UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August 8,2012 LICENSEE: Duke Energy Carolinas, LLC FACILITY: Oconee Nuclear Station, Units 1, 2, and 3
SUBJECT:
SUMMARY
OF JULY 11, 2012, MEETING WITH DUKE ENERGY CAROLINAS, LLC, TO DISCUSS ONGOING MAJOR PROJECTS AT OCONEE NUCLEAR STATION, UNITS 1, 2, AND 3 On July 11,2012, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of Duke Energy Carolinas, LLC (the licensee) at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting was to allow the licensee to update the NRC staff on the status of the ongoing major projects at the Oconee Nuclear Station, Units 1, 2, and 3 (ONS 1/213). A list of attendees is enclosed.
The licensee presented a summary of the status of the following major projects which are ongoing at ONS 1/2/3:
- Protected Service Water (PSW) system
- National Fire Protection Association (NFPA) Standard 805 Transition
- Installation of Main Steam Isolation Valves (MSIVs)
The licensee is currently replacing the existing RPS and ES systems in all three Oconee units with new state of the art digital systems. These systems are used to automatically actuate reactor shutdown and actuate ES systems if needed to maintain the reactors in a safe and stable condition. The licensee stated that the new RPS and ES systems are now operational in Units 1 and 3, with installation planned for Unit 2 during the fall 2013 refueling outage.
The licensee is in the process of installing a new PSW system. The PSW system is a diverse system to other plant systems for the mitigation of fires and high energy line breaks (HELBs).
The PSW system consists of new electrical power supplies for existing plant safety systems, as well as a replacement pump for the station auxiliary service water pump, which adds water to the steam generators in order to remove decay heat from the reactor coolant system once the reactor is shutdown, if the normal plant systems are not available. The installation of the PSW system will reduce the overall plant risk in the event of a fire or HELB at the Oconee site.
During the meeting, the licensee indicated that although the majority of the system has been installed, they are experiencing delays in completing the PSW system installation. The licensee will submit a formal request to the NRC to extend the required completion date of January 1, 2013.
-2 ONS 1/2/3 was one of two pilot plants that are in the process of transitioning to NFPA 805 for compliance with the NRC fire protection regulations, Title 10 of the Code of Federal Regulations, Part 50, Section 50.48. The NRC staff completed its review of the license amendment request requesting approval of the transition, and issued the license amendments approving the transition on December 29, 2010 (Agencywide Documents Access and Management System Accession No. ML103630612). The licensee indicated during the meeting that they are working on the modifications required by the license amendments, but may need additional time to complete some of the modifications, such as the PSW system and the fire detection improvements.
The licensee plans to install new MSIVs for all three Oconee units. The MSIVs will provide additional margin to ensure HELBs can be mitigated. During the meeting, the licensee stated that the target date to submit a license amendment request to the NRC is January 2013. The MSIVs have been ordered from a vendor, and a detailed scope for the MSIVs installation is being developed.
No members of the public were in attendance at the meeting. Public Meeting Feedback forms were made available at the meeting. As of the date of this meeting summary, no feedback forms have been received. The NRC and the licensee also held a non-public portion of the meeting. This portion of the meeting was closed to the public because sensitive security-related information was discussed.

Protected Service Water Installation Status Challenges Procurement Document Processing - Mitigation strategy: 1) Added more engineering resources from other projects to review and process documents. 2) Maintain presence in vendor shops to ensure the correct priority is given to our equipment documentation cycle time and quality.
Engineered Equipment Delivery - Mitigation strategy: 1) Major Projects Management and expeditors continue to travel to vendor shops on a regular basis. 2) Major Projects craft crews are sent to the vendor shops to perform point to point wiring checks to ensure quality before the equipment is shipped.
Completion of Engineering Change Packages - Timely delivery of vendor documents continue to challenge completion of the engineering packages. Mitigation strategy: 1) Adding engineering resources to the project both at Duke and in the vendor shops. 2) Sending resources to vendors shops to shorten document cycle time.
