Since my sincere and deepen devotion from 1996 , ”l’ve written
five books and numerous technical papers and popular articles about nuclear civil
use and the related myths v/s reality. In my research, I’m repeatedly by the
inconsistencies, contradictions and questionable logic that characterize its
literature, including statements that are presented as scientific fact but are
demonstrably false. Anything nuclear is repeatedly charactised as “scary,”
“dangerous,” and “hazardous,” yet the actual health statistics show nuclear
workers among the healthiest. These contradictions and mis-statements have
become part of the legend and culture of the nuclear enterprise, on which we
all-insiders and out-base our opinions and decisions. How did this happen, and
what should we do about it. Let’s start at the beginning. Most people learned
about nuclear fission from the fiery destruction of two entire cities. Although
most other large Japanese cities had destroyed by firebombs, this was
different. The degree of destruction was comparable. The mechanics of
destruction-heat and physical blast-were comparable. The uniquely nuclear
feature-radiation- was trivial, by design. But, for military and political
reasons, it was important that nuclear weaponry be seen as the ultimate doomsday
super weapon so uniquely fearsome that no merely human army could stand up to
it. That fear-generating ability was carefully nurtured through the
duck-and-cover drills of the cold war that followed, in the tactic called “MAD’’
(Mutually Assured Destruction). Each party kept reminding the other a breach of
the treaty would surely bring about the end of civilization.
The New World
Out of this uneasy uniqueness, the
Nuclear community undertook the
creation of a new and esoteric Nuclear World-a kind of a Fantasy Land, where
200 years of mundane engineering experience and judgment seemed wholly
inadequate. In the 1970s, New Age gurus from Baba Ram Dass to Margaret Mead told
young people that their elders had not experienced the coming age, did not
understand it, and therefore could not advise them on how to live in it.
Experience in the dying age was declared inapplicable to the New World. At the same
time, nuclear gurus were applying the same philosophy to the Nuclear Age. Alvin
Weinberg, long-time senior spokesman from Oak Ridge, characterized nuclear
energy as a “Faustian Bargain”-a providential gift to humanity, but with the
Devil to pay if we slip up. To keep nuclear technology from slipping inexorably
into mediocrity, we need to keep the Faustian threat alive.” Rickover had
created the American nuclear navy, and he certainly agreed with the need for
unprecedented excellence-indeed, he practically created it. But he believed
that excellence was justified on its own merit, and didn’t need a satanic myth
to support it. Then, in 1953, U.S. President Eisenhower launched his atoms for
Peace program; the Friendly Atom was to take over from the fearsome A-bomb.
Eisenhower wanted to have his Atoms for Peace program completely civilian, but
the only group ready to take on such a major chore was Rickover’s Naval
Reactors group. So Eisenhower assigned Rickover the job of building the world’s
first wholly commercial central station nuclear power plant. All the supporting
technology was to be rounded up, declassified, and submitted to civilian
engineering code committees. Fear and mystery would no longer be an integral
part of nuclear technology. Rickover was to build an engineering world to help
the Atom join the civilian labor force. The declassification order was carried
out swiftly and completely. When the plant was built and operating, Rickover
showed Frol Kozlov, the USSR second-in-command, through it. When Kozlov asked
Rickover, on public TV, where to leave his camera, Rickover said he was welcome
to photograph anything in the plant; there was no classified information in the
entire facility. But of course, it was not quite so simple to bring about such
a complete reversal of mindset in the public, or even within the nuclear
community. Most people had been quick to accept that the Atom was fearsome, and
now they were reluctant to abandon that belief. When it became apparent that
they might have to take the Atom into their homes, they started expressing
concerns and raising questions. For many, these concerns have still not been
satisfactorily answered. Yet, it is not hard to show that most of these fears
are based on premises that are simply
untrue, and others are based on theoretical computer models that describe
situations that simply cannot occur in the real world. Let’s look at some
specifics, one at a time.
