Uranium Supply Decline Clouds Nuclear Power's Future | LiveScience

Sun, 29 Jun 2008 20:55:48 -0000

Declining uranium supplies suggest nuclear power is not the magic bullet some might have hoped for to replace fossil fuels.

By burning fossil fuels, conventional power plants and vehicles factor in to global warming by emitting carbon dioxide, a greenhouse gas that traps heat from the sun.

Advocates of nuclear power suggest it could help prevent global warming, since nuclear plants generate electricity without releasing carbon dioxide.

But critics of nuclear power have for decades linked it with dangers such as radioactive waste and nuclear weapons. There also remain fears that nuclear plants could undergo catastrophes such as a meltdown, as seen with Chernobyl, or a terrorist attack.

Now it seems that mining uranium, which nuclear power depends on, could be even less environmentally friendly and more costly than critics say, according to a new analysis led by Gavin Mudd, an environmental engineer at Monash University in Australia.

On average, supplies of high-quality uranium ore have been steadily declining worldwide for the past 50 years, and will likely to continue to wane in the mid- to long-term, Mudd said. Any new uranium deposit is likely to be deeper and harder to extract, and getting uranium from lower-quality deposits involves digging up and refining more ore, according to their analysis of government and industry reports.

Stop uranium mining until study is done on impact: coalition

Sun, 29 Jun 2008 16:39:37 -0000

Uranium exploration should be suspended in Ontario until its impact on health, the environment and aboriginal land rights is properly addressed, said a report released yesterday by the Community Coalition Against Mining Uranium.

Highlights and Sticky Notes:

Ontario's Mining Act, passed in 1868 and changed little since, has raised the concern of a number of municipalities that want the province to make changes; including Ottawa, which has asked for an immediate comprehensive public review

Critics are concerned that prospectors can stake a mining claim on private property without notifying landowners, as long as the latter don't possess the mineral rights

The report also urged independent studies into the health of residents in areas where uranium is processed. This includes Port Hope, Blind River and Chalk River. The coalition also called for a halt to new nuclear power plants and suggested money be directed to reducing energy use and increasing sustainable sources of energy.

Port Hope uranium study raises red flags in Sask.

Sun, 29 Jun 2008 16:25:21 -0000

New tests done on residents of Port Hope, Ont., home to the world's oldest uranium processing facility, present a "cautionary tale" for Saskatchewan, an environmental activist says.

Frustrated by the federal government's refusal to examine the health of residents, the Port Hope Community Health Concerns Committee decided to commission its own medical study.

The results, released Tuesday, showed that four of the nine people they paid to have screened for contamination had radioactive chemicals in their bodies.

A month earlier, the company had paid New Brunswick’s provincial government $4 million to buy exclusive uranium prospecting rights for the next year on a 136,000-hectare area between Sussex and Moncton. With the approval of the provincial government secured, the mining giant turned its attention to Moncton.

Environmental monitoring revealed a sharp increase of uranium loads in lake sediments near the operating Rabbit Lake mine in Saskatchewan. While natural uranium levels in the lake sediment are below 3 µg/g (3 micro grams per gram), levels in Hidden Bay had reached approx. 25 µg/g in 2000, and have more than doubled each year since, to approx. 250 µg/g in 2003. It is reassuring, though, that... "This has been recognized by the company and they are looking into ways of reducing uranium in the effluent."...

Highlights and Sticky Notes:

little is known about chronic exposures, for example, if there is a direct chemical genotoxicity of uranium

These data suggest that uranium may be directly genotoxic and may, like chromium, react with DNA by more than one pathway.

Durakovic: Internal Contamination with Uranium

Fri, 27 Jun 2008 15:53:44 -0000

Highlights and Sticky Notes:

The chemical toxicity of uranium has been recognized for more than two centuries

Animal experiments and human studies are conclusive about metabolic adverse affects and nephro- toxicity of uranium compounds

reproductive and developmental toxicity

mutagenic and carcinogenic consequences of uranium internal contamination

The medical and environmental consequences of contamination with uranium compounds present both a moral and legal requirement to control uranium exposure to levels below those causing pathological alterations or death, either by its immediate or long-term action
