Chicago, Illinois based Exelon Corporation recently announced that it will close the Oyster Creek nuclear power plant in 2019. (NY Times, NJ.com AP). Oyster Creek, in Lacey, New Jersey, is the nation’s oldest operating nuclear power plant. It’s roughly 75 miles south of New York City and 60 miles east of Philadelphia. Exelon was recently granted a 20-year extension on its operating license by the Nuclear Regulatory Commission despite the wishes of local environmentalists, environmental groups, and people concerned about evacuations in the event of an emergency, and public concerns from the NJ Department of Environmental Protection.
The plant uses a single pass cooling system which sucks in 500 Billion gallons of cool water each year (click here) from Barnegat Bay, heats it 20 to 30 degrees, and returns the heated water to the bay. This kills billions of adult and juvenile fish, clams, crabs, and shrimp, and hundreds of billions, if not trillions of hatchlings, less than a centimeter in length. This has had a negative effect – possibly a disastrous effect – on the fish and wildlife populations of Barnegat Bay during the 40 year operating life of the plant to date. The NJ DEP demanded that Exelon retrofit the plant with cooling towers.
Exelon claims the cooling towers would cost $600 million, roughly $1.00 per watt for the 610 megawatt reactor. Other estimates for the cooling towers range from $200 million to $800 million. Exelon decided to close the plant rather than spend the money on the cooling towers and other maintenance. This is a gain for current Exelon shareholders as they defer a hundreds of millions on capital improvments, and corresponding hundreds of millions of liabilities, while they collect revenues and realize profits from the sale of electricity for the next nine years.
