For Immediate Release December 14, 2006

Toronto and Calgary­Nuclear power offers no solution to the climate change crisis. That is the conclusion of a major study of the environmental impacts, risks and sustainability of nuclear energy in Canada published today by the Pembina Institute.

Nuclear Power in Canada: An Examination of Risks, Impacts and Sustainability finds that nuclear power, like other non-renewable energy sources, is associated with severe environmental impacts. These impacts include:

The generation of large amounts of radioactive and hazardous wastes at each stage of the nuclear energy production process. These wastes will require care over thousands of years for safety, health, environmental and security reasons.

Severe impacts on surface and groundwater water quality through the discharge of radioactive and toxic pollutants. Effluent from uranium mines and mills has been found by Health Canada and Environment Canada to be a “toxic” substance for the purposes of the Canadian Environmental Protection Act.

Releases to the air of smog and acid rain causing, radioactive and hazardous pollutants in addition to greenhouse gases.

The report concludes that no other energy source combines the generation of as wide a range of conventional pollutants and waste streams ­ including heavy metals, smog- and acid-rain-precursors and greenhouse gases ­ with the generation of large volumes of radioactive wastes that will require care and management over hundreds of thousands of years.

“These environmental challenges, along with security, accident and weapons proliferation risks that are not shared by any other energy source, place nuclear energy in a unique category relative to all other energy supply options” said Dr. Mark Winfield, Director of the Pembina Institute’s Environmental Governance Program and lead author of the study.

The study finds that nuclear energy production faces additional challenges as a long-term energy supply, including a limited fuel supply and a dramatic increase in fuel prices. World prices for uranium, the fuel source for nuclear energy, have increased more than sixfold since 2001.

The report concludes that in the context of these impacts and risks, nuclear energy cannot be seen as a viable response to greenhouse gas (GHG) emission problems associated with the reliance on fossil fuels (e.g., coal) for electricity generation.

“In addition to the fact that nuclear power is not itself a GHG emission free energy source, a future path based on nuclear energy would simply replace one problem with a series of different, but equally unacceptable impacts and risks. These encompass everything from facility reliability and waste management to the potential for catastrophic accidents and nuclear weapons proliferation,” said Dr. Winfield.

“Energy efficiency and low-impact renewable energy sources offer far safer, cheaper, more reliable and more sustainable options for meeting society’s energy needs, and should be the focus of our future energy policies,” concluded Dr. Marlo Raynolds, the Pembina Institute’s Executive Director.

Background Information

Nuclear Power in Canada: Key Environmental Impacts

Solid and Liquid Wastes

Uranium mining and milling

An estimated 575,000 tonnes of tailings per year, of which 90–100,000 tonnes can be attributed to uranium production for domestic energy purposes. Uranium mill tailings are acidic or potentially acid generating, and contain a range of long-lived radionuclides, heavy metals and other contaminants. Tailings generation would increase proportionally with the use of lower grade uranium ores, as larger amounts of ore would have to be processed to produce the same amount of uranium concentrate.

Up to 18 million tonnes of waste rock, which may also contain radionuclides, heavy metals, and be acid generating. Of this total, up to 2.9 million tonnes can be attributed to uranium mining for domestic energy purposes.

It is estimated that there are more than 213 million tonnes of uranium mine tailings in storage facilities in Canada, and 109 million tonnes of waste rock.

Refining and conversion operations

It is estimated that nearly 1,000 tonnes of solid wastes and 9,000 m3 of liquid wastes are produced per year as a result of uranium refining, conversion and fuel production for domestic energy generation purposes. Information on the precise character and fate of these wastes could not be obtained.

Power plant operation

Approximately 85,000 waste fuel bundles are generated by Canadian nuclear reactors each year. As of 2003, 1.7 million bundles were in storage at reactor sites. It is estimated that these wastes will have to be secured for approximately one million years for safety, environmental and security reasons.

Approximately 6,000 tonnes of lower level radioactive wastes are generated each year in Ontario as a result of power plant operations, maintenance, and refurbishment.

Power plant maintenance and refurbishment also result in the generation of substantial amounts of additional hazardous wastes, including heavy metals and asbestos.

Very large amounts of low, intermediate and high-level radioactive wastes will be produced as a result of the eventual decommissioning of refining, conversion and fabrication facilities as well as power plants.

Water

Severe contamination of surface water and groundwater with radionuclides, heavy metals and other pollutants has arisen from uranium mine tailing management facilities and mine and mill operations.

Discharges to surface waters from uranium mines and mills in Canada in 2003 included over 1,500 kg of uranium, 860 kg of molybdenum, 70 kg of arsenic, 185 kg of nickel, 40 kg of selenium, and 10 tonnes of ammonia.

Effluent from uranium mines and mills was found by Health Canada and Environment Canada to be ‘toxic’ for the purposes of the Canadian Environmental Protection Act in 2004.

Routine and accidental releases of radionuclides to surface waters occur in the course of power plant operations, with tritium oxide and carbon-14 being key radioactive pollutants of concern. Groundwater contamination with tritium has occurred at the Pickering generating facility in Ontario.

Ontario’s nuclear power plants are found to be the leading source of discharges of hydrazine, an extremely hazardous pollutant, to surface waters in Canada. Nuclear generating facilities have also been sources of discharges of metals (copper, zinc, and chromium) and ammonia to surface waters.

Nuclear power is a major consumer of water. Uranium mining operations involve extensive dewatering, in the range of at least 16–17 billion litres per year, with the implication of impacts on groundwater and surface water storage and flows.

