Davis-Besse Nuclear Power Station Annual Assessment Meeting/Open House August 7, 2014 2013 Reactor Oversight Process Nuclear Regulatory Commission - Region III

Our Mission NRC Strategic Plan Goals To license and regulate the nations civilian use of Safety - Ensure adequate protection of public byproduct, source, and health and safety and the environment special nuclear materials to ensure adequate protection of public Security - Ensure adequate protection in the health and safety, secure use and management of radioactive promote the common materials defense and security, and protect the environment.

2 3 How We Regulate Reactor Oversight Process Strategic Performance Areas Safety

  • Establish rules and regulations Cornerstones
  • Issue licenses Performance Indicator Baseline Inspection Results Results
  • Provide oversight through inspection, enforcement, and evaluation of operational Significance Significance Threshold Threshold experience
  • Conduct research to provide support for Action Matrix regulatory decisions
  • Respond to events and emergencies Regulatory Response 4 5 1

Action Matrix Concept NRC Annual Assessment Summary DavisBesse Nuclear Power Station Licensee Regulatory Degraded Multiple/R ep. Unacceptable First Energy Nuclear Operating Company (FENOC)

Response Response Cornerstone Degraded Perform ance Cornerstone operated the Station safely and in a manner that preserved the public health and safety and protected the environment.

Increasing Safety Significance DavisBesse was in the Regulatory Response Column of the NRCs Action Matrix in the last Increasing NRC Inspection Efforts quarter of 2013.

DavisBesse transitioned to the Licensee Increasing NRC/Licensee Management Involvement Response Column on December 19, 2013.

  • Started first quarter of 2014; Completed second quarter of 2014 Verify that:
  • Openings made in Shield Building and Containment Vessel - Engineering evaluations and design changes are in
  • NRC inspected various pre-outage, conformance with facility license, codes, regulations outage activities, and plant restoration - Removal and replacement activities maintain nuclear and activities radiological safety in accordance with Federal regulations
  • Inspectors from NRC regional office and industry codes and standards with specialized backgrounds - Postinstallation test program was implementation is in supplemented the assigned two compliance with applicable codes and regulations resident inspectors 18 19 Steam Generator Replacement NRC Inspection Results
  • Containment vessel opening restored followed by satisfactory containment leakage integrity test Nuclear Regulatory Commission
  • Preoutage estimates for radiological doses was Region III consistent with doses actually received Lisle, Illinois
  • Upon plant startup and power operation, Steam Generators performed as expected and designed
