1 Nuclear Generation Event Response: Strengthening Safety After Fukushima Jim Scarola Executive Director US Industry Fukushima Response 1

2 Industry Response Coordination The Way Forward Fukushima Response Steering Committee Nuclear Supplier Owner s Groups EPRI INPO NEI Strategies for EOP, SAMG, EDMG, FLEX Venting & filtering strategies Technology use and advancement External event assessment Land contamination strategy development Event analysis and lesson learned Immediate actions for U.S. industry Strengthening technical assistance for emergencies Industry coordinated response Regulatory interface and prioritization Stakeholder communications Assist/Facts/Root Cause/Lessons Learned/Timely Response 2

3 Safe Even During Extreme Events April 28, 2011 Safety maintained at Browns Ferry during tornados that knocked out offsite power and damaged 200 transmission towers June 26, 2011 Safety maintained at Ft. Calhoun historical Missouri River flooding August 23, 2011 Safety maintained at North Anna during strongest earthquake on record 3

4 Staffing & Roles Emergency Facilities Single Unit Design Basis Accident On- & Off- Site Casualties Command Control Authority Multi-Unit Beyond Design Basis Accident Local Infrastructure Rare, yet Credible, Extreme Regional Event Cliff Edge Response Communications Socio- Economic Impact 4

5 The Industry Promotes Actions in the Area of Overlap Actions to Prevent Core Damage Fulfill All Goals Public Safety Environmental Protection Economic Security 5

6 Safety Assurance for Unpredicted Events Initiating Events Seismic Flood Unknown I Design Basis (Redundancy & Qualification) Cooling / Make-up Water Power II Beyond Design Basis (Diversity & Quantity) Portable Pumps Portable Generators Satellite Radios III Fuel Damage Impact Management (Coordinated Response) Venting and Filtration Evacuation / Shelter Potassium Iodine IV Recovery After Stabilization (Assistance & Future Prevention) Quick Hits Apparent Root Cause Lessons Learned Protecting Public and the Environment Battery Packs Distribution Industry Support Compressors / Gas Bottles Industry Response OP / AOP / EOP / SAMG / EDMG

7 Diverse backup safety measures are the key to maintaining safety functions following an extreme event Adding safety margin to current design may fall short or be misdirected in preparation for the unknown Portable equipment is the foundation of security strategies and eventually mitigated the event at Fukushima Provides flexibility for the ERO to respond to unpredicted impacts 7

8 Emergency Response Adding Layers of Safety Current Emergency Plans SAMGs Plus On Site FLEX Emergency Plans SAMGs On- Site FLEX Plus Regional Centers and Industry Response Capability Upgraded Emergency Plans with Industry Response Capability Upgraded SAMGs with Filtering Strategy Regional Response Centers On- Site FLEX Mitigation Protection SBO Coping Capability Design Basis External Events SBO Coping Capability Design Basis External Events SBO Coping Capability Design Basis External Events

9 Proper Balance, Integration and Authority Ensuring the INTEGRATION of Ops, AOPs, EOPs, EDMGs, and FLEX based on sound engineering Ensuring the PROPER BALANCE of training on normal, abnormal, emergency, and severe accidents Strategy/ Procedures Training/ Proficiency Ensuring the proper AUTHORITY to timely implement specified actions to prevent and mitigate Command/ Control Accident Management & Human Performance 9

10 Leaders understand the potential for cliff edge impact of new information Leaders set the expectations of technical rigor and timely disposition of new information Leaders own the emergency preparation for rare but extreme events Leaders value the importance of independent oversight in assuring safety Leaders assure the business structure promotes the continuous improvement of safety 10
