An Uncompromising Reality
“The discovery of nuclear reactions need not bring about the destruction of mankind any more than the discovery of matches.”
– Albert Einstein
What Kind of Obstacles Has the US Nuclear Industry Faced?
There are many reasons that this miracle of science has not flourished despite the wishes and intentions of people like John F. Kennedy and others.133 The lack of a standard nuclear reactor type. The decentralized political system. The uninformed public. The antinuclear lobby. A strict regulator. Political interference. Construction costs. The list goes on. But central to most of the road blocks is a lack of public awareness and fear of the unknown.
Einstein was intensely aware of his role in the creation of the atom bomb134, however indirect, but also of the benefits that this new science entailed whether it be medical breakthroughs or the generating of electricity. To his horror his discoveries not only held great promise harnessing of the atom for humanitarian benefits generating electricity and providing isotopes for medicine but also the atom bomb. In the quote above he is saying it’s what we do with technology that becomes destructive or beneficial. The choice is ours. Einstein also has been quoted about the capacity of human stupidity and I’m sure he would be sad to see how we have brought about climate change and its twin tragedy ocean acidification (more on this later) and plethora of other Earth maladies.
Our biggest problem is collective blindness. The willful ignorance is frightening. In terms of the probability for self destruction, it need not be nuclear weapons that destroys us, more likely, it will be our contribution to these Earth illnesses that finishes the job. The path we have taken is one of willful ignorance, neglect and indifference. As a civilization we continue to behave in the manner to which we have become accustomed, the same lifestyle that brought about climate change. Summing it up, our attitude of neglect, wastefulness, selfish pursuits of instant gratification, exploitation of resources, consumerism and hedonism have had an impact that seriously threatens human existence.
The role humans have played in affecting climate change and ocean acidification is pretty clear. We have all heard the warnings 135 and shrugged off responsibility. It has taken us a while to recognize the basic cause and effect of global warming. Mostly it is the direct result of fossil fuel burning. We have been asleep at the wheel. The burning of dirty coal not only produces CO2 but toxic substances and other greenhouse gases.

Also, burning gasoline and heating our homes with natural gas and oil seem like innocent activities to most, but collectively they are also emitting CO2. As a greenhouse gas CO2 is accumulating the fastest and is understood to be the most prevalent greenhouse gas. We are to blame because we continue to use these fuels. They have contributed to the constant building up of Carbon dioxide. (CO2) is the most plentiful of various greenhouse gases in the atmosphere (over 400 parts per million). The oceans have absorbed a lot of CO2 acting as a buffer. The natural ability of the oceans has prevented an otherwise much faster global warming, and consequently a lowering of the ocean’s pH level.
Awareness of the problem created by greenhouses gases is common knowledge but news of the backlog and future effects have snuck up on us.
What is the significance of the CO2 backlog?
Even if humans stopped causing CO2 emissions today the existing excess CO2 and the backlog in the air and oceans would take centuries136 or millenia to complete its natural cycle where it is returned to solid form in the ground and ocean floor. If by some incredible cooperative effort we somehow managed to stop burning stuff and stopped contributing to the existing trillion tons of CO2 not yet dissolved in the seas tomorrow, the warming it causes will not stop. Stopping all combustion would mean stopping coal and natural gas plants, commercial airlines, automobiles, industrial processes that use combustion, even your reading light by your bed could be powered by combustion if the energy comes from coal. It is not good enough to cut back. A reversal is what’s needed. All the coal, gasoline, coke, oil, biofuel, cement and steel production require combustion and that is exactly what needs to stop.
But many of these processes could be sustainable if they used nuclear power for electricity that would charge car batteries and the molten salt reactor possibilities of industrial heat to produce low carbon fuel and create better ways to accomplish common industrial activities.
When did the alarm bells go off?
Some scientists warned us. In fact one scientist who will come back to our story again. Alvin Weinberg, the inventor of the light water reactor and the molten salt reactor, predicted that our over use of coal could have serious consequences back in 1974.
