Nuclear: An Ideal Foundation for Our Clean Energy Future
Limerick Clean Energy Center's two nuclear reactors in Pottstown, Pennsylvania can produce up to 2,317 megawatts (MW) of clean, carbon-free energy, enough electricity to power the equivalent of more than 1.7 million homes. Limerick sits on a 600-acre site and draws its cooling water from the Schuylkill River.
U.S. nuclear energy facilities are initially licensed to operate for 40 years and a Nuclear Regulatory Commission (NRC) rule allows licensees to apply for initial and subsequent license renewals of up to 20 years each after the initial 40-year term. The NRC approved initial license renewal for Limerick on October 20, 2014, authorizing operation for Unit 1 and Unit 2 through 2044 and 2049, respectively.
Safety is Constellation’s first and most critical obligation. Nuclear power plants are among the best-protected private sector facilities in America, with monitoring and inspections by plant owners, local officials, and the federal government.

Limerick Clean Energy Center has been part of the Pottstown community for decades, providing hundreds of well-paying jobs and millions of dollars in economic support, including about $5.3 million in taxes annually for schools, roads, and other public services.
Limerick Clean Energy Center is referenced in legal and regulatory filings as Limerick Generating Station.

Shadow Evacuation
People should only evacuate when instructed to do so. Evacuation of individuals not within the declared evacuation area could impede evacuation traffic flow. Monitor the radio or TV and prepare to follow instructions.
Staged Evacuation
You may be instructed to shelter-in-place until people in a higher risk area are evacuated. Monitor the radio or TV and prepare to follow instructions.
Information for Farmers
When advised to do so, remove all livestock from pasture, shelter if possible and provide them with stored feed and protected water. The county U.S. Department of Agriculture representative will provide further instructions regarding the protection of livestock and foodstuffs.
School Information
If your child’s school is in session at the time evacuation is recommended, children attending schools located within the emergency planning zone will be transported to designated host schools outside the area. They will remain under supervision until reunited with parents or guardians. These host schools have been planned to coincide with main evacuation routes. Children whose homes are inside the emergency planning zone, but who attend school outside the emergency planning zone, will not be sent home if an evacuation is recommended. They will follow the specific plans designated in the district’s emergency procedures. See the “County-specific School Information” within this brochure or contact school officials for more information.
Non-Public School and Day Care Information
Parents and guardians with children attending non-public schools or at day care facilities within the emergency planning zone should become familiar with the facilities’ emergency plans. Contact the facility operator for more information.

The sirens generate a loud, continuous pitch for at least three minutes.
If you hear a siren, you should tune to one of the Emergency Alert System (EAS) stations listed in this site for official information.
