Although nuclear plant security is designed to protect against significant and extended forms of terrorism, the NRC believes as many as one-fourth of the 104 U.S. nuclear plants may need upgrades to withstand earthquakes and other natural disasters, according to an Associated Press investigation. About 20 percent of the world's 442 nuclear plants are built in earthquake zones, according to data compiled by the International Atomic Energy Agency.
The NRC has determined that the leading U.S. plants in the Eastern Coast in danger of being compromised by an earthquake are in the extended metropolitan areas of Boston, New York City, Philadelphia, Pittsburgh, and Chattanooga. Tenn. The highest risk, however, may be California's San Onofre and Diablo Canyon plants, both built near major fault lines. Diablo Canyon, near San Luis Obispo, was even built by workers who misinterpreted the blueprints.
Every nuclear spill affects not just those in the immediate evacuation zone but people throughout the world, as prevailing winds can carry air-borne radiation thousands of miles from the source, and the world's water systems can put radioactive materials into the drinking supply and agriculture systems of most nations. At every nuclear disaster, the governments eventually declare the immediate area safe. But, animals take far longer than humans to return to the area. If they could figure out that radioactivity released into the water, air, and ground are health hazards, certainly humans could also figure it out.
Following the disaster at Daiichi, Germany announced it was closing its 17 nuclear power plants and would expand development of solar, wind, and geothermal energy sources. About the same time, Siemens abandoned financing and building nuclear power plants, leaving only American-based Westinghouse and General Electric, which own or have constructed about four-fifths of the world's nuclear plants, and the French-based Areva.
The life of the first nuclear plants was about 30--40 years; the newer plants have a 40--60 year life. After that time, they become so radioactive that the risk of radiation poison outweighs the benefits of continuing the operation. So, the operators seal the plant and abandon it, carefully explaining to the public the myriad safety procedures in place and the federal regulations. The cooling and decommissioning takes 50--100 years until the plant is safe enough for individuals to walk through it without protection. More critical, there still is no safe technology of how to handle spent control rods.
The United States has no plans to abandon nuclear energy. The Obama administration has proposed financial assistance to build the first nuclear plant in three decades, and a $36 billion loan guarantee for the nuclear industry. However, the Congressional Budget Office believes there can be as much as 50 percent default. Each plant already receives $1--1.3 billion in tax rebates and subsidies. However, in the past three years, plans to build nuclear generators have been abandoned in nine states, mostly because of what the major financiers believe to be a less than desired return on investment and higher than expected construction and maintenance costs.
A Department of Energy analysis revealed the budget for 75 of the first plants was about $45 billion, but cost overruns ran that to $145 billion. The last nuclear power plant completed was the Watts Bar plant in eastern Tennessee. Construction began in 1973 and was completed in 1996. Part of the federal Tennessee Valley Authority, the Watts Bar plant cost about $8 billion to produce 1,170 mw of energy from its only reactor. Work on a second reactor was suspended in 1988 because of a lack of need for additional electricity. However, construction was resumed in 2007, with completion expected in 2013. Cost to complete the reactor, which was about 80 percent complete when work was suspended, is estimated to cost an additional $2.5 billion.
The cost to build new power plants is well over $10 billion each, with a proposed cost of about $14 billion to expand the Vogtle plant near Augusta, Ga. The first two units had cost about $9 billion.
Added to the cost of every plant is decommissioning costs, averaging about $300 million to over $1 billion, depending upon the amount of energy the plant is designed to produce. The nuclear industry proudly points to studies that show the cost to produce energy from nuclear reactors is still less expensive than the costs from coal, gas, and oil. The industry also rightly points out that nukes produce about one-fifth all energy, with no emissions, such as those from the fossil fuels.
For more than six decades, this nation essentially sold its soul for what it thought was cheap energy that may not be so cheap, and clean energy that is not so clean.
It is necessary to ask the critical question. Even if there were no human, design, and manufacturing errors; even if there could be assurance there would be no accidental leaks and spills of radioactivity; even if there became a way to safely and efficiently dispose of long-term radioactive waste; even if all of this was possible, can the nation, struggling in a recession while giving subsidies to the nuclear industry, afford to build more nuclear generating plants at the expense of solar, wind, and geothermal energy?
