	Chalk River Laboratories - Wikipedia, the free encyclopedia
		By 1944 the Chalk River Labs were opened and in September, 1945 the facility saw the first nuclear reactor outside of the United States go operational.
		Chalk River Labs are also near the site of Canada's first nuclear power plant, a partnership between AECL and Hydro-Electric Power Commission of Ontario, which went online in 1962.
		Chalk River Labs remain an AECL facility to this day and are used as both a research (in partnership with the NRC) and production facility (on behalf of AECL) in support of other Canadian electrical utilities.

		NRX was an experimental heavy water moderated nuclear reactor at the Canadian Chalk River Laboratory which experienced a partial core meltdown accident on 12 December 1952.
		Two pushbuttons on the main panel in the control room activated magnets to seal the rods to the pneumatic system, and the pushbutton to cause the pneumatic blowdown of the rods into the core was located a few feet away.

	Nuclear Research Establishments (Site not responding. Last check: 2007-10-10)
		Chalk River was the site of Canada's first large research reactor, NRX, a 10 megawatt (MW) facility which used natural uranium fuel and a deuterium moderator.
		Under his direction, the laboratories expanded from a wartime project of 200-300 professional and support staff to a world-class science centre, making important contributions to physics, chemistry, biology, nuclear technology and engineering.
		Devices and techniques developed at Chalk River, such as those for cancer therapy, neutron-activation analysis and radiation measurement, are in use around the world.

	Chalk River Nuclear Laboratories -- A Citizen's Guide
		Chalk River Nuclear Laboratories is a nuclear research and development facility owned by Atomic Energy of Canada Limited (AECL), a federal crown corporation.
		The Chalk River Nuclear Laboratories property is likely the most contaminated piece of land in the country.
		The Chalk River property needs to be cleaned up to protect human health now and in the future, and to restore the environment so that the risks to other species are reduced as well.

	Legion Magazine : Entering The Nuclear Age
		Chalk River Nuclear Laboratories was to host a 20-million-watt reactor called the NRX, for National Research X-Metal (X-Metal being the wartime code for uranium; later the name was changed to National Research Experimental, but it would always be known simply as NRX).
		Canadian research reactors at Chalk River did turn out a relatively small amount of plutonium for the American market until well into the Cold War, but the broader foresight of NRX's designers, and the scientific vision of the National Research Council, put Canada soundly on a path to peaceful nuclear research and development.
		By 1952 the operations at Chalk River had outstripped the NRC's original mandate, and a new crown corporation, Atomic Energy of Canada Ltd., AECL, was created with the sole purpose of pursuing peaceful applications of Canadian nuclear research and development.

	Financial guarantee for decommissioning of the Chalk River Laboratories
		Financial guarantee for decommissioning of the Chalk River Laboratories
		Given the major investment of public funds anticipated for CRL decommissioning, and the uncertainty regarding key issues such the acceptability of and funding for potential "support and enabling facilities" such as the proposed "Shallow Rock Cavity", CCRC strongly feels that a locally-oriented communications and public consultation strategy is unacceptable.
		Ongoing activities at CRL continue to generate wastes, yet the assumption is that these wastes can simply be buried in the waste management areas (WMAs) many of which are leaching radionuclides in an uncontrolled fashion.

	A Look at Deep River, Ontario, Canada
		The nuclear laboratories at Chalk River and the town of Deep River were created in 1944 as a result of Winston Churchill's decision that Canada should be the site of the Commonwealth's contribution to the U.S. Manhattan Project, which produced the atomic bomb.
		Foes of the industry have sometimes claimed that Chalk River produced plutonium for the atomic bombs dropped on Japan, but the truth is that there was no nuclear activity in Chalk River until after the war.
		Although Deep River became independent of Big Brother in 1959, and although the government has gradually divested itself of its holdings in the town (the last of the government-owned houses went on sale to residents in 1984), the recreational "good life" has never abated.

		September 22, 2004 (Update) -- The Canadian Nuclear Safety Commission will conduct a screening commencing on September 13, 2004 of the project: Proposed decommissioning by AECL of a pool test reactor (PTR) at Chalk River Laboratories.
		This low-power (less than 100 W) pool-type reasearch reactor was built at Chalk River in 1957.
		The reactor, which was retired from service in 1990, was used for burnup measurement of fissile samples from NRX.

		This facility, constructed in 1952, was used to process and treat radioactive liquid wastes produced by the NRX fuel reprocessing work conducted between 1952 and 1958.
		Some evaporation activities were also sporadically carried out between 1958 and 1967 to concentrate about 450 cubic metres of stored process wastes remaining from earlier fuel processing.
		Under section 5 of the Canadian Environmental Assessment Act, an EA is required for this project because the Canadian Nuclear Safety Commission may issue a permit or license under subsection 24(2) of the Nuclear Safety and Control Act.

		Because of the unique ways that neutrons interact with the atoms out of which all materials are composed, neutron scattering experiments can often provide materials scientists and engineers with highly effective knowledge that cannot easily be obtained by other methods.
		Researchers and students visit Chalk River to carry out their experiments with the support of experienced staff scientists and technicians.
		The aim will be to engage the interest of workshop participants to consider incorporating neutron scattering as an element in their own research programs.
