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 |
