Nuclear Waste Solution
If technology continues to advance for the next 100 years at
the pace we have witnessed in the past, then future technology will solve
many
of
the problems we face today. For this reason, it is safe to assume that
engineers in the 22nd century and beyond will not consider nuclear waste
— or radioactivity
of any kind — too great of a problem to solve (and it is likely that
technological advancements will solve the problem before the end of the 21st
century).
Take a couple of minutes and try to imagine the tools and technology
that will be available to nuclear engineers and scientists 50 years
from now.
One obvious possibility is advanced robotics that will surpass anything
we have imagined in cost, capability and widespread use. The handling
of radioactive material through future robotics could eliminate all risk
of radiation exposure to humans—not only during normal maintenance
and inspections like that which is performed today, but also work that
cannot be done today because of risk of radiation exposure, such as performing
detailed work with the dexterity that now requires direct human contact—hands
and fingers. Future technology will enable an operator to use remote
robotics with the ease and dexterity equivalent to direct
human
touch. And, in the not so distant future, such technology will be available
for less than hundreds of dollars, not tens of thousands of dollars.
Future advances in Nuclear Chemistry and Metallurgy will likely produce
technology that will enable inexpensive reprocessing of spent nuclear
fuel as well as inexpensive and reliable methods of reducing or eliminating
long-term radioactivity.
Think of it this way, what if our forefathers (and mothers) worried over
the thought of “dumping” on future generations, their libraries
of printed books and papers. What if they believed they had the responsibility
of perfecting digital memory storage?
The computer was invented in 1837
by Charles
Babbage. The machine was called an Analytical Engine, “it
was a mechanical digital computer which, viewed with the benefit
of a
century and a half's hindsight, anticipated virtually every aspect
of present-day computers.”
What
if the politicians of Babbage's day had been persuaded to spend the
enormous capital required to achieve the goal of digitizing all printed
literature that existed in 19th century libraries? Imagine attempting
such a goal restrained by the limited and, from our
21st century perspective, primitive technology of the 19th century.
Today an eight year old child has access to the tools and knowledge needed
to digitally record more information in one hour than 19th century
scientists could have recorded
in one hundred years.
But, what if the 19th century leaders and engineers were faced with a choice:
either digitize all written literature now, or ban the publication
of all books until the digital technology is available?
21st century leaders and nuclear engineers are faced with a similar choice
today: either permanently bury all nuclear “waste” today,
guaranteeing that no radioactive material will escape from the burial
place, forever, or ban nuclear energy until technology is available
to accomplish the goal.
Why the rush to permanently
bury spent (waste) nuclear fuel? Yes, we need to get it out
of the cities and away from the nuclear power plants so the nuclear
plants can do
their job without concern for spent fuel storage, but why the rush
to have the
FINAL burial place?
Human civilization will have no reason to fear nuclear waste left over from
the 20th and 21st century. Simply store it above ground today, safely, and
wait for future technology. The technology is coming faster than you realize.
And the problem never was as big as you have been led to believe.
Can we trust future generations of scientists and engineers
to complete what our generation has begun? Yes we can! And, future
generations will applaud our foresight and be grateful that we chose
to store our
spent nuclear material in a safe but accessible location.
Scientists tell us that all of the spent nuclear fuel existing in the
USA today could be stored safely in a building the size of a Wal-mart
Superstore, with modifications of course.
“As
of April 2008, the United States [has] accumulated about 56,000 metric
tons of spent nuclear fuel from nuclear reactors. In addition, there
will be about 22,000 canisters of solid defense-related radioactive waste
for future disposal in a repository.
“To put this in perspective, if we were to take all the nuclear waste produced
to date in the United States and stack it side-by-side, end-to-end,
it would cover an area about the size of a football field to a depth of
about ten feet.”
How Much Nuclear Waste is in the United States?
Electricity was generated for the first time by a nuclear reactor on
December 20, 1951 at the EBR-I experimental station near Arco, Idaho.
Today the USA has 104 nuclear reactors generating about 20% of total
U.S. electricity. Over the past 57+ years the nuclear “waste” from these
reactors has been carefully collected and safely stored onsite at the
nuclear power plants. But the onsite storage cooling pools are filling
up, and
it is past time to move the spent fuel to a federal storage site.
