SUMMARY

- MEETING WITH DUKE ENERGY CORPORATION ON POLYETHYLENE PIPING USE FOR SAFETY RELATED BURIED SERVICE WATER PIPING AT CATAWBA NUCLEAR STATION (TAC NOS. MC7294 AND MC7295)

Representatives of Duke Energy Corporation (Duke, the licensee) and the Electric Power Research Institute (EPRI), met with members of the Nuclear Regulatory Commission (NRC) staff at NRC Headquarters on June 27, 2005, in Rockville, Maryland. The meeting addressed issues related to a potential relief request to be submitted by the licensee in the Fall/Winter of 2005, for Catawba Nuclear Station (Catawba), Units 1 and 2. These issues concerned Dukes plans to use buried high-density polyethylene (HDPE) piping for the safety related service water system in order to address problems with corrosion, sedimentation, and biological fouling in the current carbon steel piping. A list of attendees is provided in Attachment 1 and the handouts provided in the meeting are included in Attachment 2.

SUMMARY

OF MEETING Dukes presentation utilized the enclosed handout entitled, Catawba Nuclear Station, Polyethylene Piping Use for Safety Related Buried Service Water Piping. Duke presented this information for two purposes. First, it would familiarize the NRC staff with the details of the possible relief request. Second, the licensee would use the comments and feedback given by the NRC to help focus its efforts to develop the relief request.

Currently at Catawba, the Nuclear Service Water System and the Low Pressure Service Water System combine for approximately 45,000 to 50,000 feet of piping. Because of the unique chemistry of Lake Wylie, the lake used for the source of the service water, the licensee has seen a history of cooling flow restrictions, caused by corrosion products, sedimentation, biological growth, and clams fouling the components within the system. Furthermore, this environment has promoted through-wall pitting of the current steel Nuclear Service Water System piping.

In an effort to curtail these problems, the licensee may propose using HDPE piping for the safety-related Nuclear Service Water System. Duke has around 10 years of experience using HDPE piping, which it has found shows superior corrosion and biological buildup resistance.

Furthermore, Duke stated that the British Energy Sizewell B Plant has obtained approval and has installed HDPE in the American Society of Mechanical Engineering (ASME)Section III, Class 3 emergency service water system. The licensee also discussed the other industrial uses of polyethylene piping, including the natural gas and the water treatment industries.

To provide further information on the piping, Duke brought samples of the welded piping and explained the status of the ASME code development for HDPE. The EPRI representatives then

discussed the seismic analysis and the non-destructive examination techniques used for the HDPE. The NRC staff asked numerous questions and provided constant feedback during the meeting.

CONCLUSION At the conclusion of the meeting, the licensee indicated that it would use the information gathered to aid in the development of its relief request. Duke expects to submit this relief request some time in the Fall/Winter of 2005.

No members of the public attended this meeting. There were no public comments.

Sincerely,

/RA/
