Radioactive tritium that is leaking from the Vermont Yankee nuclear power plant in Vernon is now believed to have reached the Connecticut River, and calls are growing for the plant to be closed down while the leak is located and repaired.
The owner of the 38-year-old plant, Louisiana-based Entergy Corp., is seeking to extend the plant's license 20 years beyond the scheduled 2012 expiration. However, in November, radioactive contamination was first detected in monitoring wells on the property, suspected of being from leaks in underground piping at the plant, which is by located alongside the Connecticut River.
Since then, the levels of contamination found in some wells has risen dramatically. The federal safety standard for tritium in drinking water is 20,000 picocuries per liter, but water from one monitoring well measured nearly 2.6 million picocuries per liter.