The obvious early warning signs of the effects of climate and ocean change are rising sea levels. Parts of New York city have started flooding due to the constant rising. Sea levels have risen 70% more rapidly since 1993.137
In a video news release President Obama spoke of his plans for attending GLACIER138, a conference held Aug 30th, 2015.
“Climate change once seemed like a problem for future generations, but for most Americans it’s already a reality – deeper droughts, longer wildfire seasons, some of our cities even flood at high tide,” he said…In Alaska glaciers are melting… the hunting and fishing upon which generation have depended for a way of life and their jobs are being threatened.”
But the politicians are still playing politics. They can count on the fact that the public does not fully understand how extreme the problem has become. It is right to take action but the size of the problem continues to be swept under the carpet. U.S. diplomacy has failed in winning allies regarding fighting climate change. Stating that the problem is serious and then proposing countermeasures that amount to very little is a typically political maneuver. The reality is a pandora’s box, too big to confront and not within the scope of even one election cycle. To be set on a course of extreme action is just too big an issue for any future political leader to dare handle.
James Hansen of NASA Godard Institute for Space Studies started officially recording global temperatures on 1981. His most well known testimony before congress in 1988 did the most to raise awareness of global warming. He also wrote a paper in 2003 called “Can We Defuse the Global Warming Time Bomb?”

How We Measure Success
Most people would agree that technologically we, as a civilization, have come a long way. But if we were to measure how much of a difference any particular technology has made to our lives, nuclear technology might be the greatest of them all.
The engineers who designed and built the first nuclear reactors learned to apply science that was based on layers of engineering in many disciplines never seen before. They built the ultimate machine that could transform a “rock” into immense power. Power that could be extended, controlled and sustained for decades refueling once a year with some designs (i.e. CANDU) that never needed to shut down139 during refueling. The largest plants are strong enough to supply all the electricity needs of an average city. That rock was no ordinary rock. Some of the proposed 4th generation reactors we will see next decade will only need refueling every 4-7 years.140
The irony is that the same science that led to the atom bomb is the same science that could lead to a solution that saves us. We already know that nuclear medicine is a field that has saved millions. Nuclear power plants have been a very important substitute for polluting coal plants. That alone goes a very long way to providing part of the solution. The atomic age is here but not nearly at the level it could be. Looking at the science of using uranium for bombs and the science of using uranium for creating energy are two distantly related and very distinct disciplines. We can’t let our fear of nuclear bombs affect our path forward with nuclear power and nuclear medicine.(See Chapter Fourteen)
Wasteful Resource Wars Kill People and Costs the Environment
When you compare spending on defense and military between countries we can see that most of the biggest countries feel the need to protect their sovereignty. The US spends trillions on defense, spending that could otherwise go far towards solving the energy crisis for example or replacing coal with nuclear. The misguided funding of the government military and defense sucks the life out of the economy and the competing government departments who get stuck with comparably pitiful amounts.
Learning to Overcome Irrational Fear
The way James Lovelock describes the fear is that nuclear radiation is mistakenly connected to cancer141. We have all witnessed the effects of the disease. We live with a contradiction and most of us have witnessed that radiation can even cure cancer. We have been told it can cause cancer but, in truth, not so easily. Our bodies have evolved from a time when radiation was even greater than we now deal with in our modern daily existence. Remember that we have radiation around us all of the time. Our bodies deal with far more chemical assaults than radiation assaults. In fact many scientists have concluded that radiation below a certain level is actually beneficial. The common items we come in contact with daily do not harm us even though they emit radiation.
Things like bananas (any foods with potassium), granite, marble, the sky, the sun, the earth, the sand on the beach, the ocean we swim in all have radiation. You remember the nuclear bomb tests that took place in the ocean, the air, underground? (Some exceptions of course took place but even expert Richard Rhodes says its the fires that do the most harm142) But, how is it possible that we have not had massive illnesses from radiation exposure to fallout? The reason is that the radiation is diluted to levels that we already routinely deal with on a daily basis so it has no consequence. This is also true of rarely occurring nuclear accidents. In fact coal plants are far worse. Coal emits all kinds of toxins including, you guessed it, radiation. Keep in mind radiation has a halflife. It disappears eventually. The chemicals like mercury, sulphur and arsenic that are emitted by coal plants are forever.