A Quick Look at Nuclear Power “Problems”
Myth: It’s better
to use a biofuel, because it’s renewable and sustainable. In fact, biofuels
raise more uncertainties and known problems than nuclear fuels. That’s because
biofuels need huge quantities of materials in demand elsewhere. We’ve already
seen what happens to the price of food, when even a small amount of corn is
diverted to ethanol production. If cornhusks, switch-grass or other fibers can
be used instead, their diversion from soil nurture is apt to have serious
consequences. Nuclear fuel requires less than a millionth as much material, and
it’s not a material vitally need in the consumer market. Only one in 140
uranium atoms is fissionable that is, fuel. The other atoms are “fertile,” that
is, capable of converting to fuel by absorbing a neutron if the fuel is
recycled. We are in future recycling fuel and India is going to lead the whole
world in this field. As we go into recycling and then breeder reactors, we can
eventually tap the seawater, in addition to hundreds of years of mineable
uranium, the oceans contain an estimated 4 or 5 billions tons of uranium, which
is continually replenished as uranium is leached from ocean life -forma and
from the land, by the rivers emptying into the sea. In addition, there is
nuclear energy available from thorium, which is several times more abundant
than uranium. (Some or all of India’s new reactors will probably be based on a
thorium cycle.) Like the non-fissile uranium, thorium can capture a neutron and
produce nuclear fuel. That can create a reliable energy source for millions of
years. (India has its own, homegrown way of introducing real-world technology
into the nuclear world. Drawing on lessons from the Swedish Movement, which it
has used so effectively in dealings with other nations, India is buying nuclear
technology from more than one nation, with the intent of developing full capability
to build nuclear power plants of local design, with no outside assistance. True
swaraj!
But How Do We Solve the Nuclear Waste problem?
We created this problem. I’m not referring to
fission products. Fission products are not a problem. They’ve never been
released in dangerous quantities into the environment. They’re still bound
within the refractory ceramic fuel pellets where they were formed. These
pellets are inside stainless zirconium tubes that are sealed into
high-integrity used-fuel casks, which are nearly indestructible. These casks
sit in water pools for several years, until more than 99% of their
radioactivity dies out. Then the casks are removed from the water until they
are recycled to recover most of the fissionable material still in them. Right
now, it’s cheaper to keep using new uranium, but eventually they will all be
recycled. They’ ve been sitting there up
to half a century, hurting no one, having no impact on the environment. They
could stay there another century. Some plant owners invite the public-school
children, church groups, scout troops- to visit and see these casks, touch
them, measure their radiation level, to understand firsthand that these casks
are neither mysterious nor dangerous. We’re the ones that keep telling people
there’s a problem. Anti-nuclear activist, Sheldon Novick, wrote that nuclear
waste is no more hazardous than many other industrial wastes. During the first
decades of nuclear power, there was no demand from the public to move the
waste, until Nuclear Energy Institute (NEI) took out full-page ads in major
papers telling people that used nuclear fuel casks were terrorist targets. This
created the “Mobile Chernobyl” problem. We also kept telling people that our
most important problem was getting the nuclear waste storage site at Yucca
Mountain (YM) approved. It’s true that the federal government by law is
supposed to take responsibility for the waste, but this is not because of its
special danger. The only way to solve this problem is to tell the truth: is no
such problem. The quantity of material is trivial. Its toxicity is comparable
to other, non-nuclear wastes that we deal with routinely except that it gets
less and less toxic each.(How is that a problem\) No one has been injured, or
even in danger of being injured, nor is there any objective evidence of
environmental harm. So long as we keep telling people “we have to figure out
how to solve the waste problem,” we make it so. This “problem” provides income,
reputation and jobs for many people. But so does building and operating nuclear
power plants. We need to stop working on problems that aren’t real, build
plants we know how to build, and keep looking for ways to make plants better
and better. We need to do all three.
Why Treat
Nuclear Assets as Fearsome Problems?
In trying to think rationally about the many
contradictory statements and actions associated with nuclear power, one useful
tool is the concept of reduction ad absurdum. This rule of logic says to follow
a particular line of reasoning until either the problem is solved, or an
absurdity is encountered. But
This approach fails when one cannot recognise
absurdity For example, suppose one postulates that nuclear waste is so
dangerous that extraordinary actions must be taken to keep it from being eaten
(the only way it can be hazardous). Following that premise, we could put the
waste into sealed canisters, with great care taken in design and material
selection, and announce that the problem is solved. With this in mind, let us
look at some of the myths that have been developed to claim that nuclear technology
is uniquely hazardous. To understand the situation, we must recognize how these
myths arose and how they are sustained. First: antinuclear activists did not.
