National Research Universal Reactor
Coordinates: 46°3′15.53″N 77°21′52.12″W / 46.0543139°N 77.3644778°W The National Research Universal (NRU) reactor is a 135 MWt nuclear research reactor built in the Chalk River Laboratories, Ontario, one of Canada’s national science facilities. It is a multipurpose science facility that serves three main roles. It generates isotopes used to treat or diagnose over 20 million people in 80 countries every year (and, to a lesser extent, other isotopes used for non-medical purposes). It is the neutron source for the NRC Canadian Neutron Beam Centre: a materials research centre that grew from the Nobel Prize-winning work of Bertram Brockhouse. It is the test bed for Atomic Energy of Canada Limited to develop fuels and materials for the CANDU reactor.
The NRU reactor design was started in 1949, and is fundamentally a Canadian design, significantly advanced from NRX. It was built as the successor to the NRX reactor at the Atomic Energy Project of the National Research Council of Canada at Chalk River Laboratories. The NRX reactor was the world's most intense source of neutrons when it started operation in 1947 and had attracted a large scientific community who were using those neutrons in research that was then possible for the first time. It was not known how long a research reactor could be expected to operate so the management of Chalk River Laboratories began planning the NRU reactor to ensure continuity of the research programs.
