Hope Creek Nuclear Generating Station is located in Lower Alloways Creek Township, Salem County, New Jersey, and is owned and operated by PSEG Nuclear LLC, a subsidiary of Public Service Enterprise Group. It occupies an artificial island shared with the neighboring Salem Nuclear Power Plant.
The facility operates a single boiling water reactor (BWR) manufactured by General Electric. Although originally designed to include two reactors, the second unit was canceled in 1981. Hope Creek's generating capacity stands at 1,268 megawatts electric (MWe), with commercial operation commencing on July 25, 1986. Initially licensed until 2026, PSEG obtained a license renewal in 2011 extending its operational life through 2046.
Combined with the Salem Nuclear Power Plant, the Salem–Hope Creek complex delivers a total output of 3,572 MW, ranking it as the largest nuclear power site in the Eastern United States and fourth largest nationwide. This complex contributes roughly 40% of New Jersey’s electricity and accounts for approximately 85% of the state’s carbon-free energy supply, making it a vital component of New Jersey’s power infrastructure.
Hope Creek is one of three authorized nuclear reactors in New Jersey; the other two units are located at Salem. In 2021, nuclear generation provided 45% of the state’s electricity consumption.
In 2019, New Jersey awarded its nuclear facilities Zero-Emission Certificates valued at $300 million per year to support continued operation. This financial incentive concluded in 2024 and will cease on June 1, 2025, as federal clean energy tax credits established by the Inflation Reduction Act now underpin clean energy initiatives.
Plant features
Hope Creek operates a boiling water reactor (BWR), which contrasts with the pressurized water reactors (PWR) used at the nearby Salem Nuclear Power Plant units. Its sole reactor generates power and utilizes a large natural-draft cooling tower that is visible from extensive distances across Delaware, New Jersey, and Maryland. Unlike Salem’s once-through cooling system, Hope Creek’s cooling tower exclusively serves its reactor.
A distinctive aspect of Hope Creek is its cylindrical reactor containment building topped with a dome that visually resembles PWR containment structures. However, the actual containment system comprises a separate drywell/torus vessel located inside this building, which functions as secondary containment and houses essential safety equipment.
Controversies and safety concerns
On October 10, 2004, Hope Creek experienced a steam leak that resulted in an automatic shutdown. Operators observed irregularities including fluctuating reactor pressure, water level variations, and malfunctions in the high-pressure coolant injection system—a critical safety mechanism. The Nuclear Regulatory Commission (NRC) responded by intensifying regulatory oversight.
This event heightened attention on safety protocols and management practices at both Hope Creek and Salem plants. Former employees and advocacy groups raised allegations against management for postponing maintenance activities and discouraging reporting of safety issues. Delaware senators, among them then-Senator Joe Biden, called upon the NRC to address persistent concerns regarding management effectiveness and safety culture.
Due to maintenance backlogs, equipment deficiencies, and an organizational culture impeding safety communication, the NRC placed both facilities under special oversight. Subsequent investigations prompted enhancements in employee training programs and revisions to operational procedures aimed at remedying identified shortcomings.
Surrounding population
The Nuclear Regulatory Commission identifies two key emergency planning zones around nuclear facilities: a 10-mile zone addressing airborne radioactive contamination exposure, and a 50-mile zone focusing on potential contamination through ingestion of food and beverages.
As of 2010, the number of residents living within 10 miles of Hope Creek reached 53,811, marking a 53.3% rise compared to the previous ten years. The population within a 50-mile radius stood at 5,523,010, reflecting a 7.5% growth since 2000.
Significant urban areas located within 50 miles include:
- New Jersey: Camden (39 miles), Vineland (27 miles), Pennsville Township (12 miles), Salem (8 miles)
- Delaware: Dover (21 miles), Wilmington (19 miles)
- Pennsylvania: Philadelphia (43 miles)

Seismic risk
According to a 2010 assessment by the Nuclear Regulatory Commission, the likelihood of an earthquake leading to core damage at Hope Creek is estimated at approximately one in 357,143 per year.
