Enhancing Safety at America’s Nuclear Energy Facilities U.S. Industry’s Fukushima Response Joseph Pollock, Nuclear Energy Institute Christopher H. Mudrick, Exelon Nuclear Timothy S. Rausch, PPL Susquehanna James H. Lash, FirstEnergy Generation March 27, 2012

Fukushima Daiichi Today  Reactors stabilized  New cooling systems operating  Decontamination under way  Debris removal continues  Assessing long-term impact of radiation releases 2 Source: Associated Press

U.S. Response to Enhance Safety  Reconfirmed safety of U.S. reactors immediately after events in Japan  Established a factual basis for action through extensive analysis of the events in Japan  U.S. industry bias for action results in actions and commitments in advance of NRC regulatory action

Proactive Industry Actions  Industry initiated plant inspections and evaluations provide foundation for more effective and quicker implementation of enhancements – Flood protection – Protection against earthquakes – Manage and mitigating a complete loss of electrical power – Instrumentation and containment integrity
