Types of Nuclear Plants in NC
North Carolina’s nuclear plants are predominantly pressurized water reactors (PWRs), with the exception of the Surry nuclear plant, which is a boiling water reactor (BWR).
Key Players: Operators and Owners
The nuclear power plants in North Carolina are operated by two primary companies: Duke Energy Progress and Dominion Energy North Carolina. Duke Energy Progress, a subsidiary of Duke Energy, owns and operates six nuclear power plants, while Dominion Energy North Carolina, a subsidiary of Dominion Energy, operates one nuclear power plant.
Impact of Nuclear Power Plants in NC
North Carolina’s nuclear power plants play a critical role in the state’s energy mix, providing approximately 28% of the state’s electricity needs. In 2020, these plants generated a total of 64 billion kilowatt-hours (kWh) of electricity, reducing greenhouse gas emissions by approximately 63 million metric tons.
| Category | 2020 Data |
|---|---|
| Total Capacity (MW) | 4,236 |
| Total Generation (kWh) | 64 billion |
| Carbon Emissions (metric tons) | 63 million |
| Jobs | 4,500 |
| Economic Benefit (annually) | $550 million |
Safety and Regulation
North Carolina’s nuclear power plants are regulated by the Nuclear Regulatory Commission (NRC), the Federal Energy Regulatory Commission (FERC), and the North Carolina Utilities Commission (NCUC). The plants operate under a strict set of safety regulations, including the implementation of multiple redundant safety systems and active monitoring and maintenance of plant components.
Innovations and Upgrades
To ensure the safe and efficient operation of these plants, operators are continuously investing in innovative technologies and upgrades. Examples include:
- Enhanced water management systems: Improvements to cooling towers and storage systems to reduce environmental impact.
