VERNON, Vt. — A nuclear energy company says the level of groundwater infiltrating a turbine building at its Vernon plant is falling.

Entergy Nuclear said 700 gallons of groundwater a day infiltrated the Vermont Yankee turbine building this month. Between 3,000 and 2,500 gallons had been infiltrating the building each day since January. The plant closed in 2014.

The company says ongoing drought conditions likely contributed to the drop and allowed for foundation cracks and a sump-pump drain to be sealed.