Jane Fonda did not invent The China Syndrome, Nor did the media. We did. So we
should not complain that we cannot get our message out. We’ve gotten it out
very well. We’ve said for fifty years that is no safe level of radiation, that
nuclear waste is a major (perhaps insoluble) problem. Further instruction in
public relations will not solve this problem. We must first get a clear picture
of what is so and what is not. Let’s start with an easy one:
Myth: Nuclear are potential nuclear bombs. Even
shipments of spent fuel are “mobile ChernobyIs.”
Facts: is simply untrue. No shading or ambiguity about
it. We should have no hesitancy in asserting that the Laws of Nature prevent
accidental criticality occurring in such cases.
Myth: nuclear power
is an especially unforgiving technology. A momentary slip-up, and it’s
catastrophe.
Facts: the opposite is true: nuclear plants are robust
and stable. Hundreds of commercial nuclear power plants worldwide, and hundreds
of naval reactors operating reliably for decades, confirm this. They can resist
earthquakes, hurricanes, power loss, sabotage, and operator errors. Ironically,
although nuclear plants are designed to operate reliably under conditions that
destroy, or shut down, other facilities, a distorted sense of caution requires
that they be shut down just when they needed most! This may be another case
where purported safety rules actually actually lead to a less desirable
situation. The proven stability of nuclear plants spawns the next myth:
Myth: Nuclear
plants are so touchy; they use them only for providing the steady base load.
You wouldn’t want to try load-following with a nuclear plant.
Facts: This is a wonderful example of portraying a
nuclear asset as a problem. Nuclear fuel is cheap; building a nuclear power
plants is expensive. So, once a plant is built, it makes economic sense to use
the cheapest fuel as much as possible, and bring in the cheap gas- fired plants
that burn expensive fuel only when you have to. But it’s the steam plant, not
the nuclear plant that limits how fast you can maneuver. The flexibility and
responsiveness of a nuclear power plant is dramatically demonstrated in a
working nuclear- attack submarine. Admiral Rickover used to challenge the crews
to see how fast they could change power level. They would select the biggest,
strongest sailor aboard, and pass the order, “Crash back!, ”which is a maneuver
that takes the ship from “All Ahead Flank!” to “All Back Emergency!” The sailor
spins the ahead throttle closed bringing the reactor from 100% power to zero.
He then immediately opens the astern throttle as fast as possible, restoring
the reactor to 100% power. The ship shakes violently, shrieks of various
equipment protesting mix with the clatter of coffee cups, operating manuals and
other miscellany sliding off normally horizontal surfaces, as the ship shudders
to an emergency stop. The reactor plant operator watches placidly as the
reactor temperature drops a few degrees, which automatically raises the power
smoothly to the required level. He could pull the reactor control rods a notch
to restore the temperature, but he doesn’t have to. The electrical plant
operator and the steam plant operator are equally relaxed, as the ship’s
propeller reverses, and the plant accommodates itself to the new conditions.
Lt’s hard to imagine the need for any greater flexibility than that. Unlike a
combustion-fired power plant that has to warm up and cool down very carefully,
to avoid thermally shocking the system, the temperature swings in a
water-cooled plant are quite moderate, and impose no restraints on the
operators.
Myth: We should
stop creating all this radiation and radioactivity. It’s unnatural,
little-understood, an unprecedented, ever- growing threat to the natural earth.
We’re fouling our nest and degrading the human gene pool by continually adding
to the earth’s radioactivity.
Facts: Radiation has been with us since the dawn of
time. Evolved in a sea of radiation several times more intense then than it is
now Our soil, water and our bodies are naturally radioactive. Radioactive
processes light the sun and stars and keep the earth’s core molten and our
environment livably warm. Radiation is better understood that. Most
environmental challenges. Tests report NCRP-136, by the U.S. National Council
on Radiation Protection and Measurement, states right up-front (page 6) that
most people exposed to low-dose radiation are benefited, not harmed by it. Fission
changes long-lived uranium into shorter-lived fission products, ultimately
decreasing earth’s radioactivity. All the radioactivity we generate is not
enough to offset the earth’s natural radiation decay. The earth becomes less
radioactive each year.
