SUBJECT:
MEETING
SUMMARY
OF SEPTEMBER 23, 1993 Representatives from Carolina Power & Light Company (the licensee) met with the Nuclear Regulatory Commission (NRC) staff on September 23, 1993, at the NRC offices in Rockville, Maryland. The meeting was requested by the licensee to discuss the status of activities associated with crack indications observed in the Unit I core shroud. The attendees at the meeting are listed in Enclosure 1 and a copy of the slides presented at the meeting are given in Enclosure 2.
The licensee described the inspection activities that had taken place during the previous month. Specifically, the licensee discussed the in-vessel inspection efforts with regard to the H3 and H4 welds. The H3 weld joins the top guide support plate to the mid-portion of the shroud, and the H4 weld is' a circumferential weld between two shroud shell courses in the mid-core region.
The licensee indicated that a complete visual inspection of the inside diameter of the shroud above the lower core plate would be conducted. A description of the variable causal factors for the shroud cracking was presented. These factors included the electro-chemical corrosion potential in the various regions, the axial and circumferential fast neutron fluence distributions, and the fabrication orientations of the plate material. Based on these factors and their variation among the different weld regions, the licensee presented their plans for performing the inspections of t,1e other l shroud surface areas. !
l The licensee also provided some details of the ultrasonic test (UT) equipment I and supporting data acquisition system that would be used to characterize the crack dimensions. The UT equipment would incorporate 45 and 60 refracted longitudinal wave (RL) transducers. Measurements within each 12-inch long i scanning segment would be performed at 0.05-inch increments. The data acquisition would be via the General Electric (GE) SMART 2000 System.
The licensee discussed the development of core shroud analyses methodology and evaluation acceptance criteria. The licensee committed to provide this i information to the NRC staff for review. The NRC staff noted that the evaluation of specific weld areas should include sufficient crack :
characterization and an agreement on projected crack growth rates. Finally, l the licensee presented a brief discussion of crack mitigation options that j were being pursued with assistance from GE and a description of the repair !
contingency for the crack in the H3 weld.
