The Millstone Nuclear Power Station, located in Waterford, Connecticut on the shore of Long Island Sound, has been a subject of concern for FISH Unlimited due to its impact on local marine ecosystems. The plant's cooling water intake systems have been responsible for the deaths of millions of fish each year.
Northeast Utilities, the operator of the Millstone plant, has documented significant fish kills at the facility. These reports show the devastating impact of the plant's once-through cooling system on local fish populations.
