There are nearly 450 nuclear reactors in the world, with hundreds more being planned or under construction. There are 104 of these reactors in the United States and 195 in Europe. Imagine what havoc it would wreak on our civilization and the planet’s ecosystems if we were to suddenly witness not just one or two nuclear meltdowns, but 400 or more! How likely is it that our world might experience an event that could ultimately cause hundreds of reactors to fail and melt down at approximately the same time? I venture to say that, unless we take significant protective measures, this apocalyptic scenario is not only possible, but probable.
Consider the ongoing problems caused by three reactor core meltdowns, explosions and breached containment vessels at Japan’s Fukushima Daiichi facility and the subsequent health and environmental issues. Consider the millions of innocent victims who have already died or continue to suffer from horrific radiation-related health problems (“Chernobyl AIDS,” epidemic cancers, chronic fatigue, etcetera) resulting from the Chernobyl reactor explosions, fires and fallout. If just two serious nuclear disasters, spaced 25 years apart, could cause such horrendous environmental catastrophes, it is hard to imagine how we could ever hope to recover from hundreds of similar nuclear incidents occurring simultaneously across the planet. Since more than one-third of all Americans live within 50 miles of a nuclear power plant, this is a serious issue that should be given top priority.[1]
In the past 152 years, Earth has been struck by roughly 100 solar storms, causing significant geomagnetic disturbances (GMD), two of which were powerful enough to rank as “extreme GMDs.” If an extreme GMD of such magnitude were to occur today, in all likelihood, it would initiate a chain of events leading to catastrophic failures at the vast majority of our world’s nuclear reactors, similar to but over 100 times worse than, the disasters at both Chernobyl and Fukushima. When massive solar flares launch a huge mass of highly charged plasma (a coronal mass ejection, or CME) directly toward Earth, colliding with our planet’s outer atmosphere and magnetosphere, the result is a significant geomagnetic disturbance.
The last extreme GMD of a magnitude that could collapse much of the US grid was in May of 1921, long before the advent of modern electronics, widespread electric power grids, and nuclear power plants. We are, mostly, blissfully unaware of this threat and unprepared for its consequences. The good news is that relatively affordable equipment and processes could be installed to protect critical components in the electric power grid and its nuclear reactors, thereby averting this “end-of-the-world-as-we-know-it” scenario. The bad news is that even though panels of scientists and engineers have studied the problem, and the bipartisan Congressional electromagnetic pulse (EMP) commission has presented a list of specific recommendations to Congress, our leaders have yet to approve and implement any significant preventative measures.
Most of us believe that an emergency like this could never happen, and that, if it could, our “authorities” would do everything in their power to prevent such an apocalypse. Unfortunately, the opposite is true. “How could this happen?” you might ask.
Nuclear Power Plants and the Electric Power Grid
Our current global system of electrical power generation and distribution (“the grid”), upon which our modern lifestyles are utterly dependent, is extremely vulnerable to severe geomagnetic storms, which tend to strike our planet on an average of approximately once every 70 to 100 years. We depend on this grid to maintain food production and distribution, telecommunications, Internet services, medical services, military defense, transportation, government, water treatment, sewage and garbage removal, refrigeration, oil refining, gas pumping and all forms of commerce.
Unfortunately, the world’s nuclear power plants, as they are currently designed, are critically dependent upon maintaining connection to a functioning electrical grid, for all but relatively short periods of electrical blackouts, in order to keep their reactor cores continuously cooled so as to avoid catastrophic reactor core meltdowns and fires in storage ponds for spent fuel rods.
If an extreme GMD were to cause widespread grid collapse (which it most certainly will), in as little as one or two hours after each nuclear reactor facility’s backup generators either fail to start, or run out of fuel, the reactor cores will start to melt down. After a few days without electricity to run the cooling system pumps, the water bath covering the spent fuel rods stored in “spent-fuel ponds” will boil away, allowing the stored fuel rods to melt down and burn [2]. Since the Nuclear Regulatory Commission (NRC) currently mandates that only one week’s supply of backup generator fuel needs to be stored at each reactor site, it is likely that, after we witness the spectacular nighttime celestial light show from the next extreme GMD, we will have about one week in which to prepare ourselves for Armageddon.
To do nothing is to behave like ostriches with our heads in the sand, blindly believing that “everything will be okay” as our world drifts towards the next natural, inevitable super solar storm and resultant extreme GMD. Such a storm would end the industrialized world as we know it, creating almost incalculable suffering, death and environmental destruction on a scale not seen since the extinction of the dinosaurs some 65 million years ago.
