Policy on Compliance with the Illinois Biometric Information Privacy Act

The Illinois Biometric Information Privacy Act (BIPA) regulates the collection, use, and retention of a person's biometric identifiers or information (biometric data).  It requires collectors of this information to, among other things, establish a retention schedule and guidelines for permanently destroying biometric data when the initial purpose for collecting or obtaining such biometric data has been satisfied or within 3 years of the individual's last interaction with the private entity, whichever occurs first. 

Constellation Energy Generation, LLC (Constellation Generation) is the largest operator of commercial nuclear power plants in the United States.  As part of its extensive efforts to ensure the security of these facilities and to comply with federal government regulations, Constellation Generation collects biometric data in the form of fingerprints and hand geometry scans from persons who apply for and persons who are granted unescorted access to one or more of its nuclear power plants or to Safeguards Information.  The collection of fingerprints for these purposes is required by Section 149 of the Atomic Energy Act of 1954, as amended, and the regulations of the United States Nuclear Regulatory Commission (NRC) at 10 CFR §§ 73.55, 73.56, and 73.57.  Upon collection, Constellation Generation transmits these fingerprint files electronically to the NRC to provide to the Federal Bureau of Investigation for the purpose of conducting criminal history records checks.  The results of the criminal history records checks are provided to and used by Constellation Generation as part of its determination of the trustworthiness and reliability to hold unescorted access or have access to Safeguards Information.  

Fingerprint files collected by Constellation Generation are securely stored and transmitted by Constellation Generation to Government entities using a reasonable standard of care within the nuclear industry. Constellation Generation periodically destroys the fingerprint files it collects once the initial purpose of collection has been satisfied, not to exceed three years.  After the fingerprint files are transmitted to the Government entities, Constellation Generation retains a secure copy of the electronic file for a period of time in case the data becomes corrupted in transmission. The electronic files are periodically deleted based on the date the electronic file was created, but within a three-year period. 

Constellation Generation collects hand geometry scans of persons granted unescorted access for the purpose of verifying the identity of persons who have already been granted unescorted access prior to each entry into the protected area of its nuclear power plants. For Constellation Generation’s Illinois-based nuclear plants, hand geometry data is stored in a secure system and is evaluated, typically every thirty days.  All hand geometry data for persons who no longer require unescorted access to the facility is deleted as part of that evaluation. 

Constellation Generation does not sell, lease, trade, disclose, redisclose, disseminate, or profit from a person’s biometric data.

Additional information regarding the NRC's requirement for access authorization and physical protection of nuclear power plants can be found on the NRC's website at
