Millstone nuclear plant in Connecticut requested to significantly expand nuclear waste storage capacity and the Connecticut Siting Council has approved the plan.
The council voted unanimously without discussion Thursday to allow Millstone to build concrete pads necessary for an expansion of its waste storage at the Waterford site.
The plant could add as many as 135 dry casks storage units by 2045. There are 19 now.
Millstone Power Station’s owner Dominion Resources Inc. asked for permission to expand storage because federal officials have not found a central site for nuclear waste. Spokesman Ken Holt said increasing storage at the local site is not Dominion’s first choice.
In dry cask storage, spent fuel cooled for at least a year is surrounded by inert gas in casks, which are typically steel cylinders welded or bolted closed.