From Innocence to Disillusionment
A lot happened in nuclear science while we were not looking (See Benefits of Nuclear Science in Chapter Twelve).143 It does raise some questions. What happened? What caused the industry to forge ahead scientifically without making the science and mathematics more accessible? How did the public’s grasp on the science become so distant?
Our fears have affected the outcome of the dream of an atomic age. Even the medical world has been affected by the attitude towards nuclear plants. Such a slowdown was triggered by unfortunate circumstances. As a result of misunderstood mechanical failures in two nuclear plants (three if you count the more recent Fukushima) the industry became heavily regulated, over politicized and over scrutinized in an already over-regulated industry.
The 1950s expanded and ushered in a real consumer and commercial age. It was a baby boom era that created a market frenzy that flaunted the products and lifestyle of the American dream. Images of stay-at-home housewives and the working husband became a frequent part of the ads in magazines and on sponsored television. Symbols of prosperity, innocence and hope clashed with those of the civil rights movement and the witch hunts against communists.
The depiction of the Russian adversary in films and news about a growing arms race heightened the fears. The rapid scientific advancement and military expansion on both sides as well as attempts to justify aggression both abroad and against the so-called communist sympathizers produced deep psychological damage that would have repercussions in more than just America. The Middle East, Korea and Vietnam all became the stage to play out the drama of building American military might and the policing of the free world against communist expansion.
Who Will Communicate Lessons Learned after the Silence?
A lot of traditional values slipped away when mass media started to dominate our daily routine. At first it felt good economically because people had plenty of disposable income. But a lot started to change as the period of innocence gave way to cynicism. We started to recognize hypocrisy. Woe had been raised on a phony ideal. What was labeled the “me” generation emerged. Divorces skyrocketed and children with single parents became quite common.
The ideal of being wholesome, law abiding and self sacrificing was the message coming from the establishment as to the best path to follow, but after experiencing a lack of similar sentiments in return we began to feel betrayed. The preaching and the doing has not been consistent. It has eroded our confidence in the system. But the system is supposed to be democratic. Do we let democracy perform as it should? How might our wishes be better represented? More on this later.
How Silence, Secrecy and the Cold War Stifled Progress
The roots of the problem that produced a generation of anti nuclear citizens began with the second world war, the Manhattan Project (1939-1946). It was a project to develop the atomic bomb. It was done in secret. The best scientists from around the world were assembled.
How it happened and why it happened is generally understood. It was wartime. But that secrecy is what drove a wedge between public understanding and scientific advancement.
A great deal was accomplished in those few years. A very large body of scientific discovery was known by only a limited number of people and kept secret for several decades.
Glenn Seaborg had started to report on the properties of thorium and uranium in 1939. His big breakthroughs in 1942 were with thorium and plutonium. Seaborg knew that he had made a startling discovery and saw its potential for powering electricity for peaceful purposes. But his discovery that Thorium could create Uranium 233 was overshadowed by his discovery of Plutonium.
Thorium had the promise of being used for peaceful purposes but the bomb fuel, plutonium, became the focus till after the war. Thorium became the motivating purpose for the molten salt reactor over a decade later under Alvin Weinberg’s Molten Salt Reactor Experiment (MSRE).
Ironically the military quest intervened once more in the late 40s when it was requested that a nuclear powered airplane be designed.
The years following the 2nd World War were generally positive about the prospects of an atomic age. The public had visions of a very modern and affordable future. But the contingent of an uncertain future with an aggressive Russian leadership kept the US military leadership on a continuous R&D effort to hold onto its military advantage. The next goal was the Nuclear Energy Powered Aircraft (NEPA) under General Curtis. He had commanded the bomber attacks on Japan during the war. Conceptually the idea was to be able to keep a nuclear bomber aircraft airborne indefinitely, unrestricted by fuel limitations. There were several designs being considered. The idea was tested for a short time and it was dropped and picked up again later.
