Prospects in the United States for deploying breeders on a large scale were bright when it was beHeved that rich uranium ore would be quickly exhausted as use of nuclear power expanded. The expected demand for uranium was not realized, however. Moreover, the utiliza tion of breeders requires reprocessing (39). In 1979 a ban was placed on reprocessing in the United States. A dampening effect on development of that part of the fuel cycle for breeder reactors resulted. The CRFBP was canceled and France and Japan became leaders in breeder development. 

Spent fuel can be stored or disposed of intact, in a once-through mode of operation, practiced by the U.S. commercial nuclear power industry. Alternatively, spent fuel can be reprocessed, ie, treated to separate the uranium, plutonium, and fission products, for re-use of the fuels (see Nuclear REACTORS, CHEMICAL reprocessing). In the United States reprocessing is carried out only for fuel from naval reactors. In the nuclear programs of some other countries, especially France and Japan, reprocessing is routine. 

Resource pessimists counter that this process cannot proceed forever because the eternal persistence of demand for any given commodity that is destroyed by use must inevitably lead to its depletion. I lowever, the eternal persistence assumption is not necessarily correct. The life of a solar system apparently is long but finite. Energy sources such as nuclear fusion and solar energy in time could replace more limited resources such as oil and natural gas. Already, oil, gas, nuclear power, and coal from better sources have displaced traditional sources of coal in, for example, Britain, Germany, Japan, and France. 

The idea behind energy independence is that if all energy production occurs within a country s borders, then that country s economy will be insulated from any energy supply disruptions. The country would then have less unemployment and less economic decline if and when the world s energy exporters, especially OPEC members, cut their supplies. France, has developed a strong nuclear power industry so that it would not have to import as much oil...

Many dozens of industrialized countries now employ nuclear reactors for power generation, and some countries produce more electrical power by nuclear reaction than by fossil fuel combustion (France is an example). The United States, however, has the largest installed capacity of nuclear-powered boiler plants (in the year 2000 there are more than 120 nuclear reactor power plants in the United States). Nuclear power is also widely used for marine duty in both commercial and naval vessels. 

Aerial views of three nuclear power plants, (a) The Chernobyl nuclear power plant, site of a major nuclear accident in 1986. (b) The Three Mile Island power plant, site of a minor nuclear accident in 1979. (c) A plant in France, which has operated nuclear power plants safely for nearly 30 years. 

A few nations rely heavily on nuclear power despite the possibility of accidents. In France and Japan, fission power from nuclear reactors provides two thirds or more of overall energy needs. A French plant appears in Figure 22-14C. 

An Important difference is In the use of materials which in Prance la only about 2/3 of the United States. Hven greater is the difference of the amount of labor Involved which in France is only about 1/3 of the United States. A still greater ratio exists in the number of engineers and draftsmen required. One reason for that le that a larger fraction of the design la done in the home office rather than in the field. In the United States in 1967 about 3.3 million man hours were required to build a nuclear power plant in 1983 this number had gone up to 30 million man lioura. Field services in the U.S. went from 1.3 to 22 million man hours. 

The presentation by Zaleskl was supplemented by Vendryes. He pointed out that France is particularly favorable for nucleat power. France In 1970 imported 751 of the required energy. France has no oil and only a small amount of coal. Its water power Is quite Insufficient to supply a ratlier large country. Therefore from the very beginning, most of ths French people agreed that nuclear power waa essential. 

Today s situation is virtually the reverse. No new nuclear power plants are under construction in countries that have a competitive electricity market Also, because of World Bank and other lenders reluctance to assist construction of nuclear plant, there are questions how many of the 25 or so reactors, now under construction, will be completed. In countries where public opinion matters, people perceive the risks, but see few benefits, whilst the electricity industry and governments, with a few exceptions, such as France and S. Korea, are too concerned about the vociferous opposition to this power source to do anything, but sit on... 