The End of “The Grid” as We Know It
There are records from the 1850s to today of roughly 100 significant geomagnetic solar storms, two of which, in the last 25 years, were strong enough to cause millions of dollars worth of damage to key components that keep our modern grid powered. In March of 1989, a severe solar storm induced powerful electric currents in grid wiring that fried a main power transformer in the HydroQuebec system, causing a cascading grid failure that knocked out power to 6 million customers for nine hours and damaging similar transformers in New Jersey and the UK. More recently, in 2003, a less intense but longer solar storm caused a blackout in Sweden and induced powerful currents in the South African grid that severely damaged or destroyed 14 of their major power transformers, impairing commerce and comfort over major portions of that country as it was forced to resort to massive rolling blackouts that dragged on for many months.[3]
During the great geomagnetic storm of May 14-15, 1921, brilliant aurora displays were reported in the Northern Hemisphere as far south as Mexico and Puerto Rico, and in the Southern Hemisphere as far north as Samoa.[4] This extreme GMD produced ground currents roughly ten times as strong as the 1989 Quebec incident. Just 62 years earlier, the great granddaddy of recorded GMDs, referred to as “the Carrington Event,” raged from August 28 to September 4, 1859. This extreme GMD induced currents so powerful that telegraph lines, towers and stations caught on fire at a number of locations around the world. Best estimates are that the Carrington Event was approximately 50 percent stronger than the 1921 storm.[5]Since we are headed into an active solar period much like the one preceding the Carrington Event, scientists are concerned that conditions could be ripe for the next extreme GMD.[6]
Prior to the advent of the microchip and modern extra-high-voltage (EHV) transformers (key grid components that were first introduced in the late 1960s), most electrical systems were relatively robust and resistant to the effects of GMDs. Given that a simple electrostatic spark can fry a microchip and thousands of miles of power lines could act like giant antennas for capturing massive amounts of GMD-spawned electromagnetic energy, modern electrical systems are far more vulnerable than their predecessors.
The federal government recently sponsored a detailed scientific study to better understand how much critical components of our national electrical power grid might be affected by either a naturally occurring GMD or a man-made EMP. Under the auspices of the EMP Commission and the Federal Emergency Management Agency (FEMA), and reviewed in depth by the Oak Ridge National Laboratory and the National Academy of Sciences, Metatech Corporation undertook extensive modeling and analysis of the potential effects of extreme geomagnetic storms on the US electrical power grid. Based upon a storm as intense as the 1921 storm, Metatech estimated that within the United States, induced voltage and current spikes, combined with harmonic anomalies, would severely damage or destroy over 350 EHV power transformers critical to the functioning of the US grid and possibly impact well over 2000 EHV transformers worldwide.[7]
EHV transformers are made to order and custom-designed for each installation, each weighing as much as 300 tons and costing well over $1 million. Given that there is currently a three-year waiting list for a single EHV transformer (due to recent demand from China and India, lead times grew from one to three years), and that the total global manufacturing capacity is roughly 100 EHV transformers per year when the world’s manufacturing centers are functioning properly, you can begin to grasp the implications of widespread transformer losses.
The loss of thousands of EHV transformers worldwide would cause a catastrophic grid collapse across much of the industrialized world. It will take years, at best, for the industrialized world to put itself back together after such an event, especially considering the fact that most of the manufacturing centers that make this equipment will also be grappling with widespread grid failure.
Our Nuclear “Achilles Heel”
Five years ago, I visited the still highly contaminated areas of Ukraine and the Belarus border where much of the radioactive plume from Chernobyl descended on 26 April 1986. I challenge chief scientist John Beddington and environmentalists like George Monbiot or any of the pundits now downplaying the risks of radiation to talk to the doctors, the scientists, the mothers, children and villagers who have been left with the consequences of a major nuclear accident. It was grim. We went from hospital to hospital and from one contaminated village to another. We found deformed and genetically mutated babies in the wards; pitifully sick children in the homes; adolescents with stunted growth and dwarf torsos; fetuses without thighs or fingers and villagers who told us every member of their family was sick. This was 20 years after the accident, but we heard of many unusual clusters of people with rare bone cancers…. Villages testified that ‘the Chernobyl necklace’ – thyroid cancer – was so common as to be unremarkable.

What do extended grid blackouts have to do with potential nuclear catastrophes? Nuclear power plants are designed to disconnect automatically from the grid in the event of a local power failure or major grid anomaly; once disconnected, they begin the process of shutting down the reactor’s core. In the event of the loss of coolant flow to an active nuclear reactor’s core, the reactor will start to melt down and fail catastrophically within a matter of a few hours, at most. In an extreme GMD, nearly every reactor in the world could be affected.