Weinberg had a long standing position as administrator at the Oak Ridge National Laboratory from 1945 to 1973. Just like many of his colleagues he had worked on the Manhattan Project.
In Weinberg’s The First Nuclear Era he says “as I think back on Wigner’s design of the Hanford plutonium-producing reactors, I can think of only one analogy: Mozart, who would compose a piano concerto in a few days. The whole thing was accomplished in about four months…the entire conception was mind-boggling- a chain-reacting pile producing 500 megawatts at a time when no one had operated a critical pile at any power… we can hardly imagine the sense of strangeness that pervaded the enterprise in 1942.”
A smaller reactor was now being considered for flight. Weinberg knew it was not a smart idea for a few reasons but he welcomed a chance to develop the technology to become a better reactor than his first invention the Light Water Reactor (LWR) which eventually became a huge success on submarines and aircraft carriers and eventually civilian commercial reactors.
Since the light water reactor had been declared too heavy for flight a new design was requested and that is when the MSRE was born. What was called the Thorium cycle that produced U233 had been determined to be unsuitable for nuclear weapons.
But the design concept was radically different from any previous reactors. The fuel was blended with a molten salt mixture and it so happens that uranium 233 was the fuel of choice but prepared in a separate research reactor. The eventual development of thorium processing would depend on getting the green light to develop a commercial reactor. The thorium cycle produced U233, a fuel much less desirable for weapons, and it held the promise of a cheaper to build, more efficient and even safer reactor. Alvin Weinberg’s focus on reactor safety and his strong preference for the molten salt reactor designs went against the more favored nuclear design, the Light Water Reactor. It was what led to his being fired.
Much of the library at Oak Ridge National Laboratory (ORNL) consists of thousands of pages that remained classified until the 1990s. This whole field of science had stayed secret while a new generation of engineers and scientists knew very little about it. Glenn Seaborg referred to the secrecy of the time as “small islands of technical information sealed off from the rest of society.”
In a book titled “Neutron’s Children: Nuclear Engineers and the shaping of identity” Sean f. Johnston states “Previous studies of secrecy in the nuclear field have focused on those vocal and visible members of the ‘atomic scientists movement’ who actively promoted internationalism and progressive ideals during the post-war period, or on contemporary weapons designers. By contrast, the effects of secrecy on their cousins the engineers, technicians, and other skilled nuclear specialists, who arguably were even more affected, kept them relatively voiceless and unexamined.” … “Like medieval monasteries, wartime and post-war national laboratories in the USA, UK and Canada promoted distinct regional variations, they were not founded primarily with economic motivations, but on locally nuanced and isolated intellectual foundations; they combined idealism with pragmatic duties; and they served a strong central authority.”
The knowledge gained from developing and processing the fuel for weapons during those early war years prepared the way for commercial reactors. But the secrecy caused a gap in understanding which led to the myths about nuclear energy and atomic science. This grew into a backlash that prevented us from benefitting from the full potential that nuclear technologies capability promised.
The quest for military power and the propaganda machine was certainly an obstacle. Various leaders and men in positions of power took on roles that were strategic for developing a superior military force and providing a technical knowledge that unintentionally became a part of a knowledge resource for positive change. President Harry Truman back in 1946 wanted nuclear research out of the hands of the armed forces and switched to civilian hands. This was a controversial issue and remained a divisive issue for decades to come. The Eisenhower years also started an initiative around the need for expanding nuclear energy with the Atoms for Peace program. Kennedy, Johnson, Nixon and Reagan had positive outlooks for nuclear energy. But not enough to stay the course.
There were other factors, such as the hubris that accompanies any specialized field, that played a role in causing the delay of nuclear science advances reaching the public as well as contributing to a growing mistrust of scientists.
Science has grown and fragmented into an unimaginable number of fields and specialties. This trend has blossomed to a point where any member of the public is challenged to keep up. But energy is fundamental just like food and money. So the basics of energy need to be learned early. Now more than ever nuclear energy must play a role in restoring Earth to an ecological balance.
