Solar storms could cause power disruptions


A rare solar flare erupted from the sun on December 28 and is headed toward Earth at millions of miles per hour. The storm could create problems with technology while putting on an atmospheric show for some.

Scientists are on watch for the G3 level geomagnetic storm which is expected to hit Earth Wednesday and last through New Year’s Eve.

“The G3 is level three on a scale of one to six of geomagnetic activity,” said Terry Onsager, a physicist with the NOAA Space Weather Prediction Center. “That’s a measure of how much the Earth’s magnetic field on the ground gets disturbed.”

The solar event is considered moderate but still powerful enough to create some disturbance with technology.

“[The solar event] can drive currents through the power grid system that causes various issues with power generation and transmission,” said, Onsager.

Power grids could also be impacted. Officials with NV Energy said crews are on standby should anything happen.

A solar event of this size even has the capability of compromising GPS signals that many people depend on for personal navigation. However, experts don’t expect that interference to get you too off-target.

In a rare display not visible from Las Vegas, this solar storm could put on a stunning show for at least part of the country, pushing the Northern Lights as far south as Oregon, Iowa, and Pennsylvania.

“Certainly a storm of this magnitude would cause spectacular Aurora borealis at the high latitudes but, of course, it has to be night,” said Onsager.

This would mark the third time Earth has seen a solar event of this size in 2015.

The Space Weather Prediction Center at NOAA expects the solar storm to hit within the next few hours but the “storm watch” has been extended all the way through New Year’s Eve.

400 Chernobyls: Solar Flares, EMP, and Nuclear Armageddon


There are nearly 450 nuclear reactors in the world, with hundreds more either under construction or in the planning stages. There are 104 of these reactors in the USA 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 melt-downs 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 that have already died or continue to suffer from horrific radiation-related health problems (“Chernobyl AIDS”, epidemic cancers, chronic fatigue, etc) 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 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, quite similar to the disasters at both Chernobyl and Fukushima, but multiplied over 100 times. When massive solar flares launch a huge mass of highly charged plasma (a coronal mass ejection, or CME) directly towards Earth, colliding with our planet’s outer atmosphere and magnetosphere, the result is a significant geomagnetic disturbance.

Since an extreme GMD of such a potentially disruptive magnitude that it would collapse the grid across most of the US last occurred in May of 1921, long before the advent of  modern electronics, widespread electric power grids, and nuclear power plants, we are for the most part blissfully unaware of this threat and totally unprepared for its consequences. The good news is that there are some relatively affordable protective equipment and processes which could be installed to protect critical components in the electric power grid and its nuclear reactors, thereby protecting our civilization from this “end-of-the-world-as-we-know-it” scenario. The bad news is that, as of now, even though panels of scientists and engineers have studied the problem, and the bi-partisan congressional EMP commission has presented a list of specific recommendations to congress, our leaders have yet to approve and implement a single significant preventative measure!

Most of us believe something like this could never happen, and if it could, certainly our “authorities” would do everything in their power to make sure they would prevent such an Apocalypse from ever taking place. Unfortunately, the opposite is true. “How could this happen?” you might ask. “Is this truly possible?” Read and weep, for you will soon know the answer.

Nuclear Power Plants and the Electric Power Grid

Our global system of electrical power generation and distribution (“the grid”), upon which every facet of our modern life is utterly dependent, in its current form is extremely vulnerable to severe geomagnetic storms of a magnitude that tends 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 and gas pumping, and to conduct 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 spent fuel rod storage pond fires.

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 night-time 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 inexorably drifts towards the next naturally recurring, 100%  inevitable, super solar storm and resultant extreme GMD. The result of which in short order will end the industrialized world as we know it, incurring 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 one hundred 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 while also damaging similar transformers in New Jersey and the United Kingdom. More recently, in 2003 a solar storm of lesser intensity, but longer duration, caused a blackout in Sweden and induced powerful currents in the South African grid that severely damaged or destroyed fourteen of their major power transformers, impairing commerce and comfort over major portions of that country as they were 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[5]. 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% stronger than the Great Geomagnetic Storm of 1921[6]. 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[7].

