reactor first went critical, achieving the first "self-sustained nuclear reaction outside the United States". ZEEP put Canada at the forefront of nuclear research in the world and was the instigator behind eventual development of the CANDU reactors, ZEEP having operated as a research reactor until the early 1970s. In 1946 the Montreal research laboratory was closed and research was consolidated at Chalk River Laboratories. On July 22, 1947, the NRX (National Research Experimental) reactor, the most powerful reactor in the world at the time, went critical and was "used successfully for producing radioisotopes, undertaking fuels and materials development work for CANDU reactors, and providing neutrons for physics experiments".


1950s

In 1952 AECL was formed by the government with a mandate to develop peaceful uses of nuclear energy. On December 12, 1952, one of the world's first major reactor accidents occurred in the NRX reactor at AECL's Chalk River Laboratories, when a combination of human and mechanical error led to a temporary loss of control over the reactor's power level. Undercooling of the fuel channels led to a partial

. This caused a hydrogen-oxygen explosion inside the calandria. Several fuel bundles experienced melting and ruptured, rendering much of the core interior unusable. The reactor building was contaminated, as well as an area of the Chalk River site, and millions of gallons of radioactive water accumulated in the reactor basement. This water was pumped to a waste management area of the Laboratories and monitored. Hundreds of military personnel from Canada and the U.S. (including naval officer and later U.S. President, LT James "Jimmy" Carter) were employed in the cleanup and disposal of the reactor debri

The NRX was repaired, upgraded, and returned to service 14 months later and operated for another 40 years, finally being shut down in 1992. Throughout the 1950s the NRX was used by many researchers in the pioneering fields of

) first went critical. This was a natural-uranium fuelled, heavy-water moderated and cooled research reactor (converted to high-enriched-uranium fuel in the 1960s, and finally to low-enriched-uranium fuel in the 1990s). The NRU is a world-renowned research facility, producing about 60% of the world's supply of molybdenum-99, the principle isotope used for nuclear medical diagnosis. Canada also pioneered use of cobalt-60 for medical diagnosis in 1951 and currently the NRU reactor produces the medical-use cobalt-60, while selected CANDU reactors produce industrial-use cobalt-60, comprising 85% of the world's supply. NRU was primarily a Canadian design, and a significant improvement on NRX. Other than radioisotope production, the NRU provides irradiation services for nuclear materials and fuels testing, as well as producing neutron beams for the National Research Council's Canadian Neutron Beam Laboratory. On May 24, 1958, the NRU suffered a major accident. A damaged uranium fuel rod caught fire and was torn in two as it was being removed from the core, due to inadequate cooling. The fire was extinguished, but not before releasing a sizeable quantity of radioactive combustion products that contaminated the interior of the reactor building and, to a lesser degree, an area of the surrounding laboratory site. Over 600 people were employed in the clean-u

1970s

In 1971 the first commercial CANDU reactor, Pickering A 1, began commercial operation. By 1973 the other three reactors of the A group at Pickering were online and constituted the most powerful nuclear facility in the world at that time. Each Pickering unit produces about 600 MWe of power. On May 18, 1974,

1980s

Between 1983 and 1986, the Pickering B group went online and also in 1983 the single CANDU reactor at Point Lepreau began operation, as did the Gentilly 2 CANDU reactor. Between 1984 and 1987 the Bruce B group began commercial operation, and also in 1987 the CANDU design was ranked one of Canada's top-10 engineering achievements.

The Ontario government has since suspended the acquisition process citing the cost and uncertainty surrounding the companies future ownership (discussed below). Medical isotope production using the 1957-built NRU reactor experienced two forced outages due to safety concerns (December 2007) and a heavy water leak (May 14, 2009). The production from the NRU reactor represented a significant fraction of the worlds medical isotope supply and the disruptions caused a worldwide shortage. Due to maintenance requirements from the aging NRU reactor and the failure of the MAPLE 1 & 2 reactor projects, the long term production of medical isotopes at Chalk River became uncertain. The NRU reactor at Chalk River was shut down in 2018.

won an international bidding process for the reactor design division of the company. Prior to the acquisition, of SNC Lavalin's international power workforce (400 of 4000) were engaged in the production and refurbishment of nuclear reactors. Concerns raised about the deal include a lack of commitment by SNC-Lavalin to keeping the design division intact (its size makes it more capable of providing ongoing safety support). For 2010 and 2009 combined Atomic Energy of Canada Ltd lost million. Following divestiture of the reactor design division, AECL will consist of the current Nuclear Laboratories division, including the Chalk River laboratory (produces isotopes for medical imaging), and will continue to be a Crown Corporation on paper but will privatise the operation of its facilities.
