10 Organizational Changes Resulting in Efficient Reviews Core and Interdisciplinary Review Reduction from 6 to 4 Review Phases Teams 6 4 Streamlined safety Focus on More Risk Consolidated two evaluations to Core ACRS reviews into and Safety produce fewer one phase Teams Significant Design interim documents Aspects

11 Organizational Changes Resulting in Efficient Reviews

• Effectively allocate resources based on risk and safety Recognizing our focus significance

• Monitor Performance on safety:

Allows for changes in schedules and budget

• Allows for quick Contributes to assessment of openness with project execution, schedule, and applicant and public budget

NRC Is Realizing Its Vision and Strategy 17 for Non-Light Water Reactors Computer Codes & Review Tools Flexible Review Process Knowledge, Skills, and Capabilities Policy and Technical Issues Consensus Codes and Standards Communication

New and Enhanced Guidance Is 18 Enabling High Quality Applications Licensing Basis

• RG 1.233 on the Licensing Modernization Project Regulatory Applicability

• RG 1.232 on Principal Design

• Draft white paper:

Criteria Applicability of NRC Regulations for Non-Light Content of Application Water Reactors

• Advanced Reactor Content of Application (ARCAP)

• NUREG-1537 updates for Consensus Codes and molten salt non-power reactors Standards

• DNRL-ISG-2022-01 for LWR

• Trial RG 1.247 on the non-construction permits LWR PRA standard

• Draft RG 1380 and Fuel Qualification NUREG-2245 on ASME Section III Division 5

• NUREG-2246

Regulatory Infrastructure Is Supporting 19 Early Movers Safety and environmental reviews on track

• Pre-application engagement resolution of key technical issues 0

• Use of audits timely application updates and limited RAIs

• Early and productive ACRS engagements Application is accepted and under review

• Pre-application engagement early identification of key technical issues and 0 information needs

• Pre-application audits forum to discuss attributes of a high-quality application needed to establish an aggressive review schedule

Staff Are Managing and Overcoming 20 Challenges Wide Variety of Designs

• Staff training and development

• Knowledge sharing across core teams

• Working with partner offices

• Contract support Schedule Uncertainty

• Pre-application engagement Novel Regulatory

• Regulatory engagement Infrastruture plans

• Readiness reviews

• Flexible staff

• Leveraging related guidance

• Knowledge management and lessons-learned
