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.

         Deere-Jones warns that the NWS has produced an “inadequate and inaccurate impact assessment” on the effects of the airgun surveys on marine species present in these regional Marine Conservation Zones. He adds, “My recommendation is that consideration of the proposed survey, and all such surveys in UK waters, should be postponed until the information gaps referenced by Professor Popper have been filled and properly informed impact assessment decisions can be made.”
         The RFL report concludes with the recommendation that suitable alternative to airgun seismic survey, which pose a lesser threat to marine life, should be considered.
         U.K. Prime Minister Boris Johnson has put nuclear power at the heart of the country’s new energy strategy. There are currently plans to build up to eight new nuclear power reactors in the country. However, as yet, no permanent and safe storage method has been devised for spent nuclear fuel. It remains hazardous for many thousands of years and threatens human health and the environment. Two hundred and fifty thousand tons of this waste is currently in temporary storage around the world.
          The U.K. government favors deep geological disposal to deal with the most radioactive waste, whether deep below the ground or deep beneath the seabed. However, there are still many concerns about this sixty-five-billion-dollar facility proposed for in the Irish Sea, which has not been tried or tested and provides no guarantee of safety.
          The U.K. has used the seabed of the English Channel for disposal of radioactive waste. A German newspaper reported in April of 2013 that a team of journalists had discovered barrels of radioactive waste a few miles from the French coast just north of the island of Alderney in an underwater valley known as Hurd’s deep according to the International Atomic Energy Agency. Britain and Belgium dumped twenty-eight thousand five hundred barrels of nuclear waste into the English Channel between 1950 and 1963. In 1963, the British Radioactive Substances Act of 1960 went into effect and the dumping stopped.
           The existence of the barrels of radioactive waste was not a secret. Experts had assumed that the containers would have rusted open years ago. This would allow the nuclear material to dissipate in seawater to harmless concentrations. However, photos from an unmanned submarine showed that some of the barrels at four hundred feet were still intact. This prompted German environmentalists to call for their removal from the Channel. It is estimated that there are more intact barrels.
          The barrels contain an estimated seventeen thousand tons of low-level radioactive waste. Sylvia Kotting-Uhl is a German Green Party parliamentarian and nuclear policy spokesperson. She said, “I believe that at such shallow depths these barrels pose a high potential for danger. And it’s not for nothing that dumping in the ocean has been forbidden for 20 years.”
          Hartmut Nies is a German oceanic expert for the IAEA. He said that “If it’s not too complex, then of course they should be removed.”
         In response to a parliamentary inquiry from the Green Party in August 2012, entitled “Final Disposal Site Ocean Floor,” the German federal government stated: “The Federal Maritime and Hydrographic Agency (BSH), as part of its radioactivity monitoring in the North Sea, regularly carries out monitoring runs, which went into the British Channel Most recently in August 2009. The monitoring data contained no indication of emissions from dumping areas.”

