16 US Ships That Aided In Operation Tomodachi Still Contaminated With Radiation (stripes.com)
mdsolar writes: Sixteen U.S. ships that participated in relief efforts after Japan's nuclear disaster five years ago remain contaminated with low levels of radiation from the crippled Fukushima Dai-ichi nuclear power plant, top Navy officials told Stars and Stripes. In all, 25 ships took part in Operation Tomadachi, the name given for the U.S. humanitarian aid operations after the magnitude-9.0 earthquake and subsequent tsunami on March 11, 2011. The tsunami, whose waves reached runup heights of 130 feet, crippled the Fukushima plant, causing a nuclear meltdown. In the years since the crisis, the ships have undergone cleanup efforts, the Navy said, and 13 Navy and three Military Sealift Command vessels still have some signs of contamination, mostly to ventilation systems, main engines and generators. "The low levels of radioactivity that remain are in normally inaccessible areas that are controlled in accordance with stringent procedures," the Navy said in an email to Stars and Stripes. "Work in these areas occurs mainly during major maintenance availabilities and requires workers to follow strict safety procedures." -
Russia Builds World's Largest Nuclear Powered Ice-Breaker
Hugh Pickens writes "Eve Conant reports that Russia's dream to dominate the Arctic will soon get a boost with a $1.1 billion nuclear-powered icebreaker 170 meters long and 34 meters wide. It's designed to navigate both shallow rivers and the freezing depths of the Northern Sea. Powered by two 'RITM-200' compact pressurized water reactors generating 60MWe, the world's largest 'universal' nuclear icebreaker is designed to blast through ice more than 4 meters thick and tow tankers of up to 70,000 tons displacement through Arctic ice fields. Why the effort and cost? 'Climate change is a pivotal factor in accelerating Russia's interest in icebreakers,' says Charles Ebinger. 'With climate change we are seeing a major change in the Northern Sea Route, which is a transport route along Russia's northern coast from Europe to Asia. Just in the last few years, with less and less permanent sea ice, maritime traffic across the Russian Arctic has risen exponentially.' The expectation is that the melt will continue, but there are still sections of route that would require icebreakers to keep it open year round. Icebreakers are an excellent example of a special purpose vehicle that is very poorly designed for operation outside its specific envelope. The key element is the rounded bow, a shape best suited to riding up on ice shelves and crushing them from above, causing the ships to roll from side to side in the waves when sailing on open water, making for a very seasick ride for the crew. Russia is the only country in the world currently building nuclear icebreakers, and has a fleet of about half a dozen in operation, along with a larger fleet of less powerful, diesel-powered icebreakers. The U.S. has been relying on a Russian diesel icebreaker to deliver supplies to Antarctica due to our own shrinking fleet of the cold-water, diesel-fueled vessels." -
Law of Armed Conflict To Apply To Cyberwar
charter6 writes "Gen. Kevin Chilton, the head of STRATCOM, just declared that the Law of Armed Conflict will apply to cyberwar, and that the US won't rule out conventional (read: kinetic) responses to cyber-attacks. This means that we consider state-supported 'hackers' to be subject to the Geneva Conventions and Customary International Law, including the rules of proportionality and distinction (i.e. if we catch them, we can try them for war crimes). Incidentally, it also means we consider non-state cyber-attackers to be illegal enemy combatants, which means we can do all kinds of nasty stuff to them." -
US Army To Invest $50 Million In Game Development
$50 million in funding has been approved for the Army to establish a unit that will develop games. The purpose of the games will be to train soldiers for various tasks, and they say there is no intent to compete with commercial games. We've previously discussed other efforts by the Army to integrate games into their training programs. "Col. Mark McManigal, the capabilities manger for gaming under the Training and Doctrine Command, said the selected game must provide low-cost training and must not require large number of technicians to run. It must also have a play-back function for after-action reviews, he said. 'One of the major events for training is to be able to capture all these events, good or bad, throughout the entire scenario,' he said. Trainers must be able to edit the game during play to change the difficulty level or add complexity to an exercise. For example, they must also be able to edit terrain to replicate training areas or combat zones, he said."