Myth: But radiation
is spooky. You can’t see it or smell it. You can’t tell it’s there until it’s
too late!
Facts: Radiation is detectable at the single atom level
by a simple, hand-held detector. No other hazard is so easily detected. As the
respected physicist/ physician, Zbigniew Jaworowski, wrote, humans and other
animals have no organs for sensing ionizing radiation, because they have no need
for them. Natural radiation up to hundreds of times the levels now being
regulated have proved to be harmless, or even beneficial, as noted above. Myth: we don’t know how to solve the waste
problem. The quantity of nuclear waste is so great and we don’t know what to
with it!
Facts: Not true! In every real sense, we handle the
problem before it begins. Nuclear plants produce less than one-millionth the
volume of waste from an equivalent coal-fired plant, so it can be put into
sealed, stainless steel containers and controlled, rather then dumped into the
environment. The 50.000 tons of radwaste destined for a federal repository was
produced by all U.S. nuclear plants over the past 40 years. This is less than 2
pounds per person served. You could put each person’s lifetime of nuclear waste
into a soda pop can. So it’s no problem to keep it in casks and never dump it
into the biosphere. The corresponding waste from a coal-fired plant is 140000
pounds. U.S. Naval reactors can now operate for the life of the ship-a million
miles, without refueling. All the waste from that operation stays locked up
within the fuel elements, without causing any undue swelling or distortion.
That illustrates the small quantity of waste we’re dealing with. Compare that
to wastes produced by other industries. Even the volume of waste from
construction & operation of solar, wind and other renewable is greater on a
per-kilowatt-hour basis than nuclear, and some of the solar power poisons and
highly toxic forever.
Myth: What about those huge waste tanks that have been
leaking radioactivity into the ground for years?
Fact: Those tanks, at the Hanford site in the state of
Washington, were built during World War II, to handle liquids used in the
Army’s Manhattan Project to build the atomic bomb. They have nothing to do with
the commercial nuclear power plants. If no nuclear power plants had ever been
built, the situation of Hanford would still exist. We’ve learned a lot since
then, there are no such tanks associated with the commercial nuclear plants.
Incidentally, Hanford is now being cleaned up, and there is no evidence of danger
to people or to any of the surrounding environment. The phrases “exposed to
radioactivity” make exciting headlines, but it is not evidence of bodily harm.
We are all exposed to radioactivity, every day and night, and it does us no
harm.
Myth: Nuclear waste stays toxic for thousands of
years. Humanity has never faced such long-term hazard. Anthropologists have talked about setting up
a “nuclear priesthood” to pass on word of where radioactivity is buried. So as
civilizations rise and die out, people a million years from now will be warned
to stay away.
Facts: All radioactive materials continually decrease
in toxicity, whereas non-radioactive pollutants like mercury, lead, arsenic,
selenium, cadmium, chromium,etc. maintain their toxicity undiminished forever. After
a few hundred years, nuclear waste is no more toxic than the original ore, yet
we plan to bury it 1,000 feet underground. We make 10,000 times more lethal
doses of chlorine each year and put it in our drinking water to kill germs.
Myth: Shipping
spent fuel casks past school and homes is a terrible risk.
Facts: These shipments pose no realistic risk
whatsoever. The shipping containers are nearly indestructible. They have been
tested by high-speed collisions, and fire. The fuel and waste are solid and
there is on liquid to leak. It can’t “go critical” like a reactor. In tests. A
special armor-piercing missile was mounted on a cask, to ensure that it would
hit exactly on the centerline and not be deflected harmlessly aside. It blew a
small hole in one side of the container, but the small amount of radiation
released would not be harmful. The diesel fuel in the truck’s “gas tank” would
be a greater risk than the waste cask, although it is on more dangerous than
any other truck.
Myth: The Chernobyl accident in 1986 killed thousands
of people and disabled millions.
Facts: Not true. Fifty workers and firefighters at the
plant were killed. A 20-year investigation by the U.N. and World Health
Organization concluded that no members of the public were harmed. There were
about 2,000 cases of childhood thyroid nodules, with 10 or 12 deaths resulting
from this condition. But the occurrence of these doesn’t correlate with
radiation level, and are within the natural occurrence frequency for such
nodules nodules. The World Health Organization (WHO) said that fear of
radiation caused much more harm than radiation itself. It led to unnecessary,
long-term evacuation of large population groups, 100,000 unwarranted
“voluntary” abortions, unemployment, depression, alcoholism and suicides.
