Making Our Facilities Even Safer
The events in Japan at Fukushima on March 11, 2011 resulted in major changes at all ten Exelon nuclear energy facilities and across the industry. This short video was designed to inform our many stakeholders of those changes and demonstrate how we are incorporating the lessons learned from Fukushima to make Exelon’s facilities even safer and better prepared for the unimaginable.
The nuclear industry has the most sophisticated security and emergency preparedness plans in the U.S. industrial sector.
- Exelon Nuclear Emergency Preparedness
All Exelon facilities employ sophisticated emergency response plans to protect public health and safety. Visit the individual plant profile pages (listed below) to download emergency plans specific to each nuclear plant community. Read more about Exelon's efforts to keep the public safe.
- Emergency Planning - Nuclear Regulatory Commission (NRC)
Nuclear power plant owners, government agencies, state and local officials, as well as thousands of volunteers and first responders have worked together for more than 20 years to create a system of emergency preparedness and response that will serve the public well in the unlikely event of an emergency.

- Perspective on Radiation Release & Emergency Planning at U.S. Nuclear Power Plants - Nuclear Energy Institute (NEI)
Emergency planning zones (EPZ) around U.S. nuclear plants were determined in 1978 by a task force formed by the U.S. Nuclear Regulatory Commission, the U.S. Environmental Protection Agency, and the Federal Emergency Management Agency. Read more about how EPZs were determined and the continuous monitoring of radiological conditions at nuclear power plants. [PDF | 31 KB]

Protection from Earthquakes and Natural Disasters
The U.S. Nuclear Regulatory Commission requires nuclear power plants to be able to withstand the most severe natural phenomena that may occur in the region where they are located, including earthquakes, tsunamis, hurricanes, tornados, fires and floods. The NRC requires additional safety margins to account for any uncertainties and to ensure the plant can remain safe in the event that an accident and a severe natural phenomenon occur at the same time.

Safe Operations & Used Fuel Management
All Exelon Nuclear plants are able to safely shut down and keep fuel cooled even without electricity from the grid. Exelon safely stores its used fuel in used fuel pools or dry casks consistent with federal regulations.
- Radiological Monitoring at Exelon's Nuclear Plants
Exelon continuously monitors changes and trends in radiation levels to allow public health officials to make protective action recommendations if needed.

The industry provides information about the various methods for safely storing used nuclear fuel. [PDF 54 KB | Link to NEI]
- Monitoring Nuclear Plants to Protect the Environment - NEI
Nuclear power plant sites are among the most thoroughly studied and monitored environments. Environmental monitoring programs are under way even before plants go into service, ensuring that they are operating safely and protecting people and the environment. [PDF | 69 KB]
- FAQ on Japan - NEI
The U.S. nuclear energy industry has started an assessment of the events in Japan and is taking steps to ensure that U.S. reactors could respond to events that may challenge safe operation of nuclear facilities. This answers some of the most frequently asked questions about the events in Japan and the U.S. nuclear industry's response. [PDF | 218 KB]

Keeping Our Communities Safe
Every year, each Exelon Nuclear plant conducts an integrated exercise with state and local emergency organizations. These integrated exercises test and demonstrate the ability of Exelon and first responders to protect the public in the unlikely event of a plant emergency, as well as to respond to a hostile action at a plant. The NRC also participates in – and grades – emergency response drills to ensure readiness.
To download the emergency plan and safety fact sheet for each of Exelon's nuclear plants, please visit the individual plant profile pages below. The links to these downloads can be found on the right side of the profile page.
