‘Unusual event’ at Oyster Creek nuclear plant

Operators at the nation’s oldest nuclear plant have terminated an “unusual event” status that was briefly declared after staffers detected an odor of chlorine at the plant’s intake structure.

The declaration at the Oyster Creek plant in Lacey Township occurred at 10:34 a.m. Wednesday.

Plant officials say the odor was emanating from piping that provides service water to plant systems. The leak was isolated and the odor dissipated, and officials say it posed no threat to plant workers, the environment or the public.

The “unusual event” declaration — which is the lowest of four levels of emergency classification — was terminated at 11:40 a.m. Normal plant operations continued while the declaration was in effect.

Oyster Creek is located about 60 miles east of Philadelphia.
