A Nuclear Energy Renaissance Wouldn't Solve Our Problems, But It Would Rip Us Off

By Christian Parenti, The Nation. Posted May 6, 2008.


Talk of a nuclear renaissance is a dangerous distraction from the real changes we need to make to wean ourselves off oil.

If you listen to the rhetoric, nuclear power is back. Smashing atoms will replace burning carbon-based coal, gas and oil. In the face of a disaster movie-like future of runaway climate change -- bringing drought, floods, famine and social breakdown -- carbon-free nukes are cast as the deus ex machina to save us at the last minute.

Even a few greens support nuclear power -- most famously James Lovelock, father of the Gaia theory. In the popular press, discussion of nuclear energy is dominated by its boosters, thanks in part to sophisticated industry PR.

In an effort to jump-start a "nuclear renaissance," the Bush Administration has pushed one package of subsidies after another. For the past two years a program of federal loan guarantees has sat waiting for utilities to build nukes. Last year's appropriations bill set the total amount on offer at $18.5 billion. And now the Lieberman-Warner climate change bill is gaining momentum and will likely accrue amendments that will offer yet more money.

The Nuclear Regulatory Commission (NRC) expects up to thirty applications to be filed to build atomic plants; five or six of those proposals are moving through the complicated multi-stage process. But no new atomic power stations have been fully licensed or have broken ground. And two newly proposed projects have just been shelved.

The fact is, nuclear power has not recovered from the crisis that hit it three decades ago with the reactor fire at Browns Ferry, Alabama, in 1975 and the meltdown at Three Mile Island in 1979. Then came what seemed to be the coup de grâce: Chernobyl in 1986. The last nuclear power plant ordered by a U.S. utility, the TVA's Watts Bar 1, began construction in 1973 and took twenty-three years to complete. Nuclear power has been in steady decline worldwide since 1984, with almost as many plants canceled as completed since then.

All of which raises the question: why is the much-storied "nuclear renaissance" so slow to get rolling? Who is holding up the show? In a nutshell, blame Warren Buffett and the banks -- they won't put up the cash.

"Wall Street doesn't like nuclear power," says Arjun Makhijani of the Institute for Energy and Environmental Research. The fundamental fact is that nuclear power is too expensive and risky to attract the necessary commercial investors. Even with vast government subsidies, it is difficult or almost impossible to get proper financing and insurance. The massive federal subsidies on offer will cover up to 80 percent of construction costs of several nuclear power plants in addition to generous production tax credits, as well as risk insurance. But consider this: the average two-reactor nuclear power plant is estimated to cost $10 billion to $18 billion to build. That's before cost overruns, and no U.S. nuclear power plant has ever been delivered on time or on budget.

As Dieter Helm, an Oxford professor and leading economic expert on energy markets, has found, there never has been and never will be a nuclear power program totally dependent on the market.

Sixty years ago, the technology was swathed in manic space-age optimism -- its electricity was going to be "too cheap to meter." While that wasn't true, nuclear power did serve a key role in the cold war: spent nuclear fuel rods are refined for weapons-grade plutonium and enriched uranium. That fact aside, rarely has so much money, scientific know-how and raw state power been marshaled to achieve so little. By some estimates, an investment of several hundred billion dollars has led to a U.S. nuke industry of 104 operating plants -- about a quarter of the global total -- that produces a mere 19 percent of our electricity.

In fact, the sputtering decline of nuclear power has been one of the greatest industrial failures of modern times. In 1985 Forbes called the nuke industry "the largest managerial disaster in history."

Atomic optimism run amok caused the largest municipal bond default in U.S. history. In 1983 Washington Public Power Supply System abandoned three nuke plants in midconstruction. The projects were plagued by massive cost overruns -- one infamous section of piping was reinstalled seventeen times, safety inspections were blatantly ignored, incompetent contractors were allowed to continue work and on and on. When the project finally died, unfinished costs had ballooned to $24 billion, and the utility walked away from $2.25 billion worth of bonds.

That project, like many others, drowned in the financial riptides of rising interest rates that were the central feature of the "Volcker recession" of the early '80s. (That was when Federal Reserve chairman Paul Volcker smashed inflation by jacking the Fed's interest rate from 8 percent in 1979 to more than 16 percent in 1982.) But nukes were also killed by the corruption and incompetence that so often plague large state projects, like Boston's Big Dig, the New Orleans levees, space-based weapons systems and Iraq's reconstruction.

That is a lie. The problem is protesters.
The low carbon source of the electricity has to be nuclear
to replace the base load capacity of coal.

Nuclear power is 30% cheaper than the coal power we have been
duped into using. We have 5000 years worth of nuclear fuel if
we recycle it rather than waste it as we do now. Nuclear is also
the safest, cleanest and cheapest form of energy available.

