Against Nuclear Power:
I against with the nuclear power plants because it is so dangerous if some explosion

happen by accident and his effects will effect on that environment for a long time to

our generations.


Uranium-235 is the isotope of uranium that is used in nuclear reactors. Uranium-235 can produce 3.7 million times as much energy as the same amount of coal. As an example, 7 trucks, each carrying 6 cases of 2-12 foot high fuel assemblies, can fuel a 1000 Megawatt-electrical (MWe) reactor for 1.5 years. During this period, approximately 2 metric tons of Uranium-235 (of the 100 metric tons of fuel - uranium dioxide) would be consumed. To operate a coal plant of the same output would require 1 train of 89 cars -100 tons of coal each car - EVERY day. Over 350,000 tons of ash would be produced AND over 4 million tons of carbon dioxide, carbon monoxide, nitrogen oxides and sulfur oxides would be released to the environment.


Nuclear power is the problem, not the solution!
Europe must stop wasting taxpayers' money to protect a dangerous and expensive technology. 20 years after the Chernobyl disaster, nuclear power remains the most dangerous mechanism for electricity generation. Nuclear energy is also no solution to climate change. And, globalised terrorism makes nuclear power stations and the uncontrolled proliferation of nuclear material a serious security hazard.
Environmentalists Protest in Sofia against Belene Nuclear Power Plant
9 September 2008, TuesdayProtesters say a missing assessment of the eventual impact on environment, as well as missing license for the technical project of NPP Belene are the main motives behind the rally, staged in front of the Council of Ministers and attended by few.Last week Bulgaria's Prime Minister Sergey Stanishev turned the first sod of the plant announcing the "renaissance of Bulgaria's nuclear energy."Energy Minister Petar Dimitrov said the actual construction works were going to start in May 2009 after the Nuclear Regulation Committee issued the required construction permit.




While the tender is being held, the coalition, which is led by the Electric Engineers Chamber (EMO) will meet in the Kızılay district of Ankara and will march to the Energy and Natural Resources Ministry building, where the tender will take place. One of the coordinators of the group, Mehmet Atay, said they are expecting people who are part of the coalition to demonstrate outside of Ankara, too.

In 1963 the Atomic Energy Commission asked Dr. John Gofman and Dr. Arthur Tamplin to undertake a series of long range studies on potential dangers that might arise from the "peaceful uses of the atom." Assuming that the Atomic Energy Commission seriously wanted to know the truth about the safety of nuclear electricity and its generation, the authors attacked the problem with gusto.
Here's what they learned:
1-Radiation from rapidly expanding Atomic Energy programs is a far, far more serious hazard to human life than anyone had ever conceived it to be.
2; Atomic radiation will result in many times more deaths from cancer and leukemia than previously thought possible. The potential damage to future generations from genetic damage has been even more grossly underestimated.

Nuclear power good for environment

While we devote unprecedented resources to environmental-improvement strategies that have enhanced the quality of life in almost every American city and community, a serious threat to the environment remains ignored. Today's clean air depends upon non-polluting nuclear energy, but precisely because of this dependency, pollution prevention may be approaching an about-face, just as it is achieving enormous benefits.

Nuclear Power: Good Past, Strong Future
Ontarians have been put on notice that around 24,000 megawatts of new electricity supply (or conservation) will be needed over the next two decades. This is equivalent to 80% of the province's current grid capacity.
Since it takes the better part of a decade to plan and build large generating plants, the Ontario Power Authority (www.powerauthority.on.ca) urges the debate to begin soon over how to fill the impending generation gap.
As a backdrop to this debate, the North American public is increasingly aware of the need for effective environmental stewardship.
Fortunately, in Canada we have spent the last 50 years developing a technology that can supply baseload electricity more efficiently than almost anything else on earth, with minimal impact on the biosphere.
CANDU reactors already supply 15% of Canada's electricity, including half the needs of the country's industrial and economic engine, Ontario. Remarkably, they do this while creating virtually no air pollution and a relatively small amount of solid waste, with an operating cost among the lowest of the available generating options.


Costly nuclear power poses unnecessary safety and environmental risks, is heavily dependent on taxpayer and ratepayer subsidies, and generates deadly radioactive waste. Building new nuclear power plants will also not effectively address climate change.
