Part One of Four Parts
In my last several posts, I have been covering ten problems with nuclear power and ten dangerous misconceptions about nuclear power and radiation. Today, I am going to cover my own list of nuclear problems that do not get as much attention as the items on the other two lists but do deserve to be discussed.
1) Insurance issues: Potential liability for nuclear accidents is a very big issue worldwide. In the United States, the nuclear industry would not be possible without the Price-Anderson Act which limits amount of money that the owners of nuclear power plants can be charged for nuclear accidents. It is likely that in the event of a major nuclear accident in the U.S., the cost of the accident will exceed the amount that the owners will have to pay with the rest being passed along to the taxpayers. There was a scandal in South African recently because a secret deal with Russia for a nuclear reactor contained a provision that Russian nuclear technology suppliers not be liable for damages caused by an accident involving their equipment. India is having problems with nuclear technology imports because they have very stringent liability laws for the manufacturers of equipment involved in industrial accidents. The potential cost of a major nuclear accident is difficult to estimate but it may cost far more than any insurance coverage will pay for.
2) Emissions from operating reactors during refueling: Up until recently, nuclear power plants in the U.S. were allowed to report radioactive steam and gases emissions levels in terms of the emissions averaged over a year. However, critics of the reporting system have pressured regulators to have nuclear power plants report the daily releases of radioactive steam and gases. It has been revealed that while the average annual releases are well within what are considered to be safe levels, whenever the containment vessel is opened for refueling, there is a serious spike in emissions that rises well above safe levels posing a threat to people who live down wind of the plant. This is a danger not related to an accident but present whenever a nuclear reactor is refueled during normal, supposedly safe, operation.
3) Deficiency of dry cask design: The cooling pools at nuclear reactors in the U.S. are rapidly filling up. If some of the spent fuel in the pools is not removed, all operating reactors will have to be shut down when it comes time to refuel because there will be no place to put the spent fuel. The current plan is for spent fuel to be placed in steel and concrete containers called “dry casks” either at the reactor site or at a temporary storage facility offsite. The problem with this plan is the fact that the current design for commercial dry casks does not include a way to monitor dangerous gas build up in the casks that might cause an explosion. The massive cask building program that will be necessary to take the existing spent fuel will increase the odds of the rupture of a cask and the release of nuclear contamination. New casks are being developed but they will have to be tested and licensed before being available commercially. This will probably take at least five years and the existing spent fuel will have to be moved before then to prevent nuclear plant shutdowns. In addition, a massive amount of concrete will have to be used for all the new dry casks which will release additional carbon dioxide into the atmosphere.
