Burning Warheads as Fuel for Nuclear Reactors?
Mary Olson with Jackie Cabasso
The disaster at Fukushima makes it
apparent how little is known about the operation of a nuclear power plant. For
example the so-called "spent" fuel in the cooling pools on the rooftops
is many times more dangerous than the fresh, non irradiated fuel. The biggest
danger from the Fukuchima nuclear accident comes from unit 3 that was stocked
in September 2010 with MOX, a new mixed oxide reactor fuel that contains
plutonium - not as a fission byproduct - but from the outset inside the fuel
rods. MOX fuel is many times more lethal than uranium fuel.
This is conversation between Mary Olson from NIRS, the Nuclear
Information and Resource Service, and Jacqui Cabasso from the Western States
Legal Foundation. It is a rare historic document of the origins of a campaign
against MOX plutonium fuel for nuclear power, an analysis of the terrible pact
of mutual support between utilities, weapons makers and bought off congress
people.
President Obama says, after
Fukushima, that nuclear power will remain quote "part of the overall
energy plan". Republicans - in their merciless budget cuts leave as yet a
program untouched that funds the ongoing construction of a MOX fuel generating
plant at Savannah River in South Carolina.

JC: Why don't we just back up a step and talk
about nuclear fuel and nuclear reactors. Just the real basics. Where does
uranium fuel come from and how is it made into fuel for nuclear reactors and
what does it mean when fuel becomes "spent".
MO: These are all good questions but we have to
start with that word "spent". The only thing spent about anything
nuclear is the money. There is nothing spent about what is properly called
irradiated fuel and that is the end point of your question. It's the fuel once
it's been used by the reactor to generate electricity. Let's start with that
point for just a moment. When atoms are split out come a tremendous amount of
energy, part of which is converted almost immediately to heat. And the heat is
siphoned off through the liquid coolant and turned into steam and the steam is
used to turn turbines that make the electricity. (So we think of reactors as
really just very fancy teapots. And the atom splitting is doing nothing more
than generating heat.
But that is a false picture because) At the same
time it's generating massive amounts of new radioactivity. As you ask –
where does this fuel come from? Uranium is an element that is in the earth.
It's mostly buried deep in the earth because life itself doesn't need it and so
the soils have built up on top of it. It's not been in the cycles. Human beings
go out and dig it up.
It's processed in many steps. It is radioactive;
it is a health hazard. The miners who dug up the uranium have suffered greatly
in their health, particularly lung cancer. The communities that have been
affected by mining and then the various steps of processing because uranium has
to be very highly processed to make fuel for reactors through six separate
steps including turning it into a gas and concentrating it into a particular
type of uranium which is the same one that can be used for making nuclear
bombs.
But in a reactor situation it's in lower
concentrations. So once this uranium is processed it's turned into fuel rods
and those fuel rods are moved around the country to the 103 reactor sites and
they are radioactive. But I have to tell you my dear sweet mother had the idea
that somehow the radioactivity was used up when the electricity was made and as
I said, when the uranium is put into the reactor the splitting of those uranium
235 atoms actually makes new radioactivity and that fuel becomes millions of
times more radioactive than the uranium that came out of the ground and in the
course of about 3 years - they are trying to make that longer - the fuel has to
be taken out because it has becomes so full of what is called fission products
which are the cesium the strontium, radioactive iodines, all of these different
radioactive elements get in the way of the fuel generating the heat that is needed
and so it is removed and the industry now calls it "spent" fuel.
And as I said it's now very expensive stuff, it
has to be safeguarded it has to be kept from melting; the heat from radioactive
decay that continues even after it is taken out of the reactor core is so great
that the fuel itself will melt if it not cooled for at least 5 years in liquid
and even after that it will spontaneously combust. And so this fuel made from
uranium is really very nasty stuff.
And the other thing that we need to point out is
that when uranium is put into a reactor, plutonium is formed in the process of
using the uranium fuel. Every single reactor on the planet that uses uranium
fuel generates new plutonium. And so in the U.S. our reactors generate about 1%
of the total weight of fuel by the time it is taken out is now plutonium. So
indeed the largest stock of plutonium in the world is in used reactor fuel or
irradiated fuel. I should stop and you should ask me another question but I
want to point out that in other parts of the world that plutonium is harvested
from reactor waste. We haven't been doing that in the US. We've been simply
storing the fuel as a waste.