Prior to the advent of the microchip and modern extra-high-voltage (EHV) transformers (key grid components that were first introduced in the late 1960’s), most electrical systems were relatively  robust and resistant to the effects of GMDs. Given the fact that a simple electrostatic spark can fry a microchip, and many thousands of miles of power lines act like giant antennas for capturing massive amounts of GMD spawned electromagnetic energy, the electrical systems of the modern world are far more vulnerable than their predecessors.

A growing number of scientists and engineers have become concerned about the vulnerability of both the grid and modern microelectronics to debilitating damage from severe electromagnetic disturbances. These could come either in the form of naturally occurring extreme GMDs, like what occurred during the 1921 and 1859 super solar storms, or an electromagnetic pulse (EMP) resulting from the deliberate detonation of a nuclear device at a high altitude above the earth.

The federal government recently sponsored a detailed scientific study to more fully understand the extent to which critical components of our national electrical power grid might be effected 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 Oakridge National Laboratory and the National Academy of Sciences,  Metatech corporation undertook extensive modeling and analysis of the potential effects of extreme geomagnetic storms upon the U.S. electrical power grid. They based their modeling upon a storm of intensity equal to the Great Geomagnetic Storm of 1921. Metatech estimated that within the continental United States alone, these voltage and current spikes combined with harmonic anomalies would severely damage or destroy over 350 EHV power transformers critical to the functioning of the U.S. grid, and possibly well over 2000 EHV transformers worldwide.[8]

EHV transformers are custom designed for each installation and are made to order, weighing as much as 300 tons each, and costing well over US 1$ million each. Given the fact that there is currently a three year waiting list for a single EHV transformer (due to recent demand from China and India, the lead times have grown 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 dire implications of this situation.

Growth of the US High Voltage Transmission Network and the Annual Electric Energy Usage over the Past 50 Years. In addition to increasing total network size, the network has grown in complexity with the introduction of higher-kilovolt rated lines that subsequently also tend to carry larger GIC (geomagnetically induced current) flows. (Grid size derived from data in the EHV Transmission Line Reference Book and the NERC Electricity Supply and Demand database; energy usage statistics from the US Department of Energy – Energy Information Administration.) [9]

The loss of thousands of EHV transformers worldwide would cause a catastrophic collapse of the grid, stretching 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.

Since the earth’s magnetic field tends to protect the tropical latitudes from the most damaging geomagnetic effects, with protection dropping as one travels closer to the poles, perhaps the infrastructure and manufacturing zones in places like Mexico, Malaysia, India, and Singapore will be spared. However, most of those countries probably also rely on goods and services imported from other parts of the world that would be crippled for many months (or years) in the event of  a an extreme GMD.

Severe geomagnetic storm with a 45 degree geomagnetic disturbance scenario. The above regions outlined are susceptible to system collapse due to the effects of extreme GMD disturbance. [10]

According to the various Metatech analyses, it is estimated that grid collapse will effect at least 130 million people in the United States alone. However, in a recent personal conversation, John Kappenman (author of the Metatech study) admitted that this estimate is probably grossly optimistic.[11] He noted that “killer trees” and other seemingly insignificant events have been attributed to being the tiny seeds that sprouted into giant multi-state blackouts. The massive Western States Blackout of August 10, 1996, apparently started when sagging power lines shorted against improperly pruned trees in Oregon during a triple-digit heat wave, cascading into a blackout that cut power to seven western states, parts of Baja, Mexico, and two Canadian provinces. Due to excessive loads from millions of air-conditioning units operating during the heat wave, the grid had been operating near peak capacity and the shorted lines threw it over the edge into cascading failure, affecting millions of customers[12].

A similar group of “killer trees” in the state of Ohio were apparently the root cause of the Great Northeastern Blackout of August 2003 that cut power to over 50 million people [13]. Kappenman also cited the recent September 2011 event where a utility technician flipped a switch to bypass a large series capacitor that was not working properly at a substation outside of Yuma Arizona, and for reasons not fully understood this caused a chain of events leading to  a massive cascading blackout that cut power to millions of customers in Arizona, California, and Mexico. This same blackout also caused two nuclear reactors at the San Onofre nuclear power plant to automatically shut down and go off line, which they are designed to do as a safety precaution in the event of a local grid failure. This exacerbated the situation by reducing the locally available generating capacity at the same time as utility workers were desperately trying to restore power to San Diego and other areas[14].

