New designs for nuclear power plants seek to generate greater trust

(Kansas City Star) The new breed of Generation III nuclear plants aim to improve on those odds to one in 10 million with more redundant safety systems and the use of passive cooling systems. A key advantage of passive systems is that they don't require plant operators to take any action. "That's the whole point, because we tend to screw things up," said Dan Ingersoll, a senior program manager for Oak Ridge National Laboratory's reactor and nuclear systems division. "That really is the distinguishing feature between Generations II and III."...3/19

UT researchers help complete sequencing of brown tide species

(Knoxville News Sentinel) Steven Wilhelm, professor of microbiology at the University of Tennessee, and a team of researchers have completed the first-ever genome sequencing of the brown tide species. Wilhelm worked with Gary LeCleir, microbiology research associate at UT; Nathan VerBerkmoes, adjunct assistant professor of microbiology at UT; Brian Dill, a postdoctoral fellow from Oak Ridge National Laboratory; and Manesh Shah, senior research associate at the School of Genome Science and Technology....3/20

Experts reach out to sister city, evaluate Fukushima disaster

(Knoxville News Sentinel) "What we are debating, internally, with nuclear engineers I've talked to is what can they do to mitigate any further core melts or any further releases of radioactivity," said Jeff Chapman, a certified health physicist and research group leader at ORNL and chairman of the Oak Ridge/Knoxville chapter of the American Nuclear Society. "I don't think we have many answers to that."...3/19

What can be done with nuclear waste?

(Washington Post) Regardless of a country's chosen waste disposal method, all reactors' spent fuel starts in these pools and stays there, covered in water, for up to five years. Once the waste has decayed and cooled enough to be moved, there are four options....3/19

Stripes 'play key role' in superconductivity

(PhysOrg) Scientists at Oxford University and the Institut Laue-Langevin have used neutrons to probe the magnetic 'glue' thought to produce high temperature superconductivity and have identified stripes of magnetic moments and charge as the cause of a strange hourglass-shaped magnetic spectrum. Their findings, reported in Nature, are a step forward in the search for a model of high temperature superconductivity....3/21