(And I think it is important to underscore that
the language that the government and the nuclear industry use to describe its
processes is very, very misleading. Spent fuel sounds like it is harmless it's
actually even more dangerous than the fresh fuel. So we are not talking here
about the disposition or disposal, - also loaded words - of the uses fuel from
the commercial nuclear power plants. Now what we are talking about is something
new.)

JC: Isn't it true that the U.S. has historically
had a kind of firewall between commercial nuclear power and military nuclear
technology for bombs? And what we are talking about now is actually using
plutonium from dismantled nuclear weapons to burn as fuel in nuclear reactors.
Could you talk about that historic separation and what you see is happening
there?
MO: I want to just capture the moment to say that
the reactors were designed for uranium fuel. So one of the challenges we are
facing is a complete experiment of going to plutonium fuel. Now sadly it is not
all nuclear weapons and even more sadly there is lots of evidence that new
nuclear weapons are being made at the same time. Nonetheless it raises the new
question of what the hell do you do with the parts so that you can be sure that
they don't become nuclear weapons again. And I tell you right now that that's
what this whole program for plutonium or MOX fuel is supposedly about. It's
supposedly about making plutonium in the U.S. and in Russia from dismantled
nuclear weapons "safe". The sad thing is that not only is it making
nuclear power even more unsafe, it is also becoming a very thin cover over a
renewed nuclear weapons production program in the U.S.
So it is very difficult for me to give any
credibility to the idea that this program is in fact making anything safe. But
that's how it is being sold. Yes, there has supposedly been a great separation
between the production of nuclear weapons and the production of nuclear energy
- electricity. But I have to laugh at that too. Westinghouse built the reactors
for making electricity and Westinghouse got the contracts to make the bombs.
Where is the separation? General Electric built the other competing reactors,
the GE Mark I and Mark IIÕs that are no better than Chernobyl- have no
containment to speak of and undercut the Westinghouse model. They also for
many, many years were prime contractors on nuclear weapons. But in any case
there has been a supposed firewall.
Now what is changing and truly is changing is
that in the past nuclear power has enjoyed a lot of government support in its
development, in formulating insurance policy in case of major accidents called
the Price-Anderson Act; in nationalizing the waste program - so there have been
many supports for commercial nuclear power from the government.
But the plutonium fuel program will give them a
role in the National Security Mission and they will receive not only their
costs but direct compensation for performing this function and in an era of
supposed competition between different sources of electrical energy the
reactors that use the plutonium fuel will be effectively underwritten with U.S.
tax dollars, a check in the mail first time ever in order to keep the reactors
able to out-compete any other form of energy so that they can continue to
operate throughout the 20 years or however many years it take to
"dispose" of the plutonium.
MG: Can you give a quick definition of the
Price-Anderson Act?
MO: The Price-Anderson Act was an amendment to
Atomic Energy Act because commercial nuclear reactors could not find private
insurance for their operations. The insurance industry said: "No, we will
not insure you." And so the Congress stepped in and created a little funny
thing, and I'm putting it that way because I find it very interesting. There is
a pool of money that each reactor pays into every year that's about $100
million all told. If anything happens in the U.S. that costs more than $100
million all of the reactor operators that are licensed at that time to produce
nuclear energy have to pay equal shares and they do so every year for 10 years
and the current formula results in about $9 billion that would be a collective
payment by the industry towards the damaged.
Now, most reactor accidents would cost in the
hundreds of billions of dollars because they are close to urban areas. If you
wanted to calculate what would happen if Jumbo jets his the Indian Point
Reactors on the Hudson very close to where the World Trade Center was hit I
think it would exceed the $200 billion figure that I've heard floated. There
are three reactors at that site they've got close to 35 years of collective
fuel generation. The amount of radioactivity that would be floating around
Manhattan - that place would be a ghost town right now and the economic impact
on this country would be far reaching greater than Enron by many orders of
magnitude.
So the point here is that the industry all pay to
play one screws up they all pay but then they stop at about $9 billion, which
is a fraction of the true cost of a real Chernobyl style event in the U.S.
