Event Notification Report for April 08, 2025

CONCURRENT REPORT - OFFSITE NOTIFICATION DUE TO NON-RADIOLOGICAL MEDICAL TRANSPORT

The following information was provided by the licensee via phone and email:

"At approximately 0015 EDT on April 1, 2025, while exiting from an adjacent work area, an electrician was sprayed with ammoniated water from a leaking hose on a chiller unit. The employee proceeded to a nearby safety shower and rinsed for twenty minutes. Columbia Fuel Fabrication Facility (CFFF) emergency brigade medical first responders provided initial medical treatment. Subsequently, the employee was transported by ambulance to an offsite medical facility and was admitted for further evaluation.

"The emergency brigade performed cleanup of the ammoniated water leak and engineering calculations confirmed that the leak contained less than a reportable quantity of ammonia. A courtesy notification was made to the South Carolina Department of Environmental Services in accordance with established communications protocols.

"The event did not involve special nuclear material or radioactive contamination. The issue has been entered into the corrective action program and the chiller unit will remain down pending further investigation. The CA-134 restart process, [a corrective action protocol], will be followed to ensure appropriate event investigation and recovery actions.

"This concurrent report is being made in accordance 10 CFR 70 Appendix A(c) because a 24-hour report was made to the South Carolina Department of Labor (SCDOL) per 29 CFR 1904.39(a)(2). SCDOL was notified of the incident and in-patient hospitalization of the employee at 1518 EDT on April 1, 2025."