It was a short-term cooling-system failure that caused the partial reactor core meltdown in March 1979 at Three Mile Island, Pennsylvania. Similarly, according to Japanese authorities, it was not direct damage from Japan’s 9.0 magnitude Tohoku Earthquake on March 11, 2011, that caused the Fukushima Daiichi nuclear reactor disaster, but the loss of electric power to the reactor’s cooling system pumps when the reactor’s backup batteries and diesel generators were wiped out by the ensuing tidal waves. In the hours and days after the tidal waves shuttered the cooling systems, the cores of reactors number 1, 2 and 3 were in full meltdown and released hydrogen gas, fueling explosions which breached several reactor containment vessels and blew the roof off the building housing reactor number 4′s spent-fuel storage pond. Of even greater danger and concern than the reactor cores themselves are the spent fuel rods stored in on-site cooling ponds. Lacking a permanent spent nuclear fuel storage facility, so-called “temporary” nuclear fuel containment ponds are features common to nearly all nuclear reactor facilities. They typically contain the accumulated spent fuel from ten or more decommissioned reactor cores. Due to lack of a permanent repository, most of these fuel containment ponds are greatly overloaded and tightly packed beyond original design. They are generally surrounded by common light industrial buildings with concrete walls and corrugated steel roofs. Unlike the active reactor cores, which are encased inside massive “containment vessels” with thick walls of concrete and steel, the buildings surrounding spent fuel rod storage ponds would do practically nothing to contain radioactive contaminants in the event of prolonged cooling system failures.
Since spent fuel ponds typically hold far greater quantities of highly radioactive material then the active nuclear reactors locked inside reinforced containment vessels, they clearly present far greater potential for the catastrophic spread of highly radioactive contaminants over huge swaths of land, polluting the environment for multiple generations. A study by the Nuclear Regulatory Commission (NRC) determined that the “boil down time” for spent fuel rod containment ponds runs from between 4 and 22 days after loss of cooling system power before degenerating into a Fukushima-like situation, depending upon the type of nuclear reactor and how recently its latest batch of fuel rods had been decommissioned.[9]
Reactor fuel rods have a protective zirconium cladding, which, if superheated while exposed to air, will burn with intense, self-generating heat, much like a magnesium fire, releasing highly radioactive aerosols and smoke. According to nuclear whistleblower and former senior vice president for Nuclear Engineering Services Arnie Gundersen, once a zirconium fire has started, due to its extreme temperatures and high reactivity, contact with water will result in the water dissociating into hydrogen and oxygen gases, which will almost certainly lead to violent explosions. Gundersen says that once a zirconium fuel rod fire has started, the worst thing you could do is to try to quench the fire with water streams, which would cause violent explosions. Gundersen believes the massive explosion that blew the roof off the spent fuel pond at Fukushima was caused by zirconium-induced hydrogen dissociation.[10]
Had it not been for heroic efforts on the part of Japan’s nuclear workers to replenish waters in the spent fuel pool at Fukushima, those spent fuel rods would have melted down and ignited their zirconium cladding, which most likely would have released far more radioactive contamination than what came from the three reactor core meltdowns. Japanese officials have estimated that Fukushima Daiichi has already released just over half as much total radioactive contamination as was released by Chernobyl into the local environment, but other sources estimate it could be significantly more than at Chernobyl. In the event of an extreme GMD-induced long-term grid collapse covering much of the globe, if just half of the world’s spent fuel ponds were to boil off their water and become radioactive, zirconium-fed infernos, the ensuing contamination could far exceed the cumulative effect of 400 Chernobyls.
Electromagnetic Pulse (EMP) Attack
Many of the control systems we considered achieved optimal connectivity through Ethernet cabling. EMP coupling of electrical transients to the cables proved to be an important vulnerability during threat illumination…. The testing and analysis indicate that the electronics could be expected to see roughly 100 to 700 ampere current transients on typical Ethernet cables. Effects noted in EMP testing occurred at the lower end of this scale. The bottom line observation at the end of the testing was that every system failed when exposed to the simulated EMP environment.
— Report of the Commission to Assess the Threat to the United States from Electromagnetic Pulse (EMP) Attack [11]
Electromagnetic pulses (EMPs) and solar super storms are two different, but related, categories of events that are often described as high-impact, low frequency (HILF) events. Events categorized as HILF don’t happen very often, but if and when they do, they have the potential to severely affect the lives of millions of people. Think of an EMP as a super-powerful radio wave capable of inducing damaging voltage spikes in electrical wires and electronic devices across vast geographical areas. (Note that the geomagnetic effects of solar storms are also described as “natural EMP.”)