In light of this we need to understand what other obstacles also prevented acceptance of nuclear energy. These obstacles have their roots in anti nuclear groups and individuals. The original antinuclear groups never confused the two technologies of nuclear weapons and nuclear energy. They simply wanted to ban the bomb. But with growing consumerism and personal possessions adding two or more cars per household began to make the oil companies very wealthy. They were so huge and wealthy that they made the nuclear companies seem commercially insignificant. But for the oil companies it was the prospect of nuclear energy taking some of their valued business away.
So joining the propaganda effort were the corporations who saw nuclear energy as a threat. On one hand you had the propaganda justifying the war machine and on the other you had a rationale designed to slow down or stop nuclear energy in order to ensure continued profits from oil and coal.
In conclusion a lot of the blame for the sins against the environment sits with corporate greed, the military complex and the growing gap between the public and scientific community. We can begin to see that turning a blind eye to important trends had repercussions. To ignore the warnings of people like Alvin Weinberg who wanted a better nuclear reactor that was potentially cheaper and safer and therefore more able to bring on the atomic era was a sensible vision in retrospect. Knowing that climate was changing was not a major concern for very many.

I write to you for help at the suggestion of a friend.
Through the release of atomic energy, our generation has brought into the world the most revolutionary force since prehistoric man’s discovery of fire. This basic power of the universe cannot be fitted into the outmoded concept of narrow nationalisms. For there is no secret and there is no defense; there is no possibility of control except through the aroused understanding and insistence of the peoples of the world.
We scientists recognize our inescapable responsibility to carry to our fellow citizens an understanding of the simple facts of atomic energy and its implications for society. In this lies our only security and our only hope — we believe that an informed citizenry will act for life and not death.
We need $1,000,000 for this great educational task. Sustained by faith in man’s ability to control his destiny through the exercise of reason, we have pledged all our strength and our knowledge to this work. I do not hesitate to call upon you to help.

He stated that a doubling of global carbon dioxide emissions by 2025, which some scientists predicted would occur, would lead to a two-degree Celsius increase in global average temperature.” https://www.revolvy.com/main/index.php?s=Alvin%20M.%20Weinberg

Edward Teller warned the oil industry in 1959 – “Ladies and gentlemen, I am to talk to you about energy in the future. I will start by telling you why I believe that the energy resources of the past must be supplemented. First of all, these energy resources will run short as we use more and more of the fossil fuels. But I would […] like to mention another reason why we probably have to look for additional fuel supplies. And this, strangely, is the question of contaminating the atmosphere. [….] Whenever you burn conventional fuel, you create carbon dioxide. [….] The carbon dioxide is invisible, it is transparent, you can’t smell it, it is not dangerous to health, so why should one worry about it?
Carbon dioxide has a strange property. It transmits visible light but it absorbs the infrared radiation which is emitted from the earth. Its presence in the atmosphere causes a greenhouse effect [….] It has been calculated that a temperature rise corresponding to a 10 per cent increase in carbon dioxide will be sufficient to melt the icecap and submerge New York. All the coastal cities would be covered, and since a considerable percentage of the human race lives in coastal regions, I think that this chemical contamination is more serious than most people tend to believe.”
“At present the carbon dioxide in the atmosphere has risen by 2 per cent over normal. By 1970, it will be perhaps 4 per cent, by 1980, 8 per cent, by 1990, 16 per cent [about 360 parts per million, by Teller’s accounting], if we keep on with our exponential rise in the use of purely conventional fuels. By that time, there will be a serious additional impediment for the radiation leaving the earth. Our planet will get a little warmer. It is hard to say whether it will be 2 degrees Fahrenheit or only one or 5.
But when the temperature does rise by a few degrees over the whole globe, there is a possibility that the icecaps will start melting and the level of the oceans will begin to rise. Well, I don’t know whether they will cover the Empire State Building or not, but anyone can calculate it by looking at the map and noting that the icecaps over Greenland and over Antarctica are perhaps five thousand feet thick.” https://www.theguardian.com/environment/climate-consensus-97-per-cent/2018/jan/01/on-its-hundredth-birthday-in-1959-edward-teller-warned-the-oil-industry-about-global-warming
