A water leak containing Tritium has occurred at Perry Nuclear Power Plant. Tritium is a weakly radioactive isotope occurring in nuclear plant operations. It is found in self-luminescent items like wristwatches and aircraft dials.
The leak of water from a steam pipe was found on Monday afternoon. Samples taken at the site found tritium in the under drain system of the plant’s Auxiliary Building.
The plant says work is underway to repair the leak.
A spokeswoman for FirstEnergy says the water was captured and remains in a storage area under the plant and that the water did not go into the lake.
A Nuclear Regulatory Commission inspector has been notified of the event as required.
This is the second event in the past seven months at the plant.
In June 2013, the plant was shut down while maintenance workers repaired a contained leak of radioactive steam. On June 17, a busted weld on a vent line meant some steam that should be part of the reactor’s re-circulation system was seeping into a sump system chamber used to capture excess steam.
