Committed to Safety
Limerick Generating Station, like all U.S. nuclear energy facilities, is based on a “defense-in-depth” design, which means there are redundant layers of safety. There are multiple layers of safety systems to provide water to the reactor core. These safety systems, and their backup safety systems, are powered by multiple and redundant power sources. Nuclear energy plants are built with multiple physical barriers, including thick, steel-reinforced concrete walls around the reactor to contain radioactive materials.
Our employees are personally committed to safety. They are highly-skilled workers and continually receive training to make our safe work practices even safer. We have a culture of continuous learning and implement lessons learned from operating experience to continue to operate safe nuclear energy facilities. Each employee has 100 percent accountability. We welcome strict, daily oversight by the Nuclear Regulatory Commission (NRC). We work with the NRC to ensure that all regulations are complied with - and exceeded.

Limerick Generating Station is committed to producing safe and reliable electricity for Pennsylvania, and as part of this commitment we applied to the Nuclear Regulatory Commission (NRC) for a 20-year renewal of our original operating license. We are committed to running Limerick cleanly, safely and reliably well into the future.

Supporting the Local Economy
Limerick Generating Station is a valuable resource to the surrounding community. In addition to the electric reliability and environmental benefits that the plant provides, Limerick Generating Station provides direct and indirect economic benefits to its host community and Pennsylvania, including over $200 million in economic contributions annually to Pennsylvania.
Continental Economics, Inc. prepared a report that analyzes the economic, system reliability and environmental benefits of Limerick Generating Station, based on 2010 data.
Generating More Low-Carbon Electricity
As part of Exelon 2020, Exelon Nuclear launched a series of planned power uprates across the company's nuclear fleet that will generate additional generating capacity without turning a spade of earth. Uprate projects improve the efficiency and increase electricity output of a nuclear generating unit through upgrades to plant equipment. With approval from the Nuclear Regulatory Commission (NRC), Limerick Generating Station implemented its power uprate project in 2011 and increased its generating capacity by approximately 40 megawatts of electricity, enough to power 40,000 additional homes and businesses.
Limerick employs a sophisticated emergency response plan to protect public health and safety that is approved by the NRC and the Commonwealth of Pennsylvania. The emergency plan includes coordination with local counties, municipalities and school districts.
Our first priority is the health and safety of the public and our employees. Limerick Generating Station has a well-armed and highly-trained paramilitary security force that is routinely drilled and tested. We continue to meet or exceed all security measures mandated by the NRC.
Limerick aims to be a good neighbor and is very active in the local community. Limerick and its employees give generously to the community by providing contributions to local organizations such as:
- Limerick Township Emergency Responders and Parks and Recreation
- Alex's Lemonade Stand Foundation
- Tri-County Peforming Arts Center
- Foundation for Pottstown Education
- Perkiomen Watershed Conservancy
- Schuylkill River Heritage Area
- Limerick Elementary School
- North Coventry Food Pantry
