Bruce B Update

Bruce B Update:

Updated – March 30, 2020

On March 28, staff at Bruce B responded to a release of approximately 20 litres of heavy water in Unit 6 which has been shut down since Jan. 17 for Major Component Replacement. The spill occurred when crews were flushing a system as part of layup activities for the unit.

Heavy water from the reactor contains levels of tritium, and station staff followed their procedures to promptly stop the spill and safely clean it up, including assembling Bruce B employees away from the affected area while the cleanup occurred. Barriers were established to restrict personnel and tritium levels monitored by station monitoring equipment and staff.

There have been no adverse impacts to our employees, the environment or the public. An investigation to determine the cause of the event is underway and once complete, steps will be taken to implement any lessons learned.