56,000
tons of spent fuel needs a new home. But some people are afraid of
the radioactivity. Some people are also afraid of the dark and afraid
of
flying, but that should not dictate federal policy about how to handle
and store spent nuclear fuel.
The total “waste” from a lifetime of energy consumed by one
person—if all of their energy was produced by nuclear power—is
about the size of a soft-ball.
|
The total volume
of nuclear waste material, including all military related nuclear waste,
accumulated over 57+ years is less than .01% (one hundredth of one percent)
of the total volume of coal burned every year in the USA—every
year!
56,000 tons of nuclear waste accumulated over a half century. How much
is that, really? The aircraft carrier in this picture weighs between
70,000 and 100,000 tons. They are big; but most of the size is due to
empty space inside the ship—space
required for crew, storage and work areas. For the sake of illustration,
how big do you think the ship would be if it was flattened to a solid
form, eliminating the empty space inside, and then folded until
the solid
form
was twenty
feet thick? The total volume
of the
crushed ship could be placed in a space requiring
less than
an
acre of
land. (The deck of an aircraft carrier covers the equivalent of about
five acres.)
So, why do we worry about nuclear waste disposal? What is the problem?
Store it safely above ground for another hundred years. Any well trained,
experienced civil engineer can design and construct above ground containers
what will not “leak” during the next one hundred years. In
the meantime continue public funding for future nuclear energy
Research and development, and make sure that the above ground repository
is accessible to the research scientists.
It might be a good idea to store all of the country's spent nuclear
fuel above ground at the
Idaho
National Laboratory, where many of our nation's nuclear scientists
are already working to solve these problems and create a sustainable
nuclear
energy
future. The Idaho
National Laboratory (INL) is an 890-square-mile complex located in the
Idaho desert between the town of Arco and the city of Idaho Falls. At
640 acres per square mile, the INL has more than
a half million acres, mostly barren land, where the USA could store a
thousand years of accumulated spent nuclear fuel if needed. The storage
facility should be called a Strategic Uranium Reserve, rather
than refering
to it as a nuclear waste dump.
Scientists tell us that spent uranium fuel removed
from today's light-water reactors, after producing the intense heat required
for more than a year of electricity generation, is still a good source
of future energy. The potential energy remaining in the spent fuel is
60 times greater than the energy already produced by the light-water
reactor. Light-water
reactors consume less than 2% of the potential energy within the
uranium fuel. The light-water reactor technology is incapable of using
the remaining energy within the spent uranium, which is why it is called “spent
fuel.” But the spent fuel is not “waste” — if
the spent fuel is kept for another 50 years, then the new advanced nuclear
reactors (fast
reactors), which scientists are developing
today,
will
be
capable
of
consuming
the energy
remaining
in
the spent
fuel — if the spent fuel is stored in a safe but accessible
place for the next 50 years or so, then when future advanced reactors
replace the older light-water reactors, they
would have access to the fuel.
“Through the release of atomic energy, our generation has brought into
the world the most revolutionary force since prehistoric man's discovery of
fire.” —Albert Einstein
“The great advantage of nuclear power is
its ability to wrest enormous energy from a small volume of fuel. Nuclear
fission, transforming matter directly to energy is several million times
as energetic as chemical burning, which merely breaks chemical bonds.
One ton of nuclear fuel produces energy equivalent to 2 to 3 million tons
of fossil fuel… Running a 1000 mega-watt (a continuous one million
kilowatt) power plant for a year requires 2000 train cars of coal or 10
supertankers of oil but only 12 cubic meters of natural uranium…
The spent nuclear fuel and other radioactive waste requiring disposal
after one year would be about 20 cubic meters in all when compacted (roughly,
the volume of two automobiles)… The high-level waste is intensely
radioactive, of course… But thanks to its small volume and the fact
that it is not released into the environment, this high-level waste can
be meticulously sequestered behind multiple barriers. Waste from coal,
dispersed across the landscape in smoke or buried near the surface, remains
toxic forever. Radioactive nuclear waste decays steadily, losing 99% of
its toxicity after 600 years – well within the range of human experience…
Nuclear waste disposal is a political problem in the United States because
of widespread fear disproportionate to the reality of risk. But it is
not an engineering problem.”

Need For Nuclear Power, by Richard Rhodes and Denis Beller

By all practical definitions, nuclear fission is a sustainable source of energy.
Enough uranium exists in the earth's crust and oceans to last thousands of
years. Future advanced fast reactors will produce 60 to 100 times more energy
out of the uranium fuel, extending the reserves to tens of thousands of years.
