Tank leaking tritium at LaSalle plant fixed
SENECA -- Exelon Nuclear has fixed a tritium leak found at its LaSalle plant last month.
Exelon officials say ultrasound tests on a water tank found no problems after three holes about as big as the head of a thumbtack were repaired.
The tritium was found in a monitoring well in the middle of the LaSalle Station site.
The company says it wasn't found anywhere else, and no people were in danger because of it.
Tritium is a radioactive form of hydrogen that's created as a byproduct of nuclear power plant operations. Environmental officials say exposure to tritium can increase cancer risks.
