Wolves are divisive animals. To some, they are livestock-ravaging, child-endangering 120-lb. (55 kg) beasts that should be controlled through state-sanctioned hunting. Others believe they majestically embody nature in an almost spiritual way, and for this group, killing wolves seems one step away from offing Fido. "The big-bad-wolf thinking is not in line with what we understand about wolves and the ecosystem," says Mary Beth Petersen, a Minnesota attorney who e-mailed Millage after seeing a photo of him kneeling with his rifle over the wolf. But by the time hunting season ended on March...
...start a nuclear chain reaction, spewing out heat and radioactive by-products. When it has been used in a nuclear reactor, as some of the Chilean HEU had been, it becomes radioactive. Twelve hours before the earthquake, the NNSA engineers had overseen the fitting of 1,500-lb. (680 kg) protective impact limiters on the material, designed to shield it from the force of an explosion - or, indeed, an earthquake - and placed an airtight cask around the irradiated uranium. They felt confident the packages would not jostle around and suddenly go critical or leak. But how to get them...
...told, over several decades, the five permanent members of the U.N. Security Council distributed some 44,000 lbs. (20,000 kg) of HEU - enough for 800 nuclear weapons - to around 50 countries as diverse as Australia, Jamaica and Vietnam. Although that figure is a drop in the bucket compared with the estimated 4.4 million lbs. (2 million kg) of HEU in weapons and storage in the U.S. and Russia, the Atoms for Peace HEU is of particular concern because it is used in civilian reactors that are often poorly guarded and vulnerable to theft. As William Potter, director...
...Bieniawski's job to convince countries to give up their HEU and send it to either the U.S. or Russia. So far, the NNSA has removed a total of 5,935 lbs. (2,692 kg) of fissile material from 37 countries and has its sights on 4,190 lbs. (1,900 kg) more. To meet that goal, Obama has asked for the program's budget to be increased by 67% percent to $560 million next year. But many countries see HEU-fueled research reactors as symbols of prestige and don't necessarily share U.S. and Russian concern that fissile material...
...combat the "insider threat." All confirmed cases of illicit trafficking of HEU in the past 20 years have involved employees siphoning off material and attempting to sell it on the black market - such as the 1992 arrest of a Russian engineer caught trying to sell 3.3 lbs. (1.5 kg) of HEU at the Podolsk train station. All the cases involved minimal amounts...