"The fast
reactor with a pyroprocessing-based
fuel cycle can provide a vast improvement in energy efficiency. By recycling
spent fuel, such a fast reactor system can deliver 100 times more energy
from available uranium resources than today's reactors without harmful
greenhouse gas emissions thereby assuring a sustainable long-term energy
source." Advanced Fast Reactor (AFR)
If the United States would plan for a nuclear energy future based on
fast reactors using The Advanced Nuclear Fuel Cycle, then the
spent fuel from existing light-water reactors would not be considered
nuclear waste dumped on future generations. Today's spent nuclear fuel
would be considered a gift of energy to future generations and stored
in a safe place as a “strategic uranium reserve” to become
fuel for future fast reactors. After the future advanced reactors consume
the remaining energy in the fuel, there will still be a need for permanent
disposal of the end product—the final nuclear waste—but the
total volume would be much less than it is in its current form, and it
would remain radioactive for less time—hundreds of years instead
of thousands of years.
Opposition to the Yucca Mountain repository is based on fear of radiation
leaks 10,000 years from now. Such fears assume that earth, in the future,
will be populated
by primitive humans similar to the Neanderthals who lived on earth about
500,000 years ago. Why else would the future inhabitants of earth unexpectedly
stumble upon an ancient nuclear burial ground? Such worrisome nonsense
is due to a lack of faith in human progress.
Has anyone stopped to
realize that many toxic metals and chemicals dumped in public landfills,
such as lead and cadmium from batteries, do not have half-lives? lead
and cadmium, along with a host of other chemicals that end up in public
landfills are carcinogenic and mutagenic, but unlike radioactive material,
they will remain toxic
forever. So, why has the media fixated on Yucca
Mountain, ignoring public landfill leakage? The ground water in Nevada
is at far greater risk from public landfill leakage over the next 10,000
years than it ever will be from the Yucca Mountain nuclear repository.
But for some reason, the media and media driven politicians have allowed
anti-nuclear propaganda to convince them that dying from cancer caused
by landfill toxins is not as bad as dying from cancer caused by radioactive
toxins.
“Stated succinctly, the potential hazard of
nuclear waste is no greater than that of many other commonly accepted
industrial activities in today's world and the concern related to its
longevity (half-life) is absurd when compared to current levels of concern
related to use of stable toxic elements (e.g., lead, cadmium, mercury)
which last forever.
“The major concerns related to nuclear waste
management can be expressed in terms of hazard and longevity. These concerns
may be paraphrased as follows:
- First, waste is extremely
toxic. The radioactive waste from a single nuclear reactor is enough
to poison the entire population of the world several times over. It
could cause malignancy and other diseases to exposed populations and
genetic defects to their descendants.
- Second, because of the extremely
long half-life of plutonium and some of the other components, its
toxicity will persist for thousands, and perhaps millions of years.
“Both of these statements are true. However,
when viewed in a different perspective, they lose their specter of severity.
For example, a valid analogy to the first statement would be the observation
that considering such items as cleaning compounds, pesticides, and other
chemicals, there is enough toxic material in the average supermarket or
hardware store to poison everyone in the community, if not the entire
state. The problem has been one of confusing toxicity with hazard. The
mere existence of a toxic substance does not constitute a hazard, unless
that substance is readily available for dissemination and assimilation
in the human body.
“Consider, for example, that the lead used
in the manufacture of automobile batteries in this country each year is
also sufficient, if properly distributed, to poison the entire world population
several times over. Although long half-lived radionuclides in radioactive
waste may persist for centuries or millennia, lead, being a stable element,
will exist forever. In addition, lead is also a carcinogen and a mutagen.
Nevertheless, lead in automobile batteries is not generally considered
to be a serious environmental threat, simply because of its low availability
for human assimilation. The annual production of lead in this country,
if administered by ingestion, would be sufficient to kill far more people
than the annual amount of plutonium produced under the most ambitious
nuclear power production program conceivable.”

The fact that thousands of other chemicals and metals are also extremely
toxic does not make nuclear radiation less dangerous — but an exaggerated
fear of nuclear radiation while showing little concern for the other
equally toxic substances that exist within and around our communities
is what makes the fear of nuclear energy irrational.