          Zooplankton are the base of the marine food chain. They are extremely important to the health of the world’s ocean. Researchers have discovered that seismic surveys significantly increase the death rate of zooplankton in the three quarters of a mile range they tested. All larval krill were killed in the range of the test.
         The RFL’s report states that the NWS surveys will take place when zooplankton populations are expected to be high. These creatures provide a food source for a wide variety of organisms including baleen whales, basking sharks and fish. These species feed many other species.
         Many other marine animals also rely on sound for survival. Seismic testing can interfere with basic functions such as feeding, mating, navigation, and communications. According to the Zoological Society of London’s Cetacean Stranding Investigation programs, “Noise exposure can be a problem for a wide variety of Cetaceans-dolphins, porpoises and whales. Noise related impacts have also been causally linked to many cetacean stranding and mass stranding events globally.”
         The NWS investigation will focus on a survey area three to twelve miles Cumbrian Coast in the northwest of England in an area approximately one hundred square miles in extent. The proposed GDF may extend over an area fifteen miles square, deep beneath the seabed.
         This region is one of a number of designated Marine Conservation Zones in the Irish Sea. The region has protected habitats and is home to a variety of protected European species. These include sea turtles, minke whales, common and bottlenose dolphins and harbor porpoises.
         Joan Edwards is the director of policy at the Wildlife Trusts. She said, “The Irish Sea is rich in marine life, from soft corals and reefs that provide shelter for crabs and anemones to seals, whales and around 30 species of shark. Sandbanks and gravel habitats are vital nursery grounds for flatfish, sea bass, and sea eels, while also acting as a feeding ground for thousands of breeding seabirds. We are concerned about the implications of seismic testing in the Irish Sea, which evidence shows can be devastating for marine life.”
         Marine habitats are already under huge pressure from pollution, irresponsible development and bottom trawling. Climate change is also producing stress on marine ecosystems. The RFL report claims that many of the hugely important marine species found in the area have not been sufficiently studied for their sensitivity to seismic surveys.
        Tim Deere-Jones is a marine radioactivity researcher and consultant. He is the author of the RFL report. He said that NWS’s license application for the seismic survey is characterized by a ‘marked lack of transparency.’ The NWS’s application also shows a refusal to engage in consultation with the public and marine stakeholders such as fisherman. Deere-Jones claims that the NWS has carried out what is basically a private environmental impact assessment without any independent oversight.
         Deere-Jones says that NWS has ignored a comment from Professor Popper who is a leading authority on fish bioacoustics. Popper has warned of a clear “information gap” that makes it makes it impossible to draw a clear conclusion on the effects that these airgun blasts could have on marine animal behavior or health.

         The government of the United Kingdom’s Nuclear Waste Services (NWS) is preparing to carry out seismic surveys off the Cumbrian Coast between July and August of this year. They are trying to find a place to dispose of nuclear waste produced by Britain’s nuclear power reactors.
         A report commissioned by Radiation Free Lakeland (RFL), calls for these disposal plans to be delayed. The report claims that the impact assessment by the NWS is “deeply inadequate” and “lacking in appropriate scientific and academic rigor.”
         Seismic blasting is a process that permits scientists to gather data about the geography of the seabed. Loud, repetitive blasts of sound are produced by an underwater airgun. The echoes of the blasts are measured to map the underwater rocks. The airgun will be fired every ten to fifteen seconds throughout the survey period which will last about a month.
         The surveys have been commissioned by NWS. They will be investigating the possibility of locating a Geological Disposal Facility (GDF). Deep under the seabed, this facility will be used to dispose of the U.K.’s toxic legacy of highly radioactive spent nuclear fuel which is a byproduct of nuclear reactors.
         Shearwater GeoServices is the company whose work on South Africa’s ecologically sensitive Wild Coast was stopped by the high court. They are charged with carrying out the investigations of the Cumbrian seabed. According to a freedom of information request, a license of exemption to carry out these surveys was issued to NWS for ‘scientific research’ However RFL claims that the survey is not for ‘scientific research’ but to develop a plan for disposal of spent nuclear fuel.
          Marianne Birkby is one of the founders of RFL. She said, “We commissioned an independent report because we need to counter the PR spin from the nuclear waste industry who are calling the seismic testing ‘non-invasive scientific research.’” She argues that instead of seismic blasting for scientific purposes, the plan facilitates a commercial venture for a “deep nuclear dump for heat generating nuclear waste.” She went on to say that a limited company that wants to process even more nuclear waste from new nuclear reactor builds, Radioactive Waste Management (RWM), is behind it.
          Birkby said, “Despite the marine protections this part of the Irish Sea has, it is an outrage that independent environmental impact assessments have not been carried out. Protections clearly mean nothing when the nuclear waste industry wants to pave the way to a deep nuclear dump.”
         Chris Eldred is senior project manager for geosphere characterization at NWS. He said that “there is no requirement to undertake a public consultation for these surveys. We have undertaken marine environment assessments requested by Natural England and navigational authorities to assess any impacts and they have been satisfied that our activities are exempt.”
         Low frequency sounds generated by a single seismic airgun can carry over great distances, especially in deeper waters. They have been recorded at locations up to twenty-five hundred miles from the source. They can blanket areas up to one hundred and sixteen thousand square miles with noise. Studies have indicated that seismic surveys can impact entire aquatic ecosystems because they can disturb, injure or kill a wide variety of marine life.
