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 OfØce of Nuclear Material Safety and Safeguards
Assuring Safety through a Robust and Comprehensive Program Review and certify packages for transportation of nuclear materials License spent fuel storage facilities and certify storage casks 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 OfØce of Nuclear Material Safety and Safeguards
Comprehensive, performance based and risk informed regulations Ensure safety based on data driven decision making in all technical areas Observe critical activities, respond to events, and take enforcement where necessary Periodic inspections at all stages of the fabrication, design and use of casks Enhancements to focus on areas most important to safety Robust Regulatory Framework Licensing Oversight Strong Tenet of Regulations, Licensing, Oversight RESULT: SAFE STORAGE AND TRANSPORT OF SPENT NUCLEAR FUEL FOR OVER 30 YEARS
Focusing on cross training Leveraging experience between licensing and inspection Using strategic workforce planning Preparing for the diverse workforce of the future Extensive Expertise
Building Partnerships Ensures transparency, diverse perspectives and close collaboration.
Proactively Monitoring and Preparing for the Future Aging Management Technological Advancements CISFs Applications Mobile IT Increased Transportation
Spent Nuclear Fuel Licensing Current Topics and Innovation John McKirgan Chief, Spent Fuel Storage and Transportation Licensing Branch Division of Fuel Management OfØce of Nuclear Material Safety and Safeguards
Transforming our Licensing Framework to Become a More Modern Risk-Informed Regulator Graded Approach Risk Tool Based on risk studies, past safety evaluation reports, and staff expert knowledge.
Method of Evaluation Continuation of Graded Approach Flexibility Rulemaking
Staff is Ready to Support Transportation of ATF MAP-12 Transportation of fresh ATF assemblies GE 2000 Transportation of ATF rod segments No changes to our regulatory framework are needed Proactive engagements Timely, safety focused licensing reviews
Proactively assessing readiness Comprehensive regulations and licensing framework Continuous oversight framework Extensive domestic and international engagement Expanding public outreach NRC's Regulatory Framework for Transportation remains robust
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
Inspections include:
Construction of ISFSI pad Cask processing Transportation of Radioactive Material Ensuring Safety in the Field
Risk-informed Enhancements to Focus on the Most Significant Areas c a n i s t e r p r o c e s s i n g r a d i a t i o n p r o t e c t i o n p r o b l e m i d a n d r e s o l u t i o n f u e l m o v e m e n t i n c r e a s e d i n s p e c t i o n h o u r s d e c r e a s e d i n s p e c t i o n h o u r s These areas overlap with the operating reactor inspection program or the decommissioning inspection program 5 Safety Focus Areas:
Occupational Exposure Public Exposure Fuel Management Canister Integrity Impact to Plant Operations c a m p a i g n s l o a d i n g
Innovations in the Inspection Program USE OF TECHNOLOGY CENTRALIZED DRY RUN INSPECTIONS Use of cellular technology, laptops, and personal tablets to communicate with licensee personnel, observe cask preparation activities, and review documents.
Various sites represented at one location Observe and evaluate the dry run activities as would be done at each respective site.
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 OfØce of Nuclear Regulatory Research
Research as a Partner Proactively assessing research needs in support of safety reviews Developing tools to risk-inform licensing and oversight activities Engaged with our Federal partners to identify areas of cooperation Leveraging outcomes of international research programs SUPPORTING NMSS READINESS L I C E N S I N G A N D C E R T I F I C A T I O N O P E R A T I N G E X P E R I E N C E O V E R S I G H T R E S E A R C H
