USA taxpayers again forking out money for dodgy new nuclear reprocessing

Department of Energy moves forward with controversial test reactor, Science, By Adrian ChoFeb. 28, 2019 ,The U.S. Department of Energy (DOE) announced today that it will go forward with plans to build a controversial new nuclear reactor that some critics have called a boondoggle. If all goes as planned, the Versatile Test Reactor (VTR) will be built at DOE’s Idaho National Laboratory (INL) near Idaho Falls and will generate copious high-energy neutrons to test new material and technologies for nuclear reactors. That would fill a key gap in the United States’s nuclear capabilities, proponents say. However, some critics have argued that the project is just an excuse to build a reactor of the general type that can generate more fuel than it consumes by “breeding” plutonium…….
The VTR—also known as the Versatile Fast Neutron Source—would be the first reactor DOE has built since the 1970s. It would differ in one key respect from the typical commercial power reactors. Power reactors use a uranium fuel that contains just a few percent of the fissile isotope uranium-235 and is made to be used once and discarded. In contrast, the VTR would use a fuel richer in uranium-235 that would generate more high-energy neutrons as it “burned.” Those neutrons could be used to test how new materials and components age within the core of a conventional nuclear reactor, a key factor in reactor design. In principle, such a “fast reactor” could also convert nonfissile uranium-238 to plutonium-239, which could be extracted by reprocessing the fuel……https://www.sciencemag.org/news/2019/02/department-energy-moves-forward-controversial-test-reactor |

Ethics, Nuclear Power, and Global Heating – theme for December 2019
Ethics of Nuclear Energy Abu-Dayyeh (P.hD) Amman – H.K. of Jordan Ayoub101@hotmail.com E_case Society (President) www.energyjo.com [Extract]
Abstract:
This paper attempts to refute the myth of “clean nuclear energy”, and discusses the unethical impact on the environment of the overall process of the nuclear energy electricity production industry, from mining to decommissioning, through the problematic framework of “health risk analysis”, “economical feasibility” and “sustainability”. It also focuses on the economic and safety fragility of developing countries in the South to deal with big loans or a possible catastrophe, not to mention managing nuclear waste for a very long period of time.
Finally, the paper diverges all the inductions of the different criteria discussed towards inferring a global categorically imperative ethical perception based on a biocentric stance that takes United Nations recommendations into consideration, such as the “Precautionary Principle”, the declarations on Human Rights and the rights of future generations to a healthy and sustainable environment, in order to settle down to an “ecosophical” conclusion.
1- Introduction: The “clean nuclear energy” myth!
Nuclear energy is still one of the options used today across the world, thought to be a clean source of energy that produces neither CO2 nor other Ozone related pollutants into the atmosphere. However, it is now been verified that the complete fuel cycle of nuclear energy production is generous in producing GHG as well as CFCs; from mining and milling to fuel enrichment, constructing and operating the nuclear facility, transportation of nuclear fuel, safety and security measures, reprocessing and recycling the depleted nuclear fuel, manufacturing by-products, encasing and burying the nuclear waste and eventually decommissioning the nuclear facility and its surrounding environment, including the contaminated soil(1).
Concerned communities in Japan who are removing contaminated soil and conducting clean up operations are using independent researchers because they have lost faith in their government: “The roots of mistrust came out after authorities issued radiation readings that often turned out to be incorrect”(2). This comes as a proof that governments don’t consider life cycle assessment mechanisms in calculating accurate GHG emissions, insurance, cost of KWh of electricity produced or genome radioactive infuriation. Most of the research is government sponsored or controlled by nuclear commissions, thus falling in “conflict of interest” controversy.
The nuclear fuel cycle is a generous CO2 emitter that can exceed 288 grams of CO2 e/KWh, or (66)g as a mean value, even when existing studies fail to consider emissions of co-products (3) which cause global warming too. Research on light water nuclear reactors showed CO2 emission up to 220 g/KWh (4), yet this value is expected to rise as uranium ore grade worldwide is deteriorating by time. The USA ore grade average, for example, dropped from 0.28% U3O8 to 0.07 – 0.11% (1100 ppm) in 40 years (5). The complete life cycle assessment mechanism considered to calculate CO2 equivalent (CO2 e/KWh) in the previous analysis can raise this value significantly!
A comparative study on GHG emissions of thin-film photovoltaic electricity generation yielded a range of carbon foot print of 14-26 g/KWh under 2400 KWh per square meter per year, through a performance of 80%, for a life time of 30 years(6). A median value of carbon foot print for wind power was calculated to be 11 g/KWh(7), compared to the 66 g for nuclear without considering co-products emissions, uranium ore grade deterioration …etc.
The nuclear fuel cycle also produces chemical compounds that can harm the Ozone layer due to the generous emissions of CFCs during uranium enrichment. CFC 114 produced is an Ozone layer depletory, where as 93% of the CFC 114 released in the USA is from uranium enrichment (8).
Further more, the enrichment of uranium is a highly polluting industry during which U238 (Depleted Uranium) is produced; a heavy metal, 1.7 times heavier than lead, used in encasing ammunition among other things. It burns upon impact and 80% of its weight disintegrates into aerosol powder (half – radioactive life 4.5 billion years, the same as the Earth’s age) (9).
Regardless of these justified arguments, some might still argue that nuclear energy emits far less CO2 than some fossil fuels, particularly coal. However, we would like to counter-argue that claim on the basis that nuclear energy production is unethical on the bases of a set of criteria:
Health risk analysis, economic feasibility, sustainability, security and liability, which will be discussed in this paper. Additional arguments would be based on the “Precautionary Principle”, United Nations Declaration on Human Rights and the right of future generations in a healthy, safe and sustainable environment.
For those who might still believe that moral responsibility and ethical stances don’t change the world just have to wait and see how an ethics committee decision shaped the future of nuclear Germany!…………”
