PROS AND CONS OF NUCLEAR POWER IN THE USA
Worldwide, there are 441 nuclear power plants that supply about 16 percent of the world's electricity.
There are currently 104 operating U.S. nuclear power plants that produce over 20 percent of U.S. electricity.

ADVANTAGES a) Nuclear power generation does emit relatively low amounts of carbon dioxide (CO2). The emissions of green house gases and therefore the contribution of nuclear power plants to global warming is therefore relatively little. . USA is currently responsible for a quarter of all carbon dioxide emissions - an average of 40,000 pounds of carbon dioxide is released by each US citizen every year - the

history took place on March 28, 1979 at the Three Mile Island plant in Pennsylvania. A cooling system failed, causing a partial meltdown, but a full meltdown was averted and there were no fatalities. However, despite the positive outcome and despite the passage of more than 30 years, the incident remains fresh in the minds of those who are old enough to remember it. 2. Nuclear Waste Disposal – Again a massive problem as the spent Nuclear Rods of Nuclear Reactors are prohibitively costly and difficult to dispose of. Spent nuclear fuel is initially very highly radioactive and so must be handled with great care and forethought. (10'000 years according to United States Environmental Protection Agency standards).There is no foolproof way to dispose nuclear waste fuel after it is used in the Nuclear Reactors. The area around Nuclear Waste Sites can be dangerous to humans for hundreds of year as complex nuclear elements have half lives running into many years. The United States had accumulated more than 50,000 metric tons of spent nuclear fuel from nuclear reactors. Permanent storage underground in U.S. had been proposed at the Yucca but that project has now been effectively cancelled. There is presently no adequate safe long-term storage for radioactive and chemical waste
