The Threat Of Nuclear Energy


You are watching the control panels and gages for rector two. Sitting comely you think about how easy your job is. It is a joke! All day you sit around and watch the gages for reactor number two just to make sure they maintain their settings. You don’t even need to look at the gages either because a computer automatically regulates them without you. Life is so good. Suddenly all the sirens go of and the gauges and displays spin wildly in every direction. The ground shakes and you can hear the sound of a deep rumble. Unknown to you, the reactor’s cooling pumps have failed to cool the reactor’s core and in 3 seconds the temperature went from 280 degrees centigrade to 4,000 degrees ...

screeching, scraping, tearing sounds of a vast machine breaking apart. L. Ray Silver, a leading author who covered the disaster at Chernobyl, said that within the core, steam reacts with zirconium to produce that first explosive in nature’s arsenal, hydrogen. Near-molten fuel fragments shatter nearly incandescent graphite, torching chunks of it, exploding the hydrogen. The explosion breaks every pipe in the building rocking it with such power that the building is split into sections (11-13). You look down at your body and notice that it feels hot and your hands look different. Unknown to you a tremendous amount of neutrons are hitting your cells and taking chucks out of your skin.

a moderator slows the neutrons down enough to ensure that they will continually split more uranium atoms. At the same time, the moderator acts as a coolant. It keep the overall temperature about 300 degrees Celsius. Since the temperature at spots inside the fuel rods may be as high as 1,100 degrees Celsius, enormous amounts of coolant are continually needed to keep the core temperature at the proper level. When the plant must be must be shut down the control rods are lowered all the way back into the core. That brings the chain reaction to a standstill. The core cools, and steam is no longer produced (23-24). In all nuclear reactions use uranium and produce some plutonium.
Since ...
