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 Reactors 164 – The NRC Certifies the New GE-HItachi Economical Boiling Water Reactor Design

              New nuclear reactor designs are constantly being developed. Any design that will be built in the United States has to get approval from the NRC. That approval is a critical step in the construction of any new reactor. The NRC has just approved the design of the GE-Hitachi Nuclear Energy’s Economic Simplified Boiling-water Reactor (ESBWR) for use in the U.S. Once the new certification rule is published in the U.S. Federal Register, thirty days later the rule goes into effect.

             The ESBWR is designed to generate about one and one half gigawatts of electricity. The design includes what is called natural circulating coolant. There are passive safety features involved which would be able to cool down the reactor automatically without human involvement in case of a malfunction or a serious accident. The design includes a taller reactor vessel, a shorter core and improved water flow through the vessel all of which serve to enhance natural circulation of water. It also includes an isolated condenser system that can control the level of the water and also dissipate heat from radioactive decay while the reactor vessel is pressurized. And, finally, if the reactor pressure falls, there is a gravity driven cooling system that will maintain water levels. GE-Hitachi first submitted the ESBWR design to the NRC in 2005.

             The NRC carried out a thorough engineering evaluation on the design and issued a safety evaluation report in early 2011. There was a draft certification rule notice that was published following the report. Included in the notice were public comments and petitions being circulated by activists. Following the draft certification notice, the NRC requested additional information about the steam dryer in the design. The steam dryer prevents excess moisture from causing damage to the turbine that generates the electricity in a nuclear power plant. In May of 2014, the NRC issued a supplement to the original draft certification notice to take into account changes in the analysis of the steam dryer in the design. There were no public comments about the supplemental material added to the original draft certification notice.

             The NRC is considering two combined construction and operating applications that include the new GE-Hitachi reactor design. Detroit Edison wants to add a third reactor to the Fermi plant in Monroe County, Michigan. Dominion Virginia Power is asking for a license to add a third reactor to the North Anna power plant in Louisa County, Virginia. It is expected that the NRC will issue a license for the new Fermi reactor in 2015 and a license for the new North Anna reactor in 2016.

            In addition to the certification of the new ESBWR design, the NRC has certified four other new reactor designs. These include the Advanced Boiling Water Reactor, the System 80+, the AP600 and the AP1000. The Chinese are developing their own reactor design based on the AP1000. There are several reactor construction projects around the globe which involve the AP1000 design.

  • Nuclear Reactors 163 – U.S. Taxpayer Will Pay Dearly for Our Use of Nuclear Power

             I have stated in previous blogs that when you consider all the different factors such as economic, political, social, technological, public health and environmental, it is obvious that nuclear energy is not a good way to produce electricity.  I have often said that the only reason nuclear power is still being discussed as a viable power source is because there is so much money involved in their construction and operation. The nuclear industry has been very successful at offloading liabilities and pocketing profits with the help of a bought and paid for Congress and an industry friendly Nuclear Regulatory Agency.

           In South Carolina, the state regulatory agency has allowed the company constructing two new nuclear reactors to pass the cost overruns along to the utility customers even though the unfinished plants have generated no electricity. Some states such as Florida have or had laws on the books that would allow nuclear power companies to charge their customers for the construction costs of nuclear power plants that were never completed and never generated electricity.

           If the company building new reactors in Georgia happens to go bankrupt, Congress has given them generous loan guarantees which means that the construction costs of the abandon reactor projects will be passed along to the U.S. taxpayers.

           If there should happen to be a major nuclear accident in the U.S. as serious as the March 11, 2013 disaster at Fukushima, the companies responsible are insulated from responsibility for the billions of dollars that the accident will ultimately cost. The Price-Anderson Act requires that each operating nuclear power plant purchase the maximum insurance that is available which is three hundred and seventy five million dollars. Beyond that, if an accident occurs at nuclear plant and the costs exceed the insurance, power plant owners  are obligated to pay one hundred and twenty one million dollars into a national fund that will be used to pay for additional costs of the accident. If the cost of an accident exceeds the four hundred and ninety million dollars from the insurance coverage and the extra money from the nuclear power operator, then the Congress can require additional money from the nuclear power operator. If the cost of an accident exceeds the ability of a company to pay, then the U.S. taxpayer will pay the additional cost.

