The following information bulletin is in accordance with Canadian Nuclear Laboratories’ (CNL) ongoing commitment to voluntary public disclosure of events related to the Chalk River Laboratories (CRL).
Chalk River, December 14, 2022 – At approximately 9 a.m. on Sunday, December 11, 2022, CNL was alerted to a fire water line break near Building 212 at the Chalk River Laboratories (CRL) campus. In responding to the incident, personnel discovered an accumulation of water exterior to the building, and its source was traced to a fire water line break.
CNL’s Emergency Operations Centre was activated to manage the incident, the fire water line was taken out of service in order to isolate the break and stop the release of water. Additional measures were taken to ensure fire protection was in place for buildings impacted by the interruption of water service.
Run off from the leak was captured in CRL’s storm water management pond. CNL collected and analyzed a series of water samples taken near the line break and pond, all of which were confirmed to be free of contaminants.
Measures remain in place to ensure fire protection. Repairs to the fire service line are underway and full services will be restored to the affected buildings this week.
CNL can confirm that no employees were injured as a result of this event. CNL can also confirm that there were no off-site consequences to members of the public or the environment, and that conditions on site remain normal. The Canadian Nuclear Safety Commission has been notified about the event.
