Obama's budget cuts off most funds for Yucca Mountain repository
The future of the Yucca Mountain nuclear waste repository appears grim; Obama campaigned against the project, which is already more the 10 years behind schdule; new scientific evidence showing that water flows through Yucca Mountain much faster than initially believed raises the prospect that the nuclear waste would leach over time

World's largest supercomputer will be used for nuclear stockpile research
IBM to build a 20 petaflops supercomputer, called Sequoia, for the Lawrence Livermore lab; a petaflop stands for a quadrillion floating-point operations per second; to put Sequoia’s computing power in perspective, what it can do in one hour would take all 6.7 billion people on Earth with hand calculators 320 years, if they worked together on the calculation for 24 hours per day, 365 days a year