Chernobyl dumped the entire reactor core and contaminated vast areas of Europe
and even in the U.S. there was fallout. So the point is that they have limited
liability conferred upon them by law and the result is that the victims would
have to pay the rest. So ultimately those who would pay are those who would
suffer.
Now I want to say one last thing about this. The
plutonium doesn't go away. While the plutonium is in the reactor some of it is
split. It releases the energy that is the heat that makes the electric power.
Yes, but at the very same time mixed oxide fuel is made of both plutonium and
uranium. And the uranium in the fuel generates new plutonium at the same time.
So while the plutonium that is put in is reduced new plutonium is generated and
the net reduction is possibly 1 %. So this is not a way to get rid of
plutonium. It is only a way to making plutonium highly radioactive, which is
part of the goal of supposedly making it safer. A way to give tax dollars to
selected utilities that participate in a National Security Mission and prop
them up against any competition they might have -- and here comes the real
kicker -- re-purify plutonium to the point where it is so pure that weapons
designers or nuclear-fuel designers can use it.
That's why many organizations say that plutonium
IS a waste and should be treated as a waste and is not a fuel source and
certainly the experiment of using plutonium in Europe has shown that it is not
an economic fuel source. They are in debt in plutonium industries and they are
failing in Europe and indeed that's part of why they are coming to the U. S.
for our tax dollars to do this program to justify their expertise. But I want
to go back to the question, once it's in the reactor, why is it so dangerous?
Reactors are not safe. Uranium fuel is not safe.
There have been two major accidents and a lot of lesser-known accidents with
uranium fueling reactors - and speaking of Three Mile Island and Chernobyl. The
work has been done, the calculations have been made. If Chernobyl had had
plutonium fuel in the core, twice as many cancers would result. Twice as many
fatal cancers, twice as many non-fatal cancers. You infer therefore that all
the other health effects that come from radiation would also be twice as bad.
Why? Because not only is plutonium much more
effective at causing cancer, it's also very toxic and reactors that have
plutonium fuel in them not only make additional plutonium, they make even
heavier elements like americium and neptunium. You hardly ever hear about them,
but believe it or not, they're worse than plutonium for causing cancer and for
toxicity.
And so the reactor core is fundamentally changed
by introducing plutonium as a fuel. The consequences of a reactor accident are
fundamentally worse and there is every reason to believe that an accident is
more likely with plutonium in the core. And it's for precisely the reason that
plutonium-239 is selected for weapons production is because it likes to go
boom! - and is much harder to control than uranium. Uranium has a very
interesting attribute, which is the hotter it gets inside the reactor, the
harder it is to split a uranium-235 atom. It's a natural negative feedback loop
that allows the reactor operators to have a little bit of grace in their
ability to control a reactor core.
Weapons-grade plutonium - exact reverse. The
hotter it gets, the easier it is to split it.
The second attribute of uranium that helps the
reactor operators is when the atom is split, out comes that energy. Well, some
of the energy is in the form of particles that are highly charged called
neutrons. Uranium happens to have two releases - an initial one that's
immediate and a secondary one that is seconds to minutes later.
Reactors are controlled with something called a
control rod - many rods that are inserted. Well, they are mechanical mechanisms
that require seconds and minutes for them to move. You cannot move a control
rod in a nanosecond. It is not physically possible. Well, the weapons-grade
plutonium they want to put into these reactors as fuel has only one third as
many delayed neutrons. The second burst that comes out later.
So control rods are only one-third as effective
when you're using plutonium fuel. So the engineers, you know, they love to
solve all these problems. But every time there is a new problem and a new
solution, I believe - and many others believe - it cuts into what's called the
margin of safety. And so we have a fuel that's much more dangerous in terms of
the consequences. We have a fuel that's likely to cause an accident more
readily. And we're paying for it with our tax dollars.
JC: And I just want to talk a little more about
why plutonium is so dangerous. As you mentioned, when plutonium is in a metal,
solid form, it can be handled. And the skin will actually serve as a barrier to
radiation. But it's when it is in a particularized or finally divided form that
it's pyrophoric - it spontaneously bursts into flame on contact with air. And
under those circumstances, the tiniest particle if inhaled or ingested or taken
in through a cut in the skin could very likely lead to a cancer and to other
kinds of diseases.
