On May 6, Bruce A staff discovered a small amount of water from the heat transport system (approximately 200 millilitres, which is less than a pop can) on the floor of Unit 3.
Tritium was detected in the area and station staff followed procedures to allow for safe clean-up, including assembling of Bruce A employees away from the affected area. Unit 3 is currently shut down for planned maintenance and there have been no adverse impacts to our employees, the environment or the public.
An investigation is underway to determine the cause of the event.