If you want an expert’s opinion of the psychology behind the irrational
nuclear fears, take a few minutes and read A
PBS interview with Dr. Robert DuPont, a psychiatrist and expert
on fears and phobias who has studied and analyzed social perceptions
of nuclear
energy.
— Dr. Robert L. DuPont is a practicing psychiatrist
and a clinical professor of psychiatry at Georgetown University School
of Medicine. He is also the author of “The Selfish Brain: Learning from Addiction” and “Nuclear
phobia—phobic thinking about nuclear power: A discussion
with Robert L. DuPont”.
“…Nearly everyone agrees privately that safe disposal of
spent fuel or other high-level radioactive material is not a technical
problem, but a political one… If one accepts the view apparently
held by the majority of scientists working in the nuclear waste field
that public apprehension regarding the problem is grossly exaggerated,
then it is reasonable to ask how this condition came to exist. How did
the myth evolve? …the public has been rational. Their fears and
apprehensions are understandable, given the information available to
them.
“ In ancient times, myths (beliefs not necessarily based upon fact)
became embedded in the folklore of a culture over long periods of time
by passing from generation to generation. Often such myths were embellished
and amplified with each passage. Laws and rules governing society, such
as the witchcraft laws in colonial America, were predicated on such beliefs
since they came to be regarded as fundamental truths. Today, in the age
of mass communication, myths can become established far more quickly.
The advent of science during the last few centuries may have had a mitigating
effect on adherence to mythology, particularly in modem societies, but
this is by no means always the case. The folklore regarding nuclear waste
presents a particular case in point where beliefs, not supported by science
and logic, have played a major role in the development of our policies,
rules and laws.”

Nuclear Waste Disposal: the Nature of the Problem
“Opposition to nuclear energy is based on irrational fear fed by Hollywood-style fiction,
the Green lobbies and the media. These fears are unjustified, and nuclear energy from its start in 1952 has
proved to be the safest of all energy sources. We must stop fretting over the minute statistical risks of cancer
from chemicals or radiation. Nearly one third of us will die of cancer anyway, mainly because we breathe air
laden with that all pervasive carcinogen, oxygen.”
— Nuclear
power is the only green solution By Dr.
James Lovelock, preeminent world leader in the development of environmental
consciousness, originator of the Gaia hypothesis.
We need nuclear power, says the man who inspired the Greens
We need nuclear power, says James Lovelock, the man who inspired
the Greens. “We
reject nuclear energy with the same unreasoning arguments that our
ancestors would have used to reject geothermal energy, the effort
to harness the
heat of the Earth. Compared with the imaginary dangers of nuclear power,
the threat from the intensifying greenhouse effect seems all too real.
I wholly support the Green wish to see all energy eventually come from
renewable sources but I do not think that we have the time to wait
until
this happens. Nuclear power is unpopular but it is safer than power
from fossil fuel. The worst that could happen, if Chernobyls become
endemic, is that we live a little less long in a mildly radioactive
world. To me this is preferable to the loss of our hard-won civilization
in a greenhouse catastrophe.
“Nuclear electricity is now a well-tried and soundly
engineered practice that is both safe and economic; given the will
it could be
applied
quickly. It is risky if improperly
used but, even taking the Chernobyl disaster into account, it is, according
to a recent Swiss study, by far the safest of the power industries.
Disinformation about its dangers sustains
a climate of fearful ignorance and has artificially inflated the difficulties
of disposing of nuclear waste and the cost of nuclear power. If permitted,
I would happily store high-level
waste on my own land and use the heat from it to warm my home. There
seems no sensible reason why nuclear waste should not be disposed
of in the deep subducting regions of the ocean where tectonic forces
draw all deposits down into the magma.
“What stands against the use of
nuclear power are not sensible scientific or economic arguments but
a widespread, but unjustified,
public fear... The Greens have so frightened their supporters that
a change of mind would be almost impossible.
“The accident at Chernobyl is almost always presented as if it were the greatest industrial disaster
of the 20th century. Even the BBC, in a recent programme, stated that thousands had died there. Such
exaggeration suspends rational thought and is an unnerving triumph of fiction over science. In fact,
45 died at Chernobyl, according to the UN report on the disaster, and many of them were the firemen
and helicopter crews who tried to extinguish the fire. It was an awful event and should never have
happened, but it was far less lethal than the smog of 1952, when 5,000 Londoners died from poisoning
by coal smoke.”
