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 ...
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 ...
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.
Building reactors in downtown Montreal was out of the question; the Canadians selected, and Groves approved, a site at Chalk River, Ontario, on the south bank of the Ottawa River some 110 miles (180 km) north west of Ottawa. [46] The Chalk River Laboratories opened in 1944, and the Montreal Laboratory was closed in July 1946. [45]
NRX and Zeep buildings, Chalk River Laboratories, 1945. The Ottawa River is behind the reactor buildings. The ZEEP (Zero Energy Experimental Pile) reactor was a nuclear reactor built at the Chalk River Laboratories near Chalk River, Ontario, Canada (which superseded the Montreal Laboratory for nuclear research in Canada). ZEEP first went ...
Charles River Laboratories Intl. Inc (NYSE: CRL ), a preclinical and clinical laboratory service provider to the pharmaceutical , medical device and biotechnology industries, is "by far" an ...
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 NRU reactor at the Chalk River Laboratories due to close in 2016, there was a need to find alternative sources of the medical isotope technetium-99m, a mainstay of nuclear medicine. In 2011 the Canadian Light Source received $14 Million in funding to investigate the feasibility of using an electron LINAC to produce molybdenum-99 , the ...
