Overview
Point Lepreau is a 660 MW nuclear power plant in New Brunswick, Canada. It is the only nuclear generating station in the province, providing a significant share of the region's baseload electricity.
Point Lepreau is a nuclear power plant located in New Brunswick, Canada, near the Bay of Fundy. With a capacity of 660 MW, it is a medium-to-large scale facility within Canada's nuclear fleet, which includes larger stations in Ontario. The plant is operated by NB Power and has been in service since 1983, making it a mature asset in the country's power generation mix. The plant uses a CANDU-6 pressurized heavy-water reactor design, which is a Canadian-developed technology. As a nuclear facility, it operates under the regulatory oversight of the Canadian Nuclear Safety Commission (CNSC), which enforces stringent safety and environmental standards. The plant's output is dispatched as baseload power, meaning it runs continuously to meet the minimum electricity demand of the grid. Point Lepreau plays a critical role in New Brunswick's energy landscape, supplying about 30% of the province's electricity. Its operation displaces fossil fuel generation, reducing greenhouse gas emissions. However, the plant has undergone significant refurbishment and faced extended outages, highlighting the operational challenges of aging nuclear infrastructure. The facility's location on the coast also requires careful management of cooling water discharges to protect marine ecosystems.
Environmental context
As a nuclear power plant, Point Lepreau produces no direct CO2, SOx, or NOx emissions during operation, making it a low-carbon electricity source. However, the facility's coastal location on the Bay of Fundy requires thermal discharge management to minimize impacts on local marine life. The plant's aging infrastructure and past refurbishment efforts raise considerations around waste management and decommissioning, though these are regulated by the CNSC. The surrounding region is sparsely populated, reducing immediate population exposure risks.