And in fact the Department of Energy studies on
beagle dogs at the University of California, Davis, resulted in a bunch of dead
dogs. They couldn't find a particle placed in the lung that was so small that
it didn't cause a lung cancer. Every one of their experimental animals died
which is another small tragedy in the world of nuclear tragedies.
What are the alternatives, and specifically, what
are the alternatives to plutonium storage, if you will, or disposition? And
that's one question. And the other question is, what are the alternatives to
this nuclear energy path that we continue to be on despite all of the
accidents, dangers, expenses and so on?
MO: Well, there's good news, Jackie. And we need
it. But the fact is that all of this is a relic of not only the last century
but the last millennium but I believe the last age. Because we have survived
the nuclear age and if we don't do something quick, we may not. And so I think
the fact of the matter is, people in every country on every continent are
united in the perception that the world would be a far safer place if we had no
nuclear weapons at all, and if we did not use nuclear energy at all.
So I think as much as right now, there is so sort
of this fervor and this fear going around about security and terrorism,
underneath that is a bedrock that was identified in the 1990's and the 1980's
in various opinion polls and questionnaires and research projects, that
something like 7 out of 10 people in this country believe that getting rid of
nuclear weapons entirely would make the world safer.
And the reason I repeat that, even now, is the
fact that we can look around - in the grocery store, in our places of work, in
our schools - and know that if we believe in nuclear disarmament, and we
believe in a nuclear-free world, the majority of those around us agree with us.
Even if they're of a different political party, even if they're a different
gender, even if they're a different age. The majority of people actually
already agree with us.
And so how do we manifest that? How do we bring
it forward? How do we do it? And the even better news is that every time the
corporations try to do something like this mixed oxide fuel, or new weapons
production or whatever, it turns back around to the fundamental truth that this
stuff is not good for us. And more people wake up and more people realize we
have a problem.
And so every time the nuclear industry thinks
that they're moving forward, it's actually those of us who are working for the
preservation of life and the healing of the planet who get to go forward
because they inevitably go backwards.
And so the alternative to plutonium? Well, stop
making it. And where is it made? In reactors. Every single reactor on the
planet that uses uranium fuel makes plutonium. So when arms control people talk
about plutonium production, I start laughing because they're just talking about
the separation of the plutonium. It isn't until we turn off all the reactors
that we stop actually making plutonium.
MG: Is it 20% that's provided by nuclear power,
is that the correct number?
MO: It is a correct number than 20% of our
electric power, not our total energy – in total energy much less is
nuclear. But electric power is 20%. However, the single largest consumer of
electricity in the United States is the production of uranium fuel. It consumes
1%, which is one 100rds of the total electrical consumption of the United
States. And so in fact, the net
contribution is only 19% because if you turn off the fuel production at the
same time as you turn off the reactors, you only lose 19%.
How can we turn off the reactors? Well, it's
really very simple. For every dollar we spend on efficiency, which is not the
same thing as going without. Efficiency is when you have the same product or
the same service but you can look at the bottle and say, "Aha, I made this
bottle with less energy than this other bottle". And they're both bottles,
and it doesn't matter what the source of the energy was. If you're making the
same product with less energy, that's more efficient. And efficiency has - in
the United States, the capacity to displace the entire nuclear generating
outfit and a good chunk of the coal-generating outfit, if we only came to the
level of efficiency that Germany and Japan have. Germany and Japan today get 4
to 5 times more product, more service, for every unit of energy than we do here
in the United States.
If we want to be patriotic, in my humble opinion,
we need to adopt energy efficiency as our number one commitment and our number
one goal. And every corporation that produces anything should be thinking about
how to do it with less power. Everybody who delivers a service should be
thinking about how to do it with less power.
And the flip side of all this is the ability to
rebuild our economy through investment in renewable energy. And if every roof
in this country was a photovoltaic electrical generating roof, we could power
an economy at least three times the size of the one we have now. Just by using
the roofs we have. Without sacrificing another square acre of land for solar
power. That's not touching wind. In the state of South Dakota alone, if the
wind potential was realized, we could power the entire country at the level we
are at now.
So we have tremendous resources. We have the
ability to rebuild our economy by investing in those resources. And through the
efficient use of power, we could phase out nuclear almost overnight.
JC: You given us a very useful prescription. And
you've also let us know that it's going to take long time but we're going to
win. I'm very encouraged - thanks!