 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.

So 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, and 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 melt-down 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 the spent fuel storage pond of reactor number 4.

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 10 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 spanning hundreds of years. 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[16].

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 Arnie Gundersen, former Senior Vice President for Nuclear Engineering Services Corporation, now turned nuclear whistle-blower, once a zirconium fire has started, due to its extreme temperatures and high degree of 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, since this action will only make matters worse and lead to 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[16].

A few days after the tidal waves destroyed the generators providing back-up electrical power to Fukushima Daiichi’s cooling system, the protective water bath boiled away from the spent fuel pond for reactor no. 4, leaving the stored spent fuel rods partially exposed to the air. Had it not been for heroic efforts on the part of Japan’s nuclear workers to replenish water in this spent fuel pool, these spent rods would have melted down and their zirconium cladding would have ignited, which most likely would have released far more radioactive contamination than what came from the three reactor core meltdowns.

Japanese officials estimate that, to date, the Fukushima Daiichi nuclear disaster has released just over half of the total radioactive contamination released from Chernobyl, but other sources suggest that the radiation released could be significantly more. 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 boil off their water and become radioactive zirconium-fed infernos, the ensuing contamination will far exceed the cumulative effect of 400 Chernobyls.

Most of us tend to believe that a nuclear reactor is something that can be shut down in short order, like some massive piece of  machinery that can be turned off  by simply flipping a switch, or by performing a series of operations in a prescribed manner over a relatively short time, such as a few hours or perhaps a day or two. In spite of my MIT education (BSME, MIT, 1978), until recently I too was under the spell of this comforting delusion, which is far from the truth. You see, the trillions of chain reactions going on inside a nuclear reactor’s core continuously produce such incredible amounts of energy that a single nuclear power plant can generate more electricity than is required to power a good sized city. Unfortunately, these reactions do not simply “cease fire” at the flip of a switch. In general, it takes 5 to 7 days to slow down a reactor core’s nuclear chain reactions to the point where the core may be removed from the reactor.

After removal, the fuel rods are quite “hot”, both from the perspective of temperature and radioactivity. For the next 3 to 5 years these fuel rods must be immersed under roughly 20 feet of  continuously cooled water, both to shield the surrounding area from radioactivity, as well as to prevent catastrophic melt-down from occurring. According to Gundersen, after slowing down the chain reactions inside the reactor cores at Fukushima for a full eight months, the fuel rods would start melting down again if coolant flow was suspended for just 38 hours.

Gundersen explained that, essentially all modern nuclear reactors are designed with banks of “fuel rods”, which contain highly radioactive materials, combined with banks of “control rods”, which mesh between the fuel rods like the interwoven fingers of your right and left hands. It is the degree of interweave that moderates and controls the rate of nuclear chain reactions. He further explained that in the event of a significant loss of reactor control, reactors are designed for a “fail-safe” process to occur, where the control rods automatically fall into the fully meshed position with respect to the fuel rods, resulting in maximal slowing of the core’s nuclear reactions and beginning the process of shutting down the reactor.

Typically, this action rapidly reduces the power produced by these chain reactions by a factor of 20:1 (to 5.0 per cent of full power), but that still leaves thousands of horsepower worth of waste heat that must be removed if the reactor core is not to rapidly overheat and fail catastrophically. After a day of leaving the control rods in the fully interwoven position, this reaction slows to 1.0 per cent, and after a week it will be about 0.1 per cent of full power. Once the reactions in the fuel rods slow to the point where the rods may be removed from the reactor, the spent fuel rods must be cooled inside containment ponds for 3–5 more years before the nuclear reactions decay to a point where the rods can be moved to specially designed air-cooled storage banks.

As mentioned previously, nuclear power plants are only required to store enough backup fuel reserves on-site to keep their backup diesel generators running for a period of one week. The NRC has always operated from the assumption that extended grid “blackouts” would not last for periods of more than a few days. The government has promised that, in the event of a major catastrophe such as a Hurricane Katrina, diesel trucks will show up like clockwork at all troubled nuclear facilities until local grid-supplied electrical power services have been re-established. Unfortunately, governments and regulators have not considered the possibility that the next extreme GMD  which Mother Nature unleashes upon Earth will quite likely disrupt grid services over much of the industrial world for a period of years, not just days. The chances that the world’s nuclear reactors will receive weekly deliveries of diesel fuel under such chaotic circumstances are practically zero. In a world suffering from loss of fuel and electric power, if any such deliveries were attempted those fuel tankers would be prime targets for armed hijackers.

