Surry Nuclear Power Plant

Surry Nuclear Power Plant is a dual-unit nuclear power station located in Surry County, Virginia on the southern bank of the James River. Owned and operated by the utility Dominion Energy, the plant has been a significant source of baseload power for the Virginia region since the early 1970s. Its two pressurized water reactors were supplied by the Westinghouse Electric Company and have undergone numerous upgrades to extend their operational licenses.

History and construction

Planning for the facility began in the mid-1960s amid a national push for nuclear power in the United States. Construction was led by Stone & Webster and commenced in 1968, with Unit 1 entering commercial operation in December 1972, followed by Unit 2 in May 1973. The site selection on the James River was strategic, providing an ample cooling water source and proximity to major load centers like Hampton Roads. The project was a significant capital investment for the then-owner Virginia Electric and Power Company, which later became part of Dominion Energy.

Design and technical specifications

Each unit houses a three-loop pressurized water reactor designed by Westinghouse Electric Company, with a generating capacity of approximately 933 MWe per unit. The reactors use uranium dioxide fuel assemblies and are contained within robust containment buildings designed to withstand external events. The plant's turbine generators were supplied by General Electric, and the facility utilizes a mechanical draft cooling tower system to dissipate waste heat into the atmosphere, minimizing thermal impact on the James River.

Operational history and incidents

The plant has experienced several notable events during its long service. In 1986, a steam generator tube rupture in Unit 2 led to a release of primary coolant, though without significant radiological consequences. A more serious accident occurred in 1972 when a turbine generator overspeed incident caused significant damage to the turbine hall. The facility has also been scrutinized following events like the Three Mile Island accident and Fukushima Daiichi nuclear disaster, prompting comprehensive safety reassessments and upgrades from the Nuclear Regulatory Commission.

Safety and environmental impact

Safety systems at the station include redundant emergency core cooling systems, containment spray systems, and hardened ventilation filters. The plant conducts regular drills with agencies like the Federal Emergency Management Agency and maintains an extensive emergency planning zone. Environmental monitoring is continuous, with the United States Environmental Protection Agency and the Virginia Department of Environmental Quality overseeing discharges and impacts on the Chesapeake Bay watershed. The plant's spent nuclear fuel is stored on-site in robust dry cask storage systems.

Economic and community role

The facility is a major economic engine for Surry County, Virginia, providing hundreds of high-skilled jobs and contributing significantly to the local tax base, which funds public schools and county services. It produces a substantial portion of the electricity for Dominion Energy Virginia customers, supporting the regional grid operated by PJM Interconnection. The plant also engages in community partnerships and educational initiatives, often collaborating with institutions like Virginia Tech and Tidewater Community College.