Deformed “Chernobyl victims,” displayed to raise money for relief efforts
suffered from conditions that were later shown to be unrelated to the accident.
Some were from far away; others were deformed before the accident. Chernobyl
not a factor in their condition. In any event, no one is suggesting that more
Chernobyl reactors be built. It was a flawed design, built and operated without
adequate safety considerations. The water-cooked reactors of the king now
operating could not under undergo the type of casualty that occurred at
Chernobyl. Let us look at the fundamental
question about the safety of nuclear power plant: How bad could a worst-case
nuclear casualty be? Many theoretical studies have claimed that a hypothetical
mishap could cost thousands___ even hundreds of thousands ____ of lives.
Nuclear advocates reply that the particular casualty described is “a highly
improbable scenario” and therefore an acceptable risk. Such a response___ that
this sort of thing will not happen very often__ does not answer the question.
Highly improbable events do happen. How bad could it be? And what about
scenarios not yet envisioned? We deserve substantive answers to those
questions. Putting extraordinary
emphasis on safety without defining the hazard is misleading and irresponsible.
It is easy to calculate what would happen if all of the radioactivities in
a nuclear reactor were released into the air at once, and it stayed suspended
in the air over large areas and populations, and that any radiation exposure is
detrimental. Such calculations say that thousands could die. But such a situation cannot be created in the
real world. “Worst case” calculations are not meaningful if they are based
on conditions that defy the laws of nature and the known properties of
materials and processes. What is relevant are credible engineering evaluations
of the consequences of the worst conditions that could realistically be
created, based on known science, both at the laboratory level and from
large-scale tests and analyses. This has been done for pressurized water or
boiling water reactors, of the type now operating in nearly all the world’s
commercial nuclear power plants. Similar analyses of the Canadian CANDU
reactors show that they have an even larger margin of safety. The worst
consequence of any postulated scenario would begin with a loss of the water
that cools the fuel, leading to some molten fuel. So we can presume (for the worst case) that a large part of the fuel melts. Then we
need not argue what scenario could get us there. We’ve accepted the worst case:
fission products from the fuel escaping into the coolant. We assume further
that the coolant system boundaries are
compromised by the casualty, and fission products are escaping into the
containment atmosphere. We know the rate
and the composition of fission products released by molten fuel. Starting
in the 1950s, extensive theoretical and laboratory work was done worldwide to
explore these questioned, and we know that in all of the real reactor
accidents, measured releases were very much lower than the unrealistic
assumptions used for safety studies. And we know what happens to fission products as they enter the air, steam and water
surrounding the reactor coolant system. We have substantial field data
showing that highly charged and reactive fission product particles rapidly
clump together and accumulate in the water flows and settle in the sumps, are
absorbed in steam and water, condense and plate out on cooler surfaces, and
interact with other materials they contact. The water lost from the reactor
cooling systems does not disappear; it does not all evaporate inside the
building. It reduces the airborne radioactivity within the building many
thousand-fold below the extreme assumptions used for some safety analyses. So
we assume that the worst realistic casualty also compromises the containment’s pressure-retaining ability and
leak-tightness, so it is no more effective a containment structure than other
industrial buildings, which, it turns out, is good enough.
Other
means of generating electricity have occasionally caused death and bodily harm.
Nuclear Power has not. In this situation, it does not make sense to require
nuclear plants to protect against hypothetical dangers, while not applying the
same amount of concern to more dangerous, and more vulnerable, facilities (oil
refineries, chemical plants, coal mines, and chlorine tanks.)
Unwarranted
fear of nuclear technology is based on two false premises: The belief that a
nuclear casualty could have catastrophic public health consequences, and The
belief that no amount of radiation can be small enough to harmless. These and
other false beliefs are accepted uncritically because nuclear power is demonised,
and e a r t h l y Solutions considered inadequate by definition. To make
progress, we have to apply real-world knowledge and experience, not unrealistic
models. To build a solid technology, quickly deploy many proven plants with few
regulatory questions; and start
preparing improved designs for regulatory review and approval and carry out an appropriate level of
long-range research to ensure continuous progress.
