MIT: Lack of fuel may limit US nuclear power expansion
March 22, 2007CAMBRIDGE, Mass.—Limited supplies of fuel for nuclear power plants may thwart the renewed and growing interest in nuclear energy in the United States and other nations, says an MIT expert on the industry.
Over the past 20 years, safety concerns dampened all aspects of development of nuclear energy: No new reactors were ordered and there was investment neither in new uranium mines nor in building facilities to produce fuel for existing reactors. Instead, the industry lived off commercial and government inventories, which are now nearly gone. worldwide, uranium production meets only about 65 percent of current reactor requirements.
That shortage of uranium and of processing facilities worldwide leaves a gap between the potential increase in demand for nuclear energy and the ability to supply fuel for it, said Dr. Thomas Neff, a research affiliate at MIT's Center for International Studies.
"Just as large numbers of new reactors are being planned, we are only starting to emerge from 20 years of underinvestment in the production capacity for the nuclear fuel to operate them. There has been a nuclear industry myopia; they didn't take a long-term view," Neff said. For example, only a few years ago uranium inventories were being sold at $10 per pound; the current price is $85 per pound.
Neff has been giving a series of talks at industry meetings and investment conferences around the world about the nature of the fuel supply problem and its implications for the so-called "nuclear renaissance," pointing out both the sharply rising cost of nuclear fuel and the lack of capacity to produce it.
Currently, much of the uranium used by the United States is coming from mines in such countries as Australia, Canada, Namibia, and, most recently, Kazakhstan. Small amounts are mined in the western United States, but the United States is largely reliant on overseas supplies. The United States also relies for half its fuel on Russia under a "swords to ploughshares" deal that Neff originated in 1991. This deal is converting about 20,000 Russian nuclear weapons to fuel for U.S. nuclear power plants, but it ends in 2013, leaving a substantial supply gap for the United States.
Further, China, India, and even Russia have plans for massive deployments of nuclear power and are trying to lock up supplies from countries on which the United States has traditionally relied. As a result, the United States could be the "last one to buy, and it could pay the highest prices, if it can get uranium at all," Neff said. "The take-home message is that if we're going to increase use of nuclear power, we need massive new investments in capacity to mine uranium and facilities to process it."
Mined uranium comes in several forms, or isotopes. For starting a nuclear chain reaction in a reactor, the only important isotope is uranium-235, which accounts for JUST 7 out of 1000 atoms in the mined product. To fuel a nuclear reactor, the concentration of uranium-235 has to be increased to 40 to 50 out of 1000 atoms. This is done by separating isotopes in an enrichment plant to achieve the higher concentration.
As Neff points out, reactor operators could increase the amount of fuel made from a given amount of natural uranium by buying more enrichment services to recover more uranium-235 atoms. Current enrichment capacity is enough to recover only about 4 out of 7 uranium-235 atoms. Limited uranium supplies could be stretched if industry could recover 5 or 6 of these atoms, but there is not enough processing capacity worldwide to do so.

In all the world, there are about 200 types of zeolite, a compound of silicon, aluminum and oxygen that gives civilization such things as laundry detergent, kitty litter and gasoline. But thanks to computations by Rice University professor Michael Deem and his colleagues, it appears there are -- or could be -- more types of zeolites than once thought.
Report examines hidden costs of energy production and use
A new report from the National Research Council examines and, when possible, estimates "hidden" costs of energy production and use -- such as the damage air pollution imposes on human health -- that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.
MU Researchers Create Smaller and More Efficient Nuclear Battery
Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
Public attitudes to new technology: Lessons for regulators

Terrestrial Energy: How Nuclear Energy Will Lead the Green Revolution and End America's Energy Odyssey by William Tucker (Author) This is quite possibly the most important book about energy in a generation. For over thirty years Americans have been fed a steady diet of half-truths, misinformation, urban legends and outright fabrications about energy. The small amount of accurate information that does reach us is often obscured by scientific terminology or one-sided political posturing. When faced with a dramatic increase in energy demand, uncertain supplies and the potentially harmful effects of carbon emissions how are we to make informed choices? Veteran journalist William Tucker has relied on years of research and investigation to help us make sense of America s energy predicament without the burdens of political pressures or predetermined outcomes. It seems odd that nuclear energy has... |

Atomic Awakening: A New Look at the History and Future of Nuclear Power by James Mahaffey (Author) Nuclear power is a paradox of danger and salvation—how is it that the renewable energy source our society so desperately needs is the one we are most afraid to use? The American public's introduction to nuclear technology was manifested in destruction and death. With Hiroshima and the Cold War still ringing in our ears, our perception of all things nuclear is seen through the lens of weapons development. Nuclear power is full of mind-bending theories, deep secrets, and the misdirection of public consciousness, some deliberate, some accidental. The result of this fixation on bombs and fallout is that the development of a non-polluting, renewable energy source stands frozen in time. It has been said that if gasoline were first used to make napalm bombs, we would all... |

Nuclear Power Is Not the Answer by Helen Caldicott (Author) The world-renowned antinuclear activist's "expertly argued" (The Guardian) case against nuclear energy. In a world torn apart by wars over oil, politicians have increasingly begun to look for alternative energy sources—and their leading choice is nuclear energy. Among the myths that have been spread over the years about nuclear-powered electricity are that it does not cause global warming or pollution, that it is inexpensive, and that it is safe. Helen Caldicott's look at the actual costs and environmental consequences of nuclear energy belies the incessant barrage of nuclear industry propaganda. Caldicott "reveals truths," Martin Sheen has said, "that confirm we must take positive action now if we are to make a difference." In fact, nuclear power contributes to global... |
