SUMMARY
OF JULY 13, 2007, PUBLIC MEETING WITH DUKEPOWER REGARDING PILOT PLANT TRANSITION TO NATIONAL FIRE PROTECTION ASSOCIATION STANDARD 805On July 13, 2007, the U.S. Nuclear Regulatory Commission staff from Headquarters andRegion II participated in a public meeting with Duke Power to discuss Oconee Nuclear Station transition to the National Fire Protection Association (NFPA) Standard 805.
The meeting took place at the Oconee site in Seneca, South Carolina. This public meeting followed a non-public NFPA 805 observation visit also held at the Oconee site on July 10, 11, and 12, 2007. Enclosed are a list of the meeting participants (Enclosure 1) and a summary of the discussiontopics and status (Enclosure 2).