           In 2013, four out of the one hundred and four U.S. power reactors were shut down for a variety of reasons including being too expensive to repair or being uncompetitive in the energy market. Activists are calling for the last nuclear power plant in California to be shut down. Most of the remaining nuclear power reactors in the U.S. are reaching the end of their licensed life spans. More will be shut down because they will be too expensive to repair or uncompetitive.

            Russia, China, France and Japan are moving aggressively to make nuclear technology exports a major component of their international trade. Russia and China are committed to building dozens of new reactors in the near future. Fortunately, for all the problems that the U.S. has with nuclear power, embarking on a major building and exporting program for nuclear reactors is not one of them. The electricity supplied by nuclear reactors in the U.S. can and should be replaced by renewables and conservation as soon as possible. In any case, I am sure that the U.S. taxpayer will still wind up paying dearly for our use of nuclear power.

  • Nuclear Weapons 92 – Los Almos National Laboratory Fires an Employee for Publication of an Article of Nuclear Disarmament

             James Doyle spent seventeen years as a nuclear policy specialist at the U.S. Los Alamos National Laboratory (LANL). The LANL receives about two billion dollars each year for work that includes nuclear weapons development. Last year Doyle published an article titled “Why Eliminate Nuclear Weapons?” in the journal Survival: Global Politics and Strategy. This journal is published by the International Institute for Strategic Studies in the U.K. Following the publication of this article, Doyle lost his job at LANL.

             Doyle’s article pointed out that nuclear weapons no longer provided strategic utility or value as a deterrent for war. He said that eliminating nuclear weapons would strongly increase international security. He also said that he thought that now was a good time to hold serious discussions about global nuclear disarmament. Although President Obama supports nuclear disarmament, he did not think that it would happen in his lifetime. Doyle suggested that it should be possible to achieve total nuclear armament in thirty four years which would mean that the world would have eliminated nuclear weapons before the one hundredth anniversary of the dropping of atomic bombs on Hiroshima and Nagasaki at the end of the Second World War. There are still advocate for nuclear weapons but many respected voices in the world of global security agree publicly with the ideas expressed in Doyle’s article.

             Doyle’s dismissal from LANL is detailed in a report by the Center for Public Integrity. Because Doyle wrote his article at home outside of working hours, he was not obligated to show the article to LANL for what is called a “classification” review. However, Doyle did submit the article to LANL for review. One of Doyle’s coworkers said that while the scientists at LANL had no problem with the article, LANL management was upset. Doyle published his article on  February 1st of 2013, having been told by the staff who handled classification reviews that there was no classified information in his article.

             Around the time of the publication of the article, the LANL and their Republican allies on the House Armed Services Committee were trying to get funding for a new multibillion dollar facility at LANL. This new facility would manufacture the small plutonium spheres that form the heart of nuclear warheads. Despite resistance against the new facility from the Obama administration, a Republican Congressman managed to get an amendment attached to the bill for the project. According to the amendment, the facility had to be completed by 2024. Obama did sign the bill including the amendment. Appropriation of funds for the facility is still being debated. Obviously, a call for total nuclear disarmament could have a negative effect on support for the planned facility.

             Five days after the article was published, Doyle was told that senior LANL managers wanted copies of all of the more than one hundred articles that he had written during his time at the LANL. On that same day, Doyle was told that his article did contain classified information. Seven days after the publication of the article, the head of the classification review department told Doyle that his article needed to be withdrawn from publication because it contained classified information. Doyle was forced to give up his home computer so that all copies of his article could be erased. In addition, he lost his high-level security clearance. Doyle fought back for several months, protesting his treatment and the reclassification of his article by the LANL.

            Doyle was ultimate fired from his position at LANL on July 8th, 2014. LANL representatives claim that it all just part of a regular planned program of layoffs at the lab. Doyle and his supporters are skeptical of the LANL excuse and say that Doyle was fired improperly for political reasons. After all, his article was supporting the publicly expressed policy position of the U.S. President with respect to nuclear disarmament.
