As part of our ongoing maintenance program, the Boiler Safety Relief Valves will be tested on Bruce A’s Unit 3 during daytime hours on Tuesday, Oct. 16.

Neighbours may see steam exiting Unit 3 and could hear a low rumble, similar to that of a train. Please be aware this steam contains no radioactive materials and the sound is a normal part of the process.

If you have questions, please contact the Duty Media Officer at 519-361-6161.
