At one point, the Chalk River Laboratories produced about one-third of the world's medical isotopes and half of the North American supply. Despite the declaration of peaceful use, from 1955 to 1985, Chalk River facilities supplied about 254.2 kilograms (560 lb) of plutonium , in the form of spent reactor fuel, to the U.S. Department of Energy ...
Historically, the Chalk River Laboratories was a nuclear power plant and advanced nuclear research facility. CNL began developing nuclear technology in the late 1940's and early 1950's . [ 2 ] The government owned company Atomic energy of Canada Limited (AECL) took over Chalk River Nuclear Laboratories in 1952, but today the site remains ...
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. [2] NRU started self-sustained operation (or went "critical") on November 3, 1957, a decade after the NRX, and was ten times more powerful.
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 ...
NRX and Zeep buildings 1945. NRX was for a time the world's most powerful research reactor, vaulting Canada into the forefront of physics research.Emerging from a World War II cooperative effort between Britain, the United States, and Canada, NRX was a multipurpose research reactor used to develop new isotopes, test materials and fuels, and produce neutron radiation beams, that became an ...
With the completion of the NRX reactor in 1947, AECL's Chalk River Laboratories possessed the world's most powerful research reactor. While the large neutron fluxes available in the reactor led to advances in such fields as condensed matter physics and neutron spectroscopy, many experiments were carried out involving the production of new isotopes.

ZED-2 (Zero Energy Deuterium) is a zero-power nuclear research reactor built at the Chalk River Laboratories in Ontario, Canada. It is the successor to the ZEEP reactor. . Designed by AECL for CANDU reactor support, the unit saw first criticality on 7 Septemb