The use of coal for electricity generation is responsible for about 32% of anthropogenic carbon dioxide emissions in the U S. 11 As shown by France, it is possible to displace virtually all the coal used in electricity generation. Thus, France in 1997 obtained about 78% of its electricity from nuclear power and only about 5% from coal. Further reductions in carbon dioxide emissions could be made by the electrification of other sectors of the energy economy, including buildings, and eventually perhaps much of transportation. 

Indeed, when new countries like the U K. France or China became nuclear powers, countries which were already members of the club were strongly opposed, but now it is quite well accepted that possession of nuclear weapons by those countries did not provoke a catastrophe. Some even consider that the existence of nuclear weapons in different camps was a stabilizing factor during the Cold War and prevented a major conflict during the past half-century. Why, then, the possession by India should not stabilize the relation between India and China, and by Pakistan the relation between Pakistan and India, preventing major conflicts in these zones At least the question may be asked. In the same way, the possession by Israel of nuclear weapons, in the opinion of some, has stabilized the situation in the Middle East. In any case, when a country has decided that it is worth while to make the effort and take the risks of developing nuclear weapons, it seems that after some initial outcry, the world accepts it without major retaliation That shows some kind of hypocrisy in the initial claim of a fundamental evil connected with the proliferation of nuclear weapons. The real issue is probably to avoid the acquisition of nuclear weapons by unstable, not very democratic countries. May be Pakistan is in that category clearly the West would not like Libya or Iran and Iraq to possess such weapons. A real, major issue is full nuclear disarmament, but this is another story. 

It seems increasingly clear that the operating cost (operation and maintenance plus fuel costs) is very competitive with the same cost of its main competitors, coal-and gas fired plants. Therefore, the economic advantage of life extension is obvious, and also the clear trend to operate existing nuclear power plants on base load only. Even in France where there are too many nuclear plants to operate them all on base load, there is a trend to decrease the share of nuclear power in total production in view to operate eventually all... 

Three countries, namely the USA (104 plants), France (59 plants) and Japan, account for approximately 58% of the worldwide generation capacity, followed by Germany and the Russian Federation. These three countries also dominated the historical development of nuclear power expansion (see Fig. 4.1). The three countries with the highest nuclear energy share in their electricity mix today are France, with around 75%, followed by Lithuania, with 70%, and Slovakia, with 55%. While nuclear power contributes some 20% to power generation in the United States, the share in the EU25 is around 36%. 

After the oil crisis in 1973, the need for large enrichment capacities for supply of fuel to the nuclear power plants became obvious and several European countries (Belgium, France, Italy and Spain) decided to build the huge Eurodif gas diffusion plant. This plant is located in France, in the Rhone valley, a few kilometers away from the Pierrelatte plant. Simultaneously, England, West Germany and the Netherlands (the Troika) chose to jointly develop the centrifugation process for uranium enrichment, which does not use membranes. 

A few years later, one had to realize that most of the ambitious plans for building nuclear power plants would be strongly delayed or even abandoned. Only France stuck to its original plans and built a large number of nuclear reactors. The Coredif project did not materialize. In 1982, the membrane production plants of Ceraver, Euroceral and SPEC were shut down and later on dismantled due to the lack of demand for another enrichment plant (the service life of a gaseous diffusion membrane is several decades). For France, this was an abrupt end of the nuclear period for membranes. 

The world use of nuclear power to supply a nation s electricity varies widely by country. France, for example, gets around 75% of its electricity from nuclear power, and several other European countries get over half of their energy from this source. Approximately 20% of the electricity in the United States comes from 103 operating nuclear power plants. Nuclear is second only to coal, 50%, and ahead of natural gas, 15%, hydropower, 8%, and oil, 3%, as a source of electrical energy. Although once hailed by President Eisenhower in the 1950s as a safe, clean, and economical source of power, the US. nuclear industry has fallen on hard times in the last twenty-five years. Nuclear accidents at Three Mile Island, Pennsylvania,... 

During the past few decades, the construction of new nuclear power reactors in the United States has been limited, although this does not hold for France and some other countries, As with any nonrenewable...