Chernobyl again
Posted by: AsteroidMiner on May 6, 2008 3:29 AM   
Current rating: 2    [1 = poor; 5 = excellent]
A friend of mine from Oak Ridge National Laboratory wrote to
me: "The reactor that had the accident at Chernobyl was very out-
of-date (1st generation) design that has to be precisely controlled
to prevent cooling water from boiling. Water carries away heat
and moderates far better than bubbles, and as bubbles form in
water, the reactor goes increasingly unstable. What caused
Chernobyl to blow its top was residual water in the core suddenly
going to high pressure steam and erupting into a steam explosion.
Since the building top was simply resting by its weight on the
walls, not a containment vessel at all, the steam explosion burped
the top off its position allowing outside air in, subsequently
igniting a carbon fire." The United States and other Western
countries DO NOT now build and do not now posses or operate
ANY reactors of such primitive design. Nor do we allow
containment buildings to have easily removable tops.
Containment buildings in the Western hemisphere are required to
be pressure vessels.
The Chernobyl accident released only 200 tons of
radioactive material, as much as a coal-fired power plant would
release in 7 years and 5 months. The Chernobyl accident had a
shorter "stack" than coal-fired power plants. The radioactive
material was released in a short time at ground level. That is why
the Chernobyl accident had impact. The Three Mile Island
incident did NOT release a noticeable amount of radiation into its
neighborhood because it had a good containment building and
because it was a more modern design.
The reason is that the Soviet Union didn't spend money on R&D
for nuclear safety. The US did. Over 60 years, American
reactors have become so safe it is ridiculous. We have way
overspent on nuclear reactor safety, driving up the cost of
electricity. Meanwhile, back at the ranch, coal fired electric
power plants kill 24,000 people per year in the US according to
Discover magazine. Reactors built in the US in 2008 are nothing
like the very first reactor ever, built in the US in 1944. Soviet
built reactors were just copies of the 1944 reactor.
The book: "Environmentalists for Nuclear Energy", by B. Comby
has more truthful information on this if you are interested. Don't
believe the urban legends that were started by coal companies.
Order the book from: http://www.comby.org/livres/livresen.htm
See: http://www.ecolo.org for more information on the book.
Most books on the subject in most libraries may be there because
of coal industry pressure.

I have no connection with the nuclear power industry. Nobody is
paying me to post this. I have never worked for the nuclear
power industry.

All Western nuclear power plants have Containment Buildings
which protect the world outside from anything that can possibly
happen in the core. Western containment buildings are why
Chernobyl cannot happen in the US. Containment buildings are
pressure vessels, unlike the building the Chernobyl reactor was in.
The walls, ceiling and floor are a minimum of 1 meter [about 39
inches] thick and HEAVILY reinforced with steel. There is so
much steel reinforcing rod that when you look at one under
construction, you wonder where there will be any room for
concrete. There is no explosion that could ever happen inside the
core or the containment building that would have any chance at all
of making a hole in the containment building. The containment
building is many times stronger than required to contain any
explosion that could happen there.

since coal industry inspired protests and endless pointless
delaying tactics have needlessly run up the time and cost. Of
course the coal industry has a need to prevent nuclear power.
The coal industry would loose any fair competition with nuclear
power and the coal industry is a $100 Billion business in the US
alone. $100 Billion/year is plenty of reason for yet another anti-
nuclear article.

if the coal industry has anything to say about it. Meanwhile, the
burning of coal is putting 100 times as much radiation into your
environment. Besides carbon, coal also contains: URANIUM,
ARSENIC, LEAD, MERCURY, Antimony, Cobalt, Nickel,
Copper, Selenium, Barium, Fluorine, Silver, Beryllium, Iron,
Sulfur, Boron, Titanium, Cadmium, Magnesium, Thorium,
Calcium, Manganese, Vanadium, Chlorine, Aluminum,
Chromium, Molybdenum and Zinc. There is so much of these
elements in coal that cinders and coal smoke are actually valuable
ores. We should be able to get all the uranium and thorium we
need to fuel nuclear power plants for centuries by using cinders
and smoke as ore. Remember that, to get a given amount of
energy, you need on the order of 100 MILLION TIMES as much
coal as uranium. That means the coal mine has to be 100 million
times larger than the uranium mine, not counting the recycling of
nuclear fuel. We can keep our mountains and forests and our
health by switching from coal to nuclear power.

Chinese industrial grade coal is sometimes stolen by
peasants for cooking. The result is that the whole family
dies of arsenic poisoning because Chinese industrial grade
coal contains large amounts of arsenic.

I have zero financial interest in nuclear power, and I never have
had a financial interest in nuclear power. My sole motivation in
writing this is to avoid extinction by global warming.

