AECL (Canada)

AECL Nuclear Laboratories

Mr. A.J. White, GM, Programs and Nuclear Oversight, Chief Regulatory Officer, Atomic Energy of Canada Ltd, Chalk River Laboratories, Chalk River, Ontario, Canada, K0J 1J0

Canadian Nuclear Safety Commission (CNSC), 280 Slater Street, Ottawa ON, Canada

Atomic Energy of Canada Limited (AECL) is Canada’s premier nuclear science and technology organization. It is a strategic element of both Canada’s national science and technology infrastructure and its national innovation system.  AECL has unique capabilities of working with radioactive materials, under license from the federal regulator, that have application in fields important to public policy and to the
nuclear sector domestically and internationally. Its public policy role includes:
conducting nuclear research and development, producing medical isotopes, and managing legacy and historic nuclear wastes.
Output Program Activities:
1. Nuclear Industry Capability: The Canadian nuclear sector remains safe and productive with access to S&T resources to address emergent technological challenges.
2. Nuclear Safety and Security: Canada’s nuclear safety and security is assured, based on high quality expertise and technology.
3. Clean, Safe Energy: Development of energy technologies that make a beneficial impact on Canada’s use of clean energy.
4. Health, Isotopes and Radiation: Canadians experience health benefits from nuclear Science and Technology.
5. Nuclear Environmental Stewardship: Nuclear sites are clean and healthy environments.
6. Nuclear Innovation Networks: Canadian Science and Technology communities advance their innovation agendas through access to federal nuclear innovation infrastructure and expertise.
Enabling Program Activities:
7. Mission-Ready Science and Technology Infrastructure: Ensuring that the science and technology infrastructure is ready to enable the six (6) outcome Program Activities by investing in people, plant and processes to achieve safe and efficient execution.
8. Internal Services: The suite of business support services that is common across the Program Activity Architectures of all federal departments and agencies.
This TSO participates in many international forums including the IAEA and NEA.  We also have bilateral agreements with many countries around the world covering various focus areas for which we provide expertise.
GRS (Germany)
Schwertnergasse 1, D-50667 Cologne, Germany
The Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) is a non-profit organisation which deals with technical-scientific research and provides expertise. The company administers interdisciplinary knowledge, progressive methods and qualified data.
GRS was established in January 1977. The headquarters are in Cologne, other sites include: Berlin, Braunschweig and Garching nearby Munich. Currently, there are approximately 450 employees at GRS, 350 of whom work in the technical-scientific sector. GRS is only financed by contracts and the present annual volume of contracts is worth 57 million €.
GRS’s main customers are:
• The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. (BMU)
• The Federal Ministry for Economics and Technology. (BMWi)
• The Federal Ministry for Education and Research. (BMBF)
• The Department for Foreign Affairs
• The Federal Agency for Radiation Protection (BfS)
Furthermore, GRS works on contracts from the Federal State Authority, the Federal Environmental Agency and the Technical Supervisory Board. An important international customer is the European Commission.
The aim of the international co-operation of GRS is to contribute to the highest possible safety of nuclear installations worldwide. This is achieved on the one hand by participating in working groups (e.g. of the IAEA or the OECD/NEA) and on the other hand by networking. This is to ensure a constant exchange of information about the development of new methods and the advancement of the state of the art in science and technology. The most important networks and initiatives of GRS are ETSON (European Technical Safety Organisation Network) and EUROSAFE.
