American researchers have shown that prospective magnetic fusion power systems would pose a much lower risk of being used for the production of weapon-usable materials than nuclear fission reactors and their associated fuel cycle. The researchers, from Princeton University, found that if nuclear fusion power plants are designed to accommodate appropriate safeguards, there is little risk of fissile materials being produced for weapons, either secretly or overtly. Their results have been...

Sandia National Laboratories is using its Ion Beam Laboratory (IBL) to study how to rapidly evaluate the tougher advanced materials needed to build the next generation of nuclear reactors and extend the lives of current reactors. Reactor operators need advanced cladding materials, which are the alloys that create the outer layer of nuclear fuel rods to keep them separate from the cooling fluid. Better alloys will be less likely to deteriorate from exposure to everything from coolant fluids...

Scientists have produced a previously unseen uranium molecule, in a development that could help improve clean-up processes for nuclear waste Scientists have produced a previously unseen uranium molecule, in a development that could help improve clean-up processes for nuclear waste. The distinctive butterfly-shaped compound is similar to radioactive molecules that scientists had proposed to be key components of nuclear waste, but were thought too unstable to exist for long....

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 discovered a new way in which seawater can corrode nuclear fuel, forming uranium compounds that could potentially travel long distances, either in solution or as very small particles. The research...

Research by a team of Sandia chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste. The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. “This is one of the first attempts to use a MOF for iodine capture,” said chemist Tina Nenoff of Sandia´s Surface and Interface Sciences Department. The discovery could be applied to nuclear fuel...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
'Omphalos' comes from the ancient Greek.
