Nuclear Reactors 124 – Spent Nuclear Fuel Pools and Massive Solar Flares
In 1859, a huge solar storm injected so much energy into the atmosphere of the Earth that it caused major damage to the early power grid and the telegraph system in the United States. Some telegraph operators were shocked by arching electricity in their equipment. Fires broke out and generating systems crashed. This was referred to as the Carrington Event. Since that time, we have built an amazing but vulnerable civilization based on electrical power.
Recently, a huge solar flare just missed the Earth. Had it happened a week before, it might have cause serious damage to our electrical infrastructure as well as the shell of satellites orbiting the earth. The sun has eleven year cycles of solar activity. There are larger fluctuations in solar output that play out over decades and centuries. Historical records suggest that Carrington Events happen about every five hundred years so we will have a new Carrington type event eventually.
If we have a Carrington Event now, it could fry the entire electrical grid including generators, transmission lines, motors, electronics, etc. Without electricity and electronics, our civilization will collapse. We need electricity for manufacture, transportation and storage of food. It is estimated that most supermarkets in most cities have about a week or two worth of food. Without restocking, the food will disappear in weeks. We need electricity to treat water and sewage so drinking water and sewage systems will fail. We do have emergency generators but they generally run on diesel fuel. Once their onsite fuel is consumed within days of the disaster, there will be no more fuel because electricity is needed to pump the fuel out of tanks. Industry needs electricity to function so there will be no way to rebuild our electrical infrastructure. With cascading failures of energy, food, water, industry, transportation, etc. it is likely that billions of people will die in the first year and the rest of the human race will become hunter gatherers living in the ruins.
We have a hundred operating nuclear power reactors in the United States. They all have spent fuel pools where old fuel rods are cooled with water for years as they become less radioactive. Most of the spent fuel pools in the United States are rapidly filling up. If there was a Carrington Event, the national grid that supplies the electricity for the pumps that circulate the cooling water in the spent fuel pools will be gone. Emergency diesel generator will kick in automatically. Within hours or days, the emergency supply of diesel fuel will fail. What little fuel remains in the cities will be used by emergency vehicles and the military fighting fires and civil disorder. The spent fuel pools will heat the remaining water and it will boil off. Radioactive steam will be released. Once exposed to the air, many of the spent fuel rods will spontaneously burst into flame. Hydrogen gas generated by the cladding on the fuel rods will explode, blowing up the buildings housing the spent fuel pools. Smoke, steam and radioactive particles will spew out across the landscape. The Chernobyl disaster in Ukraine in 1986 irradiated an area the size of Alabama. One hundred burning spent fuel pools would likely cover the whole United States with radioactive fallout.
So, in addition to the destruction of our civilization by a Carrington Event, there will be a cloud of radioactive particles falling on the survivors in the ruins and shortening their already wretched lives. Unlike other problems that can arise at particular nuclear power plants, this disaster will be universal. There is no way that we can prevent a Carrington Event which could happen at any time. And, given the guaranteed destruction of human civilization, the burning spent fuel pools will only be adding insult to injury for the few survivors. We may be able to harden our electrical grid and our electronics to the point where they could survive a Carrington Event if we have enough time but only time will tell.

Nuclear Weapons 74 – The Soviet Doomsday Device
Dr. Strangelove was a 1964 black comedy about the cold war conceived, co-written and directed by the brilliant director Stanley Kubrick. A U.S. Air Force general goes insane and dispatches his bombers to the Soviet Union. The U.S. managed to recall or shoot down all but one of the bombers which ultimately drops a bomb on the Soviet Union. The punch line of the film is that the Soviet Union had constructed a “doomsday” device that will trigger automatically if a nuclear bomb is dropped on the Soviet Union but the rest of the world did not know about it. The film ends with the destruction of the world. It turns out that the plot of the film was not as preposterous as some might think.
Prior to the 1980s, it was assumed by the Soviets that they would have at least thirty minutes warning if the U.S. attempted to launch a first strike against the Soviet Union. This would provide enough time for a retaliatory launch by the Soviets. However, with the increasing accuracy of U.S. submarine missiles during the 1980s, the Soviets had to reconsider their ability to launch a retaliatory strike before the U.S. missiles hit their targets and disabled the Soviet nuclear capacity. U.S. submarines could approach the coast of the Soviet Union and launch missiles that could strike their targets within three minutes. This meant that Soviet missiles could be destroyed in their silos before they could launch.
After the fall of the Soviet Union in 1991, Russian military sources admitted that the Soviet Union had developed a fail-safe method of insuring that the Soviet Union could survive a first strike nuclear attack and retaliate successfully. The system is called Perimeter (also known as Dead Hand). Perimeter would automatically launch all missiles, triggered by a combination of light, radioactivity and overpressure, even if every nuclear command center and all of their leaders were destroyed. This system is similar to the doomsday device in Dr. Strangelove. Apparently the system still exists and is fully operational.
The post-Soviet Russian military sources claimed that the system would only be activated in case of a major international crisis and would be not be left on all the time. One of the reasons given for the development and deployment of the Perimeter system was that it would tend to lessen the risk of an accidental launch by panicked officers in a time of international tension. The reasoning was that if military planners could be assured that no matter what happened, if the Soviet Union had been attacked, a successful retaliation could be carried out there would be less inclination to launch missiles in ambiguous circumstances.
Of course, the possibility exists that a nuclear detonation within the Soviet Union coupled with a sabotage of communication systems might result in Perimeter launching an all out nuclear attack on the United States. It would certainly be better for the world if global nuclear disarmament were carried out and the Perimeter system permanently disabled. As I have pointed out in past blog posts, if either the U.S. or Russia launched only ten percent of their nuclear arsenals, the resultant nuclear winter would end human civilization. No one “wins” a nuclear war.
