Strong turnout anticipated for 2022 Open House at Chalk River Laboratories

As CNL and AECL prepare to open their doors to the Chalk River Laboratories for the first time in five years, over 2,700 visitors have already registered to attend the 2022 Open House 

Chalk River, ON – July 25, 2022 – With over 2,700 people already registered to visit Canada’s national nuclear laboratories on Saturday, August 6, Atomic Energy of Canada Limited (AECL) and Canadian Nuclear Laboratories (CNL) are anticipating a strong turnout for the 2022 Open House at Chalk River Laboratories. Last held five years ago, the special event is being organized to celebrate the continued revitalization of the Chalk River campus, AECL’s 70th anniversary, and all the great accomplishments being made by AECL and CNL’s respective teams.

With the event just a few short weeks away, AECL and CNL are now finalizing details for what they hope will be a fun-filled and interactive day for visitors. In addition to over 50 informative booths and displays, hands-on experiments, demonstrations and tours, the Open House will feature family-friendly entertainment for kids and adults alike, including mega-machines, bouncy castles, a nerf gun challenge, decommissioning robots, food vendors, and a whole lot more.

“Public reception to the 2022 Open House has been extremely positive so far, and we are on pace to exceed registration numbers compared to previous events,” commented Joe McBrearty, CNL’s President and CEO. “Employees at both AECL and CNL are working really hard to ensure that we give our visitors a fun, interactive and engaging event. But it is also our hope that the public walks with away with a better understanding of the work that goes here at Chalk River Laboratories, whether it is research related to clean energy, health sciences or environmental remediation.”

In addition to the family-friendly entertainment, which includes the free watermelon and cake that has become one of the biggest draws at the Open House, visitors will also have the opportunity to tour some of the new buildings and laboratories that have been constructed as part of the site revitalization program. CNL will also be conducting a series of presentations discussing some of their exciting new research projects and programs, with topics that include small modular reactors (SMRs), a rare new medical isotope known as Actinium-225, hydrogen energy, and work to establish a new clean energy research park at Chalk River Laboratories.

“The 2022 Open House comes during a particularly exciting period of renewal for the Chalk River Laboratories that includes new buildings and facilities, but which also extends to our science and technology programs,” adds McBrearty. “So, there will be a lot to see and experience if you are interested in what goes on here in Chalk River at the end of Plant Road.”
