Progress Energy addresses leak at power plant
There's no sign that high levels of tritium have migrated beyond the immediate area near the site of the leak, said Progress Energy spokesman Mike Hughes. He said the excretion was first noticed only recently and has been stopped.
Crews are working to find the specific source, and the Raleigh-based company will continue to assess its more than 100 monitoring wells around the plant.
The North Carolina company is the parent of Progress Energy Florida of St. Petersburg, whose sole nuclear power plant in Florida has been shuttered for more than a year undergoing repairs to a crack in its concrete housing.