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 melt-downs. Japanese officials have estimate that the Fukushima Daiichi nuclear disaster has already released into the local environment just over half the total radioactive contamination as was released by Chernobyl, but other sources estimate it could be significantly more than was released by the accident at Chernobyl. In the event that 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 Asses the Threat to the United States from Electromagnetic Pulse (EMP) Attack[18]

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 many 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. 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 cause serious damage to electronics and electrical power grids along their line of sight, covering huge distances on the order of a circular area 1,500 miles (2,500 kilometers) in diameter, which would correspond to an area stretching roughly from Quebec City in Canada down to Dallas, Texas and reaching almost as far south as Miami, Florida. The geomagnetic effects of extreme solar storms are sometimes also described as a “natural EMP”.


Illustrative EMP effects—Fast Pulse E1 Effects. [19]

The concern is that some rogue state or terrorist organization might build their own nuclear device from scratch or buy one illegally, procure a Scud missile (or similar) on the black market and launch their nuclear device from a large fishing boat or freighter somewhere off the coast of the US, causing grid collapse and widespread damage to electronic devices across roughly 50% of America. Much like an extreme GMD, a powerful EMP attack would also cause widespread grid collapse, but it would be 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, which is followed by a longer duration disturbance known as an “E3” effect. The “E1” effect lasts on the order of a few nanoseconds, and is quite similar to massive electrostatic discharges, much like the sparks that surge from an extended fingertip after rubbing your feet on the carpet on a cold clear winter’s day, except they would surge through the hearts of electronic equipment distributed over a vast geographic area. These types of electrostatic spark discharges are particularly damaging to digital microelectronic chips  that are at the core of most modern electronic equipment.

The intermediate “E2” effects last a fraction of a second, and are similar to many thousands to millions of lightning strikes hitting over a widespread area at almost exactly the same time. Unfortunately, many of the devices designed to protect equipment from lightning damage, such as surge protectors, will be incapacitated by damage from the E1 pulse, leaving millions of electronic devices and systems susceptible to damage from the E2 effects.

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. The main difference between the E3 from an EMP and what occurs during an extreme GMD is that the EMP effect may continue for  a number of minutes, whereas the extreme GMD may continue for a number of hours or days. However, the magnitude of the induced magnetic field strengths from an EMP attack and an extreme GMD are about the same, with similar potential for causing severe damage to EHV transformers across the affected areas.

Inside the affected area, an EMP’s E3 effect would cause a similar degree of damage to the EHV transformers as that from an extreme GMD, but the E1 and E2 effects would cause far greater damage to electronic control systems than that from a GMD of similar intensity. Contrary to popular opinion, most personal electronic devices would probably survive with little or no damage, especially if they were not turned on at the moment of EMP, as would most automobiles. However, most complex electronic systems that contained digital microchips in combination with long runs of Ethernet cables (or other interconnecting cabling) which act like antennas for receiving EMP induced voltage spikes, would experience nearly 100% failure! [20]

A “successful” EMP attack launched against the US would most likely result in the immediate collapse of the grid across roughly 50% of the country, and crash the stock market. For the reasons discussed above, modern digital electronic control systems are highly susceptible to damage from EMP. These systems include programmable logic controllers (PLC), digital control systems (DCS),  and supervisory control and data acquisition systems (SCADA), all of which are absolutely critical for running factories, refineries, power plants, nuclear reactors, sewage plants, etc., as well as for diagnosing problems within those facilities and systems.

Bill Kaewert, President and CTO of Stored Energy Systems, LLC, a supplier of  backup power systems and components for mission-critical structures, such as Minuteman III missile silos, data centers, and critical corporate facilities, recently took part in a “Tabletop EMP” exercise hosted at the National Defense University. Dozens of the nation’s leading first responders, public safety experts, and military personnel took part in this exercise simulating a massive grid-down scenario typical of an EMP attack or an extreme GMD. According to Kaewert, even these highly trained personnel had a hard time grappling with the public safety implications of a disaster the size of fifty Hurricane Katrinas. It was also quite apparent that in an extended grid collapse a large number of emergency responders, military and government personnel would abandon their posts to protect their family and friends from the ensuing chaos[21].

