SUMMARY
OF SEPTEMBER 25, 2007, MEETING WITH REPRESENTATIVES OF SCE ON CONTROL ELEMENT DRIVE MECHANISM PENETRATION 56, EVALUATION METHODS AND RESULTS, AND FUTURE PLANS REGARDING INSPECTIONS AND HEAD REPLACEMENT On September 25, 2007, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of SCE, the licensee for SONGS 3, at NRC Headquarters, One White Flint North, 11555 Rockville Pike, Rockville, Maryland. The purpose of the meeting, held at the request of the licensee, was to present to the NRC staff the licensee's evaluation of the indications in the Unit 3 Control Element Drive Mechanism (CEDM) penetration 56 and its decision, based on the information available to date, to reclassify the indication in CEDM 56 as No Detectable Defect.
SCE presented the findings at refueling outages (RFOs) 12, 13, and 14, discussed the technical basis and licensing issues associated with the reclassification, and outlined the future plans.
Reanalyses of all inspection data on a consistent basis concluded no discernable change since the indication was first detected in RFO 12. In addition, the evaluations concluded that the indication was consistent with grain noise, not primary water stress-corrosion cracking.
Future plans included continuing with the EA-03-009 examinations at every RFO, respond to any new indications or unexpected changes as appropriate, and replace the SONGS Unit 3 reactor vessel head during RFO 17 (approximately in the fall of 2012).
A list of attendees is provided as an enclosure to this memorandum. One member of the public was in attendance. No Public Meeting Feedback forms were received.
The slides used during the meeting by SCE are available in the Agencywide Documents Access and Management System under Accession No. ML072750013. There were no handouts from the NRC staff.
Please direct any inquiries to me at 301-415-1480, or nxk@nrc.gov.
