Federal regulators say the first of two leaks of radioactive tritium this year at the nation's oldest nuclear power plant did not spread contamination beyond the plant's grounds.
The U.S. Nuclear Regulatory Commission says its investigation of an April tritium leak at the Oyster Creek Nuclear Generating Station found that groundwater contamination has not left the site of the Lacey Township plant.
Tuesday's report did not address a second leak that occurred last month. It will be the subject of a separate report this year.
The plant got a new 20-year license in April and will be 60 years old at the end of it.