What is generally referred to as an EMP strike is the deliberate detonation of a nuclear device at a high altitude, roughly defined as somewhere between 24 and 240 miles (40 and 400 kilometers) above the surface of the Earth. Nuclear detonations of this type have the potential to seriously damage electronics and electrical power grids along their line of sight, covering distances on the order of an area 1,500 miles (2,500 kilometers) in diameter, an area roughly equal to the distance between Quebec City in Canada and Dallas, Texas.
The concern is that some rogue state or terrorist organization might build its own nuclear device from scratch or buy one illegally, procure a Scud missile (or similar weapon) on the black market and launch the nuclear device from a large fishing boat or freighter somewhere off the coast of the United States, causing grid collapse and widespread damage to electronic devices across roughly 50 percent of America. Much like an extreme GMD, a powerful EMP attack would also cause widespread grid collapse, but one limited to a much smaller geographical area.
A powerful EMP from a sub-orbital nuclear detonation would cause extreme electromagnetic effects, starting with an initial, short-duration, “speed of light” pulse, referred to as an “E1″ effect, followed by a middle-duration pulse called an “E2″ effect, followed by a longer-duration disturbance known as an “E3″ effect. The “E1″ effect lasts a few nanoseconds and is similar to massive discharges of electrostatic sparks, which are particularly damaging to digital microelectronic chips used in most modern electronic equipment.
The “E2″ effects last a fraction of a second and are equal to many thousands to millions of lightning strikes hitting over a widespread area at almost exactly the same time. In the case of a nuclear-induced EMP, its E3 effect starts after about a half-second and may continue for several minutes. The E3 effect can be thought of as a “long, slow burn,” and, electromagnetically, it is quite similar to the effects from an extreme GMD, except that the latter may continue for a number of hours or days.
A “successful” EMP attack launched against the US would most likely result in the immediate collapse of the grid across roughly 50 percent of the country, a stock market crash and critical failures in many affected areas’ electronic systems that control nuclear reactors, chemical plants, telecommunications systems and industrial processes. These systems include programmable logic controllers (PLC), digital control systems (DCS), and supervisory control and data acquisition systems (SCADA).
The only good news about an EMP strike is that its effect will cover a much smaller area than an extreme GMD, so there will be a significant portion of the rest of the United States, as well as the rest of the outside world, left intact and able to lend a hand toward rebuilding critical infrastructure in the affected areas. Imagine the near-total loss of a functioning infrastructure across an area of about a million square miles (approximately 1.6 million square kilometers, roughly equivalent to 50 Hurricane Katrinas happening simultaneously) and you will have some idea of the potentially crippling effect of an EMP attack from a single, medium-sized, sub-orbital nuclear detonation!
Preventing Armageddon
The Congressionally mandated EMP Commission has studied the threat of both EMP and extreme GMD events and made recommendations to the US Congress to implement protective devices and procedures to ensure the survival of the grid and other critical infrastructures in either event. John Kappenman, author of the Metatech study, estimates that it would cost about $1 billion to build special protective devices into the US grid to protect its EHV transformers from EMP or extreme GMD damage and to build stores of critical replacement parts should some of these items be damaged or destroyed. Kappenman estimates that it would cost significantly less than $1 billion to store at least a year’s worth of diesel fuel for backup generators at each US nuclear facility and to store sets of critical spare parts, such as backup generators, inside EMP-hardened steel containers to be available for quick change-out in the event that any of these items were damaged by an EMP or GMD.[12]
For the cost of a single B-2 bomber or a tiny fraction of the Troubled Asset Relief Program (TARP) bank bailout, we could invest in preventative measures to avert what might well become the end of life as we know it. There is no way to protect against all possible effects from an extreme GMD or an EMP attack, but we could implement measures to protect against the worst effects. Since 2008, Congress has narrowly failed to pass legislation that would implement at least some of the EMP Commission’s recommendations.[13]
We have a long ways to go to make our world EMP and GMD safe. Citizens can do their part to push for legislation to move toward this goal and work inside our homes and communities to develop local resilience and self reliance, so that in the event of a long-term grid-down scenario, we might make the most of a bad situation. The same tools that are espoused by the Transition movement for developing local self-reliance and resilience to help cope with the twin effects of climate change and peak oil could also serve communities well in the event of an EMP attack or extreme GMD. If our country were to implement safeguards to protect our grid and nuclear power plants from EMP, it would also eliminate the primary incentive for a terrorist to launch an EMP attack. The sooner we take these actions, the less chance that an EMP attack will occur.