Generating facilities require large amounts of cooling water. The Darlington and Pickering facilities in Ontario are alone estimated to use approximately 8.9 trillion litres of water for cooling purposes per year ­ more than 19 times the annual water consumption of the City of Toronto.

Adverse thermal impacts of cooling water discharges on fish populations in the vicinity of nuclear power plants have been observed.

Air

Atmospheric releases of a range of radionuclides occur at all stages of nuclear power production. Atmospheric releases of radon gas result from mining and milling operations and from tailings management facilities. Windblown dust from mine sites and tailings management facilities (TMFs) contains a range of radionuclides. Atmospheric releases (principally uranium) also arise from refining and conversion activities.

Routine and accidental releases of radiation and radionuclides occur from power plant operations, including tritium oxide, carbon-14, noble gases, iodine-131, radioactive particulate and elemental tritium.

The incineration of low and intermediate-level radioactive wastes from power plant operations and maintenance in Ontario has resulted in further atmospheric releases of radionuclides, particularly tritium. A wide range of hazardous air pollutants have been released by the Bruce Western Waste Management facility. A new incinerator installed in 2003, has reduced emissions of hazardous, but not of radiological, pollutants
Windblown dust from mine sites and TMFs contains a range of heavy metals. In addition, releases of a number of hazardous air pollutants, including dioxins and furans, hexachlorobenzene, heavy metals (principally lead) ammonia and hydrogen fluoride arise from uranium refining and conversion operations.

Ontario nuclear power plants are the only National Pollutant Release Inventory reported source of releases of hydrazine to the air in Canada.

Uranium mining and milling operations are found to be significant sources of releases of sulphur dioxide (SO2), volatile organic compounds (VOCs) and nitrogen oxides (NOx). Releases of NOx, particulate matter (PM) and sulphuric acid arise from refining and conversion activities.

The road transportation of uranium from mill sites in northern Saskatchewan to the Blind River refinery in Northern Ontario and then on to the Port Hope conversion facility in Southern Ontario produces additional releases of NOx and PM. Further transportation related releases of criteria air pollutants would arise from the long-term management of waste nuclear fuel and other radioactive wastes arising from facility operations, maintenance and decommissioning, particularly if the management strategies for these materials require the movement of wastes from reactor sites to centralized facilities.

Climate

Total greenhouse gas (GHG) emissions associated with uranium mining, milling, refining, conversion and fuel fabrication in Canada are estimated at between 240,000 and 366,000 tonnes of CO2 per year.

Total emissions associated with the sector, including the emissions associated with power plant construction, are in the range of 468,000 and 594,000 tonnes of CO2 per year, equivalent to the emissions of between 134,000 and 170,000 cars per year.

Total annual GHG emissions associated with domestic power production alone are estimated at between 267,000 and 289,000 tonnes of CO2 per year. Other recent estimates suggest total GHG emissions associated with nuclear power in Canada are in the range of at least 840,000 tonnes per year.

MEDIA RELEASE

For Immediate Release December 19, 2006

Inquiry launched into Canadian nuclear advertising

TORONTO – An application was filed today for an inquiry by Canada's Competition Bureau into the Canadian Nuclear Association’s (CNA) high profile advertising campaign touting the benefits of nuclear power. The applicants – including religious, public health, renewable energy and environmental groups from across Canada – allege in the application that claims made in a series of high-profile television, radio and print ads promoting nuclear energy are misleading.

The CNA advertising campaign states, against a background of blue sky, that nuclear power is “clean”, “reliable” and “affordable,” and that nuclear power generation “does not create greenhouse gases,” “keeps the air clean” and is subject to “stable” fuel prices. The application asks the ompetition Commissioner to investigate whether these representations are factually correct and whether individually and as a whole, they create a misleading impression of the environmental impacts and economic costs associated with nuclear power.

“The application calls on the Competition Bureau to clear the air and determine whether the Competition Act has been breached,” said Sierra Legal lawyer Hugh Wilkins. “Conservation and renewable energy initiatives should be ensured a level competitive playing field with nuclear and the public must be allowed to assess the full environmental, health and economic risks and costs of the various energy options available.”

A recently published Pembina Institute report, Nuclear Power in Canada: An Examination of Risks, Impacts and Sustainability, was filed in support of the application. The report documents that electricity generation from nuclear in Canada has created massive volumes of radioactive and hazardous wastes that will require virtually perpetual care, involves the ongoing discharge of a wide range of radioactive and toxic pollutants to air and water, and emits greenhouse gases throughout the full technology lifecycle.

Regarding reliability and affordability claims, the report demonstrates that nuclear power generating facilities in Canada have a history of poor reliability and that facility construction and refurbishment projects in Canada have been subject to major cost overruns. Nuclear plant construction projects in Ontario, for example, have run 40 to 270 per cent over their initial projected capital costs and world uranium prices have increased by a factor of more than six since 2001.

“An energy source associated with water pollution that has been found to be a ‘toxic’ substance as defined under the Canadian Environmental Protection Act should not be described as ‘clean’,” said Dr. Mark Winfield, author of the Pembina Institute report, and one of the signatories to the complaint.

“When asked, people prefer renewable energy to radioactive nuclear power. Our concern is that the nuclear industry’s advertising budget and approach distorts objective decisions which have to be made right now about the future direction of Ontario’s electricity system,” says Julia Langer of WWF-Canada.

The application was filed by Sierra Legal on behalf of representatives from the Pembina Institute, WWFCanada, Ontario Sustainable Energy Association, Sky Generation Inc., Interchurch Uranium Committee Educational Cooperative, Canadian Association of Physicians for the Environment, and Families Against Radiation Exposure (FARE).