Aside from any other consideration, Nukes don't work without massive public subsidy. No insurer will underwrite the full liability of one of these monsters- much less all of them. The funny thing is that the same morons that advocate free markets seek to use the government to cover the huge liability problem.
If the 9-11 attackers had hit the plant just upriver from the city the ENTIRE NYC area would be a dead zone. Imagine what kind of liability those numbers look like.

spent nuclear fuel rods are refined for weapons-grade plutonium and enriched uranium
Posted by: AsteroidMiner on May 6, 2008 4:30 AM   
Current rating: 3    [1 = poor; 5 = excellent]
Not in this country. We WASTE all that expensive reactor fuel.
The government has its own fast breeders to make plutonium for
bombs. Plutonium is good reactor fuel.
We don't recycle nuclear fuel because spent fuel is valuable and people steal it.
The place it went that it wasn't supposed to go to is Israel. This happened in a
small town near Pittsburgh, PA circa 1970. A company called Numec was in the
business of reprocessing nuclear fuel. I almost took a job there, designing a
nuclear battery for a heart pacemaker. [A nuclear battery would have the
advantage of lasting many times as long as any other battery, eliminating many
surgeries to replace batteries.] Numec did NOT have a reactor. Numec "lost"
half a ton of enriched uranium. It wound up in Israel. The Israelis have fueled
both their nuclear power plants and their nuclear weapons by stealing nuclear
"waste." It could work for any other country, such as Iran or the United States.
It is only when you don't have access to nuclear "waste" that you have to do the
difficult process of enriching uranium.
Numec is no longer in business. Terrorists can't compete with Mossad and
Israeli dual citizens who are CEOs of companies like Numec. Israeli nuclear
weapons are exact duplicates of American nuclear weapons. All persons who
were "born of Jewish mothers" are citizens of Israel regardless of any other fact.
Since the US can't and shouldn't discriminate, the reprocessing of nuclear fuel in
the US stopped. That was the only politically possible solution at that time,
given that private corporations did the reprocessing. My solution would be to
reprocess the fuel at a Government Owned Government Operated [GOGO]
facility. At a GOGO plant, bureaucracy and the multiplicity of ethnicity and
religion would disable the transportation of uranium to Israel or to any
unauthorized place. Nothing heavier than a secret would get out.

In France, nuclear power produces 80% of France's electricity at a
30% lower price. Nuclear power consistently undersells coal
fired power in the US despite everything the coal industry has
done. In France, the industry pays royalties to the government.
There are negative subsidies. France sells electricity to Germany
and other countries that try to get along without nuclear power.

WRONG. Oxidation has nothing to do with nuclear power but
uranium does burn well. Nuclear fuel is ALREADY uranium
oxide. The nuclear fission process is not burning. Nuclear
fission produces on the order of 100 Million times as much energy
as burning the same number of carbon atoms.

Background radiation
From Wikipedia, the free encyclopedia
http://en.wikipedia.org/wiki/Background_radiation

Background radiation is the ionizing radiation from several natural radiation
sources: sources in the Earth and from those sources that are incorporated in our
food and water, which are incorporated in our body, and in building materials and
other products that incorporate those radioactive sources; radiation sources from
space (in the form of cosmic rays); and sources in the atmosphere which primarily
come from both the radon gas that is released from the earth's surface and
subsequently decays to radioactive atoms that become attached to airborne dust
and particulates, and the production of radioactive atoms from the bombardment
of atoms in the upper atmosphere by high-energy cosmic rays. Since 1945 it also
comes from low levels of global radioactive contamination due to nuclear testing.

Natural background radiation

Natural background radiation comes from three primary sources: cosmic radiation,
terrestrial sources, and radon. The worldwide average background dose for a
human being is about 2.4 mSv per year. This exposure is mostly from cosmic
radiation and natural isotopes in the Earth.

Cosmic radiation

The Earth, and all living things on it, are constantly bombarded by radiation from
outside our solar system of positively charged ions from protons to iron nuclei.
This radiation interacts in the atmosphere to create secondary radiation that rains
down, including X-rays, muons, protons, alpha particles, pions, electrons, and
neutrons. The dose from cosmic radiation is largely from muons, neutrons, and
electrons.

The dose rate from cosmic radiation varies in different parts of the world based
largely on the geomagnetic field and altitude.

Terrestrial sources

Radioactive material is found throughout nature. It occurs naturally in the soil,
rocks, water, air, and vegetation. The major radionuclides of concern for terrestrial
radiation are potassium, uranium and thorium. Each of these sources has been
decreasing in activity since the birth of the Earth so that our present dose from
potassium-40 is about 1⁄2 what it would have been at the dawn of life on Earth.
Some of the elements that make up the human body have radioactive isotopes,
such as potassium-40, so there is also a very small amount of internal radiation.

