruction LIC-500, Topical Report Process
21 Benefits arising from topical report reviews
- Early review and feedback of technical information by ACRS
- Improves efficiency of licensing process by allowing NRC staff review of methodologies, designs, and operational requirements subsequently referenced in a license application
- Facilitates regulatory certainty on key methodologies, designs, and operational requirements subsequently referenced in a license application
- Early identification of potential policy issues
- May provide a technical basis for a licensing action
- Used extensively for obtaining NRC staff findings on proposed design features and analysis methods.
22 Relationship between topical reports and a future license application
- Discussed in the applicant s regulatory engagement plan
- Staff findings expected to be referenced in a license application
- Conditional staff findings expected to be addressed and reviewed in a license application
- More specificity and more regulatory certainty than white papers
23 Staff Review Process Enhancements
- Developing and Completed Review Guidance
- Lig ht-water Power-Reactor Construction Permit Interim Staff Guidance (ML21165A157)
- NuScale lessons learned Report (to be issued early 2022)
- Contents of Applications TICAP/ARCAP
- Updated NRC Staff Draft White Paper Analysis of Applicability of NRC Regulations for Non-Light Water Reactors (ML21175A287)
- Interim Staff Guidance, COL-ISG-029. Environmental Considerations Associated with Micro-reactors (ML20252A076)
- RG 1.232 Advanced Non-LWR Reactor Design Criteria (ML17325A611)
- RG 1.233 Licensing Modernization Project/NEI 18- 04 (ML20091L698)
24 Staff Review Process Enhancements (continued)
- Continuing to streamline the safety evaluation reports
- Removing history of responses to requests for additional information
- Improving quality and readability of the SER
- Establishing writing standards for sections in the SER using plain language and focusing on the information necessary to communicate the bases for NRC staff decisions
- Implementing a Flexible Review Process
- Supports the NEIMA generic milestone schedules
- Advisory Committee on Reactor Safeguards briefings planned early to support a focus on specific technical areas.
25 Comparison DANU proposal aligns with the 4 Phase Schedule because the SER with Open Items and ACRS of Review of the SER with Open items are eliminated Approaches from the schedules. A comparison of this is shown in the table below:
