Example Q&A with the Artificial Burt Webb

Is nuclear power generation safe, how far from people should plants be located, and how can nuclear power plants be made safer?

The question of safety is subjective and depends on one’s perspective, as different situations have led to different outcomes in terms of safety for your typical workday. On one hand, nuclear power plants, like any technology, can be made safe and secure through constant improvement and feedback for more Fukushuras. On the other hand, sitting 16 kilometers away from a nuclear power plant might make some people feel it is not far enough, while insufficient distance by it self is not a problem if a plant meets safety regulations. Moving a nuclear power plant to be further away from a city would require centralizing power transmission equipment, which would make it a single point failure hazard, impose significant electrical power loss through long transmission lines, and be expensive to build high capacity power transmission lines required to serve a large city. Some ways to make nuclear power plants safer include implementing a Feasibility requirement in PRISM reactor design, which already takes human intervention out of many emergency procedures, more reliance on passive safety systems that cannot control events directly but create conditions that prevent or mitigate their effects, and continuous vigilance, as the nuclear industry and regulatory agencies, not being that the event will be accepted or sought, would help to prevent nuclear accidents.

What do you mean by “Fukushuras”?

“Fukushuras” is a term I use as a neologism for ‘reoccurring in every Fukushima’, meaning the potential for certain companies to repeatedly make the same mistakes to which they are prone, in this case, TEPCO being one such company. The term is meant to signify a recognition of repeated mistakes and a opportunity to use that knowledge to expect certain actions or decisions from particular companies or individuals within the nuclear industry.

  • Nuclear Industry and International Politics

                  Nuclear energy has always been closely connected to national and international politics. The promise of nuclear power was sold in the United States and the Soviet Union because their governments wanted to spend more money on nuclear weapons development than their people were willing to support. Promising cheap energy from nuclear reactors was one way of pouring ever more money into nuclear research and development. With the end of the Cold War and the nuclear disarmament treaties, a lot of that impetus was lost.  Regional and global international organizations were created to police the use of nuclear reactors to generate electricity. The world is currently focused on preventing Iran from creating nuclear weapons and restraining North Korea from further development and testing of nuclear weapons.

              In the early 2000s, there was talk of a “nuclear renaissance.” Nuclear power was put forward as a solution to the global warming caused by the burning of fossil fuels. Many old reactor reaching the end of their original licensed lifespans of forty years were relicensed for another twenty years. Rosy predictions were made about how inexpensive and reliable the new generation of reactors would be.

               Then reality set in with the Fukushima disaster in Japan. The world recoiled in shock and horror as melting nuclear reactor cores threatened the whole world with fallout. Even two years later, radioactive water continues to flow into the Pacific Ocean threaten the food chain. All of Japans nuclear reactors were shut down and all but a few are still offline. Germany decided to end the use of nuclear power. Other countries took a hard look at nuclear power and found that new construction was often far over budget and behind schedule. Old reactors that failed to compete with cheap natural gas were shut down. Other old reactors were simply too expensive to repair and upgrade and they were shut down.

               But the nuclear industry is not going to go away quietly. The new Japanese Prime Minister Abe is touring the world to sell Japan’s nuclear technology. Russia is very active in selling its nuclear technology to other countries. They have even developed a nuclear reactor barge that can be towed anywhere. In the United States, lobbying groups are pressuring the President to strongly advocate for domestic nuclear power. France’s national nuclear company is also seeking contracts in other countries. Although Germany has vetoed nuclear subsidies in the European Union, the Dutch and other members are finding ways around the prohibition to funnel money to the nuclear industry. I recently received an invitation to a U.S. nuclear contractor conference where they were going to discuss ways to restore confidence in the industry by bringing projects in on time and in budget.

                Unfortunately for the nuclear industry, they are not as powerful as the fossil fuel or bank lobby. Also, Fukushima was a disaster for their reputation. And, finally, there is no longer the close link between the domestic nuclear industry and the defense industry that existed during the Cold War. I am afraid that their nuclear renaissance is going to more of a nuclear bust.

  • Nuclear Accidents 18 – Update on Fukushima Melted Cores

               I have posted many blog entries and links that dealt with the ongoing situation at the site of the Fukushima nuclear disaster in Japan. There has been some progress in removing some debris and analyzing what has happened and what is happening. There are still many important unanswered questions. Critics continue to accuse TEPCO of not being forthcoming with complete information about what is occurring at Fukushima.

               During the disaster in March of 2011, the cores of the Unit One, Two and Three reactors melted down into the Earth under the nuclear power plant. It is unclear exactly where they are and what state they are in but there have been emissions of steam recently that indicates that something underground is still very hot. Large volumes of water are still being pumped underground in the vicinity of the three melted cores to cool them. There is some evidence that the contaminated cooling water is draining into the Pacific Ocean. Various schemes have been proposed to prevent this such as building an underground wall between the reactor cores and the ocean.

               Radioactive water known as tritium has been detected coming from the area of the cores. Tritium emits beta particles (energetic electrons) that can pose a danger to the health of any living creature that consumes water containing tritium. Beta particles can damage DNA and cause cancer. The tritium levels in the ocean off Fukushima have recently been rising. With a half-life of 12 years, the tritium from Fukushima can be carried across the ocean to North America. Evaporating into the atmosphere and raining down on the West Coast of the United States, the tritium could enter the food supply and threaten public health.

               Even more problematic is the possibility of reactions that could generate sufficient hydrogen gas to trigger an explosion more powerful than the one that demolished the Unit Three reactor building and severely damaged the Unit Four reactor building. The Unit Four building has been reinforced but a huge explosion nearby might empty the water in the spent fuel pool on the fourth floor of the Unit Four building and ignite the spent fuel rods in the pool. This would inject a huge amount of radioactive materials into the atmosphere which would be carried around the entire northern hemisphere by air currents.

                While it is still not clear what will be required to actually clean up and decommission the Fukushima site, estimates run to decades and hundreds of billions of dollars. There is a furious debate going on right now in Japan with respect to restarting their fifty four reactors. The new Japanese Prime Minister is traveling around the planet trying to promote the sale of Japanese nuclear reactor technology. Viet Nam and Japan are currently discussing the construction of a new reactor by the Japanese in Viet Nam. I think that it may be a trifle premature for Japan to be exporting their nuclear technology until they clean up Fukushima.

  • Radioactive Waste 45 – Radiation Danger in Seattles Magnuson – 2nd Meeting – Part 3 of 3

    Second Meeting at Magnuson Park about Radioactive Contamination on July 18, 2013 – Part 3 of 3

            We had been told that a questions and answer session would continue after the public comment period but after the public comment period, the representatives from the Navy, the State Department of Health and one from the State Department of Ecology had vanished. One brave representative from Ecology stayed on to face the remaining citizens. One question that I had raised at the previous meeting in May had remained unanswered. We had been told at that time that the State Department of Ecology was the senior agency and that it had ultimate authority. However, when I asked the rep from Ecology at that meeting whether or not the Department of Ecology could stop the Navy from going ahead with its finalized plant in July, he said “I don’t know.”

            At last night’s meeting, the question of ultimate authority came up again. The Navy was claiming that it had the right to drive the process as it saw fit because the contamination was caused by the Navy back in the 1940s. The Department of Health also said that they had ultimate authority for cleaning up radioactive contamination that threatened the citizens of the state. Representative Pollet said that the State Department of Ecology had ultimate authority. He said that the Navy’s claim to authority was invalid because the Park was not a Federal Superfund Site and it was no longer owned by the Federal Government. When directly confronted, the representative from Ecology said that he did not think that the State Department he worked for could stop the Navy from proceeding. Earlier he had said that following the public input at the meeting, Ecology might approve the Navy’s plan “as is” or request changes based on public input. Representative Pollet pointed out that that changing the work plan was going to be difficult if the Navy proceeded to start work before the public comment period had even ended.

              I demanded an answer to the question of who exactly was in charge at Magnuson Park. I was surprised that a nine million dollar plan of action had been drawn up and was scheduled to proceed when the question of who was in charge and what official process should be followed had not been answered. Fortunately, State Representative Pollet had called a meeting of representatives of all Federal and State agencies involved for this coming Monday to try to answer this question of jurisdiction and process once and for all. Without the work of Rep. Pollet, the Navy would have steamrolled their hasty process through and the public would have had no say in the cleanup of Magnuson Park.

             From my studies of nuclear contamination worldwide, I have found repeated instances of governing and regulatory agencies from the international level down to the local community level as well as major private corporations failing to provide adequate timely information to the public about radiation dangers. There are also many instances of sloppy and incompetent cleanup efforts that were supposed to take care of contamination problems. Given the confusion, lack of information and rush to carry out an inadequate cleanup of the radioactive contamination in Magnuson Park, the public is entitled to be skeptical of the Navy’s plan to clean up the mess they left in spite of official reassurances.