Radon

Radon gas seeps out of uranium-containing soils found across most of the world
and may concentrate in well-sealed homes. It is often the single largest contributor
to an individual's background radiation dose and is certainly the most variable in
the United States. Many areas of the world, including Cornwall and Aberdeenshire
in the United Kingdom have high enough natural radiation levels that nuclear
licensed sites cannot be built there—the sites would already exceed legal radiation
limits before they opened, and the natural topsoil and rock would all have to be
disposed of as low-level nuclear waste.

............shortened.............

The exposure for an average person is about 360 millirems/year, 80 percent of
which comes from natural sources of radiation. The remaining 20 percent results
from exposure to artificial radiation sources, such as medical X-rays and a small
fraction from nuclear weapons tests.

wind
Posted by: AsteroidMiner on May 6, 2008 5:55 AM   
Current rating: 3    [1 = poor; 5 = excellent]
Wind energy requires that Direct Current [DC] be transmitted
over enormous areas [more than one continent] to provide
continuous power because wind varies from minute to minute.
Direct current is required because the voltage and frequency of
AC would change minute by minute with wind speed. Long
distance DC transmission requires superconducting cable. DC
just doesn't go far otherwise.
Reference:
http://www.terrawatts.com: Liquid nitrogen is still required.
http://www.alternet.org/environment/69888

Following the http://www.terrawatts.com lead, you arrive at the
statement that the "high temperature" superconductor will be
cooled by liquid nitrogen. See:
http://www.azom.com/details.asp?
ArticleID=942#_When_will_HTS
The need for liquid nitrogen or liquid helium is the Achilles heal
of this scheme. It isn't really a "room" temperature
superconductor. Any accidental warming brings the grid to a
halt. Energy is required to make liquid nitrogen. Dry nitrogen
must be cooled to 77 degrees Kelvin to make it a liquid. [Zero
degrees Kelvin is absolute zero, -273.15 degrees Centigrade.]
Liquid helium is at 4 degrees Kelvin or colder. Superconduction
usually means a requirement for liquid helium. Liquid Helium is
very expensive. The cable has to be thermally insulated and
cooled its entire length. The cable also must be physically
separated into "out" and "return" wires, and the force between the
2 wires will be large. As stated in the article I gave you the URL
of, it won't be cheap.

Any warming above the superconducting temperature or too much
magnetic field will cause the cable to quit superconducting at that
point. The cable will instantly melt, creating an electric arc. All
of the energy that was flowing through that spot will instead be
dumped there, creating an explosion. The power grid will be
disabled for some time since repairing a superconducting cable is
not as easy as splicing a wire. Is this the kind of electric service
you really want? We really don't have the technology yet.

What about storing wind energy as compressed air? Check the
efficiency, the availability of leak proof caverns, etc. Storing
wind energy as compressed air is a pie in the sky. What about
storing wind energy in batteries? We can't make that many
batteries. Another pie in the sky.

Wind energy wastes energy because the wind varies so much that
a "spinning reserve" is required in most locations. If you are
running the steam powered generator at the spinning reserve rate,
you may as well use the steam as your energy source and forget
about the wind. Wind turbines are decorations, not sources of
energy for the grid until we have room temperature
superconductors. There are special locations and circumstances
where wind energy is useful, but wind cannot replace coal and
nuclear any time soon. Nuclear power is the only kind that can
actually take coal fired power plants off line. If allowed to
compete, nuclear power would already have replaced coal fired
power because nuclear is 30% cheaper and 24000 American lives
per year safer.

Cost-Solar-Power/300005422

The Cost of Solar Power   From Dan M.'s Blog  
by Dan M.
"One source that seems good is solarbuzz.com(1)(2). From the
name, it sounds like a pro solar energy source, but the data seem
to be realistic.
From the first referenced page at this site, we see that residential
costs have dropped 6% to 37.59 cents/kwH, while
commercial/wholesale costs have dropped 0.6% between July
2000 and November 2007 to 21.37 cents/kwH. "
"For comparison purposes, the wholesale price of electricity was
0.06 cents/kwH. "

Dividing the solar cost by the wholesale grid price, we see that
solar power costs 356.2 to 626.5 times as much as electricity from
the wholesale grid. That is during the daytime. At night, the
cost of solar power is much higher because you have to add the
cost of energy storage, the cost of converting the energy to store
it, the cost of converting the energy back, and all of the
inefficiencies. You would be lucky to get 5% efficiency overall
for stored energy, so multiply by at least 20 purely because of
inefficiency. Double or multiply by some larger number the
capital cost to cover the cost of storage. Solar power is
unaffordable at night.
