• How seawater could corrode nuclear fuel
  

  Japan used seawater to cool nuclear fuel at the stricken Fukushima-Daiichi nuclear plant after the tsunami in March 2011 -- and that was probably the best action to take at the time, says Professor Alexandra Navrotsky of the University of California, Davis. But Navrotsky and others have since discov more

• Nuclear detector: New materials hold promise for better detection of nuclear weapons

  Northwestern University scientists have developed new materials that can detect hard radiation, a very difficult thing to do. The method could lead to a handheld device for detecting nuclear weapons and materials, such as a "nuclear bomb in a suitcase" scenario. "The terrorist attacks of 9/11 height more

• Graphene oxide gets green

  "We can make you and we can break you." If Rice University scientists wrote country songs, their ode to graphene oxide would start something like that. But this song wouldn't break anybody's heart. A new paper from the lab of Rice chemist James Tour demonstrates an environmentally friendly way to m more

• Structural characterization of the aqueous dimeric uranium(VI) species: (UO2)2CO3(OH)3−

  A combined theoretical and spectroscopic approach was used to refine structural data of the aqueous dimeric U(VI) species, (UO2)2CO3(OH)3−. Several isomer structures of this complex were already derived from previous X-ray absorption and NMR experiments (Szabó, Z. et al. J. Chem. Soc.-Dalton Trans., more

• Diffusion model of the non-stoichiometric uranium dioxide

  Publication date: July 2013 Source:Journal of Solid State Chemistry, Volume 203 Author(s): Emily Moore , Christine Guéneau , Jean-Paul Crocombette Uranium dioxide (UO2), which is used in light water reactors, exhibits a large range of non-stoichiometry over a wide temperature scale up to 20 more

• Measurements of 236U in Ancient and Modern Peat Samples and Implications for Postdepositional Migration of Fallout Radionuclides

  236U was analyzed in an ombrotrophic peat core representing the last 80 years of atmospheric deposition and a minerotrophic peat sample from the last interglacial period. The determination of 236U at levels of 107 atoms/g was possible by using ultraclean laboratory procedures and accelerator mass sp more
