It may not come as a surprise to some of you, but now it has been confirmed that in order to reduce the risk for global warming, we have to invest in more nuclear power. Whether we like it or not! This opinion may not be particularly interesting if it merely was my own, but when it for the first time in its history comes from the International Energy Agency, there are reasons to raise eyebrows even for the most green-blooded fanatics.
Although several countries, including India, China, the US and France, are already planning more nuclear plants, and others such as the UK are in the early stages of backing new reactors, many countries still oppose any addition to nuclear capacity, including Germany, Spain and Sweden, of course.
Now, IEA claim that: “We need a decision almost tomorrow if we are going to act before we reach a point of no return in climate and security of supply.” This means that politicians need to persuade reluctant voters that nuclear power is safe and necessary. In order to bolster energy security and combat global warming, i.e. to save the environment!
The agency find modern nuclear power to be cost competitive with coal and gas, its main rivals, and concludes that there is enough uranium deposits to meet renewed demand. The $17.000 billion energy investment needs until 2030 has risen significantly and the world is “on an energy path that is vulnerable, dirty and expensive.” The goal is therefore to “prepare an alternative path ... to a cleaner, safer, less costly system”, which requires nuclear power investments, but also greater energy efficiency, new technology developments in renewable energy, especially bio-fuels for transport and wind for power generation. But, a development without nuclear energy is no realistic alternative! Wind and solar power have their place, but because they are intermittent and unpredictable they simply can’t replace big base load plants such as coal, nuclear and hydroelectric. Natural gas, a fossil fuel, is too expensive already, and its price is too volatile to risk building big base-load plants.
Given that hydroelectric resources are built pretty much to capacity, nuclear is, by elimination, the only viable substitute for coal. It’s that simple.
Today, the United States have more than six hundred coal-fired plants that emit nearly 2 billion tons of CO2 annually, which is the equivalent of the exhaust from about 300 million automobiles. In addition, the Clean Air Council reports that these coal plants are responsible for 64 percent of sulfur dioxide emissions, 26 percent of nitrous oxides and 33 percent of mercury emissions. These pollutants are eroding the health of the environment, producing acid rain, smog, respiratory illness and mercury contamination.
Meanwhile, the 103 nuclear plants operating in the United States effectively avoid the release of 700 million tons of CO2-emissions annually, the equivalent of the exhaust from more than 100 million automobiles. Imagine if the ratio of coal to nuclear were reversed so that only 20 percent of the Americans electricity was generated from coal and 60 percent from nuclear. This would go a long way toward cleaning the air and reducing greenhouse gas emissions. Every responsible environmentalist should support a move in that direction, not the least for China, where the emission growth in the world is highest.
The core problem with nuclear energy is its associated myths that are extensively exploited by the green lobby activists. The first one has always been that nuclear energy is expensive, all cost taken into account, while the fact is exactly the reverse. In 2004, the average cost of producing nuclear energy in the United States was less than two cents per kilowatt-hour, comparable with coal and hydroelectric. Advances in technology will bring the cost down further in the future, while nobody can forecast the price of oil and gas anymore and the indirect environmental costs of CO2-emmissions are potentially mind-boggling.
The second issue concerns safety. Although Three Mile Island was a success story, the accident at Chernobyl was clearly not. This early model of Soviet reactor had no containment vessel, was an inherently bad design and its operators literally blew it up. The multi-agency U.N. Chernobyl Forum reported last year that 56 deaths could be directly attributed to the accident, most of those from radiation or burns suffered while fighting the fire. Tragic as those deaths were, they pale in comparison to the more than 5,000 coal-mining deaths that occur worldwide every year. The fact is that no one has died of a radiation-related accident in the history of civilian nuclear reactor programs in the Western world. Although hundreds of uranium mine workers did die from radiation exposure underground in the early years of that industry, this problem has now been corrected.
Nuclear waste is another big issue and the claim that it will be a societal danger for thousands of years. The fact is that within forty years, used fuel has less than one-thousandth of the radioactivity it had when it was removed from the reactor. And it is also incorrect to call it waste, because up to 95 percent of the potential energy is still contained in the used fuel after the first cycle. Now that the United States has removed the ban on recycling used fuel, it will be possible to use that energy and to greatly reduce the amount of waste that needs treatment and disposal. Several countries are now entering the nuclear-fuel-recycling business.
The recent major concern has perhaps been that nuclear reactors are vulnerable to terrorist attack. The fact is that the six-feet-thick reinforced concrete containment vessel protects the contents from the outside as well as the inside. Even if a jumbo-jet did crash into a reactor and in the unlikely event of breaching the containment, the reactor would not explode. In fact, the normal extraordinary safety measures of nuclear plants also increase safety from a terrorist attack. Instead, there are many other types of facilities that are far more vulnerable to terrorist attacks, including liquid natural gas plants, chemical plants and numerous other political targets.
Nuclear fuel can be diverted to make nuclear weapons. This is the most serious issue associated with nuclear energy and the most difficult to address, as the examples of North-Korea and Iran shows. But just because nuclear technology can be put to evil purposes is not an argument to ban its use. The only practical approach to the issue of nuclear weapons proliferation is to put it higher on the international agenda and to use diplomacy and, where necessary, force to prevent countries or terrorists from using nuclear materials for destructive ends. Rather, increased safety shall be a motivator for new inventions and solutions. And new technologies such as the reprocessing system recently introduced in Japan, in which the plutonium is never separated from the uranium, can make it much more difficult for terrorists or rogue states to use civilian materials to manufacture weapons.
In 1979, Jane Fonda and Jack Lemmon produced a frisson of fear with the blockbuster movie; “The China Syndrome,” a fictional evocation of nuclear disaster in which a reactor meltdown threatens a city’s survival. Less than two weeks after the opening, a reactor core meltdown at Pennsylvania's Three Mile Island nuclear power plant sent shivers of very real anguish throughout the world, not the least in my home country. Because of this
double entendre nobody noticed that the Three Mile Island was in fact a success story. The concrete containment structure did just what it was designed to do; to prevent radiation from escaping into the environment. Although the reactor itself was crippled, there was no injury or death among nuclear workers or nearby residents. Three Mile Island was the first and only serious accident in the history of nuclear energy generation in the United States, but under heavy fire from Hollywood, it was enough to scare away any further development of the technology and new plant investments. In Sweden, we even made it unlawful to improve nuclear technology.
Is it not outlandish and somewhat bizarre that, in retrospect, when the facts are known, it turns out that the pro-nuclear or rather least negative nuclear “Linje 1 – voters” in the public Swedish referendum, 1980, turns out to be the ones who were most environmentally friendly?
Perhaps, the green lobbyists and “Linje 3 – voters” were too much under influence of Fonda and Lemmon than doing the homework on technology and environmental facts?
