Map of North American Nuclear Sites
Nuclear power plays a significant role in North America’s energy landscape, providing a stable and low-carbon source of electricity. The United States is the world’s largest producer of nuclear energy, with over 90 reactors generating about 20% of the nation’s electricity. Canada also contributes, leveraging its expertise in CANDU reactors, which use natural uranium as fuel. Mexico, though smaller in scale, operates the Laguna Verde Nuclear Power Plant, which generates a portion of the nation’s electricity. Nuclear power is highly valued for its ability to deliver consistent energy without greenhouse gas emissions during operation, aiding efforts to combat climate change. Find out where the continent’s nuclear sites are located, and what goes on at each of them, on our interactive map of North American nuclear sites.
Quick Guide to using the Map of North American Nuclear Sites
MAP – Click and drag to move the map around. Hold Ctrl and use the mouse wheel to zoom in or out. Alternatively use the zoom buttons in the top right corner.
POINTS – Points are coloured based on the purpose of the nuclear site.
COUNTER – The counter in the top left displays the number of nuclear sites under each purpose. Clicking on a specific counter lets you see only sites that fall within that category.
POPUPS – Hovering over a specific point on the map will show you a popup containing additional information about the site.
