Atomic Energy of Canada Limited


Joint statement from AECL, CNL & the Town of Deep River

Chalk River, ON – April 05, 2021 – Atomic Energy of Canada Limited (AECL), Canadian Nuclear Laboratories (CNL) and the Town of Deep River issued the following joint statement today:

In response to the ongoing revitalization of the Chalk River Laboratories campus, including the decommissioning of aging infrastructure and new capital investments, AECL, CNL and the Town of Deep River have agreed to an examination of recent assessments of property value for some of the buildings at the AECL-owned site.

The objective of this evaluation is to provide for a fair valuation of new and renovated facilities at the Chalk River Laboratories’ facilities, as the foundation for updating the payment in lieu of property taxes. The three parties will work together with the Municipal Property Assessment Corporation to review assessments.

“As the company contracted to operate AECL’s Chalk River Laboratories campus, CNL is pleased to participate in this process and will work collaboratively to support this review,” commented Joe McBrearty. “All three parties recognize just how important it is that these payments reflect the proper value of the site, and I’m pleased that we were able to proactively come to an agreed path forward on this assessment.”

“AECL is making significant investments in the Chalk River Laboratories to transform it into a modern, world-class nuclear science and technology campus.” Fred Dermarkar added, “As we modernize our facilities, it is important that this be reflected in our contributions to the local communities through payments in lieu of taxes. We are proud of our history in this strong and vibrant local community, and want to see this continue for decades to come.

“On behalf of the Town of Deep River, I want to express our appreciation to AECL and CNL for the open, professional and constructive dialogue they have engaged in with us.  As a conscientious corporate citizen, they volunteered to have the recent new construction at Chalk River Laboratories reassessed to ensure fairness in taxation, despite the fact that they are not legislatively obliged to do so.  AECL, CNL and CNEA are exceptional members of our community and have partnered with us on many recent initiatives including: fire services, water and improvements to internet.  We are fortunate to have them as part of our town.” Sue D’Eon, Mayor

Canada, United States, Announce Completion of Nuclear Material Shipping Project

Atomic Energy of Canada Limited (AECL) and the United States Department of Energy’s National Nuclear Security Administration (DOE/NNSA) today announced the completion of a multi-year project to repatriate highly enriched uranium (HEU) liquid target residue material from the Chalk River Laboratories in Ontario, Canada to the Savannah River Site in Aiken, South Carolina.   

The material was the by-product of the production of medical isotopes from AECL’s National Research Universal reactor. While the research reactor is now shutdown, for many decades it produced medical isotopes used for the treatment and diagnosis of cancer and other diseases. Over the years, this benefited billions of people in Canada and around the world. The medical isotopes were produced using HEU supplied by the United States.   

The shipping project, which began in 2017 and finished in August of 2020, involved 115 separate truck shipments, resulting in the return of more than 161 kilograms of HEU. Over the four-years of the campaign, the shipments covered more than 240,000 kilometers of safe and secure transportation, equivalent to traveling around the earth six times.    

Together, the completion of this shipping campaign, along with the recently completed campaign of spent nuclear fuel from the National Research Universal and National Research Experimental research reactors, resulted in the repatriation of more than 367 kilograms of HEU.  

This not only reduces Canada’s environmental liabilities and risks, it also serves our nuclear security and non-proliferation objectives by reducing the availability of this material.  

The target residue material was returned to the United States under the U.S.-Origin Foreign Research Reactor Spent Nuclear Fuel Acceptance Program, which was established in 1996 with the mission to repatriate U.S.-origin spent nuclear fuel and other weapons-grade nuclear material from civilian sites worldwide.  

Canadian Nuclear Laboratories, the United States Department of Energy’s Office of Environmental Management, Savannah River Nuclear Solutions and Savannah River National Laboratory were key partners and played a pivotal role in the success of the campaign. AECL and DOE/NNSA continue to explore the repatriation of additional highly enriched uranium and other materials over the next several years.

Fred Dermarkar to Assume the Position of President and CEO of AECL

The Government of Canada has appointed Fred Dermarkar to take over as President and Chief Executive Officer (CEO) of Atomic Energy of Canada Limited (AECL) effective February 7, 2021.

Fred will replace Richard Sexton, who will retire after 38 years in the industry when his mandate ends in February. Richard has served as AECL’s President and CEO since February 2018, and was interim President and CEO and Acting Chief Transition Officer of AECL for almost two years prior to that.

“I would like to thank Richard for his service to AECL over the past five years. He has played an integral role in establishing AECL as a strong oversight organization and in advancing AECL’s nuclear science and environmental remediation mandates”, said James Burpee, Chair of the Board of AECL.

“It has been an honour to be part of the renewal of nuclear research and development in Canada at a time when nuclear energy is recognized as an important part of Canada’s low-carbon energy goals”, said Richard Sexton.

Fred Dermarkar will join AECL following close to seven years as the President and CEO of the CANDU Owners Group (COG). Prior to that, he held a variety of technical and executive positions at Ontario Power Generation (OPG), and has 40 years experience in the Canadian nuclear sector. “As countries around the world consider the importance of nuclear energy as part of a clean energy mix, AECL has an important role to play in seeing that Canada remains at the forefront of nuclear innovation. I am excited to contribute to AECL’s success in that area and to advance AECL’s environmental remediation mandate”, said Fred Dermarkar.

As a federal Crown corporation, AECL’s mandate is to enable nuclear science and technology and to protect the environment by fulfilling the Government of Canada’s radioactive waste and decommissioning responsibilities.
