NRCS REGULATORY FRAMEWORK FOR DRY CASK STORAGE AND TRANSPORTATION OF SPENT NUCLEAR FUEL AND RELATED RESEARCH ACTIVITIES Commission Meeting February 11, 2021

Opening Remarks Margaret Doane Executive Director for Operations

Overview of Current Dry Cask Storage and Transportation of Spent Nuclear Fuel Environment Robert Lewis Deputy Director Of ce of Nuclear Material Safety and Safeguards

Review and certify packages for Assuring Safety transportation of nuclear materials through a Robust and License spent fuel storage facilities and certify storage casks Comprehensive Program Develop and maintain the inspection program for both transportation and storage

Licensed and Operating Independent Spent Fuel Storage Installations

• Facility licensed only, never built or operated.

Overview of NRC's Regulatory Program for Dry Cask Storage and Transportation of Spent Nuclear Fuel Christopher Regan Deputy Director Division of Fuel Management Of ce of Nuclear Material Safety and Safeguards

Robust Regulatory Framework Strong Tenet of Regulations, Licensing, Oversight Licensing Oversight Comprehensive, performance based and risk Observe critical activities, respond to events, and take informed regulations enforcement where necessary Ensure safety based on data driven decision Periodic inspections at all stages of the fabrication, making in all technical areas design and use of casks Enhancements to focus on areas most important to safety RESULT: SAFE STORAGE AND TRANSPORT OF SPENT NUCLEAR FUEL FOR OVER 30 YEARS

Extensive Expertise Focusing on cross training Leveraging experience between licensing and inspection Using strategic workforce planning Preparing for the diverse workforce of the future

Building Partnerships Ensures transparency, diverse perspectives and close collaboration.

Proactively Monitoring and Preparing for the Future Aging Technological Mobile IT CISFs Increased Management Advancements Applications Transportation

Spent Nuclear Fuel Licensing Current Topics and Innovation John McKirgan Chief, Spent Fuel Storage and Transportation Licensing Branch Division of Fuel Management Of ce of Nuclear Material Safety and Safeguards

Transforming Graded Approach Flexibility Rulemaking our Licensing Framework to Risk Based on risk studies, Become a More Tool past safety evaluation reports, and staff expert Modern Risk- knowledge.

Informed Method of Continuation of Regulator Evaluation Graded Approach

MAP-12 GE 2000 Staff is Ready Transportation of fresh ATF assemblies Transportation of to Support ATF rod segments Transportation of ATF No changes to our regulatory framework are needed Proactive engagements Timely, safety focused licensing reviews

Proactively assessing readiness NRC's Regulatory Framework for Transportation remains robust Comprehensive regulations and licensing framework Continuous oversight framework Extensive domestic and international engagement Expanding public outreach

ISFSI and Transportation Inspection Program Implementation and Recent Innovations Anthony Dimitriadis Chief, Decommissioning, ISFSI and Reactor Health Physics Branch Division of Nuclear Materials Safety Region I

Spent Fuel Inspection Ensures Safety

Ensuring Safety in the Field Inspections include:

Construction of ISFSI pad Cask processing Transportation of Radioactive Material

Risk-informed Enhancements to Focus on the Most Significant Areas increased decreased inspection inspection hours hours These areas overlap with the operating reactor loading 5 Safety Focus Areas: radiation campaigns protection inspection program or Occupational Exposure canister Public Exposure processing problem id the decommissioning and Fuel Management resolution inspection program Canister Integrity fuel movement Impact to Plant Operations

Innovations CENTRALIZED DRY RUN in the INSPECTIONS Various sites represented at one location Inspection Observe and evaluate the dry run activities Program as would be done at each respective site.

USE OF TECHNOLOGY Use of cellular technology, laptops, and personal tablets to communicate with licensee personnel, observe cask preparation activities, and review documents.

Continue to Focus on our People Enhancing Integration of Inspection and Licensing Cross Training Sharing Expertise and Resources

Update on Spent Nuclear Fuel Research Activities Ricardo Torres, PhD Materials Engineer Division of Engineering Of ce of Nuclear Regulatory Research

Research as a Partner Proactively assessing research needs in support of safety reviews SUPPORTING NMSS READINESS Developing tools to risk-inform licensing and LICENSING AND oversight activities CERTIFICATION Engaged with our Federal partners to identify areas of RESEARCH cooperation OPERATING OVERSIGHT EXPERIENCE Leveraging outcomes of international research programs
