Port Granby

CNL reports that an early warning system alarm was triggered on Friday, January 13, 2017 in one of the process rooms inside the Port Granby Project Waste Water Treatment Plant. The alarm indicated that elevated levels of hydrogen sulphide gas were present. Hydrogen sulphide is a typical by-product of wastewater collection and treatment processes.

Upon hearing the alarm, all personnel followed procedure and exited the building immediately. As a precaution, two workers sought medical evaluation. Both were cleared to return to work.

There were no off-site effects, and at no point was there a threat to the safety of the public. CNL has proactively notified the Canadian Nuclear Safety Commission of this event.
