Pilgrim is one of the worst-rated nuclear facilities in the United States. Ever since it generated its first kilowatt of electricity, in December of 1972, it has been beset with mechanical failures and lapses in safety. In a single four-week stretch this summer, the plant was offline for a total of fifteen days because of a malfunctioning steam-isolation valve, elevated water levels in the reactor, and other problems. For years, Pilgrim’s detractors have kept steady pressure on Entergy and state officials through local protests, a sit-in at the governor’s office, and legal action. Last October, in a partial victory for activists, the company announced plans to shutter the plant, citing the expense of keeping it running in the face of cheap, abundant natural gas and increasingly competitive “renewable-energy resources.” The reactor is scheduled to go dark on May 31, 2019. But that won’t end Pilgrim’s saga. Come June 1st, the plant will still host more than eight hundred tons of irradiated spent fuel. Most of the waste is currently stored in a forty-foot-deep pool of water, suspended four stories aboveground, next to the reactor core. The pool, which was designed to hold eight hundred and eighty fuel assemblies, now contains more than three times that number. (A federal regulatory waiver has allowed Entergy to pack the pool more densely than originally planned, a move repeated by operators across the country.) The National Academy of Sciences has warned that if the cooling system in a plant like Pilgrim failed, there would be little time before the water in the pool boiled away and exposed the radioactive rods to air. The resulting fire, the N.A.S. and anti-nuclear watchdogs have cautioned, could send across Cape Cod and northern New England many times the amount of radioactive cesium-137 released in the Chernobyl disaster. “Pools like the one at Pilgrim Nuclear Power Station are a disaster waiting to happen,” Senator Ed Markey, a Democrat from Massachusetts, told us in an e-mail.
