...cannot control the knowledge of how to make a nuclear bomb, atomic or hydrogen--we must control the fissionable materials needed to do so. If we don't want to live in "a nuclear armed crowd" (as one commentator has put it), we will have to stop blithely spreading uranium and plutonium around the globe under the guise of the "peaceful atom...
...from overheating, was automatically activated. That started a reactor "scram" or shutdown. Tons of water flowed into the reactor and out through the open relief valve. At the same time, malfunctioning instruments gave reactor operators misleading readings of reactor pressure, which made them believe that the core of enriched uranium was covered with coolant when it was not. The operators switched off the system on the assumption that it was no longer needed. The premature shutdown and temporary loss of coolant caused the reactor's fuel rods to overheat. They reached a temperature of around...
Although apparently none of the 100 tons of uranium fuel melted, the zirconium alloy cladding that surrounds the uranium rods was heavily damaged, the NRC said...
...topping $11 billion, and a net profit before taxes of close to a billion dollars, the Atlantic Richfield Company is one of the nation's largest oil firms. In 1977, it acquired the Anaconda Company, a leading mineral producer. Today ARCO's interests extend to copper, aluminum, coal, uranium, a few solar and geothermal energy operations, and even a London newspaper, The Observer...
...reactor's power center is its fuel core. Housed in a pressure-cooker-like reactor vessel, the core is filled with pellets of fissionable uranium packed in bundles of thin cylindrical zircaloy rods. Inserted into the core are still other rods, usually made of cadmium or boron, which absorb and retain neutrons given off by the uranium atoms-in effect, stopping the billiards and regulating the intensity of the reaction. To start the reactor, the control rods are raised to precisely calculated levels. The chain reaction begins, converting mass into energy and producing great quantities of heat...
