A lot of counters are looking on nuclear power to be the solution for electricity consumption who it expected to double. Even thou many nuclear power plant are reaching the of their life span. However if you look to the whole picture you will see global warming unstable country’s that import oil and gas  and a lot of concern about the future of the world. That is all make the nuclear power the most depend source of power.

I have bad news for anti-nuclear power, 31 reactors are under construction and many more are in the planning stages. Also some countries, such as Turkey and Vietnam, are considering starting nuclear-power programmes, and others, including Argentina and South Africa, plan to expand their existing ones. Both China and India are building several reactors and intend to increase their nuclear-generating capacity several times over in the next 15 years.

In the western world US is expecting a rush of applications to build new reactors in the coming months—the first in almost 30 years. Britain’s Prime Minister, Gordon Brown, recently affirmed his support for a new generation of nuclear power plants. Construction of a new one in Finland, Western Europe’s first for 15 years, began in 2005; work is just starting on another of the same design in France. Other European countries that had frozen or decided to scrap their nuclear programmes are rethinking their plans.

In the world today there are 439 nuclear reactors in 31 countries supply 15% of the world’s electricity. The worldwide producing capacity of nuclear power plants will probably rise from about 370 gigawatts today to 520 gigawatts in 2030. But if there were a price on carbon dioxide, says Mr Birol, “it could grow even faster.” This enthusiasm for nuclear power is responsible. Nuclear reactors emit almost none of the CO2 to the environment; also they are generated by the uranium. which is relatively abundant and is available from many sources, including reassuringly stable places such as Canada and Australia.

However the nuclear reactors are very expansive. It takes billions of dollars to bulled one. Worse, in the past, ill-conceived designs, safety scares and the regulatory delays they gave rise to made nuclear plants even more costly than their hefty price-tags suggest. Vendors of new nuclear plants, such as Areva, General Electric (GE), Hitachi and Westinghouse, argue that things are different now. The latest designs incorporate suggestions from utilities and operators with decades of experience, and should, their creators say, make new plants safer and easier to operate. They believe the simpler new reactors, with their longer lifespans and reduced maintenance costs, will also improve the economics of the industry.
