Nuclear power is not clean energy! It's the most expensive form of power generation! They are currently asking to increase electricity prices in Ontario! The 10 thousand year half life, is a major problem . To say we are going to bury it is not a real solution, Chernoble is leaking Fukushima is leaking! Green energy is a third of the cost of one nuclear power plant! We could put solar and wind on every building and house in Ontario for a third of the cost of one nuclear power plant! A one time payout would give us 20 to 25 years of free power! We already spend 20 billion a year for security at these plants! The choice is simple pay ever increasing electricity bills or none! It's our money ,the fact that Doug Ford has said we will be buying power is a con ! We sell electricity to wholesalers in the United States and they sell it back too us at an increased rate!
Every year, we proudly celebrate #NuclearScienceWeek. As Canada’s national nuclear laboratory, it’s an excellent opportunity for us to spotlight the important role nuclear science plays in our world, from energy production to medicine, security, and environmental stewardship.
Next week, we’re turning up the energy with a full lineup of great events, from community programming at local libraries and events to radio competitions and staff events. It’s all about education, innovation, and inspiration, and we invite you to celebrate with us.
Come grab a free small coffee, tea, or bubble tea on us while you learn about nuclear this week at Sip Stirs, Pembroke.
You can also join us at our special nuclear exhibit, “Science and Sip,” on October 24 at Sip Stirs in Pembroke from 5:30–8:00 p.m.
And if you're in Renfrew County, tune in to MyFM Hustle & Heart 96.1 myFM to play special #NSW trivia games and win some prizes!
It’s a fantastic week to discover more about nuclear science!

We pulled aside five of our scientists to debrief after presenting at the international Nuclear Materials Conference (NuMat 2026) a few weeks ago in Halifax, Nova Scotia! 🎤
Focused on nuclear materials science, NuMat brings together international experts from national labs, utilities, regulators, universities, and the broader nuclear industry every two years. Since the conference’s inception in 2010, this is the first year it was hosted in Canada — and CNL was proud to sponsor and contribute to the programming with eight presentations and four posters.
Thank you to Elsevier and the International Atomic Energy Agency (IAEA) for such a great conference! ... See MoreSee Less

This is great, love to see scientists from CNL showcasing their research. Well done team!
A historic chapter is coming to a close at Chalk River Laboratories.
Our decommissioning team has officially begun its 133rd demolition project!
Built between 1950 and 1953, Building 250, the former Chemical Engineering and Materials Testing Facility, played an important role in Canada's early nuclear research program. For decades, the facility supported specialized laboratory and testing activities that helped advance nuclear science and engineering across the country.
Reaching this milestone has taken years of preparation. Over the past seven years, hundreds of workers, technical specialists and support staff have safely removed hazards, reduced environmental liabilities and prepared the building for demolition.
Demolition activities will continue through spring 2027. When complete, more than 13,500 square feet of building footprint will have been safely removed, representing another significant step toward transforming Chalk River Laboratories for the future. ... See MoreSee Less

That much asbestos, huh?
Started the paperwork for the demolition in 1954😆
Who’s doing a teardown contractors or Cnl employees 
Our decommissioning team ?
That is one heavy excavator
I worked in that building 1968-1970, Applied Materials Research Branch. Eric LeSurf was my boss. Roy Thomas was the branch head.
Last night when I was walking out, I saw my old office being torn out. Definitely brings back memories.
Kimberly Wolfgram Schmidt, does this affect your building & office?
Prime seats in ACB to watch it come down!
A lot of great research was performed in that building. It has an amazing history! Spent the early days of my career in that building.
So sad but understandable. I was fortunate to work there as a summer student in 1994-95 and 1995-96. My dad also worked in that building.
My father and I both worked in that building when I was a university student back in 1983 and 1984.
Peter Poruks your old home! Think of all the good times you had sitting across from Sterling!
Great building to work in...5 years there..
Brings back so many memories! 1975-2009
Congratulations to everyone who contributed to getting to this point in the process. Massive undertaking 👏
I'm honestly impressed we got here this fast! I started my career in that building and made lots of great memories in there. Worked with lots of brilliant, hard-working people who remain good friends to this day.
I look forward to another open house tour should it happen. I'm sure I will not recognize the place.
Many memories, great friends, and coworkers. 1988+. Sad to see it finally go.
Mark McKenna I never thought we’d see the day. 😮
Great to see this finally coming to fruition!
Well there goes the Bldg. 250 gymnasium & weight room? Lot of memories spent there??
Lots of memories for me as well. Sad to see it finally being taken down. Worked with so many great people in that building
I transported flasks to 375 also Trit to Montreal Airport many times
Worked in that building from 1988-2018. Lots of memories.

CNL has applied to the Canadian Nuclear Safety Commission (CNSC) to renew our decommissioning licence for the Whiteshell Laboratories site enabling us to progress with site restoration.

Just leave it open and keep the community employed!
Remember when we visited the research forest that was on this site!
Recommisioned? I thought it was being closed .👀🎱🫤🤔
I heard WR1 wasn't decommissioned as per the original plan.
Our governments are currently seeking to increase the future, in 2004 I was paid by the federal government to make recommendations on the future use of nuclear power! Myself and a large majority of people after receiving all possible information we said it was not the direction we should go! The 10 year half life of the waste was the most dominant reason! If you tell me they will put it a valt remember that Chernoble is leaking and Fukushima is leaking! We in Ontario already sell electricity to 22 million homes and businesses in the United States! There's only 16 million people in Ontario! So why do we want to as Ontario taxpayers need to pay hundreds of billions of dollars for more power, the ceo of OPG makes 30 million a year!
Nuclear power is the biggest problem we have!
Have any meaningful goals been accomplished in the decommissioning ? There seems to be alot of construction going on for a facility deing decommmissioned.
