A nice writeup about research reactors in Canada from CNSC: http://www.nuclearsafety.gc.ca/eng/about/regulated/processing_research/nuclearresearch/index.cfm ... this is the part on NRU: "The Chalk River Laboratories (CRL), owned and operated by Atomic Energy of Canada Limited (AECL) is one of the more complex nuclear sites in the country.
Activities and facilities at CRL encompass non-power reactors, isotope production, fuel fabrication and research, tritium processing, waste management and waste treatment, decommissioning projects, new facilities projects, Class II Nuclear Facilities and numerous radioactive laboratories, in an environment of continuous change to upgrade of decommissioned, aging facilities or construct new facilities.
Decommissioning is currently taking place at Whiteshell Laboratories at Pinawa, Manitoba. AECL's Whiteshell Laboratories have been a major nuclear research facility for more than 35 years, leading the development of dry storage containment facilities for used nuclear fuel, a technology now used around the world. The site has also been home to research in food irradiation, hydrogen safety and performance, materials science for satellites and high performance aircraft, nuclear reactor design, reactor safety and waste management.
The National Research Universal (NRU) reactor at CRL has been a major part of Canadian nuclear research. The NRU produces the majority of the world's medical isotopes used in the diagnosis and treatment of life-threatening diseases. It is also Canada's only major materials and fuel testing reactor used to support and advance the CANDU reactor design. The NRU produces neutrons used by the National Research Council's Neutron Beam Centre to investigate and study all types of industrial and biological materials. Read more about CRL and the NRU.
Also located at CRL, is the ZED-2 research reactor. Marking its 50th anniversary in 2010, the ZED-2 provided AECL with the capability to develop and test fuel bundle designs and fuel arrangements, and to stimulate various incident scenarios. Today, the reactor is still used to conduct testing for improvements to current CANDU reactors and the development of next-generation reactor concepts."
