Canadian Nuclear Laboratories (CNL) is Canada's premier nuclear science and technology organization. It is a world leader in developing peaceful and innovative applications of nuclear technology through its expertise in physics, metallurgy, chemistry, biology, and engineering. CNL's operations span a wide range of activities, including research and development, environmental remediation, decommissioning of legacy sites, and the production of medical isotopes. CNL manages and operates Atomic Energy of Canada Limited's (AECL) sites under a Government-Owned, Contractor-Operated (GOCO) model, advancing Canadian interests in nuclear science and technology.
Serves as the primary hub for CNL's advanced research and development, nuclear operations, isotope production, waste management, decommissioning activities, and corporate administration. It houses unique, world-class nuclear research facilities, laboratories, and testing capabilities.
Home to historic nuclear reactors (e.g., NRU, NRX - now in decommissioning), advanced materials research facilities, hot cells for handling radioactive materials, isotope processing facilities, and significant new infrastructure under development like the Advanced Nuclear Materials Research Centre (ANMRC). The site is strategically situated on the banks of the Ottawa River.
A highly specialized, safety-conscious, and research-driven environment. Emphasis on scientific excellence, innovation, collaboration (both internal and external), and stringent adherence to nuclear safety, security, and environmental protocols. Fosters a culture of continuous learning and development for its diverse workforce of scientists, engineers, technicians, and support staff, with a strong sense of national mission and contribution to global science.
Chalk River Laboratories is of immense national and international significance. It has been central to Canada's nuclear program for over 75 years, contributing groundbreaking research to global nuclear science, pioneering reactor technology (including the CANDU design), leading medical isotope production that has benefited millions worldwide, and advancing materials science. It's a key national asset for maintaining Canada's nuclear expertise, supporting clean energy policy, and addressing complex environmental remediation challenges.
CNL maintains a significant global presence through international collaborations with research institutions, governments, and commercial entities. It exports specialized nuclear services, products (like isotopes), and expertise in areas such as CANDU reactor technology, advanced fuel development, materials science, cyber security for nuclear facilities, and waste management solutions. CNL actively participates in international research projects, standard-setting organizations (e.g., IAEA, NEA), and scientific conferences, contributing to global advancements in peaceful nuclear applications, safety, and non-proliferation.
