If you haven’t heard, we had over 3,000 visitors attend the 2022 Open House at Chalk River Laboratories last weekend – a record turnout! Some of our photos are starting to come in, and we wanted to share a few early shots of the event with you. Needless to say, we truly appreciate everyone who took the time to come out and learn about our work. We would not be able to do what we do without the support of our local communities. #grateful

And stay tuned for photos from the big day!

Comment on Facebook

Any chance the people who were demonstrating the equipment & managing the displays/posters could be asked to provide comments on each of the pictures provided that relate to their work. I was unable to attend this year.

CNL’s decommissioning team has begun a new project in the attic of one of the old buildings that will be safely decommissioned at Chalk River Laboratories. This building houses various laboratories, glove boxes, fume hoods and hot cells that were all historically used to conduct radiological research and experiments.

The building’s attic houses an intricately designed custom ventilation system comprising of over 10 large exhaust fans encased in metal ductwork. These fans were what maintained radiological contamination control in the building, and the interior components and panels could have radiological and non-radiological contamination as a result.

In order to dismantle and remove the exhaust fan system as part of decommissioning activities, the team needs to verify the presence or absence of radiological contamination and any other potential hazards to develop work plans. A project to sample strategic locations on the interior surfaces of the exhaust fans began in the early spring.

As part of sampling activities, Temporary Enclosures were built around the sampling areas of the exhaust fans and staff donned the required Personal Protective Equipment and Clothing during the field work. Radiological Continuous Air Monitoring equipment was also placed in the work area.

The exhaust fans were also safely placed in a de-energized state while any sampling work was conducted. While the exhaust fans no longer support active work, they do still ventilate the fume hoods in the building due to the presence of legacy contamination. CNL staff ensure that proper controls are in place when shutting down any exhaust fans and before returning them to service.

The team will continue to sample all of the exhaust fans in the building and the results will guide future characterization activities and work plans to safely dismantle the ventilation system.
