Braidwood Clean Energy Center
Limited Capacity
Cost: $65
Braidwood Clean Energy Center's two nuclear reactors can produce up to 2,386 megawatts (MW) of clean, carbon-free energy, enough electricity to power the equivalent of nearly 1.8 million homes. The facility is built on a 4,457-acre site in Braceville, Illinois, and its cooling lake was formed from scarred farming land and an old strip mine.
----- Agenda Overview -----
Guests will arrive at the Pre-Access Facility (PAF), where they’ll be greeted by Constellation personnel and issued visitor badges. From there, the group will be escorted to the Main Access Facility and into the conference area for the day’s activities.
The event will kick off with introductions over lunch, followed by a special presentation from SVP Carolyne Joseph or Plant Manager Hardik Patel, including a live Q&A session. A safety and PPE briefing will prepare guests for the exclusive plant tour.
Guests will then visit the Main Control Room (MCR) for an insider look at operations, followed by an escorted walk-through key area of the plant—including a possible look at Unit 1 and Dry Cask Storage.
The tour will conclude back in the conference room with a final Q&A and wrap-up before departure.
Note: If you have any scheduling conflicts or need to leave early, please notify Sharon Johnson at 630.344.9671 to ensure an escort is arranged.
For all visitors to the site
For those planning to tour the plant RCA
Braidwood Station will provide you with the proper personal protection equipment (hardhats, safety glasses and hearing protection. If you wear hearing aids, please let your escort know so that the appropriate hearing protection can be provided.
Why we need your Social Security or Passport Number
Before being granted access to a nuclear power plant, each prospective visitor’s Social Security or passport number is checked against a national database to ensure the individual has not been denied access at another nuclear site. This is done several days prior to the scheduled visit and again just prior to access authorization on the day of your visit.
We do not retain Social Security or passport numbers once these checks are performed. In addition, those entering the RCA are issued a dosimeter, which measures radiation exposure. While visitors receive very little, if any, radiation exposure during a general tour, your Social Security number is the unique identifier that is used to record the reading on your dosimeter following the tour.