In October of 1962, the Soviet Union conducted three above ground nuclear tests over Kazahhstan to study the effects of EMP. Due to its more northerly location, the EMP effects at the Kazahhstan test site were several times stronger than those observed during the more well known “Starfish Prime” nuclear test, where the U.S. military detonated a 1.4 megaton nuclear device in July of 1962, 250 miles above Johnston Island, which is 900 miles south of Honolulu, HI. During the Soviet EMP tests, massive current spikes were induced in a 600 mile (1000 kilometer) long high-voltage power line that was buried six feet (two meters) underground. Massive induced currents caused a fire in the Karaganda power plant at the far end of the line, burning it to the ground. In anticipation of power outages caused by the EMP tests, the Russian military had preplaced a backup diesel generators on site, but many of these generators were damaged by the EMP blast and would not start prior to being repaired. Located at great distances from the test site ground zero, several military radar units were also disabled by the EMP. Due to the use of solid-state devices containing microchips, today’s electrical devices are generally far less resistant to EMP damage than the devices in use during these EMP tests that took place back in the early 1960’s. In today’s world, scientists predict that within the heavily affected area an EMP strike would cripple many backup power systems along with the vast majority of digital electronic control systems.

Since his deployment with the U.S. military in the early 1980’s, Dr. George Baker has been involved the study of  EMP effects, as well as the design of EMP hardened devices, EMP weapons, and developing EMP standards for military and civilian usage. His resume reads like a “Who’s Who” of EMP, including being a Principal Staff member of the Congressional Commission to Asses the Threat to the United States from Electromagnetic Pulse (EMP). Baker states that, “electronic systems are so complex, from an electromagnetic coupling standpoint, that we simply cannot predict what will fail or survive an EMP event. Actual EMP testing is the only way to know whether or not a particular electronic device will survive an EMP attack.” [22]

The only good news about 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 US, as well as the rest of the outside world, left intact and able to lend a hand towards 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 crippling effect of an EMP attack from a single medium sized sub-orbital nuclear detonation!

The simple fact of the matter is that approximately 1/3 of the population of the U.S. lives within 50 miles of a nuclear power plant, the vast majority of which are located in the eastern half of the country—the prime target for an EMP attack. If the reactor vessel was breeched at the Indian Point nuclear power plant 38 mile north of New York City, and the city itself was contaminated with four times the safe level of Cesium 137 (a radioactive isotope that was deposited at dangerous levels on areas surrounding Fukushima), which has a half life of 30 years, then it would take roughly 60 years before the local Cesium 137 decayed to levels at which New York City could be safely re-occupied[23]. Given the likelihood that backup power systems will fail at a significant percentage of the nuclear installations within the EMP affected area, and the distinct probability that all utilities and central services would collapse over many of the nation’s population centers, the need to invest in preventative measures should be quite obvious.

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 insure the survival of the grid and other critical infrastructures in either event. John Kappenman, author of the Metatech study, estimates that it would cost on the order of $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[24].

To me, this is a no-brainer. For the cost of a single B-2 bomber or a tiny fraction of the TARP bank bailout, we could invest in preventative measures to avert what might well become the end of our civilization and life as we know it! There is no way to protect against all possible effects from an extreme GMD or an EMP attack, but certainly 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[25].

For more than 50 years, the US Army Corps of Engineers knew that New Orleans was a disaster waiting to happen, and they made plans for rebuilding the aging system of inadequate levies, but those plans were never implemented. Have we learned nothing from the wholly preventable flooding of New Orleans? Will we continue to ignore facts and pretend that “everything will be OK” while our world drifts towards the next inevitable extreme GMD, or until some terrorist organization or rogue state launches an EMP attack? This time, failure to prepare will not just mean the loss of a major city, but the end of the industrialized world as we know it, along with incalculable suffering, death, and environmental destruction.

We have a long ways to go to make our world EMP and GMD safe. Every citizen can do their part to push for legislation to move towards this goal, and to 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!
