The Nuclear Regulatory Commission will hold a public meeting next week in Wake County to discuss the incident that caused the unplanned May 15 shutdown of the Harris Nuclear Plant, less than 25 miles from downtown Raleigh.
The NRC is still continuing a special inspection of the nuclear facility after plant operators discovered a flaw in the nuclear reactor that had had gone unnoticed for more than a year.
The NRC classified the problem as a degraded condition that could potentially lead to an uncontrolled radioactive release, but emphasized the situation never caused a threat to public safety.
The federal agency also said the flaw has been repaired and the plant is expected to resume operating soon. The NRC will issue a final inspection report in mid-July.
The Harris plant is operated by Raleigh-based Duke Energy Progress, a subsidiary of Charlotte-based Duke Energy. Duke acquired Progress a year ago as part of a corporate merger.
Last month plant operators discovered a 1/4-inch flaw in a nozzle in the lid of the nuclear reactor. The flaw suggested strain, wear or corrosion. The 6-inch-thick lid, or vessel head, contains the nuclear reaction and also the water inside that's superheated at extremely high pressure.
The flaw was discovered in ultrasonic test records conducted in the spring of 2012. It's not clear why the flaw went undetected for more than a year.
The NRC said that last year, the utility discovered four other small "indications" of potential flaws. They were fixed at the time.
The public meeting is scheduled for 6 p.m., Thursday, June 13, at the Holly Springs Cultural Center, 300 West Ballentine St., Holly Springs.
