Yankee Rowe Nuclear Power Station

Yankee Rowe Nuclear Power Station was a pioneering commercial nuclear power plant located in the Berkshire Hills of western Massachusetts. It was the third commercial nuclear power plant in the United States and the first to be built without direct government funding, representing a critical step in the development of the civilian nuclear industry. Owned by the Yankee Atomic Electric Company, a consortium of New England utilities, the plant operated for over three decades before its permanent shutdown.

History

The project was initiated in the mid-1950s by the Yankee Atomic Electric Company, a group formed by several investor-owned utilities including Boston Edison and Western Massachusetts Electric Company. Its construction began in 1957, following the successful operation of earlier demonstration plants like the Shippingport Atomic Power Station in Pennsylvania. The site in Rowe, Massachusetts was chosen for its proximity to the Deerfield River, which provided cooling water, and its relative isolation. The plant's completion and connection to the New England Power Pool grid in 1960 marked a significant milestone for private investment in nuclear technology.

Design and specifications

Yankee Rowe was a pressurized water reactor (PWR), a design developed from naval propulsion technology used by the United States Navy. The reactor's nuclear steam supply system was manufactured by Westinghouse Electric Corporation, while the turbine generator was supplied by General Electric. The reactor core was housed within a distinctive spherical steel containment building, a design feature intended to withstand internal pressure. The station had a gross electrical output of 185 megawatts (MWe). Its primary coolant system operated at high pressure to prevent boiling, transferring heat to a secondary system to produce steam for the turbine.

Operational history

The plant achieved criticality in August 1960 and began commercial operation in November 1961. Throughout its operational life, Yankee Rowe was considered a reliable baseload generator for the New England grid. It underwent several power uprates and refueling outages, with its fuel supplied by companies like Babcock & Wilcox. In 1991, during a routine inspection, concerns were raised about the potential for neutron embrittlement in the reactor's steel pressure vessel. Subsequent analysis by the Nuclear Regulatory Commission and advisory bodies like the Advisory Committee on Reactor Safeguards led to a contentious safety review, ultimately contributing to the owner's decision to permanently cease operations.

Decommissioning and legacy

The reactor was shut down in February 1992. The decommissioning process, managed by Yankee Atomic Electric Company and later specialized firms like EnergySolutions, involved the removal of all fuel, which was shipped to the Idaho National Laboratory for storage. The major components, including the reactor vessel and steam generators, were dismantled and removed. The site entered a long-term monitoring phase, with the iconic containment structure demolished in 2007. Yankee Rowe is remembered as a successful proof-of-concept for privately financed nuclear power and its early operational data contributed to the design of larger subsequent plants like the Millstone Nuclear Power Plant and Oyster Creek Nuclear Generating Station.
